Engine Questions

[MrStock]

Hi,

i got some questions, would be nice if someone has some answers for me.
My 02er WRX Engine was blown up on Dyno, it put with only full exhaust 250 hp on wheels, than died off with mass blue air out of the exhaust. There was no mechanic sound or anything, it was like turning off the ignition.

A/F was a little bit lean, but not really to worry. Before i went on Dyno i build in an AP Fuel Rail Kit in, cause my stock fuel lines got broken, i wanted to fix it right and forever. Since that the engines is reving up hardly with no gear in, but while driving its normal. Sometimes it lags very shortly after shifting, but most of the time i didnt notice it.

I think about wrong fuel pressure, maybe you got some tips? Dont want to put the rebuilded engine in and **** it up another time.

Thank you!

Trying to put the log file in today!

It's really hard to understand what you are trying to say.

MrStock seems to be located in AT so there may be a language barrier. However, if I read it correctly, your motor failed on the dyno? If that is the case, there should be a log with data that describes what exactly happened. Start there and see if you can figure out whether there was a fuel problem or not. You say it was not lean enough to worry, but obviously something went wrong anyway. Was it fuel, timing, boost, or a combination that caused the issue? Once you find out what it was, then you can look into correcting the problem to avoid a repetition in the future.

It is hard to overcome language barriers or difficulties online.

It may help solve your problem if you simply try to reword your post. Sometimes just saying the same thing a little differently helps us understand better.

I do not mean to be offensive at all, but we are going to have a hard time helping you without a clear description of the problem. Until then we are taking educated guesses at best.
