Anyone interested in using this huge maf to replace the denso sensor?
I was scanning the sema reports for cool new parts and came across this:
http://www.semadigital.com/netpub/se...49&site=np2008 http://www.abacoperformance.com/ What you are looking at is a new 3.5" or 4" MAF sensor that uses multiple flow sensors on both the front and the back of the flow stabilizer veins so that it can zero-out flow reversals and has a digital stage to smooth the flow data. What I am wondering is whether anyone besides me is interesting in seeing this thing used in a 500+ whp subaru. Unfortunately they want around $450 for one. Any takers? Frank |

It sells for $390 online, which is normal for standard aftermarket MAF.
I'm wondering about the advantages over our stock unit... |

Why bother when blow-thru MAF setups and speed density is proven on subaru's. You have to look at all the other high horsepower subaru's on here. Have any of them used this???? (None that I have seen) So why start using it now when our cars make alot of power without having to use that.
Sounds/looks like more of a PITA than anything. And for people that run bigger diameter intakes than 4 inch which some rotated turbos do it would taper for the MAf thus hurting flow. Plus this has to be wired into the engine harness plus tuned for if any tuner can tune these on our cars. Stick with what we already know works. bank that $400 they want for that MAF |

Blow-thru maf works if you have enough pipe run before the TB. I'm using a topmount and if I do anything different, it would be a v-mount with a reversed manifold. Speed density requires a map sensor and a different ecu- again not appealing given the aftermarket ecu options that are currently available for an '08 sti. I wasn't looking for anything larger than 4". This solution does seem to be proven already on Mustangs, BMW's and Porsche's. I'm sure this wouldn't be too much effort to implement. Frank |

If you're not trying to constantly improve and move forward you might as well be moving in reverse because everyone else is going to pass you by. I think its ability to filter out flow reversions would be beneficial to those with big cams that are still MAF based too. |

I think it does include an IAT sensor as well.
I'm hoping an intake builder picks up on it so the g/s to V conversion can be done once as I agree that this is a mild annoyance. They would also be in charge of establishing a direct to OEM wiring adaptor similar to what this company already markets for Fords and others. Plumbing shouldn't be any worse than any 4" intake.

There really isnt an advantage. The OEM maf sensor works just fine. You would also have to get a separate air temp sensor if you buy that Abaco one.

I don't know. If we all felt that way, we wouldn't have electric lights or these horseless carriages.
I'd love to see the op install one and see how it works. |

I objected to Fastlane's automatic dismissal of the idea BUT, I agree with him that most people don't NEED to use a MAF like this. |

I would think that seperating the MAF from the IAT sensor would be a good thing, although I am sure it would be a hassle. I am actually surprised that nobody has tried to isolate the IAT sensor and place it in the intake manifold.
I would like to see what Geoff from Full Race has to say. He seems to be a proponent of pre-turbo MAFs, and I know he has mentioned adopting a larger Supra MAF for Subies. |

I haven't really gotten a good read on it but, apparently the JDM spec-c manifolds have the IAT in the manifold (a bung on the underside). I'm not 100% sure of this information. I've just seen comments about plugging the bung though. IAT in the MAF makes no sense for a turbo car. Even my Civic had the IAT in the intake runner right in front of Cylinder #1.

Yeah, you're right. They call it an ACT sensor.
I was looking at this one. http://fordfuelinjection.com/?p=29 Wondering how much work it would be to plumb this into the intake manifold proper. |
