Here's my 103ci 10.8 comp night train with stock heads and throttle body s&s hp103 cams
This run was in 4th but 5rh showed pretty much the same and 6rh maxed out the dyno speed. Feels quick on the road turned and built by me not too sure why the tq is so high but it's a mainline car dyno

The mainline dyno has a bike setting

and 113 HP with stock heads would be alright too lol.

hp is derived by torque x rpm / 5252
so when it spits out 155 ft lb the hp is always gonna be inflated.
as said, as long as the AFR is spot on, the Hp readout is just a number on a screen. To build and tune it yourself is a feat upon itself.

Curve looks good. Car dyno numbers don't seem to work for bikes. If it's a good combo of parts and well tuned it might make 100hp which is the limit of stock heads

the mainline dyno made in Australia by a guy who worked for motec.
so would be good, but as dyno Harley said the settings are all over the place, see it too 10.5seconds, thats a long time.

Been doing this for a while and every now and then comes along a truly astounding engine , and this is one!! My poor old Dyna in its current guise has a indicated BMEP of 156psi .The one listed above has a BMEP of 229psi .Brake Mean Effective Pressure is a calculation used to make dissimilar engines comparable in their efficiency [IE;reducing the variable calculations to a raw pounds per square inch figure ],so the one above and mine being near identical in their layout shows i have a lot to learn.
