i have a d16y8 running 9lbs on a jackson racing supercharger.

gears 1 and 2 are strong and pleasing but it drops off after that. if i lose a race to a turbo car its almost always them catching up on the high end and passing. i need more in 3rd and 4th.

so my question is, without a rebuild what will increase my high end the best.

should i go with a cam lobed for a supercharged setup or go with a 35 shot of nitrous to run in 3rd and 4th.

initial costs will be about the same for both setups, but nitrous i'll have to refill, so in the long run will be more costly.


advice?
