MAF and/or Throttle Body size / sizing chart ?
May be a bit naive on my part (over simplifying?) but is there a MAF sensor and/or TB sizing chart out there. From a novice perspective it sure seems like it would be a decision based on having a MAF and/or TB sized to match/support the flow of the intake and heads. If so it seems like there must be some sort of maf size to supporting flow type chart. Did a search and couldn't find anything. Found one link that referenced a pro flow web site but link/site returned "no site found".
Replacing stock intake to better match my heads very soon. Would like to better understand whether the need for a MAF and/or TB is in my future and/or whether I'd benefit from upgrading same.
If it is not as easy as referencing a chart how does one determine scientifically (much prefered over pure anecdotal recommedations) what the proper maf size is for a particular setup?
