Gang,
George is right. We do manufacture newly rewound coils. We started on this
project in 2000 or 2001. Jan is correct. It does get very expensive. We
have had our coils out there for 3 years, running well. I will write more
next week. We are hosting an RPA Flyin and I don't have time for a lengthy
reply this morning.
The price is $500 exchange.

Hi Brian as I was walking around Sun&Fun this year there was a vendor with
an M14P that had a single port fuel injection on it when I talked with the
vendor they said they were working on a computer controlled multi port fuel
injection system with computer controlled-electronic ignition she was sh
owing a coil over plug unit and a fuel-injector from a Toyota I believe.
Took a picture of the engine but not the vendor I thought it was Barrett bu
t couldn't find any info on their web site and fired off an e-mail to find
out, (attached). Anyway like you-I think computer controlled fuel and spa
rk is the way to go, I mean are-ANY auto's being built with distributor a
nd points today? I don't think so.-=0A-=0A=0AFrom: BPA <BPA@BPAENGINES.

1 5:16 PM=0ASubject: RE: M14 P=0A=0A-=0AHi Bill,=0A-=0AWe have made sev
eral improvements to the M14 series engines. Starting with the fuel injecti
on we have a single port injection system. We are also working on a better
fuel nozzle that will allow for optimum fuel atomization. This is a kind of
slow process as it consists of not only the proper spray pattern but also
the location or angle that the nozzles is pointed to get the right atomizat
ion.=0A-=0AWe have changed the piston and ring package from original desi
gn to drastically reduce oil consumption. We have pistons forged both in fl
at top standard compression and domed high compression. Our ring package co
nsists of 2 compression rings and 1 oil control ring versus the Russian des
ign of 3 compression, 1 oil control and one scraper ring. Oil consumption h
as been dropped to as much as 1 quart in 8-10 hours. Several engines have t
hese new rings and pistons and to date have had no knowledge of high rate o
f oil consumption.=0A-=0AWe have a modification that we do to the reducti
on gears to aid in cooler oil temps by as much as 15 degrees F. =0A-=0AOt
her repairs are within the engine where previously no repair procedures wer
e available such as the nose case seal that controls oil pressure to the pr
op governor. Repair of the exhaust port flange is now available as are reco
nditioned exhaust valves.=0A-=0AWe are to be testing the proto-type elect
ronic ignition sometime late in November. This will be a full authoritive s
ystem with built in alternators to supply their own power.=0A-=0AWe also
are in test with a prop manufacturer from Italythat has replacement blades
for the Russian hub.=0A-=0AIt seems that there are so many repair process
es that until now have never been developed or are not known about. Before

There are lots of different injectors made. The car manufacturers don't make
them, they just OEM them from the likes of Bosch or Denso. Lots of different
injectors out there. You spec the fuel rail pressure, max flow, injector
volume, peak-and-hold (low impedance) or saturation (high impedance) coils
(peak-and-hold works better on high RPM engines), block or sequential
injection, and then pick the one you like best.

No, and now that I have had a chance to build and tune one all I can say is
that I completely understand why the automotive industry has gone this way.
I used to be really good at tuning Webber carbs but I can do things with EFI
that I only dreamed about back then. I won't go back and mess with
carburetors, distributors, points, or magnetos again if I can avoid it. Even
in older cars it is dirt-simple to retrofit. Why not our airplanes?
And if you want to run lean-of-peak for cruise efficiency, you can trim the
mixture for each cylinder independently and even have different trim at
different MAPs and RPMs to account for differences in airflow volume at
different flow velocities and induction tuning. The funny thing now is that
the only thing that is really limiting us is the fact that avgas still has
lead in it, making it difficult to keep from killing the wide-band O2 sensor
needed to do good tuning.
By retrofitting a throttle position sensor to an existing pressure carb or
Airflow Performance throttle body, and then adding a crank and cam position
sensor (replace one magneto), you can then easily add electronic ignition
and fuel injection while leaving the carb and 2nd magneto as backup. I see
from the note you got back from BPA they are even thinking of separate
alternators. I think that is a bit of overkill as one can achieve the
requisite electrical system reliability without that (I suspect they are
catering to FAA braindamage), but I would like to see at least two
alternators in case one decided to eliminate the magnetos completely.
The funny thing is, people get so worried about the engine quitting if they
lose the electrical system that they forget that our engines have lots of
other single-points-of-failure. I would be willing to bet one could retrofit
to EFI and electronic ignition and raise the MTBF even without a dedicated
electrical system for the EFI and ignition.

| Subject: | Want to buy: M14P Propeller! |
Please contact me if you have a serviceable and complete M14P Prop!
Hoping to find an MTV-9-250/260 prop, perhaps with a matching governor.
or even a V530 Prop hub - must be in excellent condition.

I'll vouch for Jills coils. I have two in my mags now for some 3 years and
they are doing fine. I do want to try a electronic ignition though and I
am looking at one I saw at OSH this year.
