Hey all,
I'm coming to you all since yall have much more experience in this department than the b6/b7 crowd lol.
I have a B7 S4-T i'm hitting the max on my MAF at 502.7g/s (only 11psi :( ). I'm pretty sure my factory Bosch MAF housing is 83mm ID. Is that correct?
I've found various aluminum/billet/shiny pieces of the 85 and 90mm variety. How much more room will that allow for? I only wish to do this once.
