All right folks, I was on the lookout to find out the target MPG improvement and power while atkinsoning a GPZ 500 engine.
I found out in a thread in the car section that a 23% improvement is on the cards.
For power I made a simple cross between useful compression stroke and power and with the corrected stroke.
It does not take into account the exhaust cam.
Anyway, the result came out at 22 hp compared to the previous 58.
(edit : let's not forget the quoted HP for the Prius is obviously in its Otto mode 76 compared to the strict Otto version at 106)
Sounds OK to me .
How would you calculate it ?
