http://shop.ebay.com/?_from=R40&_tr...+underdrive+pulleys&_sacat=See-All-Categories even though they say they are underdrive, they are all the same diameter as OEM, meaning they are not underdrive. ive been told they fit most all EJ series engines (obviously crank pulley will but i was iffy on the alt and steering pump pulleys) i have also been told they are very high quality and work perfectly. and theyre only $15! im gonna have to get me a set of these very soon
Be aware that doing both the crank and alternator pulley makes the alternator spin so slow that it doesn't charge while at idle.
They are a waste of your time (imo) you wont feel a difference. AND none of the belts work right for them.
ive heard they work great with throttle response (but thats about it) and that the belts actually worked really well with these ones. ive got a bid on a set, so ill let you know how it goes.
thats a good point. well i dunno, ive already basically got them ordered so ill put them on and if i dont like them, i'll sell them.
Its more of a show piece than anything. The gains are marginal, and only noticed (if at all) in lower gears.
I had a Perrin lightweight crank pulley. I wasn't able to be balanced with the crank. We put on the STOCK crank pulley, it's perfectly balanced where nothing had to be taken off or added onto it. My internals where rotated balanced and weight balanced. From front crank pulley, crankshaft sprocket, crankshaft, rods, pistons, flywheel, pressure plate WITH bolts.
