At over 2,700 feet above sea level in the mountains of North Georgia, a private airport appropriately named Heavens Landing hosted the September 2015 Georgia WannaGOFAST event. This weekend would mark the first performance outing for our Gen V Viper TA Twin Turbo. It passed the dyno test putting down 1,103whp at 10psi on pump fuel back in August, and it passed the street driving test by logging over 800 miles of ‘spirited’ daily driving, so now it was time to turn the boost up and go for it.
As we prepped our Viper the sun began to appear from behind the mountains warming the runway. With almost no humidity in the air and a high of 75°, you couldn’t ask for a better day to race. We got the car tech’ed and lined up to make a shake down pass, low boost (5psi), no launch and full traction control. Chris did a quick burnout to heat up the tires and staged the car. When the lights dropped Chris rolled out a bit, then got into it crossing the finish line well into 5th gear at over 161MPH, not bad for the first run but we knew it would go much faster considering we had another 5psi to play with.
After giving the Viper a quick check over to make sure everything was still tight and secure we staged the car for another pass. Boost was increased to 7.25psi and traction control reduced. Unfortunately right after Chris launched, the MoTeC started cutting power indicating something was wrong, ending a very promising day.
When we got the Viper back to the shop our suspicions were confirmed a wastegate diaphragm had come loose and the MoTeC was triggering its fail-safes to prevent the car from over boosting. A very minor, freak issue….But hey, that’s racing! The ARD shop Viper will be back at the track very soon!
