I added a considerable amount of torque when I installed my billet intakes, but my engine is a 904 with ported/polished head and oversized valves, and my carbs are bored 3mm over stock size. So I can't really say if you will see the same jump in torque I did. Red line is 904 w/headwork, blue is with bored carbs, black is with billet intakes


Always remember to be yourself. Unless you suck. Then pretend to be someone else.
