i was wondering if anybody knows the size (diameter) of the standard pulley that comes with the magnacharger sc kit (on the front of the sc itself)? Also, what kind of boost levels are to be expected with that kit?
Thanks!

Mine is 3.4" and I run 9lbs. We thought about going to a 2.8", but decided not to run the boost that high on pump gas. (And no, I do not know what that would have produced.)

BTW, the size of your pulley is stamped on the front of it. I mention that because someone on this forum did not know it and was trying to measure it . Their name will stay with me.

I just checked mine and the pulley says, 3.10.

Ken do you use the same belt with the smaller pulley? 9 pounds of boost sounds like that much more fun.

I never checked the belt, but it has been replaced twice. I will check the size for you.

What boost are you running? No one else has ever mentioned it.

KenP, Kirk,
thanks for the info. duh! i found the printing on the pulley now do. i think i go and have a couple more smokes now....

here is the reason for my st... question: a few days ago i found out that something has gone horribly wrong because now the engine has no compression. we are currently tearing it down to get it fixed (i hope it is just the headgasket; don't know yet...). as soon as that is done i will verify everything with the stock set-up and then i will put the kit back on.
i can not make sense out of it, that's why i wanted to make sure the right pulley is on and it is.
right now i am a little clueless... as you can see in an earlier post (magnacharger installation problems) i had trouble getting it to run from pretty much the get go.
normally i can read directions fairley well and the guys who put it on are professionals....does not make sense why the engine would let go...
ideas anybody?

Mine is a 3.1--came with the magneson---I finally wnet out and looked----Ken---wonder why 3.4?

What boost are you guys pulling?
