Helping a buddy work out squawks on new installation in a -7A. The engine is an ECI IO-360, Precision Airmotive Silverhawk FI, 9:1 pistons, dual P-mags. Oil cooler is Aero Classics from Van's mounted on cylinder #4. The engine also has the cam lubrication holes.
What should fuel pressure range be on this fuel injected system? The Dynon is showing about 15 PSI with the electric boost pump on.
Also having problems with oil temps (230+). I've read most of the other threads and most seem to say change to the SW oil cooler, put louvres in or cut out some of the cowl exit to solve. We have already replaced the vernatherm. The baffling is sealed well. The air inlet ramps on the top at the front of the cowl are sealed to prevent leakage "over the top". CHT's are in the 360 - 400 range (#4 the hottest at 400).
The problem is, I have the exact same setup except I am a carbureted XP-360, 8.5:1, mags. I have not seen oil temps over 190 since day one. Our side by side installations look identical.
Why are his temps so high? Do we need to make the cowl mods, get the more expensive SW cooler (8406R)?
Thanks!
