I was wondering if anyone would know if it would be more responsive if I had a 3" TID to move the air filter to the front of the engine bay, or to simply have an air filter clamped directly on the turbo? Thanks in advance!

 

No difference, unless you can get it out of the hot air from the radiator.

What about the AFM, or are you running a freestanding ECU?

 

don't think you can have a filter just clamped on the turbo without a stand alone engine managment system.

ooops didn't see your edit there sure shot, beat me to it.

 

Even if you don't have an AFM, clamping the filter straight onto the turbo is just a bad idea. It's the hottest place in the engine bay. Do you really want the engine breathing that air? The pod filter should be in the front corner of the engine bay (or in the nose), completely seperated from the hot engine bay and fed cool air from outside. This will increase power across the rev range and reduce the likelyhood of detonation.

 

Hmm good point on the cooler air. Also Space is a bit of a concern

This is my car with pics of the intercooler install. Yes I have the afm still but its been relocated to after the intercooler piping.
