Had the OEM power steering pulley go one time. Couldn't figure it out for a while was going tick-tick-tick. Popped an a aftermarket pulley and it stopped. never came back.
For me it started when I installed cams. Get a knocky knock sound at idle. Push in the clutch and it stops. Trans parts are making contact due to the lope. Car runs great.
On the stock bottom end I lost 2 rods and then the block at 530rwhp pushing 11lbs with a 3.2 pulley on a Saleen blower. Long tubes 3.73 automatic. It didn't like the RPM's.
I went with facing the rear. Was real cheap from Summit. I think they are 16 or maybe 18 inches. No HP drop on the dyno. I cut right in front of the axle and welded those suckers in. Took the drone right out and still sounds great. For 50 bucks was one of the best mods I did. Have MAC LT...
I bought MAC's on my 07 for my 06. Have the off road prochamber. For the money I'm very happy. No issues. Just wish they were longer (more of a mid length) the a full LT.
Did mine on a lift. Took me six hours by my self and thats with a lunch break. If you have an auto watch out for the vacuum line in top of the bell housing hitting the firewall when lifting the motor off the mounts. Was 10 something at the dealer.
Be careful what you wish for. I'm on my 2nd engine, Get rid of the POS plastic pulley. Get a real good belt as well. I can do 530RWHP with a stock CS pulley and a V-10 WP pulley and a 3.2, key bpoint is good tensioner and real good belt. Have long tubes and stage II cams, and I'm right at 11.5...
