    There is no stopping the Viper ACR. It is a track animal bent on destroying whatever dares come across its path. The M4 GTS? The Shelby GT350R? The Porsche 911 Carrera S? The new Acura NSX? The McLaren 570S? All simply lambs led to the slaughter. Emphasis on slaughter. Just look at what the Viper ACR did around Laguna Seca in the hands on Randy Pobst: 1. Dodge Viper ACR - 1:31.58 2. Audi R8 V10 Plus - 1:34.23 3. McLaren 570S - 1:34.58 4. Mercedes-AMG GT S - 1:35.30 5. Ford Mustang Shelby GT350R - 1:36.11 6. Acura NSX - 1:36.36 7. Porsche 911 Carrera S - 1:36.44 8. Nissan GT-R - 1:37.08 9. BMW M4 GTS - 1:37.66 10. Chevrolet Camaro SS 1LE - 1:37.78 11. Jaguar F-Type SVR - 1:38.75 12. Aston Martin V12 Vantage S - 1:41.77 It is almost a full three seconds faster than the next car up which is the Audi R8 V10 Plus. That is a beatdown. The Viper ACR is just on another level and it's amazing this car does not get more respect. Now, it is interesting to contrast MotorTrend's results at Laguna Seca to Car and Driver's results at VIR (Virginia International Raceway). The R8 V10 showed very weakly in Car and Driver's hands yet it is the second quickest car here with Randy Pobst at the wheel. When we say Car and Driver's hands we mean their staff who simply is not on Randy's level when it comes to driving prowess. Car and Driver's Lightning Lap is a good comparison but it is not as scientific as MotorTrend's (which also isn't perfect) due to taking place on multiple days with multiple drivers. MotorTrend uses Pobst at Laguna Seca with the cars running on the same day. That is a big difference. As is the fact VIR rewards power in the lap time more than the shorter and tighter Laguna Seca. What do we learn? That the M4 GTS get its ass handed to it by the Mustang GT350R yet again. It loses at VIR, it loses at Laguna Seca, and it is simply safe to say the GT350R is the superior track performer anywhere. Yes, at a fraction of the price. When you bring the M4 GTS asking price into the argument the car looks like a joke. Is its laptime respectable? Sure, if beating a Camaro SS that comes in at less than 1/3 of the money by a tenth of a second is respectable. The AMG GT S is cheaper, the 911 Carrera S is cheaper, the Nissan GT-R is cheaper, the Mustang GT350R is cheaper, and the Viper ACR is cheaper. What do they all have in common? They are all better performance cars than the M4 GTS. The Mercedes-AMG GT S deserves honorable mention beating the stout GT350R as well as the incredible new Porsche 911 Carrera S. Considering the GT S is not even anywhere near as hardcore as the GT model line gets, that is impressive. Enjoy the videos of the laps below with impressions from Pobst. The winner of the competition will be announced shortly. If we were to guess, the Carrera S is the favorite.

    This is the same BMW F80 M3 that recently broke into the 10's on the factory S55 turbochargers. In case you were wondering what kind of power it took to get there here is the answer. 585 horsepower at the wheels along with over 600 lb-ft of torque at the wheels. It looks like two different maps were tested as on the lower power figure runs the peak torque is substantially higher. Unfortunately, the full graphs are not posted so we can not get a look at the entire curve. Perhaps @Mike_f80nyc can post them. Still, impressive numbers. Especially the torque figures topping over 600 lb-ft at the wheels with a JB4 and methanol on the stock turbos. To BimmerBoost's knowledge, these are the highest power and torque figures from the factory turbos with bolt on modifications.

    How does almost 800 wheel horsepower sound from a 6 speed manual N54 with VTT GC turbos? Pretty nice, right? VTT hit 765 whp at 29.3 psi of boost but of course you can run less boost pressure. 28.5 psi resulted in 740, 25.4 psi in 693, and 22.8 in 655 to the wheels.

