I am contemplating blow thru as well with an HPX ford style MAF. I am very interested in the data here.
Do you intend to acquire a MAF designed for this operation?

yes, I actually have a second hand pro-m but its garbage, its calibrated for a totally different setup within the actual sensor so no amount of tuning on my part will fix it. I intend to buy a new one and have it configured for this application
I have been meaning to buy a proper setup but decided to revisit stock sensors before doing so.

Please tell me more! I would guess the primary difference in a MAF designed for blowthrough is different operating temp compensation characteristics... anything else? |

I honestly dont consider myself knowledgeable with MAF sensors in the grand scheme of things. Mark at ASP turned me onto them because they calibrate the specific sensor. You can tell them what your peak intended airflow is, your injector size and how you plan to plumb it. They then set one up for you, they calibrate the actual sensor on a infinitely variable orifice flow bench and turn out a voltage transfer data sheet for your needs. People who have ones that are properly setup rant and rave about it being the best thing ever.
They make all sorts of maf solutions. I bought a 3" boost tube that was off a 3000gt running similar injectors, no dice. also the previous owner didnt pony up for the detailed voltage data.

Interesting. Can you have them flowbench your own setup? Or only theirs?

They say they can re-calibrate any sensor.

Interesting. I would be tempted to send in a stock hitachi maf in an 85mm housing... but what about intake tract? It makes a HUGE diff... airbox vs open element. Do you send them the whole fucking airbox?  Let me know if you think this is feasible; I'm willing to partially fund it. |

I honestly would rather just buy one of their standard offerings. If you look at their boost tubes (blow through) they are all 1 foot of tube and they say thats so that the air collects right. their pre turbo stuff seems to be specific also, they say that if you run a cone filter to send that in with your maf. I bet if you sent them an airbox they could do it up right. oh and btw http://www.promracing.com/ |

http://www.autospeed.us/they changed it a while back, mark slazak suggested pro-m. it seems mark knows jeff atwood (very skilled motronic tuner) who I am assuming is the son of bob atwood, who started pro-m. Jeff has made flex fuel and blow through stuff work good on the bluewater R32 and other cars. all those fueling kits spec out pro-m maf setups. something tells me that we have over looked a great tuning resource here... |

the x-axis for mlhfm is voltage, does anyone know what the y-axis is with the units?

I would assume the mappack is kg/hr. Have you checked it? |

yes, thanks for the heads up. the measurement is in kg/hr...

BTW all air flow measurements in ME are kg/hr... just a heads up so there isnt g/sec confusion.
