Maf before blower?

[MYSHO1]

Would it be better if i put the MAF before the blower if i run the blower RIGHT next to the intake?

Ideally, it would be best to put both the TB and the MAF before the blower.

In reality, it's whatever you can get working best!

V8 wise, the MAF AFTER the Blower is a nightmare. I did this.

As the Blower spools up it creates variable vortex's in the intake pipe. Think of a drillbit. It has a spiral shape. The vortex created in the intake tube is similar to this. As the Blower output changes, this spiral changes positions. You get the MAF set for Idle and then hammer it, the vortex MOVES and the MAF Freaks out. You CAN'T tune for that very well, In my experiences.

My next blower project has the MAF and Throttle Body in the stock locations, and on the Intake side of the Blower. Should behave much better than Mike B's car did.

Ideally, yes, especially if you're utilizing a draw-through MAF (like the newer 80mm and 90mm Lightning MAFs) that may not take kindly to being placed after the blower in an otherwise blow-through configuration.

I assume the blower in question will be driven by an FPS-style jackshaft?

No i have something else kind of in the making...

FWIW, SCT makes two 90mm MAFs that can be used in either a blow-through or suck-through configuration. They have a OBD2 style connector like the Lightning MAFs, but nothing a pigtail harness won't fix.

The 1453RWHP Ford GT TT runs an SCT BA-2800 MAF in blow-through with no *******.

Chris has just brought out an important point which I neglected to address in my original reply, and that is to make sure that you utilize the appropriate MAF type (draw-through or blow-through) for your particular setup. Failure to heed this warning - say, by utilizing a draw-through MAF in a post-blower, blow-through configuration - could result in difficult tunability and other driveability problems.
