blkonblkMSP, if your trying to push over 12 psi i would go with 3 inch, but you can get away with 2.5. Or you can go 2.5 hot pipe into the intercooler, and up to a 3 inch cold pipe and the increase in size will make the air even colder. Also you can relocate the MAF without reducers.

The MAF is 2.75" so I would think you'd either have to go with some reducers somewhere (whether you're going with just 2.75" piping..) since the throttle body is 2.5".

good point metallic36, i would just stick with 2.5, and i think the i.d. is 2.75?

I like knowing that if I get in a front end collision, I wont die .

Ah, that depends on what you hit (lol2)
But yeah the foam thing may help some. Not sure if it up's the ante in your favor all that much.
Either way I have been smashing over 20PSI through this thing and it has no issues keeping the charge cool.

Not this MAF

Not only the foam thing, but the large metal beam under the bumper. It's nice to have it there instead of whatever hits your front end going through your radiator and pushing the engine/dash, etc. in your lap. But I guess there's just a number of us that still want that added security.

No.. I was basing my response on the stock MAF size, etc.

I do have a rather hefty steel beam that the core mounts to that is more rigid than the stock part so I don't think it will allow any more rearward movement than the original piece. However, from what I can tell it looks like the stock beam is meant to deform which would allow the material to move further back than the beam I have now.
It would seem that the goal of the stock part is not to prevent rearward movement but rather to absorb a portion of the impact. I can assume this would be part of the crumple zone philosophy.
And then of course there is the IC core itself which will "squish" being made from aluminum that looks to be able to absorb much more force than the stock not overly substantial styrofoam part.

I hope none of us ever have to find out how much our front ends can take Drive safe! (drive2)

Thanks every1 I went ahead and got 2.5 pipping from Metallic36.
