maf that flows 1000 cfm

[Yves]

Is there a maf sensor that flows 1000 cfm.

My understanding is you can pull the little sensor pod out of any MAF and put it in a bigger pipe and scale up the cross sectional area to find the new flow curve.

for instance, if you have one in in a 2.5" tube, pull it and install it in a 5" tube and scale up it's CFM reading by x4 and you're good.

Would need to stay at 3.5-4" diameter max.

I don't know any of the specifics about any of the MAF sensors, and definitely not any European models, but they can all be scaled up with a new larger duct if you have some fabricating ability. This can also let you clean up under the hood and not have as many rubber hose junctions.

So far, I've ran everything SD

Check with PMAS - they've probably got something: http://www.pmas-maf.com/hpx/

Great Matt, thanks for that link.

A question : I have a SBC V8 with crossram ITB's. Each cylinderbank is connected to an airbox above the valve cover on the opposite side. Currently the air feed into the airboxes is from the front, where I attached a 3.5" tube to a cone filter. I was contemplating on using a box in front of the engine where the 2 boxes connect and that houses a flat panel air filter. I then would connect a tube with MAF to the fresh air source in the front of the car. There would roughly be about 1 foot of tube + the airboxes between the maf and the cyls.

Would this cause the reaction of fueling to be too slow ?

I'm still unsure if the reaction of the ecu to changes in maf would be too slow because of the distance.

I see that on vehicles the likes of Ferrari 348's for instance they use 2 mafs and 2 ecu's. Did anyone ever try that approach ?

You'd want to use the TPS or MAP for acceleration enrichment anyway.

I did this to scale the airflow past the element. The element is plumbed into a 3 inch OD steel exhaust pipe as intake plumbing into the Turbo.
