I'm searching for stock h22 dyno runs done on either a Mustang or Maha dyno.The reason is that I got the head off my jdm H22 ported last week and the garage's dyno program apparently was reading high when I did my base run??? It gave them a base run of 155whp on the mustang and their telling me it should have been 140-145whp.Today I went there to dyno the car with the ported head and it gave me 160whp so I'm a little pissed. Since I don't have any base run figures of a stock H22 I'm calling out to you to give me some honest figures and make some sense out of all this.This garage is known for doing great work and great service and since they just started using this dyno they blame it on lack of experience using this particular dyno and they don't have any other H22 passes to compare.Please help me out and thanks to those who do give me numbers...please remember only mustang or maha numbers.thanks again.

 

For reference, my H23 with I/H/E put down 140 on a mustang dyno so an H22 should be doing better than that.

 

Do you think 5whp more than your H23 would be justifyable.Thanks by the way.

 

mustang dyno's tend to read lower than most other dynos.

what are your mods. Port and polish? Your not gonna gain much of anything with just a port job on a stock head.

give us more info about your car.

 

-Jdm H22 with lsd into accord 2000 coupe.
-2.5 straight pipe.
-accord intake (for the moment) but prelude throttle body.
-P28 ecu.

...air/fuel is 13.5 all the way and the timing was also ajusted. Thanks to those who are helping out.

 

those numbers sound about right to me for a stock motor considering the mustang dyno reads low

 

So in other words I should be happy with 12-15whp gains and an average gain of 12lbs of trq for a $1000.port job? My next step is a cai and a good header which will be followed by Hondata s200...how's that?

 

ur not gonna gain **** from a port and polish without all the other accessories that usually get installed when a p&p is done. ie: cams
