I have been reading about the LSX intake from FAST and since I am planning to upgrade my LS1 with SLP's LS6 I was wondering if the extra money for the LSX would be worth it? I have sufficent outake......I need more air intake. Any opinions?

From what I have heard its about 11rwhp or less of a gain from an LS6. Most of the local guys around here (local guys) still stick with their LS6 because its not worth the extra money. Now if you went with a big power adder or something then I would.

agreed...big cubes or a blower and you may benefit from the LSx

however, car craft or some mag did a side by side test of the ls1, ls6, truck intake, lsx and the holley intakes.

the ls6 and the lsx were within 1hp on a 420hp crate motor.

the truck intake was a bit lower but had more torque, and the holley and about a 1hp gain on the stock ls1 :blah:

1hp doesn't warrent a 2x price tag for the LSx in my opinion...not untill you are knee deep in a $10,000 motor to start with.

So I guess I'll just stick with my orginal plan and get the SLP LS6 intake. I need to keep my EGR. Should I keep my stock throttle body or go with a bigger one?

stock is more than addiquate...

if you wanted you could port out your stocker pretty cheap.

there are companies that do ported TBs for $120-200

PM me and i can get you contact info for a guy who will port it for $50 i have pics of mine...great work and inexpensive.

Way overpriced for almost identical LS6 intake gains

so is the SLP one the composite built? or is it the crap aluminum?

the SLP ls6 intake is composite as well...and you can option for it to have the EGR provisions.
