That is right. I just got off of the phone with them and Skunk 2 is making a composite intake manifold for the evo 8. I can't wait until it comes out. It will be this summer and no pricing yet. They are also making a billet throttle body and composite fuel rail.

 

just out of curiosity are all intake manifolds composite? Or what is so good about it? Skunk2 does make some quality stuff, so nice find.

 

Composite as in Carbon Fiber/Fiberglass?

 

I am sure he is referring to a plastic manifold, maybe carbon. The o.e.'s have been doing this for a while, but under boost or even high boost...

 

that would be composite.

 

When i was making toilet dump tubes at lear jet out of .090 fiber glass, quality stuff, it held 15psi to pass inspection......Somthing like vacuum formed/auto claved pre-preg material .150-.200 carbon would hold 30 psi easy. Quite a bit more ime sure....

 

they have been using composite cylinders to hold CNG (compressed natural gas) at well over 1,000 PSI for years now so I don't think 30psi would be any problem assuming there are no defects.

 

^^^ Oh, i forgot about that, arnt those paintball carbon cylinders holding 3000 psi of nitrogen???

 

SVSU built a carbon fibre intake manifold for their turbo'd FSAE car. I believe many race cars use them. If it is properly designed, it should be able to hold as much boost as you can throw at it.

EVOlutionary

 

probably, I was gonna say the cng tanks were rated to 3,000 psi but It has been many years since I worked around those. Obviously a cylinder is a better pressure vessel than an intake manifold, but I don't think there would be any problem holding more boost than you could throw at it with a proper design.

 

lots of porsche guys have them for both n/a and trubo applications

 

Exactly if it is designed right it will hold pressure fine, if you notice most of the time they arent made like a big box, they are rounded and have a lot of thought into the stress an intake manifold is subject too. A nitrous back fire could send a chunk of change out the window though.

 

it should look something like this

 

this is one for a honda it looks nice but over priced

 

Sick!
