http://www.youtube.com/watch?v=3Un96kGQFS0Here's what Lethal Perfomance's build consists of:
We decided to pull the stock 2010 GT500 motor and replace it with an all aluminum built race motor by Al Papitto. From custom cams and pistons to billet I-beam rods this motor was built to make some serious power. It didn't stop there as there was extensive head work done by Chris @ Champion Racing Heads. We topped the motor off with the massive 4.0L Whipple supercharger with the custom Super Cobra Jet Crusher inlet and Whipple's Monoblade throttle body and CAI with 123mm MAF. 80lb Injectors and a Triple Walbro return style system featuring Fore Precision Works fuel hat, fuel rails , Aermotive Pro-Series regulator and filter supplies all the fuel we need at the moment.
For the exhaust we're running American Racing Headers 1-7/8" Longtubes with a 3" Offroad X-pipe (Thanks Nick) and the 3" Magnaflow Catback with Magnapack Mufflers. The Magnaflow kit has been modified so that there's no neck down in the system. It's 3" all the way.
The cooling system consists of the Revan Racing/C&R Dual Pass Heat Exchanger with Dual Puller Fans, Lethal Performance Intercooler Pump Upgrade kit featuring a 55gpm waterpump, Reische Performance 170deg thermostat and a Moroso Intercooler Reservoir.
The drivetrain consists of the stock TR6060 transmission, Mcleod RXT twin disc clutch kit, Mcleod Steel flywheel, Steeda Tri-Ax shifter and a DSS 3.5" aluminum driveshaft.
Our front suspension consists of a BMR Fabrication lowered K-member, BMR adjustable A-Arms, BMR K-member support brace, QA1 Adjustable struts and a QA1 front coil over kit.
Our rear suspension consists of Steeda Upper and Lower control arms with Upper mount and lower relocation brackets, Steeda Panhard Rod and Brace, Steeda Torque box brace, QA1 adjustable shocks and Eibach sportline rear springs.
