The penny never dropped with me that 1900 and 2200 water-cooled flat four engines are available (in South Africa) under $1k on exchange. Much reading of...
I've noticed that the lightweight cylinders from Great Plains seem to have dissappeared from their site? Have they proved unreliable or are they just out of...
I was waiting to see how well they worked in real life. They have now been discontinued (or so I have heard) I think it was more of a failure in marketing...
These only made a cheap engine too pricey. Who wants to spend more on the cylinders than the rest of the engine? Not most builders. Hal ... From: J L To:...
There is a Russian redrive that uses planetary gears that seems to be very adapable. It is sold in North America by Airtrikes (in Canada). I think it costs...
The onlyproblem here would be what they done in the planetary drive for coupling to the engine. The VW engine has large impulses and can destroy most of the...

Hi Steve If the motor is installed properly I cannot see why the motor should not be able to develop enough grunt for the application. The biggest problem is...
Hi Gavin Maybe some of the lads misunderstood the original question. I am sure the Great Plains heads work. My curiosity is about the VW water cooled flat...
Steve The waterboxer looks like a Subaru EA81---integral waterjacket around the cylinders. It is not just the heads that are watercooled. I also believe that...
The Russian drive is called SPG-2 and is a spur-gear reduction, not a planetary. Erik. ... be very adapable. It is sold in North America by Airtrikes (in ...
The "Waterboxer" is not a particularly distinguished engine, and is far too heavy for it's horsepower to make it worth investing your time and money in. Very...
It seems that keeping the heads cooled during full power operation is the "achilles heel" of VW engine. Since full power is normally limited to a few minutes...
A great concept and worth working on, but I believe that when we establish the calorific requirements (BTU's?) for dealing with that level of heat, we will...
I think this is interesting however the quantity of water might be bothersome. I mean, considering a gallon with pump and small battery, you might get away...
The added weight of the tank and pump should be no more than five pounds. The plane already has a battery to power the pump. A gallon of water weighs eight...
My airplane has no electrical system so that's why I made that comment. I say hook it up and try it out. With a temperature gauge in the head area it should...
... The Type 4 engine was a brand-new construction, designed and built for this model. No part is interchangeable with the upright-fan Type 1 engine and trying...
there was a system for the land rover off road boys,in the 80s that sprayed a mist of water into the intake, just as you said cooler heads more hp, get it...
... all of these advantages come at a price: weight & costs... Whereas you might be able to configure a magnesium Type-1 to weigh in at some 165-175 pounds...
Hey Gang! This is just a reminder that the 5th annual Alternative Engine Round-up is just around the corner. Forums and presentations all day April 26, located...
Hello My first post on this site. I have a 1835 that I am trying to set the correct mixture (Main jet).It has been I think running to rich,exhaust are black...
... No, they have not disappeared, but something was changed. Last year they had Nikasil cylinders with 92 and 94mm bore. Nowadays, only 94mm bores are...
... Good. (The oxygen sensor would give anomalous results with leaded fuel.) Your gross symptoms indicate excessive fuel. This could mean inadequate AIR,...
Thank you very much for that well thought out reply,I appreciate it. Ive checked the needle and seat as well as I can and it seems to be doing its job.The...
Knowing the engine has operated properly in the past using the same carb & ignition system is of enormous value when debugging this sort of problem since it...
After trial and error + finding out that a o2 sensor has to be at 600C to work (I moved the sensor closer to the head)I have settled on a jet of 130 after...
