Ls1 intake manafold

I was watching horse power tv again and saw a part where the guys said that the stock intake manafold can not handle boost or nitrous is this true?? they said it was a "composite intake" you can scroll down and check it out here >>> http://www.horsepowertv.com/ingear.aspx

depends..if u wanna push it and go 4 it..it might work a few times...just don't get angry when u have to replace it.

PLENTY of people are using the LS1 intake with their Blown and Sprayed applications. Unless you have a backfire, they are good to go. 2001-2002 LS1's recieved the LS6 intake, which is still made from a composite.

the problem that they are talking about is on the back of the intake manifold. on earlier dsigns there is a Manifold absolute pressure sensor located in a big round hole in the back, when that was relocated they didnt change the manifold, they just put a big plastic plug in the hole left by the sensor. if you run nitrous or boost, and you backfire, or are running alot of boost, that plug will pop out, and all of a sudden you have a major vacume leak. i have seen people epoxy them into place and never have a problem.

if you cant duck it, f*ck it...

so its not that big of a problem???

i dont think so, but i dont know exactly what their reason for thinking it was unsafe was. they might know something i dont.

well all they said was it could not handle the stress of nx or boost your explanation is good enough for me but can you upgrade the manafold for more horse power???

I don't see why that plug would cause a problem in a nitrous car. I mean if you get a good nitrous backfire metal or plastic the intake is probably not going to survive. If anything the plug popping out might give it a release.

Also that that plug might cause problems in high boost cars. It has the same effect on the TT SBF with high boost the PCV in the back of the manifold sometimes will pop out.

I think they said the composite intake couldn't take it just for the same reasons they say that about the 4.6 Mustangs composite intake. It's just new and unfamiliar... I mean it seems to the common person metal is stronger than plastic.

My father is a plastics engineer and he was telling me in the early 90's the amazing things that could be done with plastic composites and there would be plastic intake manifolds on many cars. He showed me an article of a 4-stroke motor made completely of plastic composites the block, pistons, etc.., Give it a few more years and plastic intakes will overtake metal in OEM and aftermarket systems cause there upsides are huge.

wow thats something almost scary in a way

the new LS2 has a revamped composite intake. apparently they improved the plastic welding process and the thing is lighter, twice as strong, and flows better. plastics may be the way of the future...

Holy Cow. :eek: thanks for the update on how this technology is never going to stop.

even the exhaust pipes and headers???

My friend runs a 125 shot of nitrous in his 99 TA with out a problem.
