I've been looking through here for some time for some answers for my 99 Z/28. I have not been able to find them, so forgive me if these are a repost. Point me in the right direction if they are

Which is better price and performance: LS6 intake or the FAST LSX? I notice alot of you have the LS6, and that was going to be my choice. I just wanted to know whats different about the LSX and if its worth it.

Ive been looking at buying the SLP cold air kit, but after seeing multiple threads leaning away from it, I came upon the SSRA. Very neat and the next thing I'm gonna get when I get the money. SSRA sounds like a good start, but is there anything else that can be done to help the LS1 breath better? I notice the SLP kit its installed right in front of the radiator, and I assume thats gonna rob the engine. Also, what LTs are recommended these days?

Thanks

 

it depends all on your budget... there are budget headers ie pacesetter, flowtech, and jet-hot

there are non budget headers = qtp, krooks, and flp

as for the ssra yeah it is a good idea gets you some pressure at 75+ mph

and as for the ls6 intake... unless you are going to be doing a huge h/c set up it isnt worth it... just stick with the ls6

the difference is 12 mm... the fast lsx intake is 90 mm where as the ls6 is 78mm... the lsx is way expensive so just buy a 300 dollar used ls6

 

Budget isn't a problem for me, just takes time to get the money.

How much is the difference between an LS1 intake and the LS6 performance and price?

 

i world of difference... the ls6 simply has better runners and can hold a better volume air... it makes more power across the powerband rather than peak power... it is a must for all bolton cars and esp. cammed cars...

 

Right on. Anything else to add with the SSRA, or is it all the engine needs?

 

pretty much an ideal air intake system for the camaro ss is ssra, intake lid, bellow, descreened maf, and then a ls6 manifold... is all you need and you will be set for a mild cam setup

 

I'm not a big fan of descreening the maf. The screen is intended to smooth the air flow so the maf can get accurate readings of the incoming air. The stock maf flows plenty good as it is.

 

agreed....and the bellows is a 99.9% visual mod. and i've heard of more than one person cracking thier lid or air box due to engine flex and the bellow not having enough give in it to absorb the flex.

you don't list any mods...so i'm gonna assume you have none.

you're on the right track with the SSRA, but you'll also need a lid to compliment the added incoming air. they are a dyno proven (many times) 7-10rwhp.

on stock and bolt on cars, the ls6 intake is also a dyno proven 7-10rwhp mod. on cammed cars some claim to have gotten as much as 20hp. but i'm not 100% sold on that. $250-300 for a used ls6 intake is much better than the $800 for the LSx intake. several tests have shown that the LSx is only beneficial (relative to the 3x cost) on boosted, big cube or big heads/cam setups. one test i saw of the ls6 and lsx showed that on a 400hp crate motor the LSx only gained 1hp over the other intake. although it showed promise in the upper rpm and would probably have performed better had the engine spun above the 6400rpm limit in the test. if yo're looking for EVERY bolt on possible to make power, the LSx is a good choice. but for the average street car, garage mechanic...stick with the budget minded and still good performing LS6 intake.

going back to whether you have mods or not. getting the air in is good. then you have to get the exhaust out. either get a decent catback or install a cutout on the stock system. do some research on catbacks...there are plenty of threads. popular budget systems that flow well are Hooker, SLP loudmouth I & II, magnaflow, TSP rumber. check out www.ls1sounds.com for some clips of how they sound.

 

Lots of info, thanks guys!

Yeah, forgot to mentioned im stock. I just orderded a MagnaFlow Cat-Backs kit last week, and should be here today (what a nice Valentine gift...to my girl lol). Induction then headers will follow.

One last question so that this thread doesnt become longer than it needs to be: where can I get and LS6 intake?

 

watch the for sale forum...

also try over on www.ls1tech.com for them. maybe some vette forums.

and obviously Ebay.

just make sure you get a pic of the bottom of the intake, to confirm that it is INDEED an ls6, not an ls1 off of a vette.

i beleive the ls6 intake has a flat bottom, the ls1 has some curves in it. just because it doesn't have the EGR hole doesn't mean it's an ls6.

 

Here, check this out for more info: http://www.ls1howto.com/index.php?article=5

It even has side by side pics of the two so you know what to look for. This car has headers and it's cammed and i'm not sure what else, but they pulled 24rwhp out of it.

 

Go with the SSRA. You'll love it.
