99 z28 vs 03 cobra
#21
Well he mentions that he shut down at 110, so he somewhat ovoided his trap speed and seems to me that he lost. Unless im readin it wrong???

You guys are retarded or something I swear to god. When I first got my car it had a catback and a tune which wouldn't give me quite as big of a gain as an intake and a tune on a Cobra. I was beating full-bolt on LS1's by 1-2 cars to 120 all day every day.

The only thing that i dont have is and electric water pump and an ud pulley. Like i said i had an intake which is an ls6 intake for the record. I also said that his car was pulling me on the big end but not as bad as i expected it to do so. His tune was a hand held tuner by the way

my 99' dynoed 330hp/345trq with nothing but a magnaflow catback and whisper lid. every cars diffrent. i know for a fact that full exhaust ls1's can run with intake/exh. 03/04 cobras. done it a few times my self before the cam. and if you guys didnt notice. he didnt say it was dead even. he said he got a small jump on the guy and that the guy was pulling away when they let off.

What are your track times?
OP, The SLP UD pully was worth 14rwhp & 12rwtq on my car.

Did the Cobra have a smaller pulley on it? If it didn't I could see the outcome going the way it did if the LS1 driver was a bit quicker with the shifts. Crazy that an LS1 owner actually posted a race where they lose(happens once every 120 threads).
