Ls6, fast, edelbrock ect...

I'm looking for something that will make power up past 6krpms... and that will still make power in a 6.0 with the same setup. I figured SOMEONE has to have tested them before and after????

I think Greg and others are saying what I did in a better manner...and I did not mention the LS2 as it's obviously different than any F-car intake. But remember, we were talking about the LS6 (for a while)....my point was that ALL 5.7 car engines had the LS6 intake at some point (2001-2002?).

correct starting in 2001.

97 to 00 had the ls1 intake

01 and 02 had the LS6 intake

Ls6 outflows the Ls2

Ls2 is similar to the ls1 intake even tho it has a 90mm opening and on paper it looks to be better then the Ls6 it actually isnt

IMHO there are only 2 intakes out there worth any money or time installing....these are the Ls6 and the Fast90 [ported 90 is tits]

I run the Ls2 cause im boosted and wanted the bling factor of reusing my 90mm tb and allowng myself to use 4" tubing. If i was building a turbo Fbody i would just use the LS6 intake


Now for what you want Jeff, if you cant afford the Fast 90 then Port your 78mm tb then run the Ls6 intake

to run the car intake you just need to take the idler pulley from on the Alt bracket and side it over about 3" to the other bolt that is there now. this will allow you to run the car intake with still using the truck accesories.

What about the vic Jr. ?

i dont like them for most applications. ppl run them for cool factor and arent using them properly. most lose power using this style intake since the cam they have isnt meant for that style of air flow. something solid roller and big rpms i would consider this style intake along with a 4500 fast TB besides that the fast 90 is best intake IMHO for majority of ppl

There is a article on the fast 92 in the feb 09 super chevy on a 5.3 out of a 02 tahoe and they gained 34 horsepower on dyno. Overall with a cam, heads, headers, fast 92 and tuning the 5.3 put down 475 horses and 441 torque.

I think the fbody/ybody LS1 engines had one style from 97 to mid year 2001 and then they switched all the LS1/LS6 engines to the flat floor LS6 intake. LS2 intake is totally different, many report losing HP running the LS2 intake on a 5.7L and smaller engine since it was designed for use on a 6L engine.

Yes, yes. Good call Gregory.

Well, then that would be the LS6.

Repetition of statement. George is absolutely correct.
The LS2 intake would work better with a truck (preferably of 6.0L in displacement) due to the intake runner design to make more torque versus the LS6. But if you want absolute power in the upper RPM range, go with LS6/FAST 90.

Also, if you plan on spending the time of money into doing this type of intake work, might as well go ahead and get some head work done. Is all of this going on the 4.8L?
