Evo X upgrades

I've got an email into CBRD and IveyTune (ETS' suggestion) to get an opinion. I'm thinking I might need a 3" inlet upgrade on the turbo and a custom 3.5" intake. ETS figured they could do one but they'd have to source a flange and it'd take a few weeks if they needed to machine one.

My build is breaking more ground than I wanted or expected. lol.

Might wanna check with Bryan@GST and see what he's using on some of his BBX or FP Red E85 cars, he must be near that threshold as well (might just be included in his posts about them). I would just have DB mod or make you a 3.5" intake and be done with it.

I figured I'd gather data for a day on the national forums but I'll ask DB what they can do, first.

That and some welding. If it'd result in more flow then you could cut down the 3" AMS pipe or use the stock plastic MAF housing with a larger pipe behind it. I'd want to leave this to Shane, Primo, or whoever can do it...the last thing I want is to homebrew something that Shane can't get to scale. I've heard that 4" pipes will not work with the MAF but I'm not sure about 3.5".

The thing is, the turbo only has a 2.75" inlet. I never took fluid dynamics or whatever so I don't understand how a bigger pipe in front of a small inlet works out. Is it because the turbo is sucking?
