stillen guys plz advize
 

what size is the pulley that comes stock with the stillen supercharger kit anyone know because stillen don't seem to know.

also whats the size of our crankpulley i was told its the same size as the one used on the 350z 5.75"?

thxs

The Stock pulley size that comes with the Stillen kit is 3.12.

Your are correct on the stock crank pulley size of 5.75"

thxs for the info sir.
so stillen kit
3.12 stock <-----was seeing 9psi
2.95 upgrade 9lb pulley <--- seeing 10.5psi
2.75 upgrade 10lb pulley <-----(should see about 11-12 on the very top)

The 9 pound pulley is 2.75. For some reason Stillen didn't drop down to the next pulley size. I measured it and compared it to the 2.87 vortech 6 rib.

Are you sure i bought a 2.95 for vortech and the boost didnt go up that much stillen would not tell me if the 9 pound pulley was 2.75

Stillen doesnt offer a pulley upgrade for the kit. At least what I been told, I went out and copied Mr.squeeze( With his help) On my Stock kit I'm seeing 9-10 PSI.

Where can we purchase the 9 lbs pulley from?
Would you recommend the 2.75 upgrade or the 2.95 upgrade for this kit?

you get the pulley upgrade from vortech, I have the part numbers from Mr.Squezze just oredered everything last week, but you might want to cover the ven hole first, See my broke down thread, I had water in the SC Fluid. :(

Damm! just read your thread. That's horrible!!! So sorry. I will look at mine when I get it and see if it's covered or plugged.
So what is the part number and the cost of the pulley that Squeeze gave you?

Pm me

The small 9 pound pulley you can get from Stillen the make you sign a waver.You can also pick up a 8 rib one from Vortech as well.

I am about to order 2.80 Hi traction pulley from vortech and i have been getting some great knowledge from mr squezze i spoke to vortech and they said the hi traction 8 rib pulley grips better brecause its sand blasted. they say that if you dont have a hi traction pulley on the front 7 rib belts it wear it out 20% quicker so i plan on getting the pulley from vortech and sand blasting the fron 7 rib pulley to match the hi traction vortech pulley will let you know how i go
