I've searched and can't find this info. Does anyone know what these units will flow in cfm? I'm talking the factory maf like what would be installed on an 03 Lightning.

I have been told that the stock ford 90 MAF pegs at 5.0 volts at 1750 KG/HR wich is roughly 475 hp. However the meter housing itself will flow a whole bunch more than that.

The SCT BA 2800 MAF do to come out soon is rated at 3150 KG/HR before it is pegged and is good for engines making over 650 rwhp. The SCT meter is almost identical to the Ford meter in size. Dale

 

Thanks Dale. What I'm trying to figure out is what cfm it will flow. There's aftermarket upper manifold/mono-blade tb combos coming out that flow over 1100 cfm. My question is if the stock maf flows that much. If it doesn't then it doesn't matter if the intake does.

I know with a centrifugal I had that you do NOT want to restrict the intake side of a blower. I actually lost over 300 rwhp on a ProCharged big block when I put a mandrel bent 180 degree inlet pipe on the blower, trying to do a cold air inlet system.

So I am interested in one of these manifolds and throttle bodies. Problem is if they flow 1100 cfm and the stock maf only flows 900 cfm then there's little to be gained. They talk how the stock manifold and throttle body only flow 850 cfm but I'm wondering which is the weakest part of the intake package, the manifold, throttle body or the maf.

If Dale's info is correct, that means that the stock MAF hits 5 volts at 904.9 cfm, and the SCT unit would hit 5 volts at 1628.7 cfm.

Are you sure that it's the BA-2800 you have info on Dale? I've only heard of the BA-2400, which SCT quotes as supporting 650-675 rwhp in a suck through eaton/kb/whipple application.

I believe that the SCT unit is a 90mm Hitachi MAF, so there's no real physical difference in what it can flow and what our stock MAF can flow. The electronics are the only thing limiting it.

I have the numbers for the 2400 but left them at work, I am positive of the numbers on the 2800. That info came from a person at SCT. I can post the 2400 numbers on wednesday if you want.

I would appreciate it. Seems like it may take a maf replacement also to take full advantage of the new intake/throttle body combo.

I thought that SCT was making 3 different MAF sensors, each flowing a different amount of air.

 

The SCT BA2400 unit is supposed to be used on engines making 400+hp and will max out at 2630 KG/HR
