3.75 pulley

[shopo27]

Will a 3.75 pulley part number 2H036-375 fit a sn93?

[Michael]

Which manufacturer is that pulley part number from?

Its a paxton part number

If it's for a current Paxton supercharger (ie. Novi 1200, Novi 1500, Novi 2000, Novi SL, etc.. ) then I don't think it'll fit (although I could be wrong).

For SN pulley's you may need to contact BlowerWorks (www.blowerworks.net) to see if they have a pulley to fit your application. They are a Corvette supercharging specialist shop, but they have pulleys in 6, 8, and 10 rib configurations in 12 different sizes from 2.650" dia. to 4.250" dia. Their pulleys use a taper-lock design to hold the pulley onto the input shaft of the blower, which does away with the need for the shaft key.

Just make sure whichever size blower pulley you decide to install won't spin your SN beyond 40,000rpm.

I know a few people have bought a procharger pulley, then took it to a local machine shop and cut the proper key way into it. This is what I will do eventually because last time I called USP.com... (forgot the site name lol), along with other places, they told me they wont have any 3.75" pulleys in for a couple months. I dont want to spend another $110 on a pulley from Paradise either.
