If you cut the air box this maf housing will fit with a piece of 76mm silicone hose.
Then source the stainless and hoses to complete, Mine will have an elbow
tigged into the 45 elbow for catch can fumes

Just waiting on some more t-bolt clamps to arrive and Ill be fitting it
My new airbox lid should be cut next week hopefully

@ Paule how much you think MAX can be skimmed off the MAF housing
1.5mm max

[Paule]

Yeah TD I think you could open the ID up to 74mm no worries as the OD is 80mm. I just think 74mm ID is too much and will affect your low down performance.

From looking at mine I think it was straight through the taper is on the outside. The area where the MAF is located is thicker. I can check mine on Friday if you need exact.
I am running 17psi now with no issues.
How did the stainless end up?

Hey Dinger did you get the exact dimensions from you hpd maf housing on Friday? I'm thinking of just opening up the area the maf sits in. So 72.5mm inlet, 73mm where the maf sits. (maybe more but I'm just going a little bit at a time) 72.5 out let

Once I've fit it all up and it runs ok I'll put links to all components needed to complete for yourself.
Cost wise its about $100 no more, and that's for the
stainless elbow, 45, silicone hoses and T-bolt clamps,
most is easy to do, except the hole for the catch can hose.

Not sure you'll be taking much material from the OE MAF housing it has very thin walls.

Sorry guys I didn't get the info for you.
If either of you still need it I can get it later in the week once the weather clears the rig doesn't fit in the garage.

This will be my plan "B" the 76,, elbow will be tig welded to the plate,
after I have shaped it to suit the air box, but looking at my intake I dont think it will be neccessary

I may use the airbox lid with the OE maf as I think I'll have plenty of "EXTRA" air flow

Can someone explain why this would work better than an OE lid????
Low radius elbow cant see how it can "flow" better
Still like my lid better so far , thats if it works,, lol

I think I can source an OE lid and glue the 76mm elbow to it,
that will make it the same as those $450 jobs,,,,,,,, well similar

Edit,,,,,, all my 76mm and 50mm T bolt clamps have arrived,
or constant pressure. Also my 3/8th M/F stainless steel elbow arrived so I'll get that
tig welded in for catch can fumes, I could vent it to atmosphere but
back through the motor is fine, and will add a bit of detail to the new intake pipe
The catch can lines will be AN10 braided hose with black hose ends

Nearly there just need to tig weld that elbow, I have two different 76mm 90 degree elbows to use .
One is a short radius as pitcured the other is a long radius, hopefully fit it on the week end

Are you going to do a before and after dyno run , I reckon it would be good if you could , to give people a accurate idea if this is a worthwhile modification for dollers spent vrs results ?

Then he's gonna make one for me.
