blackcat did for his 3.33

 

Don't think so but i'd do it anyways... cuz





You won't be happy with JUST a 3.33" in no time at all

 

That was my plan anyways...just wondering if it had to be done incase I didn't get to it tonight.

 

I think 3.125 or smaller gives a big diff on butt dyno. you boost faster with smaller pulleys too, little tap of gas pedal you are already in 0 on your boost gauge.

 

Yep, I had to file it down.

 

When I have the 3.33" I had it filed down a lil.. But withthe 2.87" I just went ahead and chopped the it off..

 

Sounds painful!







I hacked off more than needed too:

 

I just realized...the post that you need to grind, well, I stripped the threads out of the SC for that bolt before I even installed it.

Should I just cut it off, or is it needed to help support the supercharger as well?

 

Obviously YOU don't need it

If this post is completely removed, I wonder if it allows for a belt change without removing the S/C assembly... You'd probably still need to grind open that big hole where the center of the S/C pulley goes though.
Nice "side effect" of the procedure.
