Technically, the intercooler should drop the pressure since it's cooling the temperature of the charge. PV=nrt. If you measure before and after the intercooler, if the temperature drops, then something on the left side of the equation must get smaller, and since "V" is a constant, then the measured pressure is going to drop as well. No different than the pressure on a nitrous bottle or your tires. Heat it up, and the pressure goes up, cool it off, and the pressure goes down.

Well here is the update.. Finally got a different style IC from procharger. It's the vertical flow 1300hp. Had to hassle with them to get it and it was suppose to be the 1550hp IC but they said the cost difference was to much to just give it to me.. BS!! Anyway I tested it out and am seeing a 2lb drop through the IC. Not to bad...
Still think something is up with my head unit now... With the strait pipe (no intercooler) I made 12lbs (intake reference). Added the vertical flow Intercooler I saw 10lbs with the 5.25 blower pulley. So thinking ok, I got this problem fixed decided to start swapping pulleys and see how boost pressures react. Swapped to the 4.75 pulley (should give 5lbs more boost) I saw 13lbs (intake reference). I went ahead and checked pre IC pressure and was at 15-15.5. So still about a 2lb diff.. Not bad..
Next I tried the 4.25 pulley, again should be 5more lbs.. Yielded 18ish lbs in intake about 20lbs pre Intercooler.
Well everything seems to be about right as far as the IC not restricting anymore. But here's the problem.. A 4.0 pulley will max my blower out and I might see 2 more lbs of boost.. To put a total of 20lbs in the intake.. I have a feeling my head unit is not working properly this blower should be over kill for this motor! I will get it on the dyno in the morning, max out the blower and see what it does, have a feeling I will be giving this blower back to PC for some testing..
Before I tell you guys my whole experiance with procharger and give my opinion on the quality of the kits (basiclly before I bash them). I will see if they make things right.. I would hope they will since I live just down the street from them..

New update.. Made 900rwhp today with a new cam that Martin Tick spec'd for me. That's 125hp more then the other cam. also now that I have the correct Intercooler installed I'm not having the restriction problem and am seeing 18lbs of boost. (I made 775 with this Intercooler and other cam). Just a little shy of my goal of 1k my fuel pump is maxed out and only able to rev to 6200 rpm. Will be looking into getting my fuel system up to par and will be tuning and dynoing again. Target rpm max is 7k so I think I will be close to that 1khp mark.
Thanks Tick performance for the good customer service and knowing your products!

Since I will be maxing the blower out at est. 21-22lbs I might have to change my setup to maximize the blower. Since it will cheaper to change compression then change FI setup to produce more cfm. (twins)!!

Yes I agree. I was playing with the specs on the motor and am really thinking its around 8.2 to 1. Might bump up the compression this winter to 10-1. Since I'm running e85 might as well reap the Benifits of it.

I'd say that's the highest HP per dollar gain you could find in that combination.
Glad to see it did so well for you!
If you have a graph of the old cam at 775rwhp and the new one at 900rwhp send it to me if you don't mind.
We're going to try to get the static in the 10.2:1 region which should put his dynamic at 7.8:1-7.9:1 if I remember my calculations correctly.
In your experience do you think with big blowers and E85, would that dynamic would be optimal?
I think it would be, and it would round out the finishing touches on taking this thing from being way under cammed and way to low compression ratio, to a street roaming monster!

Pulled the motor last weekend going to slap a new set of pistons in. Target CR should be 10.2:1.
Also figured out that a 12rib belt on an f1-x will slip a lot! Not recommended I don't care what PC says. Sprayed some belt dressing on it with the belt tighter then a fat guy in spandex. Went from 20-21lbs of boost to 29-30 and belt was still slipping! Pushed a little water so with the high CR I'm going to shoot for 20lbs boost and see what happens. TBC...
