5.7l Gto

[fentress24]

friend has a 5.7L GTO with a cat back and i have a 2005 Srt-4 with tb no cat, and a kinetic wga 18/15. well we did a few runs and its pretty even from a roll until about fourth. In fourth i was expecting to pull about half a car beacause our fourth gear is so long, but he pulled half a car. all he has is a cat-back. i was alittle confused, i knew it would be close, but thought it would be the other way around. im asking because im starting to think i might be pulling timing. thanks

at 18 psi you more than likely are... lower it to 17 and you should see a difference.
with those mods thats just about where both cars should be running.

alright thanks just wanted to check, also i was speed shifting and almost positive he was not, couldn't hear over my car.

You thought you would pull on an LSX car at top end? Lolz.

map clamp, more boost and some meth/water injection would do it.

ive seen srt 4 on fully bolt ons take down 6.0 gto's but its true about thinking of taking down an lsxcar at top en. i have a friend with a srt 4 taking down c6's till top of 3rd when the c6 obviously pulls a little

Most of the LS1 Goats run mid to higher 13's and trap a drop less then the fbodies...I have seen a few dip into the lower 13's w/ a good driver

[fentress24]

thanks guys i obviously didnt know too much about what the goats ran. thanks for the feedback. it was a good race with a good friend of mine

Most LS1 GTO's run 13.8 to 14.2 at the track, basically same as the SRT-4 with a good driver. I've never seen one run under a 13.7 stock, ever.
