Had one of these monsters in an unlimited hydroplane I had a chance to drive a few years ago. The didn't use any type of water pump for cooling, so I had to keep the speed up to a min. of 95 MPH just to "ram" enough water through the engine to keep it cool, never pushed the old boat much past 135 mph, yet in her day she was a 195+ race boat. Unreal power and sound !!!!
The pitch changes , the prop isn't flexing.Thanks to all who looked at our video.Will be posting more in the coming months.This engine is currently in THE GUNFIGHTER owned by the CAF.
Sometimes I just can't believe how uneducated people are. Do you all really think the prop is flexing? When was the last time you saw a prop A/C running at full speed with its prop flexing at that speed?
if you cant be bothered to help improve peoples knowledge, say nothing. no one has seena prop at full RPM. the only reason you can see it here is the stobing effect of the camera's CCD as it images the scene dozens of times a second (you get the same effect when shoting mag wheels on a car) . Nothing to do with pitch changes on the blades, the relatively low RPM range the engine covered would not have been noticable via camera.
A beautiful vid os a beautiful engine, cheers for sharing :D
The prop isn't flexing. Amateur video cameras run a high shutter speed and the weird strobe effect is seen in the camera, not in reality. At most a prop might flex a fraction of an inch at the tip.
man the sound at 3:30 sent a shiver down my spine.

you would think the power of the engine would pull the truck brakes or no brakes

I got the chance to visit Central Cylinder just recently when we dropped off some Merlin heads for a Mustang project.
I saw this truck parked there inside the shop and wondered what it might look like with an engine mounted and running. Now I know! Great stuff!

I´m impressed to hear the stall on prop by working engine opposite.

So cool how the camera captured the high speed of the prop like that.

time to use a different prop I think, that's an awful lot of flex

See... what you ought to do is install a pusher prop on that thing and teach them tailgaters a lesson they'll not soon forget!
I'd imagine you'd cross the country in three hours wit that setup, too!
Kidding! Sweet-sounding Merlin. If I'd taken my eyes off the screen, I'd swear it was a P-51!

Wow. Nice to watch pitch and load changes. Great test rig. Ever consider releasing the brakes? How many gallons did you run thru on this test...15?