    It's been quite a while since the BimmerBoost.com E92 M3 was discussed. Where we last left off the vehicle was making more power and torque than any E9X M3 in the world and setting records. As a quick refresher, the car featured a built 10.0:1 compression motor with a sleeved S65 V8 block and a Vortech YSI blower. Yes, this build has taken years. Through the missteps, mocking, long nights, fabrication, tuning, and records set the S65 engine platform was pushed very far forward despite how uncooperative it is. Let's not forget this car made more torque than anyone else has up to today: And it also set the E9X 1/2 mile record with a 173.07 pass. This angered a lot of people in the community and let's just be honest ESS-Tuning in particular. ESS with their 'record setting' VT3 car at the same event as the BimmerBoost.com M3 could not even get close to its trap speed. At a subsequent event where the BimmerBoost.com M3 did not run ESS and the VT3 owner cheated by backing up as far as possible to get a running start to inflate the trap speed. It took them several manipulated tries like this but finally they eked out a trap speed a mile per hour higher. Yes, they cheated, because that's what it is and that is how these people are. They actually take pride in posting contrived records. This is all being mentioned to show you just how hard the car was pushed and what took place. The stock trans slipped as you can see in the dyno with the Vortech YSI at 18.5 psi of boost. If it held, just do the math. Even with 'only' 554 lb-ft of torque at the wheels well before the torque peak this is still the torque record today on the S65 platform. Do the math for the redline: 8400 rpm x 554 lb-ft / 5252 = 886 wheel horsepower. A conservative 886 mind you as the torque is still rising as the YSI really hit its sweet spot toward redline. It's a real shame we never saw a clean Dynojet run but the fact is nobody else was within 150+ whp of this car. Unfortunately, Dodson at the time did not have the DCT transmission upgrades available it does now and Kris Gagnon at SSP (South Side Performance) screwed this project over delaying it by over a year with his inability to deliver a working product and misleading me while utilizing my transmission as a model to get discs made overseas he could sell and now does sell. Showing this person's true colors will come in another article at a later date. So what happened? We pushed too hard on a platform BMW cut costs on. The fact of the matter is the S65 V8 is a weak design for boost unless tremendously reinforced. BMW loves to tout how light the motor is and how it is lighter than the iron block S54 it replaces despite offering more displacement and being a V8 but the S54 block is not only stronger it is built better. The S65 aluminum-silicon makeup while being light is very weak. Combine this with tight bore spacing, little to no material to work with, and a poor oiling system resulting from cost cutting going from the S85 V10 oiling system to the S65 V8 and you get a cheap, mass produced motor. The goal is quite simply to build it as cheaply as possible while still making it past the warranty period. Ask E9X M3 guys who did not get their bearings replaced and now are paying the price how they feel about BMW engine quality. It's amazing BMW gets away with this. While many things in this motor were upgraded and it handled more than anyone had ever thrown at the S65 we simply went too far because the goal was not to manipulate circumstances to set some bogus records that idiots on forums slurp up but to raise the performance envelope to unforeseen levels. No, it was not a tuning issue. Look at the pictures of motor below. The pistons look practically brand new. The problem was that the main bearings spun: Why? Tons of stress. A Vortech YSI is a monster blower that requires a ton of power to spin. This was not a build with a new crank as the displacement was kept the same. Increasing the boost only exacerbates problems. Things could have been done slightly differently to get it to work but you're always going to be putting more stress on the motor with something like a YSI at high boost than a V3si with low boost. Just the pulley setup alone is completely different and further off the front of the motor which doesn't help reduce various stresses. The other issue is the block flexing. My engine was built quite strong but in order to install sleeves you have to remove material. The idea is the sleeves add material and while the cylinders may be stronger the block as a whole becomes compromised due to how fragile it is to begin with. The block will not be sleeved this time around. Instead, Gintani advocates using a bedplate/brace. AMS does something similar with their GTR builds: AMS uses a billet aluminum piece but Gintani will be using a chromoly piece to brace the block: This should mitigate flex but additionally by switching to turbos stress on the motor is reduced as a whole. It will be possible to make more power at less boost without needing to manually turn a blower. A huge difference in efficiency alone with increased reliability. Furthermore, the factory crank will not be utilized. A new custom forged stroker crank will also take much more abuse than the factory piece: You will notice the stroke is 76.5mm which is a minimal increase over the factory 75.2mm stroke. This is not about displacement gains but simply increased strength and rod to stroke ratio. Technically, yes, it is a stroker build but you will notice those who went big on a stroke increase in the past and tried to add boost ended up with blown motors. That happened for a reason. What else does this build entail? - Mahle pistons - Ferrea intake and exhaust valves - Forged rods - WPC main bearings - BE rod bearings - Two turbos (specs will be provided later) - Welded and machined heads - Dodson build DCT trans - Water/meth - Upgraded fuel system - Carbon driveshaft - Upgraded oiling system - E85 tuning - Gaskets, fluids, etc. When we get to the tuning portion further details will be posted at that time. For now, stock DME tuning is looking likely but the Syvecs S65 standalone may be incorporated. To those who have supported this project and understand the work involved to push a BMW to these levels and that everything does not always go as planned, thank you. To those who have not I'd like to point out not only is BimmerBoost.com bigger than ever before but things will only continue to get better from here on out.

