Coke can? No. Going that small would be disasterous on a street car. Coffee can is more like it, simply underdriven.

I've always ran a race crank on my n/a motors with no charging/overheating problems...even with a stock alternator. Yes, these were street cars.


*edit...not saying you won't/can't see any problems, just i never did.

You're saying you had a 3" crank pulley on a street car? Most underdrive pulley kits have at least a 5.5-6" crank pulley, and many people have problems with those.

Yes, i've had it for years.

"Race" crank pullies are usually around 3" which would really underdrive your waterpump and whatever else is needed. It would be OK for the track if you had a good amount of time between runs and a good battery but it would probally be like no belt at idol, but I can't say from personal experience.

Yes, Jason is one of the race crank users. I remember him telling me about make a fist with my hand, and thats the size of the crank pulley. I have no experience with them per say either, but I guess you could try it and see how it acts.

BTW, Jason is the blue coupe for sale or are my eyes playing tricks on me.
