The Saito is probably heavier than the GP so may be able to remove some weight and the forward moment will increase so may be able to remove excess weight.
I don’t see a problem running the engine inverted, the FG60 ran perfectly well on the stand like that, but never tried it on a plane. I would be tempted to baffle the engine better and have it mounted in the upright position. Baffling on these things is paramount. Creating negative pressure behind the engine whether air exit is top, bottom, middle doesn’t matter..
Agree, baffles a must. The prop fan/hub by Ziroli is also an interesting way to go...like on the real plane. On my Zero I cut the cowl flaps off and re-positioned them more open. Made a difference in temps. Unfortunately not possible on FW 190. I've asked my Saito guru Ray English to test running the engine upside down. Breather nipple challenge was first thought. Redoing a Keleo exhaust is the second thought.
