I assume you have one (or 2) of the 787 engines?
They are already putting out 110 hp. Just find the right impeller, swap in a new wear ring, and it should be plenty fast.
Do too many mods to the engine and you will start to impact engine life-span and reliability.
Personally, I have a new 787 in my challenger and skat-trak swirl impeller, and I like the way it runs. Plus, with only 20 hours on the engine, I have peace of mind that it will get me home everytime out for the next few years.
