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.

That kind of radiant heat is damaging a lot of other things besides that plastic pulley. I can't imagine what your trans oil temps look like. (IMG:style_emoticons/default/blink.gif)
Pick up one of these: https://www.harborfreight.com/hand-tools/th...eter-63985.html Point it at the trans, CV's, and clutch pulley after a hard run. This will give you a better idea of what you are dealing with as far as radiant heat. I would also invest in a wideband O2 set up and double check your fueling because if the exhaust is that hot your exhaust valves and seats probably aren't going to last long at all. If your fueling and ignition are spot on , then I would look into Jet-Hot or Zercotec not only to protect surrounding components but to lower engine bay temps and make more power. |
