So the stock Saleen supershaker comes with a 3.675 pulley. What boost/hp dif would you expect if changed to a 3.6 pulley, and I assume you would need a new tune? What would need adjusted in said tune?

JDM saleen pulley & boost table - http://www.teamjdm.com/shop/product_...roducts_id=189

Not sure what to think of that table. I've seen claims of those pulley having different boost than what's listed there.

Yeah, I saw 1.5 psi less on most all those sizes. Perhaps those boost numbers would be valid on a 30 degree day, but.....

I'm seeing 12 pounds at the top of 3rd and into 4th with a 3.2 pulley in the 80+ degree South Florida heat.

Black GT

I notice slight differences between JDM & Brenspeed with the 3" pulley boost levels and Brenspeed offers a 2.8" pulley while JDM doesn't. Not that it would make much difference at that level.

JDM
3.0 = 13.5 psi
3.2 = 11.5 psi
3.4 = 9.5 psi
3.6 = 7.5 psi
3.8 = 5.5 psi

Brenspeed
2.8 = 14 psi
3.0 = 13 psi
3.2 = 11.5 psi
3.4 = 9.5 psi
3.6 = 7.5 psi

BRENSPEED

The current pulley size on your super shaker is a 3.875. A 3.6 pulley puts out between 6.5 to 7.5 psi depending on elevation. A new belt would also be needed with the pulley change. If you are currently running a Brenspeed tune and the pulley and belt is purchased from us, your tune will be updated for free and can be e-mailed to you.

If you have any more questions feel free to call Brenspeed or just send me a PM
Hope that helps
