Hey guys-thanks for the props! Here is the graph, video's to come shortly:
I can't complain-almost 800 rwhp through a locked auto with 347 cubes is pretty stout-the torque is what really get's me. We had one pull and it was around 723. the car was running fairly rich in the midrange area like 10.5-10.85 then leaned out to 12.5. Then got it down to 11.5 on top and it came close to 800. I just got fed up and called it quits. Lots of little things to sort out. First off I couldn't log boost-don't know why but it wouldn't. I was told it was around 18-19psi then leveled off. I don't know power falls off at 6200-I was thinking maybe I installed the cam wrong or it's degreed wrong but if that was the case then the torque would of come in sooner as well. It's a healthy cam-10 degrees bigger than last year so it should pull right up to 6800-imagine how much power it would make then?
Injectors are maxed-130% duty cycle-even with a dual meth setup-time for a injector driver and some big injectors-these 60's are not cutting it.
Boost seems to go flat at the top when HP drops-my bov might be opening-I'll get that sorted out right away.
No signs of belt slip-still on the same belt the car was fired up on. This F1R is sick-i'm using a 4.13 pulley-I can still go down to a 3.75-this thing is sick!!!!Did I mention this cam has like well over 60 degrees of overlap-so much for boost loss-lol!!!
Dave at CDN performance built me a nice sick motor-nothing like a big blower and small cubes. I'll post more info-tomorrow-my heads going to split with all the thinking i'm going to be doing tonite!
Oh yeah-pump gas!!!

Are any of you guys running the 60's with 800 rwhp or more? I'm looking at those RC 75lb's-thye make them in hi-impedance. I also need to get a boost referenced regulator. My PE table is like 1.10 to like 5 grand, then 1.2 at 5-6 then 2.1 at 6grand up. Right at 6 grand you see fuel pressure go from 60psi to 40-could that be due to the pe table jump?
