Thrusters engineering question

[H34VY_R41N]

Hello, commanders!
Every thrusters' engineering decreases Optimal Mass parameter and increases Optimal Multiplier. Do I understand right, that it decreases overall thrusters' performance and increases boost?

[misc65]

Clean drives generate more heat over stock because of the increased power draw. It probably should have that removed so there is a reason to use them at all.

Yeah clean drives run cooler than dirty drives, but if you want to be cold you're better off not engineering your thrusters at all, clean clean drives are hotter than no engineering.

Clean grade 1: 20% thermal load REDUCTION from standard.
Clean grade 2: 30% REDUCTION.
Clean grade 3: 40% REDUCTION.
Clean grade 4: 50% REDUCTION.
Clean grade 5: 60% REDUCTION.

If your ship was was running hotter with clean drives, you must have changed something else as well.

With the thermal spread special effect it's a 64% reduction in thermal load. That's LESS heat from the drives, not more.

Escrito originalmente por EDWiki:

Clean Thrusters is an engineer modification that can be applied to thrusters. It reduces thermal load and increases speed, at the cost of increased power draw, and reduced integrity.

Let me further emphasise that point for you:

It REDUCES thermal load

Post your build because even though it says it reduces thermal load from the stats, the actual effect in game does not. I'm curious to see what your build is.

I just double checked on the dbx, with the coldest build you could possibly get, and I'm still right that clean drives are hotter than no engineering. Still curious what your build is though.

This should be pretty close: https://s.orbis.zone/ekpr

And like I said in a previous post (might have been in an edit so you may have missed it): With regular 4A drives, I'm idling at about 23%. With clean drives, I'm idling at 19%. I'm not maxing out my power plant though... I'm almost willing to bet you are.

Build them both out and look at your actual heat loads in game. Clean Drives run 1-2% hotter than no engineering at all.

I just did. 4D G5 Clean/drag thrusters on my exploration Orca give me 18% heat in supercruise:

Replacing it with the same unengineered 4D thrusters gave me 22%:

Dirty drives are the only effect ever worth considering anyway.

Not true.

Clean drives are a good choice for exploration builds.

Nuh-uh, reinforced with distributors so you can cram size 4s into an anaconda

Always go DD with Drag Drives for maximum speed. Unless you're using enhanced performance thrusters in combat ships. Then sometimes it's better to go with normal thrusters or drive distributors.

Speed is pretty much useless for exploration builds. Temperature is much more important there, because you will be fuel scooping, sandwiching between stars, visiting hot places like Black holes much more often than you will be racing. That's why using Clean is more beneficial than using Dirty on those builds.

Oop, I was looking at the dbx, not dbs. Interesting. Turns out I was also looking at idle heat and not the thrust heat. Idle heat goes up for every ship, but thruster heat goes down for the dbx / dbx, which it does *not* do for some others.

I also have not looked at the Orca so I suppose clean drives are cooler on it too, interesting.

Clean drives *do* run hotter on the Anaconda and Krait Phantom even with thermal spread though, which is why I stopped using them.

[JL::Jose-Juan Kenobi]

Clean drives run cooler, I have seen this in my mining Python, and my exploration AspX, DBX and Krait Phantom.
I rarely do G5 on clean drives though, usually G3 and then stripped down.

It says right there in the "box" of clean drives, thermal load -60% at G5

Thanks to everyone for your input.
Special thanks to Lightning and Planetwalker.

Bigger ships have more heat capacity. Use an anaconda and it will never ever overheat in a lightweight explorer role.

Just so that I have to use Dirty instead of Clean? No, thanks. It turns worse than a Beluga does. I would rather use something that is more pleasant to steer, as I am going to do it a lot while exploring. And I will use Clean to get the effect that I actually need in my situation, too.

Maybe I'll try the newfangled 5A double engineered FSD some day since it doesn't come in anaconda size and that would almost be decent jump range on a krait

The double engineered 5A FSD is brilliant I hit the grind to get two one for my asp and one for my krait phantom
