Inlet manifold NICS system

olympus · Feb 14, 2018

Hi all Sorry I was taking the micky.... I was of course refereing to YICS
Has anyone tried altering the diameter of the bleed holes in the inlet manifold cross over stubs.... and has this had any affect on mid range torque or was it to a detrement??

I used a large [3/8th inch] crossover with a needle valve to adjust it. It will make differences in the fuel curve between idle and 1/2 throttle or so.
No change in the torque though if the fuel mixture is correct.
