    CARB (California Air Resources Board) is doing its darndest to ruin performance cars for everyone. What is the problem? CARB is adopting standards for 2025 that automakers believe are far too strict. Why is this a problem? First of all, automakers already stated they simply can not meet the previously proposed standards. Secondly, the rest of the states in the union would be forced to acknowledge CARB's decision. That means even if you do not live in California CARB would still be able to push your state around. Imagine for a moment a new car coming out with a lot of horsepower that is very efficient and meets EPA standards but does not meet CARB standards. Effectively, there would be two sets of emission standards in the USA but the CARB standards could force that automaker to abandon selling the car in the United States or even worse not bother producing it. Want to know what is truly troubling? Arizona, Connecticut, Maine, Maryland, Massachusetts, New Jersey, New Mexico, New York, Oregon, Pennsylvania, Rhode Island, Vermont, Washington, and the District of Columbia all decided to agree to CARB's standards. That means many of you are not exempt from California's eco-nazis even if you do not live in California. CARB gets away with setting federal standards as it pre-dates the EPA and a waiver under the Federal Clean Air Act means their emission standards must be recognized by other states. What will happen? Who knows. The Trump administration froze EPA grants to CARB hitting them where it hurts. The Trump administration also cut funding to the EPA. The Obama administration on their way out rushed approval of new EPA standards that align with CARB prior to Trump taking office. CARB blames the automakers: The White House believes California is going too far: As you can see, this is all pretty messy and will involve a lot of lawyers on taxpayer dime to sort out. The best case scenario is that CARB's waiver is revoked effectively neutralizing their power. The worst case scenario is two standards floating around which carmakers simply decide not to even bother with and stop producing performance cars altogether for the US market. Thanks a lot California.

