I voted 300-400 because my goal is 350-375 eventually. At that power level, i'd be in the 11's which is plenty to fluck with a lot of cars in a straight line from a dig or from a roll. That power would also be the limits of that largest DOTR/slicks i could fit on my car without going widebody/flares.
Not to mention that would give me a power to weight ratio of about 6.5:1...... thats flucking MOVING.
