Well, all things being equal, I think we need about 800. John and Sumner think I probably need more.
Now, that would be running exactly as before, with no changes. I'm hoping aero, along with a full bellypan, will allow us to run with less HP, because I think we'll struggle to get 800 on the dyno, and have the engine survive, let alone get that much to the ground.
We had problems getting the HP to the ground, and really saw little gains after the low 160's.I think the car was floating in the rear, so I have high hopes for the bellypan. Last year, the bellypan only covered the front 60% of the car.
I have no idea if all of this will get us the results we need, but if we fall short of our goals, it sure won't be for lack of trying!
