anyone running this plenum? i just ordered one from sumitt. nice looking piece, figured it should be as good or better than the c&l i had.

Exact casting of a C&L, just no logos, then I port/polished and gasket matched.
You have a leak somewhere.I like mine, except it whistles. Sounds sort of like blowing over the top of an open coke bottle. Did your C&L whistle?

You have a leak somewhere.

I thought I had eliminated any chance of a leak, and that the design of the plenum itself caused the whistle. I'll triple check it.![]()
I tefloned the threads of all the fittings that go into it, and snugged them down tight. I'm still using the stock tb. The gaskets seemed fine. I guess the source of a leak would be tb to plenum or plenum to manifold.

I put a little bead of RTV between my plenum and TB...just to be sure.

Does the RTV replace the gasket?![]()
