Stock engine compression (with 10.5:1 compression ratio) is apparently 195-205psi
With the 1NZ-FXE (with 13:1 compression ratio) engine compression is appanrelty 245-260psi

prius engine compression 245-260Psi, Nanoss22 compression 240, so it means the compression ratio is about 12:1 to 12.5:1? wow, if the car use VP racing fuel, i think the power and torque gain will be great. Can't wait for the dyno result.....

I wonder what kind of power just the pistons will make and then if you actually tuned for it (maybe with the aem fic).

if he use high octane number for fuel like VP racing, increasing the compression from 10.5 to 12, with proper tuning for the ecu, he should have about 10 to 15 extra HP on crank.

The rough baseline for compression is approx 5hp for every 0.5 increase, so from 10.5 to 12.

I would also give the same answer 10 ~ 15 hp as well =)

I too was hoping for a big nasty dyno graph. something to coax me into doing something foolish with my money.
