it has already been over month since i got my TT viper from UGR. I always wanted to put the car on the dyno to see what it makes on pump gas and make some tuning changes my environment here on northern Virginia compare to NC. Today weather was perfect and friend of mine introduced me to Frank Smith, who ended up tuning my car today. We took my car to shop called funktion tune in sterling virginia, which happens to be only shop with dyno dynamics dyno. Frank fine tuned the cold start and dialed in the driveability. End of the day on pump gas with methanol injection car make 957rwhp @12PSI on loading dyno. This was done by back to back pulls with engine running for about two hours on the dyno. If we cooled the car down I'm sure it would of made 1000rwhp but power was never the problem for this car. underground built one fast TT viper and thanks to Frank Smith for dialing in the car for my northern virginia environment.

I have twin T78's on mine. Isn't it just a fun car to drive? I had mine out yesterday, enjoying this beautiful weather, and these UGR cars are a blast.
What kind of head work do you have on your car? Awsome numbers.... That's how I like to see numbers. The way the car is driven all the time with daily heat on it. REAL time. Thanks.

Looks like you bought Jeff's car, not a bad investment for a few K less then an 08 car and more then double the power.
Have fun and dont let the boost bite you...
957 hp should be able to put your adrenal glands into overdrive, have fun
we could of tuned it for more power but it was already too fast for streets. I'm thinking about tuning my car on E85, which should be able to run 20+ psi. There are plans of bringing few more E85 stations where i live and I'll wait until that happens. So more c116, E85 is race gas on pump for $2.50. Much cheaper and easier to get than c16.
