A quick underdrive pulley question...

[gregory97svt]

I bought a set of used u/d pulleys off ebay and it didnt come with the crankshaft pulley. I do, on the other hand, have the alternator and water pump pulleys. Can and should I install these without the crankshaft pulley?

Thanks!

you can install them for right now, but i'd still get the crank pulley.

you'll pick up a little, but half the power comes from the crank pulley itself

Will my belt still fit after this "halfway" installation?

yah.. it'll work perfectly fine with just the two pulleys.. my car only has the water pump/alternator pulleys on it. I still need to get the crank pulley on, it did give hp gains but not as much as it would with the crank pulley.

didnt changeing the pulleys without changing the crankshaft pully make you alternator put out wrong
