Perfect street/strip converter

You should be able to get a good unit for $500-700.

I think edge racing has a piece for 525ish. I know a couple of guys that have them. Andre is good to work with. Work well.
Lenny at Ultimate is really good, might be the high end of your range.
Lenny is a POS that doesn't stand behind his product when it fails immediately out of the box for 2 seperate reasons. Also most real converter companies laugh at using a 9.5, either run a 10 or use an 8......scam companies sell them because the cores are cheap. A-1 for me all the way and my car runs pretty close to what it should because of it and I also street drive it too.
