Performance

HI Guys,

I've added a few more pictures of the air boxes dad and I made for the original RV cowl. We've been flying with the big rads and our air boxes and they are awesome! We actually had to close the cowl flap to half open (about 3 inches down) on our climb out yesterday in 77F OAT because we ran too cool.

We checked our top speed yesterday with the cowl flap closed at WOT and 2500 on the prop. Our coolant temp settled at 205F and oil at 200F at 3000Ft we indicated 175 KTAS (201mph) two ways. Full power cruise is not a problem at all.

RV6 H6 MT pro (big rads, interal muffler drilled baffles, orginal ECU and origina RV cowl) 93 hours.

Economy cruise power at 9000', OAT 47, 1800 prop RPM, Oil 200F, Coolant 183F, Gearbox 162F, Fuel Flow 5.6 gph and 162 MPH. The TAS and gph are very close but not verified. 460 nm, flight time 3+21, fuel used 19.9 gallons with 0-5 knot tailwind. Thanks for an enjoyable and educational day yesterday.

GRAPH SHOW THE PERFORMANCE OF THE BRAND NEW 2008 and 2009 3.6l ENGINE AND ALSO THE 3.0L ENGINE

The new 3.6L engine can produce more HP and torque at a lower RPM. For instance, 200 HP is available way down at 4300 RPM with torque close to 500 ftlb at the propeller. (Using the 2.02 /1 ratio reduction drive and 2150 propeller RPM) This new engine also has reduced compression and can be flown using Low test Auto fuel.

LOW VIBRATIONS

The measurements on the Eggenfellner Subaru had very low stress level and therefore we do not expect to have any problems with the 200 hp and the gear reduction.

With best regards,

GLASTAR ECONOMY (PERFORMANCE)

Subies and wanabe's,

Yesterday we had a break in the weather (snow & high winds) so we had a group gaggle fly off the island for lunch. We had 3 Super Cubs, 1 Cessna 120 and my E-Sube powered GlaStar. Flying formation with this gaggle I had to reduce power to 3000 eng. rpm/1650 prop. OAT was 25 deg. so they were all dressed in insulated coveralls, heavy coats, stocking caps etc. trying to keep from freezing. Meanwhile I was very comfortable in a light shirt basking in the heat from my hot coolant multi fan speed cockpit heater/defroster. The best part was, they were burning 8 gph of 100 LL while I was only burning 2.3 GPH of auto fuel !!!

We all had a great lunch and departed for the island. One of the pilot/passengers in one of the Super Cubs rode back with me. He said going from the Super Cub/Lyc. to the GlaStar/Subaru was like being beamed 100 years into the future. He must be a Star Wars fan :>))

H-6 FROM THE INSIDE WITH 7 MAIN BEARINGS

This engine is truly built like a tank. look at the 7 individual webs running through the case for support.

GET A RIDE (The TOTAL performance is so much more than speed)
Hi All,
I am building an RV7 at the same airport as Robert Paisley (CCB) and have been fortunate enough to have ridden with him many times. I had taken my first flight in an RV in Robert's plane. I was amazed at just how easy to operate his plane was with the 2.5L flat four Subaru. I then was with him when we flew faster than Dan Checkoway's RV7. At that time Robert had the STi motor and I was even more impressed with this engine. Last week I got my first ride with the new H6 motor. The first thing I noticed was how smooth the engine was. Its AMAZING! You have never felt anything like it in a piston airplane. If any of you lurkers are on the fence take my word and get a ride, you'll be hooked.
