after doing numerous searches...i have found that there is no answer as to whether or not an aftermarket pulley can be advantageous or disadvantageous.

it's always back and forth..people for it and people against it...both with good facts.so it's really confusing.



so i was wondering if any of the big boys are using it....dynoflash,t.trix,buschur or ams?
because if they are then I would know if it's good or bad..lol



any help would be appreciated.

 

anyone ??

I have heard, and this is from mitsu techs, as well as honda techs, that the aftermarket pulleys will end up shortening your motors' life span. Something about harmonic balancers used with the stock ones that keep alot of the rotating mass in check.

 

i have heard that also

 

this applies to any stock motor practically...

 

I've heard different stories too. Curt Brown runs Unorthodox Racing UD pulley. 10.92@124 on stock turbo. 10.26@140 on GT-35R.
