Epic!!!!!!
But one question, why did the motor/hp go flat at 5K?
Did you run out of ejector spray amount, pump pressure, or boost increasing pressure.
At your HP climb rate to 5K, it it did not go flat after that, should have been in the 800rwhp range at 6.2K instead.
Myself, it only 650rwhp in on the table, would have rather had the motor turned to produce that at red line instead with a clean climb (6.2K), which gives you a wider Rev range for useable HP for road/road course use instead.
Hence the higher that a motor will rev/ has in useable HP Rev range, the easier it is to drive the car.

belt slip on the first run as stated in the OP duty cycle was @ 52% WOT

Yeah I talked to Billy and he said it is perfect...he is overly pleased with it. Especially the Torque it made...the motor was built my Late Model Engines and Bryan at LME specced the cam based of the stroker motor and blower so it was all well put together.

This a 3.55" or 4" pulley? Going to try a Procharger race innercooler someday? Mine is making progress. Would be thrilled to just match these numbers. GJ man

The blue line does peak and hold from 5250-5750 then decline some. This isnt too far from the peaks of a lot of stock ls motored cars. Its more than likely the blower running out of steam. Even the smaller F series blowers do this on 400+ inch motors.

The procharger innercooler is good but a thicker "race" version came out about a month ago. White Lightning in the FI section had pretty good gains with it. Something like 100rwhp on a 1400RWHP F1X car.
An 8 or 10 rib flip drive will help. As would an A&A SC bracket. I'm hoping my 8 rib A&A will hold a 3.55" pulley.
