Just have my 2011 GT500 first time dyno tune by Justin from VMP tuning (Justin and his family and BJ are here for the Woodward dream cruise – good to see you guys again in Metro Detroit).
Ambient temperature is ~ 90 – 91*F and humidly is about 65%. Also, there is NOT FAN in front of the radiator during dyno as you can see in the below picture and I am using 93 octane pump gas so it would reflect the real result during a hot summer day.
1[SUP]st[/SUP] pull – 711 RWHP & 708 RW Torque (Ft-lb)
After some twist
Final number – 719 RWHP & 717 RW Torque (Ft-lb)
Quite happy :beer: with the results consider my GT500 is a 2011 model year. If
it’s a 2013/14 GT500 the result would be at least 760 RWHP (due to 0.4L bigger
displacement, 0.6 higher compression ratio, and more duration and higher lift
camshaft). I still have few tricks have not done on my car yet which should
give me another ~30RWHP. My goal is to have a 750RWHP on pump gas with a TVS supercharger.
My mod lists are listed as follow. Also, the motor is totally stock.
• TRUE 136mm ID CAI tube - custom design and made piece
• VMP 70mm twin bore throttle body (bore out from 67mm to 70mm)
• VMP Gen II TVS with 2.4" pulley
• ID 1000cc fuel injector with BPS billet fuel rail
• VMP Fuel Pump Booster
• ARH 1-7/8 long tube header with O/R H pipe & Corsa muffler - this combo is LOUD at WOT
• VMP dual fan heat exchanger
• Reische 170* degree thermostat
• SP-471 spark plug gap at 0.035” – full time 20 volt ignition without spark blow-out
