compression test results at 169,XXX......
from passenger side towards right

Dry:
5 cranks - 60,60,55,60
15 cranks - 120, 110, 85, 100

Wet
5 cranks - 60,60,60,70
15 cranks - 130,115,90,105

These seem extremely low.... The car was dynoed by STM last summer at 228hp (mustang dyno).

Would this be head problems or ring?

 

need to do a leak down test to answer that question..

 

oh, Joy.....

 

Not the best, but hey 169k! So whats the issue, you just notcing this and you think its a prob? If the car is running well and your not looking to do something else to it--its fine. I don't know If would be modding it with what you have stated, but driving it, I don't see an issue.

 

I was starting to plan some mods, well at least a tune for what the previous owner put on it but now im not so sure. She runs fine so im not too concerned just wanted to know where to go next so that i can be aware of the problem and keep an eye on it

 

A tune isn't going to hurt anything--just don't think your going to bolt on another 60-70 hp and not see a potential degradation in condition. Good luck, have fun.
