Thanks,
I was way past a normal compression check, my ECU does not stop me from hitting 300mph my HP stops it way before then (near 155-160).
I checked everything I could possibly check in my driveway, the oil was speard out over the rear of the engine and I could not tell where it came from, how fast it was leaking or if one of the recirculating breathers from the heads came off at one point in time and made a mess. So after cleaning it up and looking it over for a week I went out to play. While playing I got wooped up on by a 4cyl and I felt I should have been more powerful, So I thought I either have a streatched bolt or I am just chasing ghosts and my car really is slow. and that is when I did the last possible thing I could do to show me if I had a problem or not (without tearing the motor apart for a "maybe")
Acually my ECU would stop the car at 180 (Diablo tuner) but I can't get anywhere near 180 so it might as well be 300. I was just making a point.
And for the record I never said I thought I lost a cylinder, I knew I didn't because I allready checked. I was just at the end of looking into a possible problem.

His entire post was related to doing a compression check while the engine was running.

first off, checking compression while the engine is running is a proven method of diagnostics.... many things in a motor change under load.
heres a good example... youve got a weak headbolt on a boosted car. compression testing the motor at idle may show decent compression numbers, while when its got load on it, it may be stretching the bolt and allowing the HG to leak.
you guys are all so gung ho to hate but experience can come from listening not just doing... and at my age... 24.... i'm gonna go ahead and listen.

And just because the motor is running DOES NOT mean it has a load against it.
In reality one of the worst things you can do is rev your engine up with out a load against it.
Hell even GM has figured that out and implemented a measure to keep cars from free revving very high in an attempt to cull things of this nature.
Now if you want to be serious about loading the engine then you need to take your car to a dyno and do testing while the engine is actually loaded.

I've got a pair of DA seats in real nice condition for $50.
I'm getting off of here so call me if you are interested.

do you guys want to read one my my textbooks on engine performance and mechanical repair? b/c i take it you know that the volumetric efficency and compression is going to be lower with the engine running. an engine is mechanical not mysterious, if theres something wrong in the valve train its going to be evident and any stage and load of the engine. the only thing your going to do by checking the compression while running the engine is wet wash that cylinder and contaminate the oil, and cause unneaded drag on the motor.
oh and arron my sr made 12lbs of boost free revving. i dont recomend free revving a motor though, causes unneaded stress and strain on a motor
