Just a quick question. I have the stage 2 and I just got the stage 3 pulley to go on it. Do I have to do anything like disconnect the battery or anything to install the new pulley. Also, is there a how-to or anything to install it. Im sure its easy, I am just not sure how to get the belt off using the tensioner. Thanks a lot. Appreciate it.

Someone has to know...

Here is a how to pulley swap:

Yeah, I saw that but it didn't say what torque to tighten the bolts with either. I was just wondering if anyone has done this yet to see what they did. Thanks a lot.

anyone put the stage 3 on with the stage 2 set up?

 

Bolts get tightened to 15ft/lbs, thats from the stage 2 manual. I'd do it in a cris/cross pattern.

 

OK. Thanks man. I thought it was somewhere around 10-15. I'm just wondering if I should disconnect the battery while I do it so it can relearn. I never did that when I did the airbox mod. Probably wouldn't be a bad idea.

 

you dont have to do anything...


i have a 2.90" pulley which is smaller than a Stage 3 (2.99" pulley) and i have had no problems... either has anyone else who has done this.


go for it.

 

You should'nt have to take the super charger off.All you need is the socket for the Stage 2 bolts.You just losen the bolts, then relieve the tension off the belt and swap out the pulley.

 

dont know if it was just the dealer i brought it too...


but my stage 2 bolts were on the TIGHT.. i believe they impacted them on there


so you might wanna look into new bolts and/or a pulley from nherbst454

 

only one of my bolts was a pain the rest came out pretty easy. the hardest part was getting the belt back on. the stage 2 belt is extremely tight.
