T/A LS1 vs. 01 LS1 ZO6

[GottaHaveLS1]

What is different between the drivetrain or computer tuning of a 305 HP 99 Trans Am and the 385 HP 01 ZO6? They both use the LS1 engine but i've heard that the intake manifolds are different? What do you guys know?

[Zboner]

cause the ZO6 came with the LS6

[GottaHaveLS1]

Ok, that makes sense. So what makes the difference between the LS1 F body's and the LS1 Corvettes?

[Zboner]

they vetts have better induction and exhaust and thats it really they make about the same HP.

lets see here ZO6 had an ls6 intake, ls6 cam, ls6 heads...the 99 car has an ls1 intake, ls1 dinky cam & ls1 heads...the ZO6 usually dynos about 50 rwhp higher.

Your falicy is that the Z06 Corvette has the LS6 engine,,, not the LS1 engine.

huh? that statement makes no sense to me...fallacy means mistake or false assumption...so "your mistake is that the Z06 Corvette has the LS6 engine,,,not the ls1 engine." nobody ever actually alluded to that point. So nobody made that mistake. I happened to point out that the ZO6 has ls6 heads, cam, intake...i forgot to mention the block as well if that was your point *shrug*

ls6 had a higher c/r too i beileve, as well as better flowing stock exhaust, better flowing heads, bigger cam, etc

[Doc99SS]

foff667: read the original post, carefully.

The whole point is that he is comparing an LS1 engine in a TA with an ls6 engine, but he writes that both cars have an LS1 engine, so why is the Z06 Corvette so much faster.

As you pointed out, the two engines are not the same at all, big difference, as Chevy wanted it to be.

And yes, I cant spell falicy.

LS1 Heads provide 10:1
LS6 heads provide 10.5:1

i thought the zo6's had the lsx intake or maybe its six not sure

[MadSeason]

LS6 intake for the Zo6 was also on 2001 and 2002 fbodys

[GottaHaveLS1]

I thought the ls2 intake was on the 01 and 02 f body's. but maybe i'm wrong. the 01 and 02 f body's only have 5 more HP than the previous 4th gens. Wouldnt an LS6 intake add more horse than that? Like 15 hp? I jus thought i heard it was the ls2.

[MadSeason]

ls2 didnt even come out until the 2005 model gto and corvette

[Danger731]

02 = ls6 intake

[Vettish]

ls2 intake manifold uses a 90mm throttle body if i herd correctly. Factory ls1 and ls6 throttle body is 78mm.

75

[MadSeason]

the MAF is 75, TB is 78

[GottaHaveLS1]

Shows what i know...

You are quoting factory HP numbers. The LS6 intake is generally worth more than 5 HP. That in conjunction with better camshaft and better flowing exhaust manifolds is why LS1's are under-rated, at least in the f-body.
