So currently I have my MAF way too close to my top mount turbo. I am only about 8" away which I was told needed to be extended to 18". I don't think I will have the room to actually make that distance so I am trying to come up with a solution.
Someone mentioned to me that I might want to try moving the 300ZX MAF over to the throttle body side.

I thought I would get some opinions on that and possibly other suggestions.

I am down to this last issue and I want my surging to go away.
Thanks
Here are a couple of shots of how I have it now

 

how does your car run? If it stutters, then yes, move it further away (the turbo may be causing turbulence in the intake and the MAF has a hard time reading correct amounts of air), if not there is no reason to relocate it. Moving it to the throttle body side would make it a 'blow thru' setup, research it because Im not sure how much boost a plastic MAF can take before shit inside of it blows apart (this also depends on how much boost you want to make). Other than doing blow thru it is pretty hard as you know to get an 18" span between the MAF and turbo. Maybe switch to a smaller mushroom shaped filter and have your intake dip down toward the front left corner.

EDIT: BAH! just saw you had surging issues. I take that to mean your car falls flat on its face sometimes or stutters?

 

Yes it sure does, and it is getting old. I do want this problem to go away. I see your point about moving it to the TB side, I would say my boost would cause lots of stress on it. I could be wrong though.
It just seems like I am limited for space to get the 18" after my turbo but I have to come up with something.

 

i thought about running the intake through my fender like the hotpipe and putting the filter outside the car but that is really suspecting it to water and shit. Curlicue shaped intake Any room to run it between the radiator and engine towards the throttle body side? I would of done that with mine but can't due to my stock clutch fan being all up in the way.

 

Might be a little warm there but I do have the FALs blowing.

 

What about doing something like some of the Supra guys do:

Shitty picture but you get the idea...open up the hole for the hot pipe and run your intake pipe down there closer to the front duct then re-route your hot pipe to come in from the side. Lots of cutting and more pipe fab but if you could get away with that very easily, and you'd be getting a lot cooler air coming in too. Or you could always do the standard move by coming off the turbo and making a 90* left to run in front of the motor. That'd give you your 18" there too.

 

Those are good suggestions, I was just a little worried about the filter and MAF being down in the wheelwell area where it could get wet

 

Adding bends is just as good as adding length when trying to combat mafs turbulence. Just mock up a 90* mandrel bend off the turbo towards the fender, and then a 90* coupler from there to the mafs so it points forward. See how that does, then weld your valvecover vent back on afterwards.

 

Do you think the heat from placing the intake right behind the radiator or anywhere hot for that matter will make much of a difference? afterall that air is being pumped through the turbo that is at ridiculous temperatures. Im not knowldgeable much in the physics/whatever category but if you pull in air that is 120 degrees and heat it to 400* it would be the same as pulling 80* air and heating it 400* right? So no matter where the air comes from it gets heated to the same temp? Makes 'logical' sense to me.

 

thats why I mentiond curlicue intake. But just as you try to minimize bends in your intercooler piping should the same hold true for the intake? then again, if it fixes the the stuttering who gives a poop. haha
