What cam and boost ?

Didnt take long for someone to ask the right questions.
Lets say 10psi (I dont really know but thats what we calculated pulleys for should be close). cam is a mike jones
Int @ seat 312 deg, net lift 647
Exh 316 deg, net lift 643

What would that be @ .050 and .200?

No thats duration at the seat as indicated. Intake 312 and Exh 316
And as indicated NET lift is Intake .647 and Exhaust .643

I cant give you .050 duration I dont have my cam card with me. But that should be enough for a guess. I cant give all my secrets....

Reminds me of this one a little; http://www.cranecams.com/index.php?s...41&lvl=2&prt=5

How much $ was the SCX upper?

Not looking for secrets, just comparing it to one of mine, I was seeing 10 lb of boost at 5000 rpm, 1106 hp and 1162 torgue, yours should be more at the higher RPM.

What size was your Procharger again? and what size motor? Do you remember what size pulleys you had to get the 10 psi.
I have the 7.75 crank and 5.5 compressor pulleys, and ordered the 8.25 crank and 6.0 compressor pulley. They didn't recommend going to anything smaller than the 5.5 due to slippage so I got a bigger crank pulley to test with.
I was busting you about secrets.

M-5, 598, for that pull I was running the 7.75-.875 crank pulley with the 5.5 compressor pulley. I was shooting for 15 lb, which is what I had at 6300. At some point the big pulleys will run you out of belt length.

I have the 70" belt for the 7.75 pulley and thougt about belt size so I also have the 71" for the 8.25. I should be set.
I dont understand are you saying the 7.75 with the 5.5 gave you 15psi @ 6300?
