Me too Illwood, I went from an SN95 FMS 65mm to the Fox BBK 70mm and noticed no ill effects. Any power increase I think came from going from the GT to the cobra intake.illwood said:I run a 70mm TB after my fox swap. I haven't noticed any problems (check my sig for minimal mods).
I know my intake and TB is too big to be helping much, but I just finished the swap and haven't made it to the track to test it yet. I'm planning on having the motor grow into that setup (come heads, cam. . .)
