under drive ?

[tkareno]

i am putting on an electric water pump and electric fan, so i need to get a new alternator and while everything is out of my car i want to get new clean pulleys, but seeing that i cant use the waterpump pulley, is it worth getting them just for the crankshaft and alternator?

Any places sell just the crankshaft pulley underdrive

its not worth it. especially if you are putting on an electric water pump. the under drive pullies slow down accesories to reduce drag on the crank and your alternator is going to need all the spin time it can get to power an E fan and E pump.

just powder coat your stock ones

ok thanks

could possibly find a smaller alternator pulley to offset the drag that will be placed on it, but I think that the juice would not be worth the squeeze.

summitracing.com sells just the crank pulley.

Consider an ASP race crank pulley

Buy just the crank pulley.

Then buy an ASP 1 7/8 Overdrive alt pulley.


Call it a day
