Yeah, between RWD and FWD motors - because a RWD water pump is bigger (and sticks further out) it has a different offset pulley.
Hey there,
I'm looking at a set of lightweigh water pump / crank / alternator pulleys and wondering if there is any difference between the 20v and 16v models? I'm gathering there is but I thought I would just check to be 100%
Are there any con's to getting a set of these? and for moneys sake are they worth it?
Cheers
Thank you seamus
Ive fitted the same lightweight pulleys to fwd and rwd engines? Neither have chewed through belts or anything.
don't take offence meadan, but i don't really see how that's possible - the offset difference between RWD vs. FWD water pumps/pulleys is enough that it would/should kill belts or at least make HEAPS of noise.
no offence taken, that picture is really quite obvious.
I really wonder about the gains of these pulleys. What I am pretty confident in because of someones experiences on here is that over about 8000RPM the stanard speed water pump cavitates.

less rotating mass? i bought a set cheap a while back but need the front of a fwd pump then a themo fan setup... also need to tap some holes in the harmonic balancer for easier pulling off. main reason i bought them was the fact it has a single row balancer.
Having the weight that close to the crank would have a very small effect. Also if the keyway part of the pulley fails the key can curl out and stop the cams spinning, so pray your engine is non interference if it happens- which it did to me twice. I suggest a simple steel ring on the inside of the pulley for anyone doing this

what where your balancers made out of sam?
and surely it would make some difference, a flywheel is as close to the crank and people swear by light weight versions of those (yes, i understand it is larger but the principle is the same).
