Just curious has anyone here considered the benefits of using a manifold insulator or spacer to bring down intake temps, and keep things cool?



This a common bolt on, in piston engines, and I think it might work well with our high temp rotaries.... I looked around but didn't see that anyone made these. However I do have a friend that custom makes them for other cars. He could easily whip one up off a design of a stock gasket, with thicker more resistant materials.



Any thoughts?

Yeah I have seen them on ebay.com for like $20. they are made out of some thick reusable plastic. That insulates the engine from the intake. Hell cant go wrong for $20!! even if it did not and much performance it would pay for its self in gaskets since its reuable.. https://www.nopistons.com/forums/pub...IR#>/bigok.gif

I've actually seen dyno's on these, they work well on piston engines, good for about a 4% gain from what I've seen. My bro doesn't use rubber he uses a heat resistant plastic, I'll look up the exact compound he uses.



But it actually felt good on my 4cylinder toyota, a little bit of improved throttle response, and little more torque. Was a nice little addition, I can't complain.

Seems like the kind of mod that wouldn't do any harm as long as it was a good port match etc and wasn't so thick that it started to alter the runner length massively.

Yeah I'm looking into having one of these made for me to see if it helps. https://www.nopistons.com/forums/pub...IR#>/smile.gif

Oh they DO make these!

i have a spacer for my fc to put an fd UIM on it, it's .75" cnc machined aluminum, ive been thinking of running a co2 charge through it to see if it acts like an intercooler.



tons of possibilities for that little block.
