Yes, with that prop and assuming there is some comparability between your 76x88 Cato and my 74x88 Performance prop, I would think you should get at least 5500 -5700 rpm. When I did my exhaust experiments, I found that a too restrictive (quite) exhaust definitely adversely impacted performance. Oil temp sounds a bit high for that OAT, but coolant temps look very good. Are you using the stock oil cooler and if so where is it located? I know you have a James Cowl so interested in finding out what locations do/don't work with the radiator and oil cooler.
