Currently you can produce about 500 hp from a Coyote with headers, ram air and a tune.
look to add a supercharger to produce more HP coyote makes a SC crate engine with 9.5 compression We are using the 11.1 compression so you can adjust the boost down and tame it... or you can boost as seen below.
FYI you can always start with the 11.1 motor and add supercharger later (which is what i plan to do with my build now) tremec 600 3.64 gears or you can go with 3.91
