I already used 7/16 stuff when I first installed the supercharger BUT its still a great idea to use larger dia spacers, thanks Gary, Smitty

Just curious,,

Would a M3 have less of a problem with belt slippage due to the greater internal step up ratio which would allow you to run a larger pulley to get the same boost ?

in the past i have welded 1/4'' flat stock to each of the spacer tubes and connected all them together to keep the spavers from rocking...figure out where the procharger is mounted now ,,,then remove it from the bracket and take 1/4'' flat stock the mock the plate up between the spacers to stigffin up the spacers..if procharger was smart they would have had the spacer part casted onto one solid piece..

You have the right idea, but I have a m-3 already. IF I had a m-4 or m-5 I could run a bigger pulley and have less slip because of the greater contact area!

That sounds like another good idea worth looking at!

i went with a larger blower pulley and innovator west custom crank pulley made to spec

I thought you had a M3sc which is a 4.1 internal step up where as the non sc is a 4.44 internal step up ratio..
Soo theatrically instead of running a 3.7" pulley, The "non sc" would use a 4" pulley to get the same boost.. Don't know if that would be enough of a difference in diameter to help at all...

You are correct, I have a m-3sc , I was thinking you meant I had a m-1 and needed a bigger one, I wouldn't switch from a m-3sc to a m-3 std as I have already had a Procharger self destruct internally and wouldn't want to deal with worrying about contamination but I did have virtually no slip when I ran a 4.250/4.00 12 rib pulley in the past .
so far I have seen 3 good suggestions that I am going to look hard at:
1.re-inforcing head unit bracket and machining bigger spacers
2. having pulleys Carbonite coated
and then the newest idea I just saw
3. Have a bigger yet pulley custom built for crankshaft

That's a great idea too but just went on their website and see they are no longer making any custom crank pulleys. Anywhere else you know of that does it?
