Celica Forums General Discussion Exterior who has UR pulleys? are they safe?

i heard something about installing after-stock pulleys and messing up your engine because of the vibrations and stuff (you can tell i know so much about cars ha,ha). well after considering getting a "safe" AEM (which i hear doesn't give much HP) ,what about Unorthodox? anyone here happy with theirs and have there been any porblems using them in our celicas?

I have the AEM pully on my 02 Celica GT. It doesn't produce too much HP, but i trust it a little more than Unorthadox because of the engine saftey factor. You aren't going to get too much out of just an alternator pulley anyway. Play it safe. AEM is cheaper too, I believe.
