Can anyone guess how much power my setup is putting down. Long story short was able to get up to 15 psi @ 5800 rpms before the head unit belt walked off the other day and destroyed my belts. My tuner didnt get to Dyno it so I'm kind of wondering what kind of power my car is pushing. He did say that the tires were coming loose at 80 mph. 
and it was prettty rich 9.75. Im using the Aster Bracket and didnt see any belt slip, I should have the belt resolved soon so can anyone give me some numbers and how much more boost I have still? This thing should spin up to 6500 so give me some numbers. I'm out of town right now so I cant work on the car. Tuner (great guy) said 4 good pulls and he should finalize my tune with AFR adjusted correctly. Any help appreciated
AES 390
F1A w/3.90 pulley
kooks headers 1 3/4 stepped to 1 7/8
TFS 220 heads
Ls6 Intake
Lonnies double pump
Injectors 80 lb.
Oh and Alky control dual 15 nozzels

Your easy 850 to the wheels. I just got mine off the dyno. It made 805rwhp on 14psi through a th400. I only have the 4.13 pulley (F1A) on mine.
Any ideas as to why mine would run out of steam before 6k? I thought the blower would keep chuggin after that point. I have Asters bracket.
I do have a LS6 intake, Stock TB.

What are you running 370, 390 or 402? I know the only reason mine stopped was because my belt walked at 5800 psi and I was pushing 15 lbs. If I calculated right my F1a should max out at 7000 rpm w/3.90 pulley. I dont know if my 390 will spin that high but that should be another 5 lbs easy.. As far as running out of steam check your race valve make sure its not opening up at that rpm.. I know when I connected my race valve, fuel regulator and hobbs switch I had some how connected it to a vacuum line that had a check valve that only went upto 7.5 lbs. My tuner didnt know what the hell until he figured it out and got vacuum from another source. Thats when he hit 15 lbs and my belt walked off.
