Well, at 1600 or so where the car launches, I have less than 200 ft lbs and probably around 100 hp at the wheels.
Were hoping to footbrake to around 3000 and flash to 3500 or more.
That puts me closer to 400 or more ft/lbs at the wheels. I think it will 60' just fine.
Converter will help but it will not fix all your issues.
Keep the Boss intake and put some more gear in the car.