    A recent article about a Mustang dyno run for the Alfa Romeo Giulia Quadrifoglio exposed a large flaw in traditional dyno thinking. On this website most readers know that you can not just grab a graph from one type of dyno and compare it to another dyno and expect the numbers to be uniform. Unfortunately, the average person does not understand this which is what led to someone putting out an article stating the Giulia Quadrifoglio is not making its stated output which sets understanding of dyno runs back instead of helping educate. Let's start with the idea that cars suffer from 15% drivetrain losses. Where did this idea start? Why is it 15%? It originated with the Dynojet and became a rule of thumb on automotive forums for manual transmission cars. The percentage changes based on if the car is automatic (20%) or even all wheel drive and automatic (25%). The problem here is that while the conversion factor works well to extrapolate crank horsepower from peak Dynojet figures at the wheels that is not the way drivetrain losses work. First of all, losses are not static. There is no one set figure for losses. What does this mean? It means that your losses in 5th gear at 8000 rpm will be different from 2nd gear at 2000 rpm. The loss figure will change based on rpm, load, and even what accessories are running. Stating all manual cars suffer from a single set figure is flawed for this reason. Not to mention that figure only works on the Dynojet which is inertia based. BMW M cars used to follow the number exactly back when they were naturally aspirated: E46 M3 S54 Displacement: 3.2 liter Horsepower: 343 Torque: 269 lb-ft Wheel Horsepower: 280 Wheel Torque: 235 E92 M4 S65 Displacement: 4.0 liter Horsepower: 414 Torque: 300 lb-ft Wheel Horsepower: 350 Wheel Torque: 254 lb-ft 85% of 414 horsepower is 351.9. Notice the E92 M3 is almost exactly at 15%. DCT models would actually dyno slightly less than manual examples due to the wet clutch dual clutch having higher losses. For the E46 M3 85% of 333 horsepower is 283.05. Again, the E46 M3 is almost perfectly at 15% losses on the Dynojet. It's almost scary how consistently close BMW was to this figure. Now, in comes the turbo era. Let's see what happens when we get to the F80 M3. F80 M3 S55 Horsepower: 425 Torque: 406 lb-ft Wheel horsepower: 427 Wheel torque: 429 How is the S55 engine producing more horsepower at the wheels than it is rated at the crank by BMW? Does the F80 M3 have a magical transmission with negative losses that somehow adds power? Of course not. The DCT transmission in the F80 M3 works the same way as the DCT transmission in the E92 M3. What happened was the 15% Dynojet loss rule went out the window when the turbo power war started. BMW is able to claim a lower number to not push an output war on paper yet delivers far more where it matters, to the tires. The drivetrain losses are still about the same for the transmission and rear wheel drive layout as the previous generation despite it no longer lining up with the crank horsepower figure which is practically meaningless. How does this all look on a Mustang load bearing or eddy current variant? Well, very different. While the Dynojet is spinning a drum of a set weight and calculating the result based on how quickly that weight is spun the Mustang dyno creates load. Why is this important? Because it simulates real world conditions which is great for tuning. A tuner can provide all kinds of different scenarios. The spool on the Mustang for a turbo motor will look different than on a Dynojet. Often time real world spool is much quicker than what is shown on a Dynojet graph due to load which generates exhaust gases more quickly for the turbochargers. Note: Dynojet operators can optionally eddy current load control as well which muddies comparisons further. The other day BimmerBoost posted an article on VF-Engineering's F87 M2 ECU flash software and provided Dynojet runs. Let's take a look at the same M2 running the same Stage I software on a Mustang: Now the Dynojet: 269 rear wheel horsepower for the Mustang and 331 rear wheel horsepower for the Dynojet on the baseline figure. That is a difference of 62 horsepower at the wheels or 18.7 %. If you take that 18.7% difference and apply it to the tuned run on the Mustang which shows 287 to the wheels you get 354 horsepower. Almost exactly what the Dynojet tuned run shows. This is not an exact science as you can see. However, if you were to dyno cars all day on the Dynojet and on this Mustang you would see the runs follow very closely to the ~18% difference between the two. So is that it? Just convert Mustang runs by 18.7% to get a Dynojet number? No. Things actually get very muddied due to the games tuners play. Here is an example. The new Porsche 991.2 Carrera S on a Dynojet: 380 horsepower to the wheels. Now here is a 991.2 Carrera S on a Mustang from AWE-Tuning: Why does the Mustang dyno show more power now? Because it is being corrected to read higher. People do not like low numbers and high numbers are better for marketing. BoostAddict asked AWE-Tuning what their correction factor is but they would not share it with us. You can see it is reading VERY high and higher than a Dynojet though. In this instance it is better to focus on the delta which you will often hear tuners say. That means the difference between the two runs as comparing the peak figures to other runs on other dynos is pointless due to the unknown correction factor. Good for marketing, bad for those who want relevant figures to compare with. It can also be very bad for consumers. Why is that you ask? Because some people will dyno without a correction factor and then change the correction factor to show larger gains. A good example of someone who plays with the numbers is Vivid Racing: http://www.bimmerboost.com/content.php?4252-Inflated-numbers-Vivid-Racing-claims-407-wheel-horsepower-for-exhaust-and-VR-ECU-tuned-E9X-M3-S65-on-a-Mustang-dyno They claim 407 wheel horsepower for an exhaust and canned tune on a Mustang dyno for the E92 M3. Anyone who has an E92 M3 (like me) and has had these modifications and dyno'd the car knows this is impossible. It looks good for someone who doesn't know that though and wants to buy parts thinking they make a ton of power, right? Always keep in mind when you see figures from a company or tuner you should question them. Independent runs are the best to go by as the person usually isn't trying to sell you anything but just share their results. Also remember the Mustang can be configured like most dynamometers to read whatever the operator wants it to read. If vendors and tuners did not play with dyno runs for sales we would have a great resource to work with for comparisons and so forth. You can not trust all tuners to do so. Fortunately, VF-Engineering has no dog in the fight and provided us with a variety of runs showing the difference between their Mustang and their Dynojet. Yes, they have both. That is the proper way to do it. One dyno for tuning and one for marketing. Rather than correcting figures with whatever percentage generates the most sales they show the uncorrected runs on both machines so people can learn from and reference the pulls. BMW 335i (N55) Stage TWO Dynojet: Mustang: An 18.2% difference between the peak horsepower on the tuned figures. There will be variance from run to run, day to day, fuel to fuel, gear to gear, etc. Ultimately, remember, while dyno runs can tell you a lot about a motor or modifications they can also mislead people. Even worse, people can read them incorrectly and spread misinformation or manipulate them to sell parts. A dyno is just one, albeit important, piece of the performance puzzle.

    BoostAddict member @The Ghost took his C6 Z06 to TX2K17 and had a bit of fun. His Z06 has upgraded heads, an aftermarket cam, intake, and is tuned on E85 ethanol. The car is in the ~600 whp range and definitely is making efficient use of its power. The first video has the Z06 run a single turbo N54 said to have a GT35R turbocharger. The Z06 dispatches it rather easily. Up next is another Z06 with a cam and bolt ons plus a 150 shot. Surprisingly, this Z06 has trouble until the bottle pressure is up at which point there is a good run between the two. This nitrous setup needs to be dialed in a bit better. A bolt on ZL1 LSA tries its luck next. The driver is either asleep or that car is a waste of gas. The second video below has more runs. First up is a second generation CTS-V LSA with bolt ons on E85. Not much of a race. Next up is a Honda S2000 with a Precision 6766 turbocharger. This is a light package that should be strong on the highway. It isn't. Another 335i joins in and possibly is single turbo. If so, it's time for a bigger turbo or a better setup. A GT350 Mustang tries its luck next. Suffice it say, time for boost. The final run is a ZL1 LSA with bolt ons and it holds off the Z06 when given the hit. A follow up run has the Z06 pull pretty easily. Overall, this is a very stout C6 Z06 for the mods stated.

