Not sure about you generator head, but some have very husky bearings
and will work well belt driven. If you do that, I would look at the
multiple v belts used on cars and get the pulleys from the local scrap
yard. With a belt drive you can drive the generator at something other
than the engine speed.

The generator head I'm looking at is designed for 1800 rpm and
requires a minimum 50 shaft horsepower. A car engine with a modified
cruise control (use as governor) will fill that bill easily.

I don't trust belts much.

Your Ford escort has 50 bhp @ 1800 rpm?

After chatting with my mechanic friend looks like I'm going to go with
an inline 6 motor since the escort motor will only develop around 25
hp at 1800 rpm unless I put a different cam in it. (Which I don't want
to fudge with). The 6 cylinder should develop 45 plus hp at 1800 rpm.



I cannot help but ask, what is the application that requires your
setup to produce 25 kW. Why not choose some lower power output and
have a lot less problems? If you choose say 10-12 kW output, you can get
away with much smaller, cheaper engines, use less fuel, have more
flexibility with choices of couplings etc. The cost is also going to
be lower.

I believe those ST heads are available in 10 and 15 kW variants.

10 kW is adequate for running a house during an outage, and will even
drive central AC nicely, unless you live in a huge mansion. My house
is about 5,000 square feet and uses an approximately 7 kW central AC.

Well, I can buy a new 22kw generator head for 650.00 or a 15 kw for
450.00. I can actually buy a complete, running car (for the motor) for
100.00 from a friend which is cheaper than an air cooled motor.

I'm not worried about the fuel economy since I'll only run it once in
a while for perhaps 8 hours.

I figure I can buy the parts and assemble a 22kw generator unit for
1000.00 or a 15 kw generator for 800.00. I'd rather have the larger
unit.