    Performance SUV's are popular and BMW loves producing as many SUV variants as possible to pad the bottom line. An X7 is on the way for this reason and BMW plans to create a 2018 X3 M model launching next year. Many of you have seen the spyphotos of this model testing. The X3 M will go head to head with the Mercedes-AMG GLC63 AMG. As the AMG M177 twin turbo V8 packs some serious muscle BMW will need the S55 motor out of the F80 M3 and F82 M4. The question is, will they fix the problems with it? They pretty much will have to. It just depends on if BMW intends to announce they made changes which publicly admits they screwed up. BMW is insecure, cheap, and petty so seeing them have to admit to design changes would be satisfying and deserved. Keep in mind the S55 motor making its way under the hood is a rumor floating around but what other motor will the car use to competitive? The S55 is pretty much the choice as BMW does not have the balls to give it a V8 and have the X3 M run circles around the X5 M.

    With MotorTrend wrapping up their Best Driver's Car 2016 competition having all the cars together provides for a great opportunity to do a big drag race. They have been doing this every year for the past six years following the competition and who can blame them for the extra content? Obviously, some of these cars are more at home on the roadcourse (*cough* Viper ACR *cough*) than the dragstrip and that should be the focus but this drag race is undeniably fun. While they call this the world's greatest drag race (such creative self-promotion guys) it does not take place on an actual prepped drag strip. They use the tarmac at the defunct El Toro airbase in Irvine, California. This surface does not lend itself well to the rear wheel drive cars and MotorTrend doesn't seem capable of putting on the world's best roll on race to get both perspectives. Ok, ok, enough nitpicking but it is important to highlight the conditions in a drag race. They throw in a Charger Hellcat and cut the Aston Martin (lame) for good measure and we're off. No surprise that on the dusty old runway the all wheel drive vehicles lead of the line. Now, as this is not done a dragstrip do not take these 1/4 mile times as representative of what you can hit on the strip. They are timing the cars electronically and the times are inflated due to this. We have yet to see a stock Huracan or R8 V10 Plus top 130 in the 1/4 mile on the dragstrip. Now, due to the traction issues let's list the cars in order of trap speed to truly get an idea of who is the fastest in a straight line: McLaren 570S - 132.0 Audi R8 V10+ - 130.3 AMG GT-S - 126.7 Viper ACR - 124.7 Acura NSX - 123.6 Nissan GT-R - 123.4 Jag F-type SVR - 122.7 Porsche 911S - 120.5 Shelby GT350R - 118.9 BMW M4 GTS - 118.8 Camaro 1LE - 114.2 The 570S is the real straight line champ and if you actually properly launch it you will watch it destroy an R8 V10 Plus in a drag race.

