Hey ,
I was just wondering some opinions on how much et or mph could be lost when a car is "over" converted.
I have a zz 502 in a nova, and can powerbrake to 3200, probably flashes 42-4500 rpm, way to much, but all I have for right now.

Thats not to much stall really. If you could get it to hook it would leave HARD.

Got a timeslip to post? Are you driving thru the convertor?

That's not too high. My wifes camaro runs 4700 on the Tbrake and flashes to 5400. Street driving is OK as long as you dont live in the hills! We've tried 2 other tighter converters that lost et but gained a little MPH, we went for et and wheels up launches! BTW, that's with the ZZ502 too.
