What is the Largest Rocket Engine for KSP 1.1.3?

[Turk_WLF]

I’m just wondering if anyone knows what is the Largest Liquid Fueled Rocket Engine as far as the terms of Thrust &/or TWR out there for KSP 1.1.3, outside of the default Engines (Mammoth, Rhino, & Mainsail)?

There are too many mods out there to list them all.

Probably NecroBones' Sea Dragon first stage engine from his Real Scale Sea Dragon mod:

Though a 360MN engine might be overkill (that is 10 times the thrust of a Saturn V).

Edit: if anyone has a mod that beats that, I'd be more than curious to see it

 

If you want to stay reasonable, I think you could get a F-1 engine from one of the many mods that include them. If full scale, you'll get 7.5MN of thrust.

@Tex_NL No need to list them all, you'd be hard pressed to find a bigger one than this.

Are we counting or not counting the Orion drive?

@Gaarst @Alshain
Those are insane. They are big but also pretty unusable. Unless of course you want to launch an asteroid back into space.

Personally I've always preferred the engines from KW Rocketry. Not nearly as big or powerful as those you linked but a lot more realistic.

Well the OP didn't say anything about being usable

I can't tell you which mod holds the record now, but back in 0.13 there was a mod called "Uber Hyper Giant Engine" or something like that. The bell of the engine stretched over the whole launchpad and its thrust was astronomic.

However, I think that the 7.5 engines from Space-Y Heavy Lifters Extension would be comparable to any "Uber Engines" lying around here, especially if clustered somehow. They are very efficient and provide a high TWR if used properly.

A plus would be that rockets made with 7.5 parts tend not to wobble because the tanks are naturally fatter and shorter yet hold enough fuel to power beasts such as the Omega-Ratite.
