climb enhancements

I would be interested in an aftermarket turbonormalization if an STC was available.This would help in climb(high and hot days) and speed at altitude.

With the comments about progressive decease in climb performance on high density altitude days, I wonder about the possibility at increasing RPM for takeoff and initial climb to 2800 RPM(approx.210hp)The engine has been used in higher HP applications but I wonder about additional cooling problems. Any thoughts or comments?
