I just eliminated the heater passage on my cylinder head breather tube (see picture link).

Do you think I will have any improvement with this?
Because normally the hot coolant (coming from the engine block) goes through there in order to heat the vapours coming from the head.
I believe this is mainly for low emissions, but it must heat the intake air and detiorate performance.

 

Nobody?

 

so you looped around the TB? as far as your picture it looks like you did it wrong; you should not mess with the tube that goes from your valve cover to the intake.
you could put a filter on the valve cover, but it wont scavenge crankcase pressure efficiently.
you can loop the lines around the tb though.
Im not sire what you mean about ''heating up the vapors from the head'', that's not the case... coolant goes to the tb in order for it not to freeze in cold weather..

 

No - coolant is not routed through that tube so as to heat the vapours coming from the head. It just so happens that Honda designed that tube that way - its just coincidence that coolant runs through one tube and vapours run through the other.

I would just put thing back to stock.

 

Did you see my answer on that other BB?

The main flow direction of the air is FROM the intake TO the valve cover.

The heating is to prevent oily air from condensing out into liquid during brief periods of reverse flow at WOT.