    We all know the Tesla Model S P100D is quick off the line. GPS test numbers showed 0-60 in 2.5 seconds and 0-100 in 6.5. The 1/4 mile trap speed on the VBOX used for the GPS numbers showed 124.5 GPS trap speed timing often inflates trap speeds versus real world drag strip numbers. That is the case here. The Tesla is still fast but on an actual strip runs 10.825 @ 122.93. The Huracan manages 10.843 @ 127.23. The two cars and very close and it really comes down to reaction time for the win. The Tesla is hard to beat right off the line but you can see just how much harder the Huracan is pulling past the 1/8 mile. From a roll, the Tesla has no chance. Certainly impressive performance from the P100D but it is a bit of a one trick pony.

    This should be a fairly even drag race. A tuned Mercedes-Benz R230 generation SL600 is capable of 11 flat in the 1/4 mile in the mid 125 mile per hour range. Going from a dig is good for the SL considering the massive torque from the twin turbo M275 V12 especially with an ECU tune. The GT3 RS is obviously much lighter. Roughly 1300 pounds lighter. That is a huge difference but the GT3 RS 4.0 liter flat-6 is naturally aspirated. It's a high revver and definitely not a torque monster. The PDK dual clutch transmission certainly helps. A standard 991 GT3 runs 11.3 @ 122.9 in the 1/4 mile. The GT3 RS is slightly quicker and faster but it also generates much more downforce increasing drag. On paper, this should be close. In practice the result is a bit odd as the SL gets a jump but instead of holding the lead the GT3 RS quickly mitigates it and pulls. The SL600 starts to reel in the GT3 RS at higher speeds which makes sense considering the drag of the GT3 RS aero pieces but the GT3 wins decisively. Maybe the SL600 simply has a weak tune?

    That is according to MotorTrend of course. After the testing of the lap times at Laguna Seca and the subjective impressions were factored in McLaren's 570S came out on top. The BMW F82 M4 GTS on the other hand finished second to last and we can officially call the car a failure at this point. If you want to check out the laptimes and videos click here. The subjective impressions rank the cars as follows: 1st - McLaren 570S 2nd - Shelby GT350R 3rd - Porsche 911S 4th - Camaro 1LE 5th - Viper ACR 6th - AMG GT-S 7th - Audi R8 V10+ 8th - Acura NSX 9th - Jag F-type SVR 10th - Nissan GT-R 11th - BMW M4 GTS 12th - AM V12 Vantage S The Nissan GT-R in 10th place is about right considering it is a soulless robot that best excels at going from a dig with power upgrades. That's really where it has made its name and please do not act like it is a great driver's car or track weapon. It's a heavy soulless robot with little driver involvement. The McLaren 570S on the other hand is a lithe and technologically advanced driver's tool. It's also light at 3188 pounds and incredibly fast in a straight line.

They are not run by enthusiasts and frankly do not deserve the business of enthusiasts. Posers on the other hand should continue to line up and bend over just to get f@#ked by dealers offering them the illusion that the artificially over inflated price they paid for their prancing horse is worth it. The overrated Italians are scared of the Viper ACR. They should be, it owned everyone. Ferrari even tries to hold it back. What a bunch of insecure Italian douchebags. Does the ACR really deserve to be 5th? Allow me to translate that for you: The Viper is loud and scary. It's the best driver's tool but we're a bunch of old men that have gone soft. We readily admit it's the best at doing what this competition is about, driving, but it's just too much car and too involving. Seriously, grow a pair MotorTrend. Reward Dodge for making a car that scared Ferrari and Lamborghini into staying home under the bed peeking out from time to time to make sure there isn't an ACR driving by. What about the F82 M4 GTS? Everyone should be sick and tired of hearing about this $134k failure from BMW. Just shut up about it already. It's hot garbage. The M in M4 GTS stands for Mistake not Motorsport. If that's the best BMW M can do for $134k when producing a dedicated high performance track car you might as well just shut the whole thing down and send everyone to work at 'i' instead. 'i' don't care anymore and neither should you. Let's to get real performance cars now and the one that should have won. The Shelby GT350R. Is it a higher performance driver's car than the McLaren 570S? No. Is it a better driver's car? Arguably, yes. When you factor in the amazing (and unique) powerplant along with the sticker price you scratch your head wondering how Ford pulled this car off. It's manual only. No dual clutch and no nonsense. Only real driver's should apply. Shouldn't that bump it up in a driver's car competition? How about that it beats up on more expensive cars? How about that it is the first production car with carbon fiber wheels? How about that the Americans are delivering engines that even Ferrari states are no longer economically feasible? Sure, it's not perfect but when you factor in the entire package the Shelby GT350R truly deserves the victory over something like the McLaren 570S that is purchased by spoiled brats. The fact it is American and the Americans are producing the best performance cars for the money today is just icing on the cake.

