The total output was 950 rwhp.

A little bit of water injection can help. Water(H2O) has a high speciofic heat capacity, which means it can absorb a lot of heat.
A small amount of the combustion heat is used to vapourize the liquid water into a gas, steam.
You will also have a VERY clean combustion chamber as a result.
You can use a pressure switch to turn the water injection on and off, so it will only activate at the exact time you need it.

Just an idea.

Goodluck, thats a nice setup you have.
