As i understand it...... there is less chance of the wire getting broken as the air, though at greater speed always travels in the same direction...... Prior to turbo it suffers more pulse issues.

does it affect performance in any way?

anything else? except possibility of venting to atmospere?

MAF induces air pressure drop up to even 0.2-0.3 bar so putting it after IC will allow your turbo to reach desired pressure quicker. I recommend this excellent article on eliminating negative boost:

Just been reading the Autopeed article, very good information!

I am also interested in the MAF after turbo, because of limited space for a grill mounted airbox / feed.

Would the mapping of the ECU be affected by the new MAF position, or not, seeing as the airflow should be the same? I will be getting the ECU remapped after the intake system is finished on my car so it is not a problem if it does need to be sorted.
