I am thinking I hear spark knock, but can't really tell for sure because my exhaust is a little loud and my supercharger makes some noise. I have a 97 stage 3 Roush (i know they didnt make em) with a 2002 GT motor in it. It has a pulley on it and it makes about 9 psi. I don't think its been tuned but how can I tell? Thanks, i really don't want to blow up another motor.
1997 supercharger with spark knock help!
