The cooling-baffle might not fit
"Unknown vibrations" not yet tested, compared to a IO 360
The MT-guys don't feel to happy with this, however would supply the prop
The Raven system is not known yet in Germany??
The exhaust would need some mod's?
What kind of mount would one need for the engine?
The IO 375 weighs 14 lbs less than the "original" 360 lycoming and produces significantly more power, so the paper looks good for the beginning.
And last, I'm eyeballing the James cowl. Has anyone experience with that one?
Looking forward to hearing from y'all

Hi,
I'm a RV8 builder but I think the informations I have could be right for a 7.
Van's baffles need modification to fit the conical fin on the cylinder (fin diameter increase from the root to the cylinder head). I contacted Bart at Aerosport Power and that is what he recommends.
Vetterman exhaust produces at least a 4 in 4 and a crossover exhaust for the cold air sump mounted on the IO-375 (the dual heat muff on the 4 in 4 is a plus).
I also have a James cowl, there is not interference between the cowl and engine.
The engine mount is the same as the IO-360 M1B ( I can't remember if it is the DI or the DII but someone else will tell you)
The Whirlwind guys think it is a good engine
I weighted the IO-375 M1S (w/o : prop extension, mags (I use dual plasmaIII) alternator) and I found 125,9 Kg <=> 277lb which is pretty light. It is a plus on the 8 which is generally nose heavy.
I don't have a raven but the christen fit well.
There is a mixture and throttle bracket mod to do ( I can send you pics if needed) but nothing difficult.
But as my 8 isn't flying yet I can't report any review for the moment.
Hoping this will help you
Have a good evening.
