    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.

    It is no secret that the new Stingray is already doing some incredible things in the aftermarket. Vengeance Racing in particular has been pushing the platform hard with the world's fastest boost only LT1 1/4 mile run hitting a blistering 144 miles per hour of trap speed. ] This VRSC690 package is a bit more mild than the record setting supercharged setup but it uses a similar centrifugal blower with several different options. You can choose from an ECS, Procharger, or A&A head unit. The dyno results below show an ECS unit and the output is 592 wheel horsepower on pump fuel. That is from the base kit with no modifications. What does the kit include? American Racing long tube headers, catted x-pipe, spark plugs, ECU tuning, and of course the supercharger and piping. The total price for around 600 wheel horsepower is $9999.00 plus installation. That is not bad at all and there is room to grow with race gas, higher boost, etc. Dyno results, specs, and pictures below.

    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.

    Volkswagen seems determined to repeat its mistakes. For whatever reason they are ignoring their history in the USA and ignoring the failure of the first generation Phaeton. Why? Well, they have the money to burn so if they fail again launching a premium priced VW model in the USA it really will not do much else other than give the US operations a bit of a black eye. New CEO Michael Horn will be the one who that will be held accountable if the Phaeton fails again. Horn wants to connect the German and American Volkswagen markets more directly. Well then why not bring over the models they sell in Germany that they do not sell here? People are interested in the Amarok pick up truck, there's a good place to start in the pickup crazy American market. He says the truck is too small compared to something like an F150. The market doesn't need another F150 it needs a compact truck. Does an $80k+ premium luxury sedan that will compete with Audi's offerings really make more sense than an affordable compact diesel truck? What about the Scirocco? We are not good enough for that car either? Michael Horn is a German and he has a good idea of how the brand does in Germany. However, this is not Germany. The one good sign is that Michael Horn says he is about the 'peoples' car and increasing volume with mainstream cars. Then give us the damn mainstream cars! He does not want to take the brand upstream but make it more mainstream. Good. So how in the world does the Phaeton accomplish that? Why say one thing which is the right thing to say but then do the wrong thing by taking the brand too far upscale? It just does not make any logical sense. Hopefully Michael Horn is able to turn around the US Volkswagen operations but this will not be accomplished with a Phaeton. Unfortunately, the Germans just do not seem to be listening to the Americans. Source

    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: • CarbonAero® 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

    I think the marketing audience is not on this forum. People that Buy Dinan, GIAC and Renntech typically wouldn't consider a BB Flash, Cobb or JB4. They just want to go into a facility and get their car coming out a few hours later with better performance. Most of these would probably come from other platforms that know that they had good luck with that tuner before. The Dyno sheet looks pretty close to a Cobb OTS Stage 1+ or 2+.

    Ok...so power gains are similar to the JB4 or a Cobb with a protune. Maybe a little more power, but that's just being a little aggressive to get an extra ~20whp without doing other upgrades. Mike@Renntech I'll be honest that price does seem extremely high considering the Cobb Flash is $900 and offers a handheld that can be used for other features including datalogging. What do you offer in terms of re-flashing/tuning for additional upgrades and doing custom tuning depending on the location the vehicle will be used in? See, basically what we are looking at is a the product of a very aggressive custom tune on one particular vehicle. So not only are those gains not going to be consistent using that same flash for other cars wherever they are, but it's not even safe or recommended. I'm sure you have all of this thought out, but I am simply expressing concerns others would have as well. We just need more info, any new product especially from a company with a great reputation is going to catch some attention. The price really adds to attention because we would want to know what the advantages are. From the information you've posted so far...there are only disadvantages seen. The way it feels now is if I were to send my ECU in to you (major pain to do in itself plus additional costs) and have you flash it with some tune you got off of a test car, and send it back to me. How is that any better than buying a Cobb and using an Off The Shelf aggressive tune? Except for with the Cobb you can datalog some street pulls, and make adjustments yourself, or go to a Cobb pro-tuner in your area. Or, Pro-Tuning Freaks e-tune. I'm sorry if it comes off as me being offensive, but I assure you I am doing nothing but trying to help and lay out all concerns and questions the majority of this platforms' users would have. Thank you and looking forward to your response, Matt

    I believe it did. Looks like the one they had in the headers video, it also sounded very loud on the downshift. Having a M156 with headers myself, the sound is very close. I doubt there are that many red SLS BS's running around.

    The cobb systems are piggy back units and they do not have as much control as we do and other tuners do that go in to the ECU and tune. We are having to make piggy back units for some of the new mercedes cars do to tuner block on the ECU and they will not make as power as our other ECU's because we can not control as much.

    He's overthinking this whole design thing IMO. The reason for the original design of the M10 cylinder part (they didn't use the whole block, just this part mainly) was so sturdy and overdesigned, was probably due to low production costs/ore prices and cast production limitations. The BMW F1 section never complained about the sturdiness of the bottom end of the M10. They needed the oldest blocks for the F1 engines. There ad to be a lot of miles on the engines, and rumor goes they were peed on a lot by the engineers. There used to be a big pile of the engines behind the development building and everyone was to do their no. 1 there. The acid in urine somehow helped hardening the blocks...

    You're forgetting one important thing here. Qualifying at that time was done in 3 sessions spread over the friday and saturday. There were no engine restrictions in terms of max amount of engines used, so the engines used for qualifying were only meant to last one qualifying session at most. And some (most at the early turbo times) didn't even make that and blew up. These engines had an over 3 Atm boost and unlimited fuel supply so yes, in the end they made just about 1500 hp. For the races the race-engine was highly detuned to last the 300km race distance, and these engines had an output of around 800hp, although that can not be verified But compared to the performance of the NA opponents they must have been around that power level.
