If it is now acceptable to put an LS1 in a P51 replica and put your life on the line in doing so!

The build reminds me of the many teener projects I've heard about...20-years and 5000 hours. (IMG:style_emoticons/default/rolleyes.gif)

60+ years after my cousin Billy (Tiger) flew his P51 in Germany, he went up for a ride.
He said his plane had 2000+ HP.
After the war, he graduated from MIT and at 93, he's sharper than I'll ever be.

We saw Billy over Thanksgiving. He's a great guy. Lots of great stories if you ask but like most vets, came home from the war and never talked about it. He started an advertising and marketing firm after college. It wasn't until 60 minutes did a special on him about 10 years ago that he even mentioned flying. He was the first pilot to attack and damage a German jet in a prop plane. He lamented that even though he had a modded turbo and pushed the engine past redline, he couldn't make up ground on the jet.

Her's a funny (true) story that he likes to tell.

Wow - punching holes in an ME-262 from a P-51 has gotta be one helluva ride and a rush! Congrats to him for having bowling balls of steel! (IMG:style_emoticons/default/smilie_pokal.gif)

Video description says it is an LS-1 from a Corvette, 16 years and 5000 hours to build.

All very interesting; but not 914 or even Porsche. GM engine conversion of a fighter plane should probably have an OT designation.

And we have threads about people being concerned with driving over a 3000' pass! LOL!

What kind of extra engine management / fuel control goes into something like this?

Engine management and fuel control would be about as simple as you can possibly get, and very mechanical. It may have centrifugal advance for the ignition, but it might be wholly or completely manual! Fuel will generally be delivered by a carburetor, with a manual mixture control.

The emphasis is on simple and reliable, and secondly on giving the pilot control.

Remember that aircraft engines run in pretty narrow RPM ranges, and quick transient response is not required. It is generally fine if it takes 10 or 15 seconds to get to full power.

Supercharger boost would be the primary power control. They ran up to something like 30 PSI of boost at maximum. The Merlins had large two-stage superchargers on the aft end of the engine.

The Allisons were built for turbocharging, and not that much work was done on mechanical supercharging. The turbo systems would up being problematical to fit in a single-engine fighter aircraft, which kind of neutered the setup in the P-39, P-40, and early Mustang. It worked pretty well in the P-38 Lightning, at least in the Pacific where it didn't really see cold weather.

Don't know what kind of setup the replica has on it, but it wouldn't surprise me if it's just a single carb and mechanical-only distributor.

EDIT: Just looked at the "exhaust" video. It shows stock-type coil-on-plug ignition and a fuel-injection manifold. So it looks like standard street-car type stuff.

Interesting. It also appears to be running with a stock ECU. There is a reason this would be classified under "Experimental Aircraft"...not for me.

BTW: This is OT... (IMG:style_emoticons/default/slap.gif)

Then title it that way. Is that so hard? (IMG:style_emoticons/default/slap.gif)
