Diabolical!

+1. All of the meaningful info you get from a dyno comes from 4th gear at WOT.

The stock clutch in mine will slip in 3rd and 4th gear every now and then, especially when I am at the track and have done my 2nd gear burn out and have gotten the clutch nice and hot. I'd really like to see how much boost you are putting out on the dyno....I may have to order the 12 lb pulley and have another trip to VMP and really start playing with some fire.

Wow and I have been worried upping the boost to 10psi, but mine is a DD.

Good luck.

I want to get my car dynoed again now that i have a stronger clutch, but the wife doesn't see the point. There is no freaking point, damn! Women are so freaking stingy!

I couldn't even feel my stock clutch slipping until I went to pass someone in 3rd gear and the car wouldn't go.

Let me see if I can shed some light.

I have the FRPP Whipple H/O kit part number M-6066-M117.

Whe I purchased the kit this summer, the kit was rated at 500hp. Now, the exact same part number is rated at 550hp.

This was accomplished by changing the pulley from a 3.500" to a 3.250".

Mine originally came with the 3.500" (since mine was before the change) and I upgraded mine to the 3.250" My boost changed from approximately 9.5psi to 11.5psi. When it was hot out (115 degrees) and even now when its in the 40s, I have remained consitant maximum boost at about 11.5psi.

Hope this helps.
