Dyno Results on C16 Race Gas - Viper TT
I sent the car back to Underground Racing to have all the gas maps tuned. They spent about a week tuning each map to make sure all the qwirks are cleaned up.
Keep in mind, all the gains were turned down during these runs because the car kept losing traction on the dyno:
93 octane At 9PSI - 900RWHP, 900RWTQ
100 octane At 13PSI - 1000RWHP, 1000RWTQ
116 (C16) Octane At 17PSI - 1200RWHP, 1120RWTQ.
As far as I know, Undground produced the most HP out of an SRT10 TT. I originally had the car shipped to FL with 93 octane tuning, but after a car wash, my ecu got wet, and since then, ran like **** in 1st and 2nd gear. I sent the car back to Underground , and installed a new VEC II (this time with a water repellant cover,) and had it tuned to the aforementioned octane maps. I am surprised to see how smooth the car is now in 1st and 2nd WITHOUT sputtering, or popping......something I experienced with a soaking wet VEC.
They also installed a Dual Friction clutch, which has a love / hate feel. This clutch can easily withstand the 1200HP however, it either hooks or doesn't. There is no inbetween, and it chirps between each gear. The shifting is a bit notchy, and the clutch has to be 99% depressed for smoother shifting.
I laid on it from 80 to 160 within a few seconds last night :-) before it started raining. This is the fastest car I've been in/driven.

Chordate, Something like that...it had substantially more room / HP to go with, but traction hindering.

Wow Shank, that is sick. Post some more pictures/videos of the car, I doubt anyone here will get enough anytime soon.

A ride in shanks Viper
I took a ride in this animal just before the tuning....It defined the term "neck snapping acceleration". We went from 40 to 120 in a snap of a finger....I was speachless...which is quite a feat if you know me :-)

Shank, will that kind of power spin the wheels inside the tires? That is some serious HP, I remember the old dragster guys had to screw the tire bead to the wheel to keep them from spinning around, they still may be doing this for all I know?
