    Here is a great comparison featuring the best naturally aspirated V8 powerlpant in AMG's history going up against AMG's newer turbocharged design. The M159 V8 in the SLS Black Series is a 6.2 liter naturally aspirated V8 and this particular car is tuned by Weistec along with featuring long tube headers. As Weistec Engineering demonstrated last month their SLS Black Series tune with headers is good for over 600 horsepower at the wheels on 91 octane pump gas. The E63 AMG is a 2013 rear wheel drive model. This car has a tune from Renntech along with RADO downpipes said to be good for around the 630 wheel horsepower range. Torque is in the turbo M157's favor with 735 lb-ft at the wheels. The M159 by contrast has 463 lb-ft at the wheels which is a very large difference on paper. Nobody will deny turbocharged motors are capable of big torque numbers. That said, the SLS Black Series features tighter gearing and a much higher redline at 8000 rpm. It's a motor with a definite breathing advantage at higher revs. Power and torque are in the E63's favor (at a lower rpm) but the SLS Black Series is roughly 600 pounds lighter. The SLS also has a dual clutch transmission whereas the E63 is using the MCT wet-clutch automatic. So what happens? A great race is what happens. The SLS gets a slight lead thanks to its shift speed advantage and manages to pull in the lower gears. Up top once the cars spend more time in gear the E63 is able to inch back but not enough to win the race. It's close at the markers with the Black Series slightly ahead. Simply a great run from two great AMG motors that employ different, yet very effective, strategies.

    Why does anyone need over 600 horsepower at the wheels in a G-Wagon? Come on now, nobody reading this site is asking that question. A 5600 pound German tank pushing 620 horsepower to all four wheels along with 547 pound-feet of torque is absurdly awesome. The motor is built by Eurocharged and is bored out to 5.7 liters with ported heads. The supercharger is Weistec's 3.0 liter twin screw which replaces the 2.1 liter OEM blower. Eurocharged added in some of their custom tuning and the result at all four wheels is staggering. Considering the drivetrain losses this is one of the strongest supercharged M113 V8's in the world. Simply great work by everyone involved.

    Good work here from GIAC for the 2014 A4 and Allroad models with 2.0T motors. GIAC managed to get some nice gains on 91 octane pump gas. The A4 test car put down 172 wheel horsepower and 213 pound-feet of torque completely stock on the AWE-Tuning Mustang dyno at all four wheels. What did the GIAC tune increase this to? 215 wheel horsepower and 254 lb-ft of torque for gains of 43 horsepower and 41 lb-ft of torque respectively. This A4 is a manual car and the numbers for an automatic will likely be a bit lower. GIAC also has a flash-loader available with a 100 octane race gas map (not dyno'd for whatever reason) as well as 'stock' and 'valet' mode for the situations that warrant it. The flash loader is not mandatory at $650. You can opt for a single map without the convenience of switching maps for $495.00. The convenience and safety offered with multiple maps and hand held flash loading more than warrants the price difference.

    4.2 liter V8 B8 S5 owners your day has come. APR released their Eaton TVS1740 based Stage III supercharger kit for the S5 and the power gains and performance numbers are very impressive. The S5 is not exactly a powerhouse in stock form putting out 274 horsepower to all four wheels. On 91 octane pump gas with the TVS1740 output goes up by 207 wheel horsepower to 481 wheel horsepower. The torque numbers thanks to the positive displacement blower also get a huge bump going from 288 wheel torque to 453 lb-ft at the wheels. The torque gain thanks to the TVS blower is instant which no doubt makes the S5 feel like a whole new car with a huge new motor. The 100 octane race fuel numbers are even more impressive with output at the wheels going to 550 and torque going to 501 lb-ft. So what does this do for performance? A stock S5 does the 1/4 mile in the mid 13's at roughly 105 miles per hour. On 93 octane with the APR Stage II supercharger the 1/4 mile improves to 11.24 @ 124.68. On 100 octane this improves even further to 11.16 @ 126.92. A night and day difference to say the least and what is even more impressive is that this was achieved with a manual transmission. So what is the price? Either $15,749.99 or $14,749.99 depending on the model year. If you want the full power capability you need an upgraded fuel pump which is not included in the kit. You will also likely need an upgraded clutch. Then there is also the intake and exhaust that should be upgraded to not become a restriction. Yes, this all becomes very pricey but with APR you know it will all work as it should and be reliable. Dynos and video below. 91 Octane: 93 Octane: 100 Octane:

    The Ferrari forced induction landscape is rather small. There are not many cars produced to begin with and it is not exactly easy to tune something like a 458 Italia for a forced induction setup. Most owners also are not going to tinker with their Ferrari. UGR (Underground Racing) is really the only company with results on the platform up to this point. So, enter Hennessey who as usual makes bold claims but with little substance. The pictures and videos certainly show what is a twin turbocharged 458. There is a short video that shows the car doing a WOT burst and it certainly sounds turbocharged. So where is the dynograph especially when one of the videos shows the car on a dyno? In Hennessey's defense UGR has not provided a graph either for their twin turbo kit which they claim puts out 700 wheel horsepower. However, UGR has built up a very solid reputation with their work in the Lamborghini world. Hennessey's reputation does not get the benefit of the doubt to say the least. Regardless, Hennessey claims 738 horsepower along with 532 lb-ft of torque for the kit. He also claims a 10.5 @ 137 mile per hour quarter mile which just like the horsepower claim is unsubstantiated. It is nothing more than an educated guess as a 458 Italia with a couple turbos should easily be capable of that performance and then some. Hennessey also does not provide pricing information and this is likely overpriced just like the majority of what Hennessey offers. Then again, UGR also does not provide pricing information. At this level it's one of those things where if you can afford the car you can afford the upgrades. Still, nobody likes to throw away money and in the Lamborghini world UGR clearly defines their pricing due to facing some actual competition. They may have some actual competition now in the 458 scene but until Hennessey demonstrates more than some short flyby videos the UGR kit is still the choice for the platform especially if it is cheaper. HPE700 Twin Turbo Performance Upgrade Available for the Ferrari 458 Italia, Spider & Speciale Power: • 738 Horsepower @ 8,400 rpm • 532 lb-ft Torque @ 5,600 rpm Performance: • 0-60 mph: 2.8 sec. • 1/4 mile: 10.5 sec. @ 137 mph HPE700 Twin Turbo Ferrari 458 Upgrade Includes: • Twin Ball Bearing Turbochargers • Fuel System Upgrade • Stainless Steel Inlet Piping • Dual Wastegates • Air-to-water Intercooler System • Dual Air Induction Filters • Stainless Steel Turbo Downpipes • Stainless Steel Exhaust System • Custom Oil & Transmission Lines • Professional Installation • HPE Engine Management Calibration • Dyno Tuning & Road Testing • Serial-Numbered Dash & Engine Plaques • Hennessey Exterior Badging • 1 Year / 12,000 Mile Limited Warranty Additional Upgrades Available: • CarbonAeroฎ Carbon Fiber Exterior Body Upgrades • Hennessey Monoblock Wheel Upgrade • Michelin Pilot Super Sport Tires • KW Adjustable Suspension Upgrade • Custom Interior Leather Upgrades • Carbon Fiber Interior Upgrades

    Look you have a point it's a tune only C63. It's definitely quick for what it is. Is it some monster? No and nobody should act like it is. If it was my C63 it would already have boost.
