All aboard the fail boat. Honestly plastic manifold.... and wants to run nitrous? looser.

[GoLfMan]

Mk5 GTI's have plastic inlet manifolds

DONT RUN NITROUS FELLAS

[VeeDubs]

dang thats just what i was going to do.

thanks for the warning fellas haha

[Spyda]

Why plastic? It doesn't seem right at all. Cost cutting much?

[jayjay]

so do bora v6s.. are they limited by pressure only? what about high temperatures?

[vagman]

what a tool. running nitrous with a plastic manifold.

[kaneda]

I dont understand whats wrong with running a plastic manifold with nitrous ?
Explain to me what the manifold has to do with it.

[Blitzen]

Nitrous won't do anything in the intake manifold, and its an inert gas, so it is non flamible. I really don't know what the big deal is about plastic inlet manifolds...The new Golf VI's have them, the Festiva XR4 has them, as dose some of the Focus range, including the XR5.

This guy was obviously running a wet nitrous system in the inlet manifold eg nitrous and fuel spraying into manifold... rather than a dry system where only nitrous is going through intake and fuel injection comes via normal injectors either directly in cylinder or just before valve.

Backfire can occur on a dry system but is very unlikely.

Also, many of the ford guys in the usa run composite manifolds with 300hp nitrous shots even.. its only an isssue if there is a backfire and even then would u rather have a blower or turbo go boom or have a plastic manifold just shred safely.
