Viking Aircraft Engines What is your altitude threshold for full hp? How high can the turbo maintain 195hp. I’m looking to get into the flight levels with plenty of remaining hp for more cross country performance.
IMO so many aspects of this installation are impressively well designed- especially the fuel system with its very efficient, low-amp-draw fuel pumps and header tanks. I’m intrigued by all such tanks that Viking has designed but I don’t recognize these. Were they sourced from somewhere else?
Is this a turbo normalizer? Meaning does the motor make 195hp without the turbo, and the turbo is just used to to augment for elevation as you get higher? Has anybody been interested in doing this motor in a sling TSI or HW?
Looks great. However the area behind the radiator seems a little small. Normally as the air expands though a radiator you need a bigger space after the radiator?
Great clean instruction. To recreate this what price would people be looking at? I cant wait to see its fuel burn on this aircraft and the controls when its complete. Great work!
@Viking Aircraft Engines. You never answered Tim Duncan’s questions. Please tell us about the turbo performance of the 195T at altitude. At what altitude will the horsepower start to drop off? Is it all boost for HP, is there excess boost to accommodate higher altitudes? How will this automotive turbo charger perform at altitudes it wasn’t designed for? Is there a concern about compressor stalls?
We have done our 130 and 150 engine in the Kitfox, but aren't they putting a continental large motor in the Kitfox 7 too? If so, this comes in slightly under that weight installed. Ideally though the 130/150 is best suited with a variable pitch propeller.
@@eggenfellner Do you have a constant speed prop option? What altitude does the 195hp start to drop off? I am very interested in BD-4C for cross country work.
Watch some of our Viking Talks videos, they are explained in them. The gist of it is, we don't run the blowby back into the engine as required by the EPA in cars, it runs overboard and we also don't do low RPMS - we are able to get all the benefits our of the engines, without the cons (we currently have about 1000 hours on our personally owned setp)
Us, neither - we stick to standard Ipads and keep it simple, the BD4 is a faster plane though we would recommend more than that, a lot of our customers are happy with either option.
We only have two proven propellers that work well with our 195T because of the HP, the DUC in both variable pitch and ground adjustable and the LUGA 3 Blade. The DUC is a bit more $, but gets better cruise speeds and is smoother. The LUGA offers more thrust, good for STOL. The DUC on here is a variable pitch, which is the only brand we offer in conjunction with our variable pitch setup, and it is pretty amazing, will be perfect!
@@eggenfellner thank you that's some great information. I've been trying to get more information on the DUC variable pitch propeller controller. It would be great if Viking would create a video describing the operation of the DUC controller. Your videos are outstanding so I believe you would make a great video.
We have everything on the Variable pitch a bit more in-depth on our website under "performance" that being said we use either a switch or a new controller we are testing. The controller isn't a DUC product.
@@eggenfellner it’s actually a legal requirement in most countries. Also icing and or blockage can occur at any time of year anywhere. It’s dependant on altitude and other atmospheric conditions. It is very irresponsible to not include it and opens you to liability.
Maybe in certified world, I can't think of a single experimental engine/aircraft that has it out of the 1000 we have out or any others. It is their aircraft and their choice. In no way shape or form is it irresponsible nor is liability a factor.
People get busy and life. He has it back in California, BD4 company had to do some rework on the plane, then shut down operation in FL if I recall…it’s come a lot farther than this video, but not airworthy yet.
Daniel B you are very wrong, the BD4 has won more efficiency races than any other plane in the world! It will fly faster, caring more weight, burning less fuel than anything out there. Look up cafe 400 for the formula.
@@waynetokarz174 that’s actually very interesting as I agree with the first comment that it’s ugly. But I’ll look into those performance numbers, ready to be surprised/impressed.
That lip hanging out the bottom of the firewall look very “un-aerodynamic “ as the owner of a -4 I would be concerned of this speed brake like protrusion.