    Last month BenzBoost reported that Pure Turbos was working on a turbocharger upgrade for the new 4.0 liter M177 and M178 motors under the hood of the W205 C63 and C190 AMG GT respectively. Well, now we have the results for the M177. How does 634 horsepower and 608 lb-ft of torque at the wheels sound? On pump fuel no less? No methanol, no E85, just what you can easily run every day. The other modifications are downpipes and an aftermarket exhaust. That's it. Considering the heft of the C63 the added torque will be appreciated. Plus, F80 M3's are showing strongly so an M177 turbo upgrade is a good idea for W205 C63 owners who want to easily dispatch tuned competition. As for the M178 under the hood of the AMG GT, results for that will have to wait for now until someone does the upgrade.

    PTF (Pro Tuning Freaks) Bootmod3 software is getting quite a bit of attention and deservedly so. It fills an important void with newer turbo BMW's offering features and remote tuning that were not previously possible through a flash tune. This F26 M40i has the Stage 2 PTF N55B30T0 software which is modified slightly. The full mod list is below the video but let's look at how the car does against some stout BMW rivals. A ZCP or Competition Package F80 M3 is up first. Keep in mind, the M3 is much lighter sending power to the rear wheels. The X4 actually wins from a roll! BimmerBoost would have bet money the M3 would pull up top. This M3 does look like a manual example however and the driver may need to work on rowing those gears. Next up is the Active-8 tuned 335 GT but the camera angle makes it tough to see how the car does. What is clear is that the X4 M40i pulls it. You also get a three way between the 335 GT and a JB4 tuned F15 X5 xDrive35i. Against the X4 M40i pulls. The X5 and the X4 square off for a final run but the X4 easily pulls again. Who knew an X4 M40i could be this quick? X4 M40i (N55 engine) 18,xxx miles with the following mods - ECU unlocked for BM3 by EnzoRacing / Enzotuned.com - Bootmod3 STG2 OTS Map (Slightly Tweaked) by ProTuningFreaks (First X4 M40i Tuned in the World and Flash that works) -CTS Turbo FMIC installed/tweaked by AIMPerformanceNJ @ AiMPerformanceNJ Custom Catless DP Versus - F80 ZCP Stock 30 roll - F30 335 GT w. downpipes & ActiveAutowerke active-8 piggyback on map7 - F15 X5 35i w. downpipes, dmetuning bef/jb4 map2 & 2gals of E85

    Was wondering if the white M2 that was driving down Huffmister and Kluge on saturday is on here. We got a couple of good pulls in. The m2 was quick and deff not stock. We were on the way to get propane for a crawfish boil.

    Vendors go about their online business in different ways. Some choose to stay out of it and just let their products do the talking. Others are very loud and constantly involved in social media and forum flame wars touting their product as the best. Often times those who yell the loudest are the most desperate for attention. Take Dime Racing as an example. Yes, the same Dime Racing that Weistec took to court. That matter has since been settled with undisclosed terms but Dime Racing continues to engage in some very shady behavior online. Last year Dime was caught trying to take credit for what was actually Weistec's performance on social media. Before that they used a Weistec dynograph claiming it was their own. Now they are going after Pure Turbos. Why? Because Pure Turbos entered the M177/M178 turbo upgrade market and is showing great results for less money. AMG modding is where Dime operates and a new competitor offering a better product for less money must be destroyed online rather than beaten through honest competition. The trolls were let loose: Pathetic, right? First they claim the Dynojet numbers are manipulated and a fabrication. Clearly someone needs to read the recent BoostAddict article on Dynojets vs. Mustang dynamometers. Secondly, they say Pure Turbos should 'prove it' and race them. Yes, seriously, they ask Pure Turbos to race a customer car without permission for some stupid internet grudge match. Pure Turbos being a responsible and professional company laughs this off and then the troll claims they backed out. Unbelievable. This goes on further where the Dime trolls imply this turbo upgrade will blow your motor. You get an idea of the pattern. The whole reason for this weak trolling attempt is to try to discredit a new option that is showing very well for less money. Pure Turbos is to be commended and let's just say we are all glad they do not race internet trolls in customer cars but instead let the performance numbers do the talking. This type of thing happens more often than you think. In the past, a tuner who took a similar approach was MHP and the owner actually asked BenzBoost to create troll accounts so the owner could go on a certain forum and try to undermine the competition. BenzBoost declined and MHP is now history. This same sort of thing is going on today with Dime having troll accounts on certain forums that specifically attack competitors. We know of a certain tuner that is sick of it and you can probably add Pure Turbos to that list. Maybe Dime Racing has an M177 turbo upgrade that works now (Eurocharged dumped them due to issues). Maybe their tuner isn't committing felonies any longer. Maybe Rod Shegem (http://rod-shegem.com) is not stealing money. What is clear is that a black cloud and negativity seems to follow Dime Racing wherever they go.
