Looking at doing something, Nitrous seems cheap and easy but 100$ here in Ontario to fill 3 lb bottle seems costly over time. Maybe add up to 5000$ a Supercharger kit costs from ulmer racing. I love my apex and it is plenty fast, i just want a shot here and there when dragging my buddies to secure a lead! Any opinions would be appreciated will install either kit i decide on myself father is a master mechanic works on cars, atv, snowmobile, motorcycles and boats so that cost is gone. I guess I'm just trying to see what the most cost efficient for the power/reliability. If i do supercharger I will probably only do 5psi to be close to 200hp around that because i want to keep the sled where it is in term of clutch and drive gears. I have ulmer stage 2 clutch kit and carbon drive shaft. Oh and last comment I'm in favor of nitrous because i choose when to shoot it so my sled will not suffer fuel mileage unless I want it to. seems to me Nitrous is the way to go for what i want.
