antno Posted August 28, 2013 Share Posted August 28, 2013 I'm sure my engine builder will know what he's doing and also I have an aftermarket crank so it could be different. Sorry forgot to mention due to the crank pulley being bigger it over speeds all other pulley and I have heard on here that it has been causing alternators to break or damage batteries it would be advisable to make a larger pulley for the alternator especially if you are upping the revs. This will also affect the belt length but I wouldn't of thought by much Link to comment Share on other sites More sharing options...
Guest aspire Posted August 28, 2013 Share Posted August 28, 2013 Just make sure you hone out the inside of the ati centre. It's states the measurements in the instruction manual hi antno, do you run one of these on your car? i had read on the us site it needs a small amount removed, i think 0.0006" is the diference we are talking, which taken in to account is to much interferrance.

Kaan W Posted August 28, 2013 Share Posted August 28, 2013 what do you think the pros are? of having one. I think the main reason is they last longer than the oem piece but also look alot better. Link to comment Share on other sites More sharing options...
