Is this legit' on Q16 gasoline with a Procharger, or is this a happy dyno? And what of the engine moving around on that pass (look when the throttle is backed off)? Didn't seem to me like it was strapped down solid. Wouldn't this effect what the brake "sees"?

First of all, I was there and it is legit. His dyno is not happy. There have been several people on this board that have been there and dyno'd (me, Tony and Billy, Mark L). I dyno'd my motor there and it backed the number up (it actually made more HP at the track than it did on the pump). Second of all, I bet any dyno that is getting 1600+ ft. lbs. of torque put to is going to move. Even a motor with a front and mid-plate in the car can't keep it from flexing. Third of all, if you listen to him explain in the video at the end of the dyno pull he said that the 2301HP number was a "popcorn number" because he was getting off the throttle. We all discussed this after the video was shut off and believe that the 2301 number is very attainable and fairly easy for the simple fact that the I/C is only rated at 1800HP, plus you can't factor the "ram air" effect of going down the track and the air being forced in versus the blower having to suck the air in. Also, the motor could have took atleast another degree or two of timing and the AFR's were safe (not on the edge). So I'm guessing we left about 100HP on the table. The goal was to make 2000+HP and have the motor be able to live and that goal was achieved.
