Oh and as you can see in my sig, it's the high output engine with the nv5600 and the 13 inch flywheel/clutch
So with the upgrades in my sig (150hp injectors and an edge ez) plus a super b special, I won't be over 400, will I? I'd rather stick with a single because of price but if that is too much power, I guess I will need a dual.It all depends on how much power you want to make. If you want 400 HP don't do a dual disc. If you want 500 you should probably start looking for a dual. If you want over 5 you need a dual. But if you are staying in the 400-425 HP range there is no need for a dual. A single will hold up just fine:thumbsup:
