SC12 Vs. SC14 Supercharger Pulley

Lex · 01-31-2007, 09:39 AM

Hey Gang,

This is David and I run this forum www.lextreme.com. Anyway, I have a quick question for all you Mr. 2 experts. I would like to know if the SC12 pulley interchangeable with SC14. I recently got a free Previa from my neighbor and would like to increase the boost. Perhaps if possible the SC12 pulley would be a bolt on.

Did you want to speed up the SC14? Normally crank and other pulleys around the s/c are changed.

Is there even a size difference in pulleys?

EDIT:
Welcome to the forum BTW Dave, how is lextreme doing?

I measured the stock SC14 and its 4". I am looking for 3" pulley to make some more hp for this family hauler. Perhaps i might have to go with a custom made.

Yea as long as all the air can be bypassed at idle and what not as the stock setup the clutch disables the s/c

they do not swap one for one. the splines are not the same length on the shaft. Some machining can make it work, but it is beyond my diy capabilities.

Real curious about that sc-14 as I've never seen one, do you have pics?
