Yep amazing what those early aviation guys got up too ... haven't read the book but will look out for it .... Would be great if some new interest was brought to the TR1 wing .. but haven't u just build a lite wing ..!?

I'm using P-mags for ignition which have spark advance, but it's not as good as you can do with a knock sensor and digital fuel injection. With light winds and fully cleaned up my plane just might be able to do make it to Hawaii. After you make Hawaii then getting down to Australia is "easy". Reminds me of the book called The Sky Beyond by an Australian named Gordon Taylor. It's about the flying in Australia and the south pacific in the 20s and 30s. Imagine landing a Catalina on the lagoon in Bora Bora in the 1930s. Great book.

I looked at my Subaru engine weights again ... 2.5 sti engine running non turbo .. ( turbo 270 hp ... but looking for derated at close to 200 hp ) Engine long block 80kg Engine exhaust x2 4kg Alternator 70amp 5kg Engine mounts 3kg Intake/coil/leads/TB 7kg Redrive 1:1.82 ratio 26kg Total .......... 125kg (275 lbs Belly Scoop Radiator ... ?kg Plumbing ........................ ?kg Water coolant...................?kg So pretty line ball with the IO 360 by the looks ..?! Cost well ..... Auto conversions can cost anything ...cost Larry his plane ... sob ...cost me a forced landing and some busted parts ... has cost others much more hey ..? BUT .... If u find the rite engine builder (finally i think i have ) who specializes in only my engine (subaru) type and is fair dinkum ( not blowing smoke) ... well not much money ... I'v managed to track down bout the best subaru man in Melbourne ...$ 2-3 K for engine preparation (blue printing crank clearances,forged pistons ,line boring ,s/s x-rayed valves , etc etc .. i supplied the block and core heads and Delta cams .. His short block (factory new) price $1600 .. ( bugger i already paid $2000 for the same factory block grr ..!?) Haven't settled on engine management ... has to be not subaru though (limp mode etc etc ..) The engine builder is looking at SDS and Tracy Cook etc ... Running knock sensors allows timing rite up to Peck Power .. and without it the engine is just missing out on available power ...! Redrives ... are a real headache i think .... Harmonics vary with each individual engine type combo ... so danger there ... Electric's ...well i didn't build the plane so there is gaps in my knowledge how some things are set up .. i have two 17 amp hr (34 amp hrs)Batteries and two Buss's ..engine runs on either or both !! .. and will run on the Alternator alone ..!!! ...not as good as running Mags ...but ur Mag timing is set off for detonation safety ... so loosing power hey !! Anyway ...blowed if i know ... i specially DON'T like getting milked by the certified engine so and so's ...!!! Engine guy thinks i'm a little conservative ... ! but a turbo is a possibility in the future ..far off though ...( car turbo rotors are not suitable for aero use though ) So ..as Bill says ...not for everybody ..!! Cheers Graham Ps Have friends coming to CA in 3 wks time ..wish it was me ..sob ..! . . ----- Original Message ----- From: Scott Stearns To: kis-list@matronics.com Sent: Tuesday, January 18, 2011 7:26 PM Subject: Re: KIS-List: Engines Hi Graham, I don't mind using a relief bottle. Also going multiple legs without refueling can be useful. For instance I was flying down in the Bahamas over the summer and it would have saved a good amount of money to have been able to fill up with $4 gallon gas in the US and not have to buy the $6+/gallon gas in the Bahamas. Basically I can do two 3 hour legs and land with full main tanks (40 gallons), but I would have to do it solo. For instance I'll flying from California to Florida at some point. Right now there are some airports in texas that are selling 100LL for $3.50/gallon. I could fly from Texas to Florida and half way back with the cheap gas even if I wanted to stop a couple times. Good luck with the subaru engine. What kind of power are you expecting and at what cost? What kind of electical system are you running to have backup power for the engine computer?

Good thinking on being able to hold HP up high ..have to wonder about 'watering the horse' though with all that fuel endurance .... My 'endurance' due bladder ..!!! is only a couple of hrs though ..!!! On my engine build ... well the engine is in some ways the easy part and i do like water for head cooling etc ...but the Redrive with an auto conversion is much more problematic .. !!! Should come in under 300lbs ... will re total the weights this week .. Hey ..Bill Schertz ...how bout chiming in with some back up with ur Cruiser .... it has a Rotary rite ..or ..or ..?
