I had a race this weekend, and on the last lap of the last race I thought I snapped the clutch cable.
Pedal flopped to the floor and I couldnt get it into gear.
I was able to rev match it into 4th and nurse it all the way around the cool down lap and roll into my spot in the paddock, no-one but me the wiser...

Anyway I get underneath and the aftermarket black plastic clutch pulley had MELTED and folded over letting the cable slip off.

I have the kerry hunter-like headers where the 4-1 collector is basically right next to the clutch pulley.

So I will probably built a heatshield for the trans in that area AND replace the pulley.

But before I order another black plastic pulley, dont I recall seeing pictures of an aluminum or brass clutch pulley from somewhere?

I sell the pulley in delrin with the new bushing for $16

Yep! Yours was the one that melted. I learned over the weekend what the melting point of Delrin is (Hint ~350F).

Thanks! I have been wondering the exact model
Now if I could only find good exhaust gaskets that fit.
I make my own to fit the larger pipes, but they blow out too often.
I ordered a set for the 911 stubs, but they are about 3/16 inch smaller than the ID and I dont want a "reversion lip" on my stub pipes :-)


On stubs and big flanges I don't even run gaskets. The flanges have to be at least 3/8" thick to do this without leaks.


Thanks, I might give that a try.
I have considered using the copper RTV that is supposed to be good to 700F, or cutting some gaskets out of just copper.
I wish I could just afford one of Cris's headers so I wont need gaskets ever again.

I still cant find the pulleys on ebay like 914sixer mentioned above
