640 rwhp 2010 gt500
One of our clients brought us his brand new 2010 GT500 for some major upgrades. The new 2010 GT500 is a beast from the factory as it is. Rated @ 540 hp at the crank, the new GT500 was able to lay down 483 hp @ the wheels bone stock! For most people that would be enough.......well, most people. Some of us just have the bug and always want more!
Plans for this build are: Whipple 2.9 supercharger upgrade C&R Heat exchanger upgrade L&M Twin 66mm Throttle Body Fore Precision Fuel Rails JLT Carbon Fiber Intake Tube Corsa Extreme Axle back exhaust FRPP Suspension Engine Compartment dress up parts from Project 321 Last edited by Brady@PPC; 02-23-2010 at 09:55 AM.

The next step was to get the car on the lift and remove the front bumper to expose the stock heat exchanger.
  Once the stock heat exchanger was out, we could compare it to the new C&R unit. The C&R unit is much larger, holds an extra 2 qts of fluid, has dual 9" cooling fans, and is 100% made in the USA! That is a combo that is hard to beat.  The C&R heat exchanger is the exact same heat exchanger used in the Shelby Supersnake upgrade. The only difference is the C&R logo on the front versus the Shelby logo(only available through Shelby).  The dual 9" suction fans are triggered from the intercooler pump. Anytime the intercooler pump is running, the fans are running. The end result is a major decrease in intake air temperatures entering the motor. The short version is "cooler air, more reliable power".

The next step was to get the factory supercharger off the car. "Off with the old and in with the new" definitely applies here!
Stock supercharger removed  The stock supercharger is a 2.1L Roots type supercharger. The new Whipple is a 2.9L Twin Screw supercharger. The Twin Screw is much more efficient at higher boost levels than the roots. The larger size of the supercharger is also very helpful in this case.

Once the new supercharger was bolted on, the new L&M throttle body could be attached. Another item made in the USA.
 The L&M is a very nice unit and quite a bit larger than stock. This particular unit came in the optional black anodized finish.   At the same time as the throttle body install, a cooler heat range spark plug was isntalled, and the stock coil covers were swapped for a much nicer set of black anodized billet aluminum covers from Project 321.

The final piece of the puzzle under the hood was a carbon fiber JLT intake tube. The end result is an install that looks clean and like it could have came from the factory.
  With the Corsa exhaust installed out back, it was time to head back to the dyno to begin tuning. Last edited by Brady@PPC; 02-21-2010 at 01:14 PM.

The C&R Heat Exchanger is worth its weight in gold. Average post blower temp at 6200 rpm was 115-118*. Obviously that will be different on hotter day but we have it set up to pull timing for safetly as post blower iats rise.

A quick soundclip of the Corsa Extreme exhaust. The best part about it is that there is absolutely zero drone inside the car. Sounds mean outside but is nice and mild on the inside of the car.
