I’m not sure either 
This aftermarket brand does a lot of stuff with engine modifications.
I’ve seen it before; I just cannot think of the name. It is not TOO obscure, I know that.
Maybe try cropping it differently? Or would that give it away?
I’ll try with this different crop. Consider this to be a second hint of a sort.
Well, I give up. I have no idea at all as to what this could be 
.
Me neither. Stopped looking at it since I have no clue at all (until the point where you know the answer, and you are going to be like. Ah hell no.)
Can we have a hint?
