would putting a smaller diameter tensioner pully on my jrsc k20a3 effect the boost?..i know using an accork crank pully allows you more boost, i just wasnt sure if the tensioner pully would do the same thing..the reason i ask is first the obvious clearance issues with the modified auto tensioner pully..secondly i was just wondering if anyone elsed had done this for either reason and what the results were..thanks- joep

Imma say no because all ur doing is changing a pully thats on bearings, the only benefit is running different size belts (smaller?)
When throwing on the k24 crank pulley it is attached to something mechanical, the enginges crank, which changes the dynamics of the belt system with a bigger crank pulley

No it will not. It will however affect belt slippage. Is there any particular reason you are wanting to run a smaller tension pulley?
