is my compression good to boost?
 

i just did a compression test and in cylinder #1 its 160. 2,3,and 4 are at 190. is it still okay to boost the greddy 15g at 12 pounds like this?? i keep getting mixed reviews. i double checked it, and its the same. no leaks, burned oil, and it runs like a champ.

ah its borderline. leakdown and see where the compression is going. if its not the rings then you should be fine.


my motor last year's compression was 190.190.120.190 and it ran 12s and handled 18 psi fine the day i took it apart. it was also sleeved and fully built and dyno tuned, so take that into consideration too
