my resaults for the compression test on my S5 N/A motor.

front rotor 78-80
rear rotor 70-73

i used a conventional compression tester.

also from what i've heard is that you get higher compression numbers once the engine is up to normal temps and then you let it sit to cool down for 30 mins or so then compresson test it. is that true?

are these numbers still good for the motor to run? cause i plan on swapping this motor into another fc.

so what are your guy's thoughts?

 

DAMNIT!!!!! i forgot the person that was cranking the motor while i checked the gauge didnt put his foot down on the gas pedal. LMAO FAIL!!! i will post resaults again tonight. hahahaha

 

Pretty low.
That said, mine's been running for nearly three years on 80-85 psi with no starting or flooding issues...ever.

And with that said, I wouldn't go to the trouble of swapping it into another car without a rebuild.

 

i didnt know flooring it made a difference. maybe that is why my numbers were a little low too. Hmm..

 

yeah when you do compression test you're supposed to have the accel pedal down to the floor. still waiting on my brother to get home so i have a person to crank the motor......

 

hahah ok just got done with the test again doing it right this time xD

front rotor: 92-94
rear rotor: 88-90

so yeah learn from my mistakes people.
i guess im gonna swap this motor into my next fc now.
