Title: 2.5" pipe work vs turbo Compressor outlet
Post by: rio_gti on 12 July 2012, 23:34

Was wondering why if the outlet on the turbo is about 1.5" why is 2.5" necessary? And the charge pipe is about 2" so do I need a bigger one or leave this as is??

Just havin a midnight thought that's all  :wink:

K03s 2" is fine but if your going bigger K04 or big turbo then the turbo can pressure a larger volume of air that needs to be forced through so 2.5" is what you want.
