Switched over to a header/megaphone exhaust and quickly melted the stock white plastic pulley on the transaxle. Wrapped the headers and collector with fiberglass tape and installed a black delrin pulley, and promptly melted that one too. The collector sits very close to the pulley. I'm racing the car so things are getting pretty hot under there. Anyone have or know where I can get a metal pulley. I know that some were produced a while back, so if you have one in your parts stash that you won't be using, I could certainly use it. Thanks, Mike.

A simple piece of roof flashing (or .040" aluminum if you want to be fancy) is all you need to block the radiant heat from the exhaust.
The header on my Integra Super Touring car flowed right below the oil pan, about 2" away. I was seeing stoopit oil temps. I added some aluminum flashing mounted about halfway between the header and oil pan. Oil temps dropped 30 degrees. Just make sure the flashing is not mounted up against the pulley, since conduction will get it there anyway. |
