Probably a beast, but it looks like chit.

Never heard of Griffith Racing in the Viper world. Heffner, ART, and Underground are the best. Hennessey has been doing it for years but his prices are crazy.

side pipes and the numbers on the rear quarters make it shitty

Well, the side pipes would be covered up by the sills (missing in the pictures) and I would think they'd paint over those goofy flames.

that thing is busted looking, but the motor looks like a sweet setup.

The "best" Viper tuner topic has been debated ad nauseum. No doubt Underground has been turning out some very nice TT Vipers and Lambos.

I know Jason and have been to his shop down in Sarasota. I've met David Weaver from ART in Texas. Both were really cool to me even though I was not spending money with them at the time.

I've never met Kevin or K.C., but they certainly have great customer feedback. I know plenty of guys that have had their Vipers and Gallardos go through UR with amazing results. To date I have not read any negative things about their shop or workmanship. Plus, they are in Charlotte so when I do eventually pull the trigger on another Viper or a Gallardo it will probably go to them for a massage.

i would suspect that paint to be left over from a LSR trip or something,
and the front clip is new to fit over the induction.

what's the little pipe by the Griffith logo?
looks like the generator pipe on an RV :)

is it the BOV? i thought you had to reroute the BOV back in behind the MAF, but in front of the turbo, to keep the AFR right, since the MAF had already measured that air?

that pipe is a screamer pipe for the wastegate. just keeps the spent gasses/heat out of the engine compartment.

i would assume that recec would be pointless the car is built for higherboost. the 4psi is a break in setup.

allot of guys are gunning for s.w. in the texas mile... underground being one of them. a few big ford gt guys.. and a handfull of other people.. not to mention some people over seas(dubai) that were at the last texas mile.

as far as hennessy goes i have a very good friend that works with john like side/side... he has some really nice stuff on the fringe. along with a few r35 stuff thats straight bannanas..

Good stuff. I'm trying to go spectate the TM. SW is the man/car to beat. He is a class act by all accounts.

and hear is the art 6sec drag car being built. i am not sure who brought up art and turbo vipers but this one seems to fit the bill.. this is an outlaw class car byet he way not a standing mile car.

Yep, that's Ray Hoffman's car at ART. It is going to be a wild one. Ray has more toys than the law should allow. Super nice guy. His Heffner Bumblebee TT FGT won a Car & Driver 0-200-0 shootout a few years ago.
