MAF to big?

[94_5.0]

would a 80mm MAF be too big for my engine set up with 30# injectors and a 70mm T/B? Or would a 75 or 76 MM MAF be better suited for my set up?

I will be adding a single turbo (66MM) my engine later on, so I am trying to plan a little bit a head.

Hell I am running a 87MM on my car now. My car is N/A no power adder.

There is no such thing as too big when it comes to MAFs. As long as it has the right calibration.

How about one that is too small. I know I do not want to go smaller than the T/B but is there a rule-of-thumb when sizing the two (i.e., 5mm larger than the T/B)?

From what I have heard, If the throttle body is 75mm or above you have to port match the intake.

ok wait is this a blow through MAF or a draw Through? Draw through the bigger the better blow though you want to keep it at 75mm with a no bigger then 70mm TB with a 66mm compresor wheel....you can go bigger but the intake pipe coming of the turbo to the intake is likely only to be 2.5in some are as small as 2in....this is to keep Volcity up.
