ah, none of mine would be of ANY use to you. that kinda power is the reason i switched to the one i have now. i think the next best one i had stopped being effective at ~400 at the motor. i'm well over 500 at the motor now, and if you're talking between 500 and 600, you'll just end up in the same boat as me.

for what it's worth.. i had a hard time finding a MAF that could stand up to the kinda power i was making. even the 700hp rated models tell you 400-500 if you're supercharged. although at the time, i wasnt looking hard on the internet, which i'm sure made things 1000 times harder to find..

i dont have AIM on anything but my desktop at home, so i'm not on it much, but i'll add you to that list though.
