Starters weigh 7 pounds so there is six pounds right there.
Your intake weights are too high. I would say 5 pounds is more like it.
Oil is lighter than coolant so save three pounds.
No way 20 pounds for a constant speed prop. More like 40 or 50.
Way too much for motor mounts. 15 pounds apiece.

25 lb per engine, that is really good is 50 lb less. Mr. Lamar how much is
lots of money $1,000 or 2,000?  I know I can drop the weight some more. The
engine mount will be only 1 to hold the 2  engines, may be less than 40lb,
have not make it yet. the constant speed prop is a electrical variable pitch
composite propeller, don't remember really good but it's on 20's lb.

I think the rear aluminum housing is around $1200. Could be wrong you
need to call Jim at Racing Beat.
