Well I just finished the F22 swap into my Ap1 and here is the dyno comparison.
Before- 2001 F20 -AEM V2, T1R test pipe, spugen single round exhaust and dyno tuned VAFC2
After-same mods just F22 long block

 

If you don't mind me asking, what happened to the old 2.0L?
Nice numbers btw.

 

sweet 10hp 10trq gain nice!

 

broken valve, check out the link

How positive are you that testing conditions were similar, if not exact?

 

Very, temp in the low 60's and low humidity.

 

so, your bolt on F20c only made 201 to the wheels? and the stock F22 made 211? sounds like your old motor was VERY sick before it died. that sounds about right for a F22, but not for a modded f20 at all!

 

did not you read, the f22 has the same mods

 

ah, i see. but still exhaust and vafc and only 201 to the wheels, that a very broken F20. my bud with a stock 01 just pumped out 205/131 on the same mustang dyno i pull on.

 

^ He's not using a Mustang dyno. But, yes... even on a dynojet, stock '01 numbers should be 195-200.
