TVS 03 Cobra vs 2.9 Whipple 03 Cobra
- Thread starter intermatic
- Start date
I peaked at 19.6#s (stock exhaust manifolds).
From what I gathered, he has an O/R x-pipe and catback. I think his only power mods are the TVS w/ GT500 t/b and a CAI. Suspension-wise, he said he had the full FTBR IRS kit. He was also running slicks. I was running 315 R888s. Temperature-wise, it was in the lower 60s. I had a little be of spin in 2nd, but not too much really.
I believe he's on this forum, not sure how often he goes on tho. Hopefully he can chime in with his mods if I didn't get them all.
Tight race!!! Nice video.
Yeah, tight race. You both have nice rides! :rockon:
They were super tight! In the second run we shifted into 4th at the exact same time..sounded a little funny.
Thanks man.
I was very curious to see how my car would match up. I wanted the TVS badly when I was in the market, but didn't want to risk running into a headache with passing emissions..especially up in NY where it's as strict as it is. I asked the guy I ran about it and he said he was able to pass, so maybe it wouldn't have been as bad as I imagined.
Thank you!
I would throw all my money at my car until I could beat him.
That would drive me nuts!:bash:

Im curious to see what your car puts down on a dyno jet. The boost is OK. Not the optimal boost for a 2.9. The combo can be a bit better. Big blower, cams, but its on stock manifolds and low boost.

i raced my buddy with a 2.3 whipple and i have a 2.9 whipple. same setups same boost (22ish) same tuner only difference is his timing is 22-23* mine is 18* (power should be similar due to that) his was a little more snappy on the initial hit after that i think the 2.9 had more in it. i think that the larger 2.9 rotor pack takes just a little more to turn and get going. i wont say lag at all but the 2.3 blowers are lighter and will be easier to spin. if you get the boost and timing on that up in the 22-23 range on both respectively thatll make a HUGE difference.
thanks for sharing the vid

Lol, well I didn't expect a very different outcome honestly. I know the TVS is right on the 2.9's level on pump gas. I'm curious to see how our dyno graphs compare. I had minor spinning in 2nd, which may have attributed to him jumping out in 2nd. But then again, maybe I'm just looking for excuses lol.
Once the IRS gets some love with the FTBR kit this winter, I'll waste even more money and finally make the jump to E85..I'd like to do a lower and upper and spin the piss out it so I'm sitting around 25#s. At that point the R888s definitely won't cut it! Hopefully next spring if money permits.
Yea, I have the comp cam stage 3's. Unfortunately I have no idea how much power they yielded me over the stock cams since I did all my power mods at once.
I'm sure the gains were pretty minimal..I mainly wanted my car to have that lopey grunt to it.

Man nice close runs! Crank that boost up and put some race fuel in the tank and let her eat!
One of the better night videos I've seen in awhile. Nice job OP!
thanks, yea i can't wait til I do..then the 2.9 will be happy
thanks!
on a dynojet breaking into the 600s would be no problem
Very weak for a 2.9..... our 2.9 cars up here in Denver are making high 600's on pump gas. I wouldn't be very happy with my tuner if I was making sub 600's on that blower.
lol my car certainly isn't weak..glad you like your dyno numbers guy
