as the title say s really my mate wants to fit nos but has direct to head tb from how how can it be done
an idea would be to mount some foggers and extra fuel injectors pointing into the mouth of the trumpets, then youd proly get gains even when he's run out of nos by setting the 2nd set of injectors to come on and take over from the other set at high revs, also with nos it would have a chance to vaporize properly and cool the charge, which is always nice
