Starting a Vintage 1918 WWI Curtiss OX5 V8 Aircraft Engine at Sun N Fun 2021

1918 World War 1 Aircraft Engine made by Curriss. 500 cubic inch with hemispherical heads and a unique push pull camshaft!
Filmed with a Panasonic GH5 camera - amzn.to/3eN0Op2
500 cubic inches liquid cooled. Really cool engineering on the valvetrain mechanism.

Crazy how this is a 500 cubic inch hemispherical combustion chamber V8. When you compare it to modern top fuel engines that make 12,000hp with the same cubic inches you gotta admire how far engine technology has come in just 100 years

[@indopleaser]

so glad he explained the pushrod situation, exactly the video i was looking for. amazing engineering!

[@wildcat6669]

Cool that it's also a hemi

I found out that my great grandmother was a 2nd cousin to Glenn Curtiss. Whoooo hoooo!!hoodoo!!! 😁

[@saikhuahmad]

Beautiful engine

[@pimpompoom93726]

The OX5 did the job, but it was under-powered at 90 HP for the Curtiss Jenny (which had a lot of drag). OX6 was a little more powerful at 105 HP and had two magnetos for safety purposes, but the Jenny really needed 120 HP and that ended up being provided by the Hispano-Suiza V8 (built on license in America as the Wright-Hisso) which also had an enclosed valve train with direct lubrication. I wonder what Curtiss could have come up with if his team had proper funding in 1914 to develop a better training-aircraft powerplant? Curtiss was a very talented and creative aircraft and engine designer, probably the best American designer at that time.

It sounds awesome

[@MrJeep75]

Love it

[@InternalCombustion]

Thx!

[@adsyoffinch]

Thanks for the slo mo that really demonstrated the genius design! Were these engines also built under license by Renault in France?

[@fourfortyroadrunner6701]

It's a wonder that flying ever got off the ground, LOLOL

[@_levandre_]

Can I put it in my miata pretty please?

[@SUPRAMIKE18]

I'm still not quite understanding why the coolant from the top of the cylinder is piped down through the intake manifold. Was it for carburetor de icing? If so that's pretty clever for the time.

[@jimbos3421]

I question if the hose clamps on the prop boss are “aviation standard”?

[@spannaspinna]

Absolutely

[@martinweir283]

My evo motor...more are less..no liquid cooled

[@jdmslutsixtynine1399]

Gotta love American V8’s. 15L engine, 90hp lmao

[@Red-rl1xx]

The Liberty V12 engine produced 425 hp.

[@viperq]

That is a lot in 1918.

[@BikerJim74]

on par for 1918 you dumbass

[@jamesyoung9146]

To bad this a world War 1 engine and its only a 500. Which is equivalent to 8.1 not 15 litres.

[@jdmslutsixtynine1399]

@@jamesyoung9146 lmao, you say that like its an acceptable amount for 8 liters

[@dougshadrick9776]

That looks like a liberty engine actually
