GT Motorsports Sets the Bar! 800rwhp 20 PSI
GT Motorsports Sets the Bar! 800rwhp 20 PSI
We are pleased to announce our latest accomplishment, As many of you know we have a 4.24L Z shop car that you have all been anxiously waiting to see what we do with it. Last night I decided to pull a 24 hour shift and begin tuning our beast. The engine had almost 1,000 miles on it and I felt was ready for some dyno time (breaking in the engine properly is VERY important for any built high performance engine!) I started at 12psi (waste gate pressure on APS Extreme kit) and ended the tune SEVERAL hours and countless dyno pulls later at 20 PSI, all the way to dawn 
The last run for the night ( run #43, that's right 43 back to back dyno runs in one night/morning!) yielded our goal of 800rwhp, on 105 octane UNLEADED, on a very conservative tune. As stated before our number one priority is to have our engines LAST! Anyone can make power on a dyno, but not everyone can make it last in the real world. The car was very stable at these power levels and I feel we have more room left to push. As a matter of fact we will be driving the car today to Auto Crave 2007. After a few thousand more miles on the car and some real world condition tests we will be back on the dyno with some C16 and Red bull
, reaching to break the 4 digit mark!(1,000rwhp+ coming soon!)
