Actually on a dynojet, torque is calculated from the measured horsepower and rpm.

it has a progressive controller switch and we just rolled into on the dyno. Keeping a small ride a long mower on a roller isnt a easy take lol!

Whats really amazing is that the engine components were all designed over 1000% too strong from the factory. Thats Supra territory.

Right but on a dynojet the fake graph could simply be caused by a bad tach wire....

PS I ran my mower on a 50% percent nitromethane/gas mix before. It was a 3 horse briggs. I didnt dyno it but the muffler and head lit up the evening quite nicely, for quite a few minutes.

Reffer to post # 1. If you look on streetfire.net you can see the abuse our test mower took! The motor must be japanese or something.

Hell Ya When we raced his Z3 vs the mower thats the only way he could see me going by him was my glowing muffler, being that it doesnt have a head light.

Oh I must be in the wrong place. I saw the dyno #'s and thought that this was a Honda thread. Sorry. Goodby.
