GRP or plastic VS heat
dmottaway - 14/9/06 at 01:26 PM

will GRP or Carbon Fiber withstand the heat if used for an intake manifold?

Might be easier to use than aluminum for my GSXR TB's on a 4age head.

any ideas?

Should do - it works ok on a lot of modern cars. They use injection moulded polymers, typically with a glass filler for stability & strength. It'll be a complex tool if you intend to make a 1/2 decent job

Hm...wouldn't use GRP post-injector even with epoxy resin.

CF - probably ok?

Can't believe it's that hard to get 4 pipes welded to a flange....

See my post on the other thread of the same name.

Have a lookunder the bonnet of any modern professional racecar, and quite a number of production cars.

Plastics and composite intakes by the dozen.

Aluminium will be quicker and cheaper though. No plugs and moulds to make.

Cheers,
