Your MAF may report different voltages after the air has been straightened, though, and those voltages may change differently through the RPM range.

That's why he would have used fuel compensation to even it out.

Or it may be identical, who can say without trying? haha

Edit:
To clarify what I mean, lets say that @ WOT you start at 1.2v around 2k RPM and by redline you're reading 4.6v.

Then you straighten out your airflow and now you're getting 0.9v at 2k RPM and by redline you're at 4.8v. Because the turbulence compressed your delta V over the rev range, and now that the turbulence isn't there, you're getting accurate flow numbers.

But because your tuner set up your fueling tables based on that 1.2v-4.6v spread, you've got inaccurate fueling data throughout the rev range. See what I mean?

(this is all theoretical, numbers picked at random)

also, if you are communicating with Stillen...can you see if they have the dimensions off hand?

Okay, here it is. My SC is on the table, wiating for boost pulley.
2 Inlets on the Y:
Inside Dia 2 1/2
Outside Dia 2 7/8

Single outlet on the Y
Inside Dia 2 5/8
Outside Dia 3

Reducer Boot from Y to SC intake:
2 1/2

SC outlet:
Inside 2 3/8
Outside 2 7/8

Intake tube from SC to Throttle Bodies:
From SC side 2 5/8
From (2) throttle body side 2 1/2

Of note, the center of the MAF Mount is 2 inched from the K&N filter. If you need more let me know! Hope this helps..

Thanks for the info I decided to contact saxonpc the website for the honeycomb to get their advice on the right size to order. I will let the forum know when I have a response.

Just noticed this photo of the AEM ETI Intake System. It has the same proximity of the MAF socket to the airfilter as in our Stillen SC kit.
Gotta wonder if any one with the ETI Intake System can comment on whether it has the same troubles as in our kit.

So, is your kit brand new? If the kit is just out of the car for mods, what year did you order it

Mine was used and sat around for 2 years on some guys shelf.. It is a V3 SC the older ones are V2's. My Y pip is completely open.

I have looked at some cast aluminum 8 inch tubing. I was thinking of chopping it in half and welding 4 inches to each side to extend the intake side of the Y. KellyeFields made a nice shield our of some flat sheet Aluminum, I might do that to if the factory shield isn't working. Will bring it to the Dyno.. I cut out the fins inside of the front bumper. I got nice access into the that area.

well, i could probably get them to you sometime next weekend if you want the honeycombs i have

Matt,
Sent you PM

Do you intend to use the honeycombs? Even the Stillen engineer I spoke with thought it might be a good idea. Maybe Osiris will sell you his. If the Stillen engineer is right my problem may have nothing to do with the Y-pipe intake. And you may not have any issues at all. Stillen has been selling these kits for years and there are not a ton of people chiming in here.

Just thought I would mention that other than this truly minor drive-ability issue the kit truly has been awesome - totally changed the character of the car.

I would like too, but I am lacking funds until I get some UMA Fenders sold.
