so i saw on ebay that a lightweight crank pulley for an evo fits a ralliart im wondering if this is correct? If so anyone know a good light weight crank pulley that isnt an underdrive?

Also does having an underdrive effect the voltage coming from the alternator? i know the smaller crank pulley would turn the aternator less but how much does it effect the car?

 

It all depends on the ratio of the crank pulley to the other pulleys. The kit you seen was it the one that came with the alt. power steering and water pump pulley? Most people are worried about their light dimming from a underdrive pulley but what the should be worried about is the water pump turning slower.. Lightweight would be the way to go anyways from the pictures it looks like itll bolt it But I'm not 100% sure As I never bolted one on

 

true i never thought about the power steering pump or even the water pump. ideally id want just a light weight one same OD for the pulley as the oem.

anyone else??

 

IIRC evo crank pulley wont work on the 4g69

 

IIRC?? and so no evo crank would fit? oem or aftermarket?

 

Sorry I typed it in wrong the crank pulley I believe is just light weight not underdrive the water pump pulley was slightly smaller and light weight I have the factory 10in sub and have added HID headlights and have no dimming with the system on and the headlights on

 

Roadracemotorsports has an under-drive pulley for our Ralliarts. I have had it on mine for about 5 years with no issues.

 

so what is the harmonic balancer crankshaft pulley will fit to 4g69 ?

 

I've seen a few aftermarket adjustable timings pulleys as well as an underdrive pulley. I'll have to double check though...
