very good point 9sec9
I believe I have seen people running 30-32psi on the greens and FP mentions on their site about 30psi on race gas in their blurbs. Not sure on what shaft speed will be at at that level, but deff a valid point.

Here's a pic from our logs in 2007 on the FP-Green and on Buschur's Mustang Dyno. The peak boost was set to 36-37 and you can see the fall off by 7031 rpms. The whp at that point shows 443 whp. No question, the shaft speed was well in excess of 150K. Key to the power is keeping the boosted air cool.

+1 would you mind throwing out the list of mods?

Looks like someone is moving my pictures around on photobucket. Anyway, long time ago as far as mods, but basically Jun 272's, and FULL Buschur built parts with Stage 3 and stock ECU at THAT time if I recall. Complete list can be seen somewhere in this thread:

The 'old' FP EVO Green max useable shaft speed at STP is 162K, for the new FP EVO HTA Green max useable shaft speed is 153K.
Exceeding this only results in excessive exhaust pressure and hot air.

Well, you can only stuff so much **** in a 5 lb bag.
BTW we've had the old green to 185K and the new one to 168K. Doesn't do any good. Holding shaft speed to not exceed max always results in better dyno numbers. Can't get it in if you can't get it out.

I have the 25psi wastegate on my car. Go look at my dyno of before and after. it is a 30lb vs. 35lbs but you can see that it held 5+lbs more all the way to redline. I had the stock wastegate on the 30lb run and it was preloaded as far as it would go. It made a big difference over the stock wastegate! I picked up a $#!^ ton of mid-range torque and horsepower. https://www.evolutionm.net/forums/7314465-post62.html
Your gains are ridiculous.
