that is the question. I just had a little accident with the new T-trim (blower pulley bolt backed out). Blower pulley shaft isn't damaged, but the bolt, washer and key are gone and the inside of the pulley took the brunt of the grinding.
I'm fixing the situation, but it seems that a switch to cogs could be a good alternative. The car will never be raced in a rib-only class, so what the hey? :D
I see some advantages like not having to torque down on the belt to prevent slippage, which means less load on blower and #1 main bearings.
How do I size cogged pulleys to match my current setup of a 7" crank pulley and a 2.95" blower pulley? Will there be any clearance issues with the water pump pulley? How much further out (towards the radiator) will a cogged crank pulley protrude vs an 8 rib setup?
Thanks!
