Pratt & Whitney R4360 Full Start July 11, 2008

[MrHoldenta]

I wish I had known about the restoration of this fine engine. I was a mechanic on them for 31/2 years. USAF B36. I know them rather well having changed almost every component on them.

SMOKIN THUNDER sounds like 7 big block chevys

[antiussentiment]

what a beast. well done to you all.

much respect to people who preserve and restore mechanical/engineering history

[erad5]

damn, its awesome to hear this engine on the seafury dreadnaught, especially on takeoff!

[Bamchucknorris]

damn it was shooting fire at 1:16

[NcalBiker]

You mention that the engine was stored "in the can". Can you elaborate? Where was it found? How was it discovered? I have often wondered where people find these treasures, and have thought about the restoration and saving of these works of art over the years. A P&W radial is indeed a bit larger than a 5hp hit and miss, but it would sure be as much fun to fire up when finished. Great video. Thanks for sharing, it got me fired up as well...

[NastyNixels]

Thanks NcalBiker. We received this engine from a museum down south that was deaccessioning it from their collection. It was part of the H.Hughes Spruce Goose cache of material that was given away when Summa Corp. was going to cut up the Spruce Goose. Our museum purchased it and then the "restoration" began. Take a look at our other videos - on my name as well as the PenngrovePower name on YouTube. You can go to our website as well and see some images of the machine being refurbished.

[NcalBiker]

CUT IT UP??? Where's my gun. Glad it went to Oregon where it will be safe! I hadn't heard that. Until now, I wasn't aware of where you were. I get down to that area on the occasion. Looking forward to getting all fired up at one of your fire ups. Again, great video coverage. Hello from Eureka.

[Velktron]

What a monster engine!

R-4360 is a type designation for the engine: R for Radial arrangement of pistons, 4360 for the displacement in cubic inches. 4 rows of 7 cylinders each=28 big, air-cooled cylinders. These engines, although bigger and more powerful than the R-3350, had better cooling due to the fact that each row had only 7 cylinders, instead of 9, and sheet metal ducting guided cooling air where it was needed most.

[scruttart]

Great clip,love the way you can see every explosion,without a prop acting as a giant cooling fan how long can you "safely" run this big beauty?

[thuglifestyles]

What is 4360? It's power in hp or type?

[curdle1]

its cubic inch displacement of all the cylinders

[thuglifestyles]

ok! How many bhp in this engine?

[Anobehell]

3,500 to 4,000 Bhp

[emtee22]

The old timer with the hat on is probably so well versed in this engine he could build it with a pair of plyers and a set of screw drivers.

[NastyNixels]

Steve Phillips is the engineer that restored the R4360. He did so with very little documentation and no help from anyone that was an R4360 engineer. These engines are complicated and the vets from WWII don't remember much from 60 years ago. In addition, no one was charged with knowing how to address all aspects of the machine. Steve's ability to do mechanical archeology is impressive.

Thanks for viewing.

[emtee22]

its pretty cool watching the old PW's and Merlins and the such starting up. You had to have 3 arms. Prime, choke, start, throttle, unchoke, cut throttle.. Then it runs. Everyone always says, "why didnt the pilots that were stations at Pearl Harbor just jump into one of the planes and fight. " Starting one of these engines was a proccess.

[FiveCentsPlease]

Little documentation? I have a copy of an R-4360 overhaul manual that is a reprint. A good number overhaul manuals can be found in reprint for a reasonable price.

[wofobo]

"c'mon baby, c'mon for papa"

[wilsonces]

Wow. just love the old stuff. That era was so elegant. But please, use a club prop.

[HTM1982]

How many MPG ?? ... =P

[ilikepie3752]

-50 mpg jk

[NastyNixels]

At 28 cylinders, this is the largest production reciprocating engine to be made. Four rows of seven cylinders, the 4360cu/in. engine produced 3000hp in this earlier version with 7 high-tension mags. Later engines produced 4300hp using low-tension magnetos. There is quite a bit of information about these engines both online and in print. Thanks for viewing

[jazilasta]

No, the diesel engines they build for large ships are much, much bigger. More than 100,000cu/in. producing more than 100,000 hp. :-)

[zerstoren46]

Great job Guys thanks for sharing your project with us!

[fighter0w1]

Just two words for you, TRUE POWER!!

[Shalinar45]

What a tempermental BEAST! Thats my favorite round-engine, right up there with the R-2800-62!

The Corncob is very good at giving you the finger and not starting if you don't finesse it just right.

[PenngrovePower]

We now have a YouTube account - PenngrovePower. Check out the run we did on our new trailer. The restoration is complete.

We also have some other videos of the 4360 running that I've hosted.

Note the test club and the short pipes.

[grogadile225]

You chaps are sensational. :-)

[anickode]

Nothing on this planet sounds as good as a Wasp Major coming to life.

[NastyNixels]

We ran out of time to modify our prop to a test club. That'll happen in the coming weeks.

Thanks for your interest.

[Mercrewser]

Great video, I've been waiting to see it run. Any plans to install a clipped propeller? Hope to see it running up at speed soon!
