15% SC + 2% crank pulley or 17% SC pulley?

[mobile23]

i got a 15% supercharge pulley but have not install yet. what i really want is a 17% pulley. shoud i just get a 2% oversize crank pulley? or just got mine sold and have a 17% SC pulley? is a 15% SC + 2% oversize pulley 100% = 17% pulley? will an oversize crank pulley kill my water pump alot faster? thanks

I think the jury is still out regarding the oversize crank pulley ... I'd sell the 15% and buy a 17%

There has been talk of the crank pulley mod causing long term problems with big end bearings, not too sure if this is the case but I would say just to be safe stick with the 17% sc pulley and leave the crank pulley alone...

^^^^ I agree.

I believe Tony*t3 has a 2 or 3% on Crank pulley on his Works. You might try asking him.

Cheers.

thanks guys

if you wanna sell your pulley.. pm me

[mobile23]

by the way, what about 17% SC pulley + standard size light weighted crank pulley? any problem with that set up??

[supercharged99]

i got 15 % pulley with 1% crank pulley.

the car responds far better with light weight crank,but the choice is yours...

You might need to change few parts if the larger crank pulley cause problem in the long run but I guess you will need to change just the supercharger with 17/19% SC pulley. Safer I guess...

Hmmm 17%SC+0% Crank pulley= Good idea? No harm?

what would be te pros on using an over driven crank pulley?

What is the difference on using a 15% + 2%, than using a 17% + 0 % ?

Does this 2% only applies to the SC? (I dont think so).


Thanks!

Doesn't the GTT kit use a reduced SC pulley and oversized crank pulley?

Alot of people have been running this for a long time with no probs
