my original plans on my build was a 600hp Street car, ive since decided to go Track only and go for closer to 800whp, my ? is will the FMIC i have not be enough or do i have to go bigger ??

750-hp 31 1/2 L x 10 5/8 H x 3 1/2 D 2 3/4

 

possibly look into an air to water setup? http://www.precisionturbo.net/...=3052

 

Here are the HP ratings we got from the Precision catalog. Prices deleted per HT Policy. I've highlighted the one that I believe is closest to your dimensions. Which will support 750hp. Hope this helps!
