hey fella's, got a question. I want to know what the biggest engine's you have heard of are. If you can, give the sizes to me in liters and cubic inches. I have a friend who has trouble visualizing cubic inches. He grew up in Asia, what can I say. Try to keep it limited to just automotive engines if possible. If you want to throw in the hp and trq outputs as well don't let me stop you That is what it is all about anyway

 

in a tank with a 1000c.i. and i think 17.0 liters (diesel) and a 632c.i. gas engine 8.0 liters

 

Rolls Royce used to have a 9 liter engine..

 

this is the biggest I have ever seen

hey I got one, its not an automtive engine but it's big.
9,655 hp
20,286 cu. in.
11'' bore
333 L
V18

 

The biggest engine I have seen personally was a V16 diesel in a railroad locomotive. There was a link here some time ago about a custom built diesel for a huge container ship, the engine was several stories high.

 

Here it is:

Was in the Peerless 6-60.
824Cu in!!!!

 

I think we're looking for different answers. I believe 77fordguy has it for biggest piston engine (OK, it's diesel, not gasoline).

And I'll not argue with Guiness on that 824 cube car engine.

I've driven old Kenworths with Hall-Scott inline six gasoline engines around 1,100 cubic inches. They used to be very common.

So are we looking for biggest engine, or biggest car engine, or biggest over-the-road truck engine, or biggest land vehicle engine? Or what?

Of course, all of these answers are interesting.

How about 1,566,002 cubic inches, 108,920 HP, 5,608,312 ft-lb torque!!!

Read all about it here: http://www.bath.ac.uk/~ccsshb/12cyl/

Sorry boys and girls, I'm afraid it won't fit in your Superduty!

 

Lets try to limit to engines that will fit personal vehicles, whether it be car or pick up. Answers have been quite interesting though

 

The Tucker Torpedo in the 1940's hand a 500 something cubic inch air cooled STRAIGHT SIX!!!! The car, and the engine only lasted a couple of years. Go figure.

jay lenos' car has a 1000c.i engine in it and its street llegal
The M47 is a 12 cylinder, air-cooled 1,800 cubic inch motor makes 990 horsepower and delivers a wrenching 1,600 ft/lbs of torque.

 

Actually the Tucker was an opposed six based on an aircraft engine, 355 inches, 166 hp. 51 were built, 47 exist today.
The Bugatti Royale had a 12,763cc engine (300 hp at 1700 rpm) and 36" wheels with an outside diameter of 40". After the Royale was discontinued (6 exist today), the same engines were used in railroad switch engines. This was one BIG car.
