...In every phase of flight it is a really great improvement in performance and in cylinder temperatures! Last Year I bought a Turbo Plus intercooler kit from Jeff Shapiro for my Mooney M20K 231. First, the delivery was very fast and second he gave me a special price for me as member of MAPA. When I unpacked the kit, I was very happy about the really great quality of all the parts. Welding, tolerances and so on. I installed the kit in two days and it was a great pleasure to do. The fiberglass work at the cowling is also very easy, but needs a little bit of trim. When I had finished all that work and the final adjustment of the TCM injection system, I went flying to see what it will improve. First was, that the intake air immediately cooled down about 30 deg. Celsius in the takeoff run. I operate my Mooney from a 750 meter asphalt strip. After takeoff, in the climb it was cooling by 45 deg. Celsius and raised to 55 deg. in higher altitudes. I think the NACA duct is at the optimum position. Much better and more efficient than by the 252 model, because it gets directly cool air from the outside and not via the cylinders inside the cowling on the right side in the engine compartment. In cruise I have now much cooler cylinder head temperatures , mostly about 320 deg. Fahrenheit with 75-85 percent of power. I was flying now for approx. 9 month with the intercooler and in every phase of flight it is a really great improvement in performance and in cylinder temperatures!! So finally I think that is one of the best mods for a 231 model. Regards, Alex Haselmann D-EMLL Mooney M20K

We want to know how to correlate the cockpit intercooler readings to manifold pressure guage in the cockpit
