Ive said it before..my favorite videos are the mechanical, building, designing stuff ones...love the flying but really like getting to the flying the most. Cant wait to see the hanger come alive videos...I bet it will be a great workshop also...your dad is amazing and you are a very fortunate son. As old as Im getting my very favorite thing is working with and teaching my son.

what a great comment Lee, thanks for that. I am very much looking forward to setting up the hanger with some equipment and tools and increasing capabillity of what can be done in the hanger. some things will still need to go to the shop- which is fine as it's close by.. but more will get done in the new hanger than the current hanger. thanks again!

Good job of retrofitted better design. I have a 100 Hp ULS that should have the intake upgraded to eliminate the floppy Bings. I have to support carbs with AC Aluminum flange to Bing bell mounted supports. They shake at the old style swung out manifold design and break those hard rubber manifold mounts. Wish I had a bolt on inner cooled tiny turbo naturally aspirated unit to be more up to date. Could use the upper altitude air but don’t need too much more Hp. Gonna change all motor mounts and may put a newer ULS motor on. Mine takes lots of starter time to get it going,,, on new carbs. Thanks for your educational shows and out door get away films… I live in Wa state above the Olympic Mtns and your Idaho films are the best.

Thanks for the comment! The bings do have their annoyances for sure! I don't miss that much. The fuel injection setup is not cheap, but it's probably the best product edge offers overall. I really, hated the carbs on the 914... the egt spread is noticeably worse on a 914 than the 912. It was terrible. Do you have the rotax intake manifold? I found one cheap on ebay that I put on my old big bore 912 on the last plane. And then you can make brackets that mount to it, and it supports the carbs from the inlet side. Also allows for colder air into the motor... just a thought. Buying one new is super expensive, but if you find a used one, might be a nice little upgrade and also help suppor the carbs. Also, JBM, (I think is the brand name) makes upgraded manifold to carb sockets... maybe those would help?

@@GravityKnightFlying thanks for the input and naming options. I thought I had none so I designed and machine support brackets that fatigued to failure in less than 100 hr which allowed rubber manifolds to fail within 20 hr of flight. I even fabbed AC Aluminum intake mounts but have yet to try out in fear of direct translation of high frequency damage to carbs. My mount on the intake is on the soft side of the rubber manifolds and the to the carbs, limiting translation of fatigue energy to the carb. I bought flatter K&N filters to minimize moment arms for fatigue to rubber manifolds but this helps minimally. I inspect the intake system flight to flight. BTW, the springs to Bings never helped reduce the leverage on those manifolds.I may look for something used on the injection systems someday and may try reversing the main intakes side to side to set the swing inward like newer 912 set ups. That few inches of radius swing must add lots of force at 5200 rpm. Keep posting off grid TO/Landing, it supplements my loss of flying due to mechanical work. I watch them over and over at times. I like to watch the Maule Guy also!

@GravityKnightFlying2 жыл бұрын
Not really my cup of tea. I'll explain why. Cool event, nothing against the event at all. Came from a racing background with cars, so I can appreciate that. But what I have noticed is that to be competitive, you need 300hp, and you need to work your plane very hard. Nothing wrong with not winning, but no matter what, it seems a person is going to push their plane hard to put in the best time you can. That isn't to say it can't be done smoothly, and not overly destructive.. but that type of racing does generally seem to be hard on an airplane. Something to consider anyway. I do typically prefer to be in a rush when doing technical type flying as well, so it feels a little off to be racing to stuff it in and land etc. Again nothing against it, I'm sure its a total blast, and I love watching Steve put on a good show. If I had the money to have a dedicated, high HP stol drag plane I could just beat the snot out of, I would be there. But I do work hard to keep this bird clean and in tip top shape both visually and mechanically so that it will perform when needed, and hopefully hold a good resale value etc. Great question though