    Last year an article was posted showing the Z06 can go 9's with $2500 dollars in bolt on modifications. Well, you can even spend under that amount and still get into the 9's and over 140 miles of trap speed as the slip below shows. What is the recipe here? Halltech Stinger-RZ 18% underdrive pulley X-pipe Tune Drag Radials The tune is a 93 octane pump gas tune as well. Keep in mind 45 degree weather obviously helped tremendously but with winter approaching we are going to see a bevy of 9 second Z06's with basic mods.

    The Camaro SS arguably should be going up against the C63 and not the C43. It is impossible for it to go up against a B9 RS5 as there is no B9 RS5 on the market yet so the brand new B9 S5 is the logical Audi representation. The new S5 has a potent and impressive 355 horsepower and 368 lb-ft of torque twin scroll single turbo 3.0 V6. It should be an Audi tuner's dream. Speaking of which, it is going to need a tune to beat these cars. It is not surprising the Camaro SS is the quickest of the bunch. What is surprising is that the Mercedes C43 beats the S5. The Mercedes does not even have a true AMG powerplant but a 367 horsepower slightly tweaked M276 DELA30 twin turbo V6. Unfortunately, as this is Autobild and they do not understand that trap speeds would be very telling in a drag race comparison including rear wheel drive V8 but we only get elapsed times because they suck at this: Camaro: 12.60 C43: 12.84 S5: 12.94 The Audi brings up the rear which is surprising. Maybe it's a bit heavier than Audi let on?

    Major torque gains here from Renntech who has ECU flash tunes available for the W222 S550 models with the M278 4.7 liter twin turbocharged V8. Keep in mind this same M278 engine is in the S550 sedan as well as the S550 coupe except the coupe is only available as a 4Matic all wheel drive model. Renntech gets massive gains out of the motor. The torque figure is up over 700 lb-ft at the crank. At the wheels, they gain over 100 lb-ft of torque from 2000-4000 rpm. In a heavy car like the S-Class this will definitely be felt. Peak horsepower increases by 59 horses at the wheels. The power gains level off somewhat toward redline but there are gains throughout the entire curve and namely down low. A tuned M278 is a bargain compared to the much more expensive AMG models. Not to mention lighter.

    622 naturally aspirated horsepower out of the LS7 V8? That is just absolutely insane power without any boost. It's also making 546 lb-ft of torque at the wheels. This motor is a 429 cubic inch V8 built by Katech with 13.0:1 compression pistons. That explains why it has to run E85 fuel. It also has a Katech K501 cam, MSD intake, and full exhaust. Oh, and it goes into a car weighing ~2800 pounds. Awesome? Awesome.

    You have to respect how Underground Racing does not give up an inch to anyone. If a record falls, they quickly take it back. Heffner has been learning this the hard way for years and recently ETS got a taste of UGR's relentless record pursuit topping their standing 1/2 mile world record set earlier by their GTR this month. The record previously was 244.83 miles per hour and now is 247.25 miles per hour. The next milestone will be topping 250 in the 1/2 mile it looks like but these cars are getting so absurdly fast how much further can things go?

