Default Looking for a 88mm ID MAF Housing...

Any place I could find a 88mm ID MAF Housing that would fit (or almost fit) the stock airbox? 83mm is not sufficient and 85 is just ~5% bigger...

I think I'll end up customizing one from scratch from somebody working at Bombardier Aerospace...

Default The stock airbox outlet is ~78mm. No 88mm MAF will mate cleanly without modifying the airbox.

Are you actually maxing out the sensor in an 83/85mm MAF?

Yes. 83mm was almost maxed out with K16... now with K24, it's 100% sure...

Default Stock or modded airbox?

The smaller diameter of the airbox outlet will artificially inflate the MAF readings if its smaller than the MAF inlet diameter.

You'd be surprised how much difference the airbox inlet (or any other step in the airflow) will make to the MAF reading.

Default I've got MAF housings available, but an 88 isn't going to be a direct fit for the stock airbox

If you're interested we can work something out with your K04/24's.

Obviously, it will require some weekend-craftwork cutting the airbox (Sponsored by JB Weld)

Default When does the stock intake system get maxed out?

You can only move so much air through the stock system, sure you can use a larger maf housing so your MAF sensor isn't getting maxed out, but the stock plumbing can only support so much airflow...yes? no? With these larger turbos won't there be a certain threshold where the internals have to be upgraded to support more air mass? Or am I looking at things incorrectly...

Default I don't think the diameter of the intake system is ever a limiting factor (even with K04/K24s).

Instead the electrical limit of the MAF sensor itself comes into play. By moving the sensor into a larger housing (and scaling fuel appropriately), you effectively increase the sensor's range by making it read lower.

Default Mike Moore is the perfect example of a big NO to that quesiton.

He has absolutely no mods to increase flow. Not even any port/polishing or anything and his car could easily max out his 83mm MAF.

Does he max out the sensor in the 83mm housing?
