I am guessing Robert was thinking about the 8/9 MAF setup and not the X.
Regardless, Shane knows what's up, I will get a 3.5" one and he can scale it. Bam done.

The physics are what I do best  The maf sensor is calibrated to be installed in a 2.5" tube (or whatever size the interior diameter of the stock maf housing is), and the cross-sectional area of that tube. The bigger the tube, the more cross-sectional area, so it has to be re-calibrated to match said tube.
As far as running a 4" intake to a 2.5" inlet, it's been done for years with no ill effects. Your lowest pressure point will be in the intake, generating vacuum from the outside air (thus the sucking sound) and then as long as there is a smooth transition from the 4" intake to the 2.5" (?) intake on the turbo, the compressor wheel will do everythign in its power to just suck in and swirl the air as much as it can. As the air approaches the blades though, it will probably be straight.
I had a FP 4" intake on a bastard20g turbo w/ a 2.5" inlet on it, they made a crazy coupler just for DSMs. It was like $35 but it fit perfect and was a pretty smooth transition. |
