What in the world made you think this kit was a good idea?

I'm running a strong 350bhp on a 3" VR6 MAF and haven't pegged it yet, you'll be fine.

The 4.2 V8 MAF is capable of 1500-1800 kg/h depending on which one you are using. There is pretty much never a reason to put it in a larger housing.

 Since prj is still keeping his Speed Density patch to himself I do not agree with you! Perhaps we can hope for some more info about pulsation handling and filtering soon. I don't think prj would loose business from revealing a bit more. I guess he has enough work to do every week anyway. |

Are you moving more than 1796 kg/h (498.89g/s)? If not, leave the 4.2 MAF in the 83mm housing. |

Of course it's better to not scale if not needed but if you have much WHP, the oem 4.2 housing is too small. I mentioned speed density since we wouldn't need scaling at all if that was available. Up to 4.2 MAF, no need for scaling. Above 4.2 MAF limit, use speed density without MAF. |

So should I just go with a vr6 maf with vr6 housing or go with 4.2l maf in a vr6 housing?

whatever you have a correct table for. If you can avoid scaling do so. That being said, a well scaled table would work fine too.
I'd try to avoid 4.2 in vr6 but I don't know limit of vr6 in vr6 housing and if that is enough for your goals.

I have decided to purchase a 2.7t Bosch maf that is in stock housing which is 3in. Now I'm waiting on silicone 3in to 4in hose to come. Car is running fine on my tuned file except I have 0 boost? How is that even possible? I hit like 2 psi and this is nothing hooked up except just spring pressure? How is this possible? I got injectors scaled decently so I thought i would try and see how some boost feels. But nothing  Tested external waste hate and no tears and when I apply air the valve moves so I know its good. Next i tested my diverter valve, it's good. How is this even possible! |

I guess I'll be making a 4in coupler to go over the turbo and boost leak test it. Crossing my fingers
