Author Topic:   Staying cool on gas

I've heared that running a 1 to 1 pulley set up is the way to go to keep a motor cool on gas. Is there any truth to this, & if so where do you get the pulley? I've checked with our local race shop & they don't carry them, & say it won't work. Thanks.

Having a good fan shroud helps.

there is all kinda of tricks to help cool her down but the 1:1 definatly helps look arounfd in the big parts catologs like speedway or jr motorsoprts or midwest think performance bodies also carries them

obviously a 1:1 setup are the same size pulleys so if you have the water pump pulley slightly larger, I think it would be a 25% reduction? Wouldn't that be better due to slowing the water pump down a bit more?

Motors running at 7000 rpm. Water pump running at 25% slower than that; approx 5500-6000rpms? Math might be off but you get the general idea?

Am i on the right path?

I think a dual pass radiator is worth the money on gas. Your two barrel can get the motor hot at high RPM.

Good luck,

the 25% reduction was to slow and was heating up undercaution and when i let it idle
