This set up has already made more power with 26lbs of boost than the car did with 29lbs of boost with a KB, or 26lbs of boost when it was turbo only. I'll have more video of it soon, as we just got the MAF extension in this morning. Also remember, the 700rwhp is on a Mustang MD-1100SE dyno, and is only at 5000rpm. We still got to spin it up another 1500rpm at least.

I'm compariing it to my Twin Turbo setup. At 19PSI I made around 900RWHP through a TH400 tranny. Back in the old days the diesel trucks were using blower with turbo. It died out when they perfected the turbocharging. Now at 23PSI my setup produces about 100RRWHP more. So around 1000RWHP. I'm thinking that blower is holding you back. The nice thing about pure turbocharging is that you simply hit a button to change the boost. I can run 8PSI on street tires and 23PSI at the track on race gas and slicks. With a turbo in front I would assume you can do the same somewhat. Dial it down for the street and conditions. I'd still sell the blower and go twins if they fit.

I agree with you. In fact it would scare me to even think about calculating the forces going on in that setup. You build X-PSI which runs into the supercharger which compresses air which is already compressed by the Turbocharger. Changing the spin rate of the supercharger without changing boost and vice versa would be cause an inbalance and you lose the efficiency. Interesting project though please keep us posted on it.

Check out the Hellion kits out there.
I've seen PSI on an 03/04 4V range from high 30's to low 40's through compound boosting.
It's sick.
Sick as in you would have some type of mental illness to even attempt such a thing not knowing the end result. The fact that it is actually VERY effective is just ***** out awesome.
Okay, I'll stop thread jacking.
