Thought i'd post this question rather than email billetflow just in case any others were wondering the same thing. I've been reading all the bad things about the stock idlers failing and causing havoc when they do. And a few days ago i got a REAL bad whine and a few random clicks and clacks from the front of the motor at idle and up through the rpm... like BAD bearings. I thought it was my blower making the noise, but after reading some threads it sounds like the idler pulley symptoms. And as of right now, i'm not sure if i want to pulley the car or not. My question is, can run billetflow's 4 piece idler set w/ my stock blower pulley? Wouldnt i just need to get a 77in belt and thats it? And then if i wanted to put a smaller blower pulley on in the future, couldn't i just get a shorter belt and thats it?? Thanks in advance.
