Tire question

What is the trap rpm? A 750DP is a lot to swallow below 2K. Perhaps change the launch technique so you dont go way into the secondaries until the tach climbs to 3500. If the trap rpm is below 5800 I'd look at trying a 650DP with the choke removed. It will be snappier even later with a real convertor. You may also try going up as high as 38° total.
