Vector Thrusters vs Wire Thrusters

[Ergzay]

No matter what I do I can't seem to reconcile why the two give different thrusts. I have a wire thruster and a vector thruster using the same model (compass model as vector thruster cant use anything else) attached to the same prop (0.75x0.75x0.75 PHX block) both with the same multiplier (rather almost, the regular thruster is getting -1 while the vector thruster is getting -1 Z and 1 Mul which gives the same effect (world coords)) yet to make them move at the same speed I have to set the internal multiplier on the regular thruster to 250 and the vector thruster at 343. This makes no sense. Could a wiremod dev please answer this? I was digging through the lua source, but too many of the functions route to functions I can't find.
This line for example:
ThrusterWorldForce = ThrusterWorldForce * self.force * mul * 50
I need exacts for my contraption I'm making. I really want to find out the exact equations how the weight and thrust work for thrusters as it seems to differ for size of the model and for the weight of the model (more so for the size). And nothing seems to scale linearly and they all scale non-linearly at different rates depending on size weight and kind of thruster, really is a mess.

using the weight tool, make the thrusters weigh exactly the same, then tell us how it goes.

[Ergzay]

Did that. By having them use the same model they are already at the same weight (I checked when I did it). Thats what I meant by it doesn't make sense. They are even further different when using different models and the same weight.

[Pyro-Fire]

look at the code, maybe they are made different.

Any developers out there?

try taking the prop collision of of the regular thruster

It's off by default I think, and even if it isn't, I've always had them that way.
