I finally got mine out, and it's not up to par yet. It's a 572 Predator, and it took lots-o-money to finish and get going. I ran a best of 7.66@166 on the brakes during eliminations. It only 60's in the 1.14-1.17 zone because the converter is Way too tight for this combo. It make max torque at 6500 and HP at 7700, so it can't flash the converter and is very lazy out of the hole. If I had NOS, it would run lot's better, but I don't. I have a new converter on order, and will be heading down to sea level next week. Oh...I forgot to mention, our track was 8000ft corrected altitude.
