We have the S-281. Our Saleen was a low number car, #016 in 2005 production. If I am not mistaken, the extreme was offered later that year. I still have everything off of the car. Seats, headlights (HID), 20's. Everything is boxed up and labeled.

 

Why are you only seeing 12psi of boost with the 3.0" pully and the 10% overdrive tensioner?

 

Thats the funny thing, everybody else claims 14, My dyno numbers show 12.5

 

Jim said that that combo should be around 15-16psi. I have that same setup going in this week I'll post the dyno sheet when its done and let you know how much mine shows. How high is your elevation? What are your HP and TQ numbers?

 

My HP and torque numbers are lower b/c I am running through a C-4. So there will be a difference there. I am in Atlanta, but the boost number was made in Boca Raton at Diablosport's headquarters. Don't know what the elevation there is.