Make a custom flange via CNC, you'll want the wastegate completely divorced from the turbine flow for best results. Trust me. That's close to the same IWG setup as my STi.
@GravityKnightFlying2 жыл бұрын
The divorced design is better as you said, but one thing to keep in mind, this motor only produces around 140hp, and the exhaust is dumping into a 3.5" pipe right out of the turbine housing. There would potentially be slightly more efficient flow if they were separated due to turbulence, but it's a pretty un-restricted outlet for the power level. Probably be hard to notice any difference. Turbo size is overkill in other words for the power, but also allows maintaining power up very high at higher pressure ratios, and it's more fuel efficient to breathe through that larger turbine. The servo controlled wastegate does allow the potentially to partially open the gate in cruise to allow more exhaust around the turbine which also increases efficiency. Pretty cool stuff. By the way, I came from the car world, subarus before evos.. I had a wrx wagon I swapped a 6 speed into out of an 07 Sti. Set a cheesy internet record that still might stand? (11.7 and 119 on a stock block 2.0 motor at high altitude). One of the first to put a holset turbo on an EJ motor. That motor let go at 178k miles after I turned it up to see just how far it would go. Broke a rod before the 1/8 mile and coasted in at something like a 12.2. It was on a pass. Did a budget built 2.0, put an HX40 with a BEP housing on it, and trapped 130 Fun car, but got high strung enough it ended up being a lot of headaches. This was 10-11 years ago or something like that. Cheers -Todd

@@GravityKnightFlying Todd, great to hear! Been working on Subarus since late 2005 when I picked up my 2002 WRX. Did a 2005 STi swap to it while in Germany when a friend's wife rolled their car. Did a bunch of mods to it, cracked 400whp. Was going to turn it into an 818C kit car, but had some financial issues that took precedence. Ended up parting out the cat and rebuilding the shell with the remnants of a friend's rolled WRX for him. Bought my buddy's 2010 STi that he did a 207 swap on two years ago and been working on fixing some questionable things he did ever since. Haven't had it to the track yet, been tuning for e85 and sorting some fueling issues out when able. Owned 4 other Subarus as well. I'll be out in CO for Christmas, would be cool to meet you!

What are the turbo specs, eg turbine/ compressor Inducer, exducer? and AR also. Im using a 1470CC Suzuki engine at 5000 rpm. For high altitude I am using a twin scroll housing with a merge valve. So all 4 ports go into one half of the turbine wheel and then as soon as it makes 15 kpa of boost the merge valve starts to open splitting the 4 cylinders into 2+2. It is for a high altitude aircraft and the turbo is my air supply so had the same concern. This way it spools very quickly, but is not restrictive at 1 bar of boost. I am using a hybrid GBC 22-350 turbine, and GBC17-250 compressor.

Why not just go with external wastegate?
@GravityKnightFlying2 жыл бұрын
Good Q...Lot more control with the servo controlling the gate via cable. Can open the gate during cruise for a nice increase in efficiency. Also allows for altitude compensation to maintain overall manifold pressure as you go up. Now with the electric external gates like from turbosmart the same thing *could* be done with an external gate, but not sure anyone has setup this ECU to work with that gate yet (probably could be done as it has some output channels, like the one being utilized for the external gate, but those new electric gates didn't exist when this setup was built).
@Mike-012342 жыл бұрын
@@GravityKnightFlying The external gate I used in a drag race 90s mustang 10" tire about 10-12 years ago had turbonetics gate it was controlled by a pressure regulator between the turbo inlet and output sides then the regulator the controller was aftermarket I just used a 5 position rotating switch set the power output which would lock in my boost pressure and automatically adjust to altitude via the regulator. If I was street driving I set it to 5 PSI gave me about 450HP to the wheels at the track using racing fuel I could get 18-19PSI I hit about 820HP with 70MM turbo. I never used the computer to control the wastegate the Fuel injection computer system was an AEM used it was all based off manifold pressure with linier type fuel maps more pressure. My limits were based on the fuel type pump gas I never tried more then 5 psi was more then enough power on the street anyway as you know with turbo engines doesn't take much detonation to explode them even with custom forged pistons. All you need is a boost controller and wastegate they make electronic stand alone ones also. The regulator will take into account the altitude pressure on the inlet side. The electronic wastegate controllers have been around since the mid 2000's. If your ECU fuel maps can adjust for boost it shouldn't be a problem I can't see why it wouldn't be because currently the mechanical system you have it's not controlling anyway. The only factor I could see is finding a small enough external wastegate that would work for you most of the ones sold for drag racing for big engines you would not want an external gate that it too big want something that is matched for the size of the engine. Wonder if you need a blow off valve on an aviation engine maybe not since RPM isn't change quickly it does keep the turbo spooled when cut the throttle maybe for stol competitions making lot of power changes need one?
