Fuel Burn Rate Of The Kruzza?

[Greg Mitchell]

Hey Sam,Can you give me some figures for your fuel burn rates at cruize.Tks,Mitch

Hi MitchMy GTG KRUZA Cruise G-762a) 1 up 65 Kts 4000 rpm, half tank of fuel 18 lts p/hb) 2 up 65 kts 4300 rpm, half tank of fuel 25 lts p/hNew variable cam engine GTG KRUZAa) 1 up 65 kts 3700 rpm, half tank of fuel 15 lts p/hb) 2 up 65 kts 4000 rpm, half tank of fuel 22 lts p/h Regards SamL.............

Cheers Sam, appreciated.Sam are you using a variable pitch prop? Is that what you mean by variable cam engine?Mitch.

Boy, its interesting to see what 300 revs mean to fuel burn.

Sam,Are you being set up??? ;D

"Sam are you using a variable pitch prop? Is that what you mean by variable cam engine?"Mitch,They are not using variable pitch props, but the new engine is variable cam.http://en.wikipedia.org/wiki/Variable_valve_timing

Thanks Graham,Just talked with Chopper and he advised the same. I shall check out the video.I have been told that a variable pitch prop can reduce fuel burn by up to 25%.Kym, I am not trying to set Sam up. Simply comparing his fuel burn figures against another breed of two place machines.Cheers,Mitch.

so are you supposed to be able to get a video of that honda head turning ? cause i cant, that"s really interesting thou . i always wondered how they did it.

Sorry gents, but been away with the family, so called long weekend.Hi Mitch Interested to know what you are comparing it to?Also interested in the performance fig comparison?I have now taken a squillion people for a fly in my KRUZA and Kym is one who can contest to the figures.I will always tell it the way it is because that is who I am. Regards SamL..............

Sam, do they both pull the same engine rpm at WOT?Regards, Aussie Paul.Sorry Paul you have lost me. What is WOT?

Regards SamL.............. Hey Mate how are you and the family, hope you enjoyed your time away."Sam I have a fellow who has enquired about a Golden/Turbo Golden and was a little taken back at the fuel burn rate of both, although I was told that a variable pitch prop installed reduces fuel burn by up to 25%. We are talking about 190 HP and 305 HP respectively.So my friend, definitely not trying to set you up or anyone else for that matter.I asked you for figures for your Kruzza range simply because I knew you of all people would have the facts on hand and give me the figures straight up.I"m bringing the Monarch to Temora next April, was hoping to catch up with you before that.Thanks for the info Sam. Mitch.

Thanks for the link Graham.They say Variable cams, can generally give an increase of 10% power and fuel savings.From Wikipedia on the Subaru version of variable cam.i-AVLSi-Active Valve Lift System (i-AVLS) is a version that supports variable valve lift. It includes 2 intake lift profiles depending on engine speeds. AVLS-equipped Subaru engines have 2 intake valves per cylinder, but AVLS only controls one of them, leaving the other in high-lift mode at all times.At low engine speeds, each of the two intake valves for a given cylinder run on a different camshaft profile (the engines are 4-valve per cylinder type). One valve is operated by a low-lift, low-duration lobe, while the other is actuated by a high-lift, high-duration lobe. This increases air speed causing a smooth idle, while at the same time promoting a swirl factor, increasing efficiency.At high speeds, the ECU (Engine Control Unit) computer signals a solenoid to let oil pressure move a pin which locks the two lobes together. This means at high speed both intake valves are effectively driven by the high-speed camshaft lobe. This increases high-RPM power due to increased valve lift, duration and overall timing.Cam locking is done by moving a pin with hydraulic pressure. As with other variable valve timing systems, it allows the engine to have a quiet low-speed operation with a smooth idle, while also using a camshaft lobe profile similar to "race cam" at high engine RPMs. "Looks good Sam.

Sam, do they both pull the same engine rpm at WOT?Regards, Aussie Paul.YES both are set for 5200 RPM Full Noise.
