Honda 1.8L running on test stand video
For those of you who enjoy the building part of this hobby, especially the engine side of things, I thought I would post a link to a short video I made of my "alternative" engine set up.

It is Honda R18 Civic engine. 1.8L. This engine is extremely common. It is in current production and has been around for 10 years in various Honda cars. It is a standard port fuel injection and COP Coil on Plug ignition. It has many advanced features like individual oil injected pistons and many other features.

I am also using the Viking Aircraft Engine PSRU (gearbox) and a 68" tapered Warp drive prop. I am very impressed with the Viking gearbox.

One of the features of this set up that I really like is the SDS EFI system. This is a fantastic engine controller. There are over 1500 planes flying with the SDS EFI system. It is a very complete, and flexible, and easy system to install. It manages your fuel injection as well as your ignition system - all easily user programmable.

I am not flying with this yet. I have an RV6a airframe done. I will need to build the engine mount and then work on the panel, and other finish work. I have a full time job so who knows when Ill be flying.

Feel free to ask questions.

Honda engine
looks like a very interesting project. What sort of horse power do you expect out of it? The SDS system looks very nice.

Very interesting indeed. Brings back memories of the CAM100 engine.

Will be even more interesting to see how the Viking gearbox holds up. I hate to say it but I think Jan is still having his customers do his development testing for him. I really hope this isn't the case here.

Don't ya just love how the engine starts and runs so smoothly?

Great job Charlie. Very cool project. Make sure you give us more updates as your testing continues.

Seeing that R18 engine brought back many good memories of tinkering around with the B-series engines of the 90's and 2000's

I still have an old Acura Integra as my beater car, that has a B18A engine in it...with over 357k miles on it.

For those of use who are unfamiliar... what's the flight-ready weight and HP of that setup?

Does it cruise up on the beefy side of the cam with VTEC fully shifted or are you on the economy side and cruising evonomically? Will you be dependant on a single or dual oxygen sensors? If yes, will you avoid 100LL so your oxygen sensors are not fouled?

I had a tapered, 3 blade Warp Drive ground adjustable on a 125 hp O-290D on a clipped wing Wag Aero Cuby. I was asked to not idle it below 700 rpm as the direct drive impulses were a bit rough on the light prop. It was fine in the 40-130 mph range on that draggy profile. If I needed lower idle I was to go to the four blade, FWIW.

Notes below video, on youtube, say 130hp and 300# weight, all up.

I wonder what engine/prop RPMs are at 100%, what they will be at 75% cruise.

VNT & Vtec Controller
A set of cams, VNT turbo and a Vtec Controller would be a match made in heaven.

Turbo for this engine
A company called Turbo Specialties makes a bolt on Turbo for the Honda r18 engine.

Model: Engine R18 W/T25 Turbo
Part# HC2504E

I wanted to try it on my 2010 Civic EX, but haven't yet pulled the trigger yet. Can increase HP significantly.