    There are turbo upgrade options out there in the AMG 5.5 liter V8 world. Most of you know about them and they are solid options but there is no true value option. Well, Pure Turbos decided to enter the M157 market with an upgrade for the OEM turbo housings. What is the pricing? How much power? These details are not available yet but will be soon: The main thing to take away here is that more competition is a good thing and Pure Turbos will likely offer the best turbo upgrade value in the segment.

    This is awesome to see. You may be asking, why track a luxury car weighing over 4500 pounds? Well, why climb Everest? Because it's there. Tracking the F01 7-Series actually can be quite a lot of fun especially when you hang with lighter cars wondering how that is happening. @tidalk went to a Thunderhill track day with his 750i equipped with H&R springs on the M-suspension but not on race tires. His car has a cat back exhaust as well. What's cool to see is that the boat did well. At 2:37 you can see him pass an S2000 with the S2000 owner probably wondering what is going on (along with where his torque is). At one time tracking a BMW 7-Series was not crazy as the 7-Series was the best driver's car and the lightest in the segment. BMW got away from their traditional recipe for success but it is still cool to see an owner using a 7-Series for something other than comfortably sitting in traffic. He plans to add race pads to avoid fade along with race tires next time out which will certainly lead to surprising more people. Awesome.

    12.0 in the 1/4 mile? Yep, from a Cobb tuned Porsche Macan Turbo. It sure looks like the massive torque gains Cobb displayed are the real deal. Not that there was ever any doubt but it is great to see track times supporting gains on a dyno graph. The results in the slip are on a Cobb 100 octane OTS race gas file. The race gas tune certainly makes a difference over 93 octane and especially 91 octane pump fuel. There are three passes here and you can see the consistency. Three 12.0X passes and three 111.XX trap speeds. The SUV is launching very well with 1.64X short times. With additional bolt on modifications or just cooler weather this is an easy 11 second SUV. Car: 2015 Porsche Macan Turbo, 6,6xx miles, Cobb tune 100 octane file, BMC filters with lids on, full weight including spare and tools with about 1/4 tank of Sunoco GT260 100 pump gas. Options that may matter: Chrono, PTV, SE AS, 20 inch spyder wheels with a/s tires. 39R 36F. Traction control off Conditions: 70F, 30.21BP, 63%RH, track sits at 1,230 feet so overall DA was 2,105

    Almost $200k for a Nissan GTR? No thanks. If you are someone who just has to have the Nismo version it will cost you $25k more than it did last year. Why is a platform a year older priced $25k higher than where it was previously which already was exorbitant? Because Nissan says so. You get some minor changes including a new grille, an improved interior, and a larger touchscreen. Power and torque remain the same at 600 and 481 lb-ft respectively. Nissan apparently is bridging the pricing gap between the GTR Nismo and the Porsche 911 Turbo S but the GTR was respected for value and the GTR does not lend itself to price hikes at the end of its lifespan. If you are considering this car do yourself a favor and buy a used GTR or just a standard 2017 GTR, tune it, and laugh at anyone dumb enough to waste an extra $100k+ on Nissan's aging robot.

    What a freaking beast! It looks mean, it sounds mean, and the dyno shows it is mean. A 4.7 liter twin screw blower from Kenne Bell is certainly huge but Boost Works gets it to fit under the hood of this 2015 Mustang GT Coyote. It's a good thing they do as the result is phenomenal. How about 1318 horsepower to the wheels along with 1028 lb-ft of torque at the wheels? Just look at that torque curve. We're talking over 800 lb-ft of torque instantly here. No waiting for an impeller to spin and no need for anything to spool. Just straight raw American muscle! Obviously this motor is built to handle the 31 psi from the blower. Here is the mod list: Kenne Bell 4.7L Liquid Cooled supercharger Bigun inlet with Dual 106mm TB MPR Engines built Coyote JW TH400 Automatic with 9.5" converter G-Force 9" IRS rear end with Strange diff G-force half shafts 20 gallon ice cell with separate hot water return holding tank Rule pump with -16an lines (6gpm flow) JPC Racing AEM Just a hell of a build and a hell of a car.

