I am running a paxton sn-89 supercharger on a stock motor...recently rebuilt and upgraded with sn-92 guts..the crank pully seems to be close to 8"(couldnt get exact measurement) and the blower pully is a tad bit over 4"...like prob 4.25" id say...what is your guestimate to how much boost im pulling?thanks.
dont all jump in here at once guys.
You do not have a gauge?

nope..kinda brok..just figured there had to be someone out there with a somewhat similar app. and knew what they had from it.
6psi is probably a good guess since the supercharger pulley is 4.25" and the crank is probably a 7"
my brother is running 7psi with the Sn-92 stock pulley i think its 4.25 he has a 3.75 but not putting it on! on a stock motor~
and yes the crank has a 7" on it~
I have that small line going from the oil filler tube to the sc,I was told to take that off(oil is now showing on the front of my motor since install) what do i need to do once i just disconnect then line?put it in as basic terms as possible please..Also I was told I need breathers in my valve covers,i have no holes~stock valve covers...I ve heard theve made them to plug straight into the oil fill,but they are import size and too small~any cheap ideas? and should all this help my oil spill problem? thank you so much.
Ford racing and K-n-N make a screw in breather for the stock valve cover that help out alot. Is your pcv connected to your intake as well? Cause if it is instead of venting your pressureizing it.
89 Coupe with parts stacked inside of it and about 30#'s of dust on it with no end in sight. :weird:
Although I am collecting parts for a 12.5:1 393 :D
how about I ended up getting 8lbs of boost at WOT......with the pullies listed by me in the posts above,wasnt expecting that at all.
