Re: Decided to buy a new engine for the Z
LOL!
Gas mileage prolly ... not as good as your LT5. But! You'll be the only one on the block that has one like it! I doubt Pete or Marc will have the quals to work on it....Bob Gillig...maybe! LOL! |
Re: Decided to buy a new engine for the Z
Might have to modify the front crossmember
to get it to fit? Hope your local gas station carries 115/145 octane av-gas... |
Re: Decided to buy a new engine for the Z
Lol... I was at the Reno Air Races today, saw this and thought of you guys! I have no idea who made it or how many cylinders it has. Must have been a nightmare to work on and keep running.

Re: Decided to buy a new engine for the Z
From what I have been to google it's a Pratt & Whitney 5600XBSAP that puts out 7000 hp!
"A fun display for the fans was an engine shown behind the Grandstands: the Pratt & Whitney 5600 XBSAP! A fifty-six cylinder radial with eight rows of seven cylinders and displacing 8,720 cubic inches! A massive R-8720 power plant. A lot of people stood around scratching their heads over this one: that is, until they realized it was two R-4360 power sections bolted together! A lot of “experts” and “aviation buffs” were heard to make some interesting rationalizations and statements of “fact” about its history!" http://a63.tinypic.com/2crpph1.jpg |

The B29 was powered by the Wright R3350
The further developed Boeing B50 had the Pratt & Whitney R-4360 Wasp Major |
Re: Decided to buy a new engine for the Z
After further googling the concensus appears to be that it's a mock up. Probably never ran. The biggest and last production radial engines P&W ever produced were the "corncob" 28 cylinder R-4360's. Cooling, fuel economy and the development of the jet engine killed it.

Approximately 18,700 PW R-4360 engines were built. According to Wikipedia these are the planes it powered:
Aero Spacelines Mini Guppy Aero Spacelines Pregnant Guppy Boeing 377 Stratocruiser Boeing B-50 Superfortress Boeing C-97 Stratofreighter Boeing KC-97 Stratofreighter Boeing XF8B Boeing XB-44 Superfortress Convair B-36 Convair XC-99 Curtiss XBTC Douglas C-74 Globemaster Douglas C-124 Globemaster II Douglas TB2D Skypirate Fairchild C-119 Flying Boxcar Fairchild XC-120 Packplane Goodyear F2G Corsair Hughes H-4 Hercules ("Spruce Goose") Hughes XF-11 Lockheed R6V Constitution Martin AM Mauler Martin JRM Mars Martin P4M Mercator Northrop YB-35 Republic XP-72 Republic XF-12 Rainbow SNCASE SE-2010 Armagnac Vultee XA-41 |

My son in law says Pratt no longer supports this engine.

Re: Decided to buy a new engine for the Z
To me the amazing part is that this is 1940's technology! At the same display they had a cutaway of a basic P&W radial engine. The supercharger was actually integral with the block (if you can call it that) with variable boost controlled via its own gear set. In other words the supercharger speed could be shifted like a manual transmission. Cool stuff...

Re: Decided to buy a new engine for the Z
Turbocharged AND supercharged!
Not to mention thrust from the exhaust! 😋 |
Re: Decided to buy a new engine for the Z
Compound turbocharger mechanicaly connected to the crankshaft output.

The piston engine is acting as a gas generator to run the turbo which helps power the engine's output shaft (not to mention the thrust factor, wonder how much that added?) Not a turbocharger in the way many think of it... |
Re: Decided to buy a new engine for the Z
Like invisioned for the P&W R-4360 51VDT prototype which attempted the concept of using the piston engine as a gas generator in conjunction with a combination turbocharging/thrust producing gas turbine

Re: Decided to buy a new engine for the Z
Hey if you can get one into a VW, we can get a bigger one into a ZR-1!
