Looks great. Be sure to post up the dyno charts. Are you using the stock pistons and liners? If so, what is the max power on them? Also, what head studs did you go with?
It almost sounds quieter than before. Will have to check it out when you get it home.
It must just be that video, because that was taken on straight pipes to simply get it ready for the event. I'm having a new exhaust with boost activated cutouts being built as we speak, it should be ready this weekend and then tuning can begin.
The original plan was to modify the current exhaust, but I got a good offer on it and it just made more sense to start from scratch at this point

Dynos will absolutely be posted when they are ready.
I am using stock pistons and liners
Head studs are 10MM, raceware if I recall, but I don't have it all in front of me at the office
For those of you questioning the latest iteration of the ERP/RPS clutch. I will admit they've had issues in the past, even on my old clutch, but they are listening. I had a long conversation with someone (forget the name) over there before choosing to stick with them. He really put my mind at ease with the changes being made and the testing being conducted.
This video shows just how much of an improvement this update is.

He is on stock pistons and liners at 1361 whp. Oh and 10mm raceware head studs.
I have been studying fasteners and torquing procedures since m42racer brought it to my attention. I think that Tim has developed an angle torquing method that gets the racewear head studs stretched to the perfect clamping force that is evenly loaded between studs. This is the key to his success with them. My experience with torquing rod bolts has shown about a half thousanth varience between bolts torqued at the same wrench setting. The higher you torque the more it varies. These differences in bolt stretch compromise the head seal by overloading certain bolts. Evenly stretched bolts are better than the sum of their parts. I am working on a procedure for my ARP 12's.
A couple of updates...last night we made 717WHP / 581 TQ on 93 Oct. 19.5 peak boost, 108 deg. ambient temp
Then we swapped the 93 for some E85, and capped the night at 1033WHP. This was while showing 11.8 volts charging (bad alt. cable) and fuel pressure falling.
