Pulleys

[ProZac]

What size pulleys do u guys got on the SN-92 and how much boost u running.

[ProZac]

U all got stock pullys on yours? or what

I am interested as well, but more along the line of "what size pullies are available."

I have seen I think 3.25 up to 4 inch in .25 increments. I hope there is a 4.25 inch out there. I am thinking that I will go dual SC someday :)

Come on guys u have to have some aftermarket pullys on ur Sn-92's

I don't think anyone wants to go to far with a smaller pulley because the blower will creat too much heat and eventually die. I have a smaller pulley with my blower but it came with it and i haven't put it on. If i was you i would get an oil cooler to keep the temps down if your going to use a smaller pulley. You could call Paradise wheels and ask them what they recommend.

Yeah ordered a 3.75 from there how much boost should i be running now with a 3.75 and stock crank pulley?

[oray777]

Prozac-what was the pulley size you had on there before you got the 3.75?

[ProZac]

Umm not sure how do i measure it?

[ProZac]

i measured it its like a 4.25

Doesn't seem too small of a pulley. I believe you have to use a smaller pulley belt but not quite sure. I would definitely use an oil cooler if your going to use the smaller pulley.

it has a oil cooler on it but thinking of getting a bigger one ill telll u moe when i hook my boost gauge up and tell u what it was at with stock and the 3.75 k and i measred the crank and it was 7" thats what i need right.?
