New LS1 Owners - Newbie Tech - Slp Crank Pulley

i installed it tonight. i hope its going to be ok, there was no way i could get it to torque to 240ft lbs. it seated all the way i think and then i TQ it to the 37ft lbs and got about 120 or so degress on it.. just went out and didnt throw a belt and the pulley didnt fall of so i think im good. i put a sh!t load of lock tight on the bolt..what do you guys think..i think she will be ok

Did you feel any more power?

revs quiker. dont know if i feel a whole lot of power. i had a buddy gain about 8 rwhp all thru the power range when he installed his. im not as rich as he is so i wont be dynoeing mine for a crank pulley..lol..im going to the track tomorrow night so i will let you know if i run any better

The 240 ft-lb torque is for an ARP bolt only...the additional 140 degree thing is for GM's torque to yield bolt. Ideally, you should have been able to get to the full 140 degrees (I think that's what it is) or at least 240 ft-lbs if you have the ARP bolt.

When I had my SLP pulley installed, the installer tightened it down with an impact wrench. I never checked it, but when I pulled it off a couple years later (just a couple weeks ago actually), I found that the bolt was only in there finger tight. At least the pulley hadn't started walking yet.

Moral of the story - if you want to take the chance on it being tight enough, so be it. Keep an eye on it, and don't just think it is going to be okay like I did. It damn near bit me in the ass.

if you used red loctite good luck getting it off ever esp if you used as much as you said its gonna be a FIGHT if you ever need to take it off

Take it from one who thought it was just like a mustang pulley :bang: . just watch your altenator gauge if it dont pick one day to the norm and the battery voltage is good you have a problem good luck.

did u remove any of the radiator support ect ect. to do the install

it wasnt necessary but i did remove mine when i did my pulley because i was also getting rid of AC.

I Didnt Have To Remove Any Rasiator Supports I Just Worked From Under The Car.thehardest Part Was Tring To Tap It On Straight With Everything In The Way..

Comes right off no problems. That stuff is not a permanint as everyone thinks.

alittle heat and it comes off everytime.
