Stage 3 Weistec smaller pulley
I currently run the 67mm pulley.
The next size down everyone runs seems to be a 60mm pulley but on Weistec’s site I can only see a 62mm pulley. Is that all they make now?
Cheers

I run a 56mm pulley on my newer gen blower, but this is on a m113K motor?

can you run 60mm on stock p31 motor, or does it have to be built?

pretty sure the 62mm is just an idle pulley not the 60mm blower pulley.

your car is one of the first that made me fall in love with weistec c63. Although I do want to put a 150 shot on just to experiment and have fun, but maybe I'll throw a 100 on top of the blower.

that info is not commonly given out too detailed. Mr747 gave me some info.

pump gas you should be fine on the stock system.

I was told you'll need 3 pumps on e85 or well you'll max out 2 450's.

I personally plan to run 2 e5lm pumps but it's not plug and play and will be upgrading the whole fuel system.
