Oops, forgot to take off the 14% for the lower pressure of 43 psi. So
taking the 233HP we get at 56 psi and derating it 14%. We have 233 - (233 *
0.14) = 233 - 33 = 200 HP. So taking all the derating factors (if they all
apply) and you could be limited to around 200HP at WOT. If I have not made
some error, then you could be pushing the limit with a Renesis - assuming 56
psi is indeed the pressure at which the flow is rated. Certainly no the
standard of 43 psi - but, hey, the rotary is not a standard engine either
