Default this might sound crazy but...

has anyone tried using a miniature jet engine from an r/c plane to keep the turbo constantly spooled? i'm thinking that it can be placed so that its exhaust gas can be fed through the uppipe into the turbo. i checked the egt of the small jet engines and they are in line with the egt experienced in a stock wrx.

in a way, it's like supercharging your car without drawing power from your engine and without needing to drop the clutch from a high rev.

these engines run on kerosene, so a seperate fuel system would be needed.

just an idea. let me know what you think.

i dont think that little thing is gonna overcome pushing all that air and keeping the bov open because to constantly having it spool ud have to be venting a lot of air

A supercharger would be much easier. Instant boost, and no hassles of having to mess with the jet engine that just keeps the turbo spooled. It'd also be annoying as hell listening to that BOV recirculating constantly.

Sure, but you need to have the volume, as well.

if it's producing that much thrust, shouldn't there be plenty of volume flowing?

gas consumption is pretty high at WOT. i wonder what it would be at 3/4 throttle or so. one gallon of kerosene would operate it at WOT for more than 5 minutes.

i don't think it would be practical for constant use, but in certain applications, i bet it would work. something you can switch on and off and adjust the power. maintanance wouldn't be that bad then.

Sure, but that is with a full open outlet. I doubt there are numbers out for that thruster that measure how much volume it outputs when you restrict the outlet, and at what pressures it can output those volumes.

It's 5.12" in diameter at the full body area, not at the outlet.

It's also producint 45lbs. of thrust, not 45PSI. That means that it would push against something at 45 lbs. of force.

ahha, man, some people think of the stupidest things. This has to be one of the top 10 that I have seen.

I thought with those you had to use a nitro blend? my r/c plane runs off a nitro blend, but its not a mini jet.
