No I do not have a dyno sheet for the 800+ the last dyno I had gotten showed 500+ HP 1000+ foot pounds, that was as high as the dyno went to. Dyno operator said it was well over 600HP+ that was before the additional parts I have added.
The 800HP is an estimation from running with other 800HP trucks. After the dyno I put in the new camshaft,bigger delivery valves, changed from Holset HX50 to the B-1...
