Belted Air Power Chevy V6 ...Indirect Update

[DanH]

<<i just am interested in BAP and would like to get more info>>

No problem Jeff. Fact is, so would I. Apparently there are no flying BAP owners present and willing to participate.

At least 90% of the issues discussed here apply to a BAP drive. The laws of physics apply equally to all.

What info would you like to have?

[jeff122670]

well, basically i would like to know if people are having problems with the system, how are issues such as cooling, etc, etc holding up and in general, how do they like the system.

also, which prop is best suited for it...

do you have any gouge on it?

thanks

Jeff

Looking at the number of engines available over 130 hp it soon becomes a very short list on what is available other than GA
type flat engines.
The Chevy V6 with Belted Air Power in the RV 6 is a known comparison to compare with and I asked Jess Meyers what he thought
was an honest opinion as an attractive alternative.
The RV Jess flies, according to him is no masterpiece, and was not a quick build kit either. Built in 3 places and assembled
in 1 made it a very interesting challenge to put together and required some clean up of the aerodynamic areas.

On performance do not underestimate this combination. Jess can depart North Las Vegas on 100 degree day at gross of 1750 and
climb out at 900 to 1000 ft per minute.
Sure, we are told ?most RV`s will do that. ?
When you factor in the field elevation at 5000msl this certainly grabs everybody?s attention.

Flying in the real world it is about fuel usage not just at cruise but overall from start to landing. Jess can select a tank,
start the engine, taxi out, takeoff, fly a 150 mile flight, return and top off the tank singular.
The flight usage from start to top off used 7.5 gal per hour.
With say a Lyc the take off and climb to altitude will burn as much as the next hour in flight. Think about it???..on today?s
cost of fuel??.

On a go around as long as the airplane is above 70 knots indicated and throttle is pushed to the wall it is instant power.
Gives you a kick in the seat and it is up and roaring. With a Warp/Drive prop we can enter the pattern at 180 mph
indicated, retard the throttle and have breaking power such as a Ground Fine in a turbine, advancing the throttle we
can go 0 thrust to glide.
This engine package has a lot of advantages. You can go straight to 10 grand , chop the throttle and head straight back down
if you want and you will not thermal shock the cylinders. On the RV the cruise can be a leisurely 140 ind to 180 ind .
The Chevy will take on a tuned Lyc to 8K no problem. The Lync may slightly pull away which is still saying something.
Jess frequently flies for 160 mph with an rpm of around 3600 to 3700 rpm with a fuel burn of 7.5 us gal per hour.

Jess has been testing the new Vari Prop which will suit the Chev V6 conversion and our engine packages. Initial testing
showed over 1500 ft per minute climb out.
An economy flight revealed with the engine back to 2500 rpm and 20 inches for 130 knots indicated WITH a fuel burn of 3 galls
per hour says it all.

Jess runs the all cast iron engine.
Performance and weight usually go hand in hand so with alloy heads and alloy block options our performance can only get
better.

FYI, the field elevation at Las Vegas is 2205.

I've seen Jess's setup and almost bought in when I was based at KVGT.
I was impressed with it and the cost.

just checking in to see if anyone is flying with the Belted Air unit yet...