    Kings Performance is building a twin turbo 2015 Mustang GT Coyote and the goal is over 1000 horsepower. They are not done yet but what they have done so far is simply beautiful. BoostAddicts all around the world are going to appreciate this. This is an automatic 2015 GT with the KP1000 package. They are using a pair of large Precision turbochargers which look right at home in the engine bay. What are the engine build specs? How much boost? What fuel? How much power? That will all be answered when it is finished. For now, enjoy the photos.

    Syvecs continues their impressive rollout of ECU's across platforms. Where they have a significant edge on competitors (such as this one) is that their hardware supports direct fuel injection as well as dual clutch transmissions as we have seen in Huracan/R8 applications. You can see the Syvecs kit working on a 991.1 Turbo S in the video below. It is going into two Porsche 991 Turbos in the Middle East so we can expect to see it in action on the drag strip in a couple months. Syvecs mentions PDK transmission control such as clutch pressure. Pairing this ECU with the Dodson PDK upgrade sounds like a good recipe for success when launching hard with big power. The Syvecs setup also supports six additional port fuel injectors which is a good way for guys to get around direct injection fuel system limits. Pricing has yet to be announced this 991 Turbo plug and play ECU should be available for purchase relatively soon.

    What is this? Basically, an updated Ferrari FF. They ditched the V12 and all wheel drive here creating a rear wheel drive hatchback powered by Ferrari's F154 twin turbo V8. It is not the California T's 3.8 engine but it shares 3.9 liters of displacement with the Ferrari 488 GTB. The FF's engine is a naturally aspirated V12. Ferrari still offers all wheel drive with a naturally aspirated V12 in the GTC4Lusso (with compression bumped to 13.5:1). The GTC4Lusso T has 78 horsepower less at 602 but more torque with 560 lb-ft which is 46 lb-ft more than the V12. Honestly, the turbo V8 makes more sense with all wheel drive thanks to the torque benefit than the naturally aspirated V12 but someone at Ferrari must know better. It is a good looking hatchback and a four-seat Ferrari is undeniably cool but why get rid of the all wheel drive for the V8? Lighter is great but it should be the V12 with the lighter rear wheel drive layout and the V8 turbo with all wheel drive to help put down the torque. Imagine throwing a tune on top. Definitely a cool car and something different from Ferrari.

    This is a nice little chart that shows the capability of forged rods versus the factory pieces in the Volkswagen MKVI GTI 2.0 TSI engine. It's always nice to see upgraded forged pieces compared to their factory counterparts and the rods are a known weak point for the 2.0 TSI. Just look at how much beefier the IE rod is. What does it get you? Capability to rev higher as well as support more torque and horsepower: While the factory rods are a ticking time bomb over 400 lb-ft of torque the IE rods will handle 800+ lb-ft. You can also rev higher of course and the associated hardware is upgraded as well. It would have been nice if they listed the weights but you will often times find aftermarket forged pieces to weight the same or even be lighter than factory internals despite offering far more capability.

    Awesome numbers here from a built motor MKVI Volkswagen Golf R. GoodSpeed performance did the engine build which includes CP Pistons and Carillo rods. They threw an APR Stage III turbo kit with the Garrett GTX2867R turbocharger on top. The result is 517 horsepower on a MAHA dyno which is a popular dyno in Europe. Mod list: Built engine by GoodSpeed Performance APR Stage III GTX2867R Milltek catback CP Pistons Carrillo Rods APR intake APR intercooler APR fueling upgrade South Bend Clutch It would be nice to know the fuel this was done on but if you want a 500+ horsepower Golf R the APR Stage III kit will help get you there.
