this has really baffled me, i mean i'll agree that the LS1 has got to be one of the greatest if not the greatest motor GM has ever built, but why would they design an intake to choke it i dont understand.

i mean the R&D of the LS1 has advanced extremely fast, i mean i remember when the hot ticket was the 382 stroker and now you've got people with 422 strokers. Big time improvement and technology if you ask me.

Now you've got these high hp'd stroker and big inch motors topped off by these little intakes. I mean the hp gain would be incredible by some of these big inch strokers with a intake style like a super victor and we know they fit with a cowl hood because that many have used in other carbed 4th gens.

Now i'm not saying to turn the LS1 into a carb, i'm just saying a converted intake like it.

So why hasn't anyone designed something like this yet?

I'm no expert but I beleve I read the intake on these cars are very good flowing. I think people are running these 600hp motors and the intake is still not a restriction. So unless you are planing on going WAY big I think the intake isn't important.

actualy there are a couple of intakes out there that are sheet aluminum, but they are psychoticly high priced, like 3500 dollars

True, but if you look at some of those big hp motors look at the dyno graphs and watch how sharply those power curves fall due to the intake not being able to keep on breathing. That means there is a restriction. I mean, ****, Judson and his SAM orange SS had to design the cam/compression around the not so flowing intake to get it to run those times. In my opinion, a carb style intake could make better gains in upper rpm horsepower for those big inch strokers

HP-GURU

Stock intake looks to nose off hard around 450rwhp with each 10rwhp after this point being increasingly hard to gain.

Its really clear when you look on the dyno graphs.

Its not all about the flow of the intake either, the 15" length resonance tunes to a certain powerband on a 346 and will resonance tune to about 500 less rpm on a 408...

Something like our big SAM engine could probably use more intake but the LS6 is very good. I'd stay with it up to 500 RWHP. MAybe the holley aluminum one will prove to be somewhat better with some development.

Oregon LS1

I dunno if you guys noticed, but Judson at SAM has a prototype intake that was made in 1993 during R&D at GM. It is constructed out of alluminum, and he cut the bottom out of it, made the thing into swiss cheese on the inside, then welded it back together....It has the same basic shape as the composite intake, but it is metal, and has much bigger entrances on the runners like ram horns or velocity stacks. He tried running the sheet metal intake similar to Velocity's, and the thing fell on its face!!!

if you noticed the SEMA show had a 2-piece cast aluminum aftermarket LS1 manifold with a removable bottom to allow for an arbitrary degree of porting! <img src="gr_eek2.gif" border="0">

These manifolds r in no way restrictive! U just need an unrestricted ca$h flow! <img src="gr_images/icons/wink.gif" border="0"> www.nitrouswarehouse.com <img src="graemlins/fluffy.gif" border="0" alt="[Fluffy]" />

We did have that intake but lately switched to the new LS6 intake. Judson had the LS6 intake at the shootout as well. We've tried a few box type manifolds or spyders with mixed results. So far they've only helped at the very top or so a little but Jud has had some others to try as well. When the big orange car gets out to HRP next time I'm sure someone will post if these intakes go faster at least in a 1/4 mile.
