i drive without my hood... at the track.... lol but then again, I have a cast iron intake manifold....

pretty much nothing likes nitrous backfires.
i used to have a picture where a guy blew his aluminum intake into about 4 pieces from nitrous
|
was it a sheet metal aluminum intake? or a cast/forged aluminum intake?

"Normally" is a relative term...because you just found out about this recently, right? There's been plastic manifolds on LS1s, for instance, since 1998...relatively speaking, plastic intake manifolds aren't a new thing - and they seem to be holding up pretty darn well.
Luckily...an intake manifold doesn't spin real fast or tear down trees -- it just routes air. You could probably make it out of glass if the ride wasn't so jarring. :D

actually, there's been composite (better term instead of plastic lol) intake manifolds on LS1s since 96/97.... (remember, they came on the vettes first)
and actually, ive seen single runner carbon fiber intake manifolds .
check out this W-9 motor....lol

well not completely useless. I have a Remote Control truck that has plastic gears and they worked for a few years. :)

and how much power is getting applied to those gears? not a whole lot compared to using the same gear in a car.

I see. Still you're tensioning and moving things. Intake manifolds just sit there. They offer zero structural support, and they aren't under any real stresses.
Also, bear in mind; not all plastics are created equal. There are some that can repel bullets, and there are some that would break if you farted on it. The plastics they put on engines is high-quality stuff.
|
actually they do suffer under some stresses, vacuum pressure from the motor does put minute stress on it, but its been developed to withstand that. and if you've ever run nitrous or f/i on it, that adds stress, but still, they are some damn good composites.

This has been good information. The engine block is still metal though right?

no, actually they changed it to a carbon fiber design to reduce on weight....
yes its still metal. :drinking: |
