We measure flywheel H.P. corrections for barometric pressure, humidity, and temperature. We do not use MFG. correction factor. 3.8 & 4.2 E-type good engine will have up to 190 flywheel H.P.. Jaguar listed it 265 H.P.. All auto MFG. had a correction factor.
My first engine dyno'ed at 256 H.P.. 9 H.P. under advertised H.P. but a good race engine in its day. In 1990 we broke 302 H.P. and set or goal at 400 H.P. Listed are some dates and H.P. readings over the years
