Been thinking (smoke is rising)

[Dream to fly]

I have been looking over my plane and all the comments on the ROP/LOP and without a monitor I am guessing what is really going on.  I fully understand that BUT what if I build a poor mans turbo and can collectively pull forced air off the prop and funnel it into the cowl scoop.  Would it not "charge" the intake a little giving me more MP.

Not enough to matter....

The nitrous it is

2 extra molecules of oxygen has to be better

Pretty sure that was used in WWII.  and pretty sure in my mind that M20 F is just a P51 in disguise.

That is so cool!!!  Its too bad my wallet can't keep up with my ideas. I am so tempted to go really big.

Ok so where is that button that sheds the Mooney disguise and I  have the mustang?????

Not sure about Nitrous but Water Injection was used for added power

[Yetti]

A Proper driven supercharger could be fun... Just a little bit longer belt.

If that's really to scale it means a P-51 has no hope of fitting in my hangar.   Bummer.   :'(

Still thinking a ram air that functions or an electric turbocharger

So are  you say'n  since Mooney is in Texas and I am told that everything is bigger in Texas. would that mean that someone  from Texas  needs to put a Rolls Royce Merlin in a Mooney?

[carusoam]

Joe,

Aren't you describing the air intake on some Mooneys...  the system that bypasses the filter and gives an improvement to MP?

Modern intakes did away with this charade...

Go modern...

Mooney was working with RR to put a turbine up front... 2008.

Water injection didn't give more power.  It gave internal cooling similar to extreme ROP... which allowed gigantic superchargers to stuff gobs of air into the engine.

If you think rust is a problem with cams now, water injection is going to be expensive.

Use caution stuffing more air into any engine.  You have a good chance of sending broken fan parts into the engines intake.

You are probably better off with a big button mounted on the instrument panel marked War Power...  

Best regards,

Buy a plane that has what you want. If you dramatically exceed atmospheric pressure by somehow ducting ram pressure you will most likely catch on fire. The vent hole on the side of the injector nozzle that is designed to atomized fuel at idle by bleeding in atmospheric pressure and also reduces vacuum creates due to the close throttle plate, is going to spew fuel out of it at wide open throttle and you will catch the whole damn thing on fire. By a turbo plane.

STC it and make a small fortune. It'll take a large fortune to get the STC approved.

Cessna did this on I believe some of the bigger Twins. The air intake is on the right side of the engines on the leading edge of the wing to take the downward swing of the prop, mid-span blade length from the cowling. I think someone told me it gained like 1" MP?

It was a thought.    Wasn't trying to reinvent the wheel just make it better.

Rocket Engineering did exactly what you're describing to the Missile conversion

[KSMooniac]

Lopresti did it on a Piper upgrade long ago, and even got a special prop made with tabs on the inboard trailing edges that lined up with the ram air intake. IIRC the prop was even indexed so that the tabs passed the intake at an advantageous time to give an extra charge of air during the intake cycle.

You already have a head wind of 150K or so....the extra wind(pressure) from the inside of the prop I would think is marginal, I would be curious if they bother to measure it? They might have relocated the intake on the Missile to top of the engine to prevent icing.

What is that little hole doing?

@M20FanJesse, are you paying attention? I may have to get one of these myself . . . . .

I was just about to post a shout out to Jesse but you beat me to it.
