That is about the best way to describe my Viper GTS since getting it back from Underground Racing in Charlotte. As most of you know Snor (Sean) and I had decided to both go with UGR's Paxton builds after seeing the "900 rwhp" thread Kevin started. I won't speak for Sean, but I know now that I could have NOT made a better choice. This car is simply amazing now.
After 2 torturous days of seeing the cars stacked in my garage due to the weather outside I was ready to go all "JD" on everybody Other than the obvious thing of not driving it at this point it was killing me not being able to pop open the hood and check out the goodies.
Today was "the day" Weather a solid 50 degrees, sunny skies, and not a cloud in sight. I pulled both cars out and gave them a very brief wipe down from being unloaded a couple days prior in the rain Popped open the hood and it was like God was speaking to me as the polished blower and fuel rail sparkled in the sunlight. These pictures do it NO true justice.
Now for the DRIVE. Sean pulled up to this sight awaiting him at the foot of my drive. The smile on his face was like a kid on prom night being told by his date to disrobe.
The cars had been pre-warmed by yours truly and ready to go. A quick once over his car and Sean said, "So, you ready to take these fuckers out or what?"
We only went a short 10 or so miles terrorizing the back roards near my home and leaving black lines of a tell tale sign of where we had came from Surprisingly the invos I have are what I was told, a great tire. They held the power well until the upper echelon of the RPM spectrum was reached. At that point the only thing that happened was the appearence of massive black rubber being laid to the asphalt as the boost ramped in something fearful. It was in a word, NASTY.
No video yet boys but soon I promise. I have big plans for this car.
THE NUMBERS.Kevin and his shop blew me away with everything they did. They probably care almost TOO much about the customer if that is possible. We spoke daily about the progress usually once or twice a day. These guys called me on Sundays making dyno pulls to shoot the shit. His work ethic is second to none really. Ok, enough...
As you can tell from the graph the car made corrected numbers of 915 rwhp. with a torque (although not present) assumed to have been in the 900 even range. KC was having issues getting a good tach signal to stay constant so rather waste time I told them to fuck it. I can always get the car redyno'd at a later time. I was suffering some serious viper withdraw. The timing and methanol are set VERY CONSERVATIVELY. The car had other pulls made with some more aggressive timing but I wanted it backed down to where I knew I wouldn't be inviting any issues. By doing so I may have sacrificed 30 or so RWHP but 915 is nothing to sneeze at I had originally sent the car to Kevin planning to do just the AEM, Paxton, meth and that was it. Somewhere down the road, my asshole friend Sean had decided to go with heads, and when Kevin told me that I matched the bet as well, doing heads and T7D rockers. Snors car made about 5-10 rwhp more than me using his 3.55 gears which Kevin put back to stock after the pull. Time prevented Seans from redyno'g using the 3.07's due to Gary Almond showing up and under a tight deadline for other pickups out west. Snors car has headers and mine is still running the factory CAST manifolds which really did decent considering the minimal spread in rwhp between the two rides. Sean also chose a JM stage 3 cnc head when Kevin got me a superb deal on a set of fox lake heads which had some additional head porting done on. They worked great too.
I wanted to again thank Kevin, and his guys for the amazing vehicle they put together for me and I can't say much more than that. Underground Customer for life.
BTW, KC is a fucking AEM tuning genius. Look at the steadiness of the A/F and the HP curve. NO DIPS whatsoever. And the best part is looking at the smoothing the graph was set to. That is how perfect he makes these things. Stock drivability under part throttle and warp speed under the boost.
Congrats. I always wondered how good the stock headers (which I believe are hydroformed) would hold up in a supercharged application...now I know. Apparently those Fox Lake heads must be pretty decent! What kind of boost did you end up seeing with the improved head flow on the heads?

Congrats Josh and Sean. You are going to really enjoy your new toys.
In winter traction is always slim to none so be extra careful. I feel the difference even down here when it drops down to a frigid 50 degrees in the evening.
Very interesting to know that the sotck manifolds can flow well enough at those power levels.
And Absolutely Amazing that you're getting any traction at all at the temps we're at now! Have Fun w/ them! Can't wait for some real-world MPH and ET's!!!
If I'm ever in Jersey with my '06 coupe and see two red GTS cars coming up behind me, rather than *trying*, I think I'll just smile and wave you on by. Don't need that kind of embarrasment.
cars look great cant wait to see some mid 9s soon. i always thought the dyno #s are lower with gears and you will have higher numbers with the 3.07 so snor could have 10-15 more that would account for the missing headers hp, maybe im wrong. have you guys raced yet and how much boost were the hp #s at?
