[QUOTE="98 Saleen Cobra, post: 16186473, member: 52734"] Well for those that have been following my build thread I recently sold my T56 magnum and threw in a Freddy Brown 4R70. Deal was to good to pass up for a brand new unit.. During the down time I also sold off my JT-trim as it was waaay out of steam. I was going backwards in boost before.. 15psi going down to 13psi from 6400-8200rpm or so. We did data logging at the track and didn't have to make any tune adjustments which was nice. The hit 18psi in 3rd crossing the traps at 8000rpm. Rest of the time it was in the 17psi range. The converter is way to tight. I could only get on the trans brake to 3000rpm, so leaving at 2.3psi lol. Converter is coming out next month for a restall and shooting for 9.0/8.9 @156mph.. RPM was dropping 2000rpm between shifts!! So there is a ton left in it. I didn't use the lock up on the converter this pass either. Run down of the trans setup is: Freddy Brown 4R70 no O/D built for 1500hp. Carbon Fiber drive shaft Circle D Converter Full lock up YSI with a 3.33" upper and 15% lower. Making 17-18psi. 17* of timing, E85.. The rest of the engine build is in my thread but basically: 10:1 stock displacement engine (billet I-beams, Accufab pistons) Foxlake stg 3 heads Custom Accufab cams Sullivan lower Custom upper Weldon fuel pump, ID17000's. 18" M/T Pro bracket radial Lots of suspension 4.10's 3100lbs w/o me in it and 3/4 tank of E85 Holley Dominator ECU Tons of fun and looking forward to getting the converter done, and 2step working :). Thew in some pics of the data log points.. My launch, my 1-2 at 8399rpm, and my trap. We have no clue what the power is as it was tuned or adjusted at the track. I'm guessing in and around 850-900rwhp though. I should also add, my previous best with the 6spd and a 18" Hoosier DR was 10.3@140mph with a 1.79 60ft.
