Hi guys
on the compressor a/r, can the housing be too small? I have a 3076 (5012) fitted with machined out std r33 housing .5 ish i pressume, and had a machined out .6 std exhaust housing, which i have since change to a avo .73, which did fix the compressor surge issue but hasn't given up much more top end.
Does feel like it has more torque, with 500 rpm more lag, have been told should see 270 rwkw but only gets 240 might get 250 with a push. Anyway the hot pipe gets bloody hot could this be related to big wheel little housing?
