I don't have the graph handy but if you search threads I have started then you will see it. It was on a DD but a sim correc. Factor was used, they stated it was equiv within 1-2 hp of what the dj down the road reads...they've proven that. My car pulls good, I have proven it against de and hour motors that I have run against with similar mods.

no one is calling you a liar... maybe the 4.08FD needs to be considered in the equation, i didn't see that!
i guess we can all agree...
notice that 75-77 lb/ft per liter at flywheel is a very high number for N/A
you have a very torque'y motor, congratulations

Where people get confused is that driveline loss increases with rotational speed of components, so you cannot use the same 15% for HP peak rpm as you do for mid rpm torque where losses might be 10% or less!
The only way to measure engine output at flywheel is to pull engine and place on a dyno..............all this reverse calculation from a chasssis dyno is full of errors.

Even in this case, dyno should be the same dyno and conditions should be similar, although the result is already inaccurate so correction factors for ambient conditions will play a small role. In any case, it's better than measuring raw numbers, which means nothing.
