I noticed in the newest SCC that their Turbo Matrix had a wierd setup. They actually had the mass air welded into the intercooler piping after the bov so they could vent their blow off into the atmoshpere. After reading this it makes perfect sense and I wonder if anyone else has tried this. It seems a lot cheaper than a S-AFC and you don't have to tune it either. Let me know what you think about this for our cars. I am going to my exhaust guy and see how much it would be to do this. It's a great way to have the nice bov sound.

Problem with that is intake air temperatures. Stock MAFs may not live very long exposed to that kind of heat, let alone be accurate. Did they use the OEM MAF sensor with the turbo kit, or is it a special unit?

All of this effort to get a stupid noise to come out of your hood. :confused:

This is also bad...b/c the MAF is succeptable to reversion pulses when you slam the throttle plate shut. Nice observation..but bad idea..

How come there were no complaints from any of the editors? The company who put this together was XS Engineering and they know their stuff, so why would they do this is if it was bad?

I never said it was bad for them, I said it's bad for us. Our MAF sensor simply wasn't designed to take that kind of abuse. Who knows what kind of abuse that MAF sensor was made for? Can you tell me, yet, whether that's even the stock MAF sensor? The odds are against it.

Upon calling XS Engineering they said it was the stock MAF sensor and it should work just fine on ours also. I take it no one has tried this yet?

You don't want to have MAFs under pressure. The wire is pretty sensitive and should operate under vacuum only.

bad idea, our cars have a wire MAF sensor, the sensor on the Matrix is different, is is a small unit, I just read that part of the issue as well,

Call Clark at Jim Wolf Tech.. www.jimwolftechnology.com and ask him.. It's been tried before and like I said, it's not designed for that and reversion pulses would do strange things to it. Call them though...they are the pros at Nissan..

Why then may I ask, that maxima guys with the vortech blower, use the MAF on the pressure side and not the vacuum side? It seems to work fine for them, seeing as I have NEVER seen it on their cars otherwise. Am I missing something?

Also are the z or q45 or cobra mafs any different from stock that would make this work?

I just saw one of the import mags that were trying to make the Stillen setup work worth a damn for the Maxima. Stock, the kit gave about 30 more horsepower as delivered. One of the things they did was convert the MAF to a blow thru configuration. After having problems and pointing out other Maxima MAFs have died with that conversion, they switched it back to a draw thru configuration. I THINK it was Turbo magazine that had the article.

Like I said..call JWT.... I know from experience that it doesn't work on our cars..
