Who designed and made this PSRU? Moving the prop shaft up would be a big
help in keeping the engine totally enclosed in the cowl without bumps.

Not really. You gain mostly useless space on the top of the engine while
losing valuable volume under the engine for the cooling system.

It is easy to mount the alternator on the cool side of the engine and cut
down the 2nd gen water pump. If you are using an RX8 engine there is no need
to cut down the water pump as it is already low profile.

There are a very few airplanes where space at the top of the engine under
the cowl is marginal. The KIS Cruiser  is one of them and so are some
versions of the Lancair. I forgot what airplane you are building.
I may have a 3D layout for it so I could check your fit and space
requirements.

I"ve got the Thorp T18 and I just ordered the six port from Australia.
Maintaining the thrust line with the 5% down and 3% right, as called for in
the plans, moves the rear of the engine close to the top of the cowl and the
exhaust close to the left side. The prop shaft is just 1/2 inch right of
center in the plans. Karibian

Yes I see. That will be a tight sqeeze.
Your going to wind up with cowl modifications.
