Turbocharging a Nitro 4 Stroke engine?
Hey guys! I've been out of the hobby for a few years and recently picked up a nitro RC. This got me thinking...
What are your thoughts on turbocharging a Saito FA-40a 4 stroke glow engine? Is it possible? I've been researching turbocharging on fullscale vehicles and theoretically it should transfer to smaller nitro engines. As long as you hooked up a servo to the HSP to richen the mixture as boost increases, everything should run properly. Currently looking into designs and who to request a miniature machined turbo from.
Also, I realize the FA-40a is an airplane engine so cooling could cause an issue on a car, but I've seen a few threads and videos where people adapt these engines to work in land vehicles.
Do you guys have any input?

My Feedback: (2)
There was some guy on this site, https://www.rctech.net who modified an OS26 4cyle engine and was running it in some off road car.just do a search there . A few years back OS Max had a 1.20 supercharged four cycle engine but its been discontinued. I really don't think you will see much of a gain trying to do this as these engines put out about half the Hp of the same size in a 2 cycle glow engine. If you have an RC car that takes a .21 engine upgrade to a 28 or 32 but be sure your drive train can handle the power plus you might have trouble getting it to fit!
good luck

Hard to imagine a turbo scaling down enough to work with a glow engine. And I doubt you'd get to hear the sweet whistle even if it would occur.
Now a mini nitrous bottle for that unlimited climb, possibly feasible!

May get a .40 or .62 for my plane, you're giving me ideas

I have spent a long time working with a 250cc motorcycle engine . I use it for landspeed racing with nitrous. I have turbocharged them using the smallest turbo available and was not thrilled with the results. Valve springs are one problem I ran into after over coming a number of others.
My first thought is lubrication of the turbo. Simple pump, tank and lines. But that will be needed. Next is making a turbo small enough to work and able to spin at the required rate to produce boost. This would be a big project. Totally possible but the weight and other factors make it questionable over bigger engine or more nitro.
