LS1 edit ?

[98zboy]

I have a friend that talks crap because he had a 99 z28 that he says is faster than my 98 z28. He says his was a ls1 edit that had 415 hp and ran a 8.6 1/8 mi. and 0-60 in 3.9 sec. has anyone heard of this or is he full of it.

I don't know what mods he has, but my stock 99 SS dynoed at 300rwhp, so that makes it about 350+ at the flywheel. So with a few mods and tuning he could be at 415hp easy. Since my dyno, I have done the free ram air mod, TB bypass, installed SLP Loud Mouth and SLP "Y" pipe and SLP lid and smooth bellow. I have not had it dynoed again, but I should be around that without having it tuned. The LS1 is an awsome motor.

his car was stock

Then I doubt he has 415hp.

thats what i said to him

Yeah all LS1 edit does is give you more flexibility to tune your cars PCM. No way that you can gain 65+ hp by tuning alone on a stock car. He is full of it. It is possible that he ran a 8.6 18th though. My car ran a 8.7 bone stock with some tire spin. If he had sticky tires its very possible he ran that fast. Although I dont see him at a 3.9 0-60 time.

my 98 z ran a 9.1 1/8th and i just figured that his should run about the same, but i kinda believed that part, just not the 415 hp and the 3.9 0-60.b/c if i am not mistaken a mclaren only runs like a 3.2 0-60.
