The original post seems to imply that no after burner was involved,
note that w/o whch I read as WithOut.
I was told that a completely psychotic build w/o afterburning
Assuming ithe ntent is to drive a wheel(s?) ( which the shp question implies, please correct me if I am wrong) rather than push the thing like a jet I only have one question.
How do you plan to couple 6000hp from motorcycle to the ground with a wheel of any sort?
Seems things would start slipping well before the 6000hp point was reached unless the wheel had nubs that ran in a matching track or something.
Guess you could get a little extra "down" force by pointing the turbine exhaust to the sky.
In any case can't wait to see the video!
