I plan on doing a blow through setup once i get my build going and i wanted some answers from the tuning guru's as to what EM setup would be best? I was planning on going with the AP and from what i have read it should work perfectly but i just wanted to get some other opinions.

Thanks

I guess im entering into uncharted waters

Not in the least.

Thoroughly charted. You just need to read up.

Thanks, ive been searching and it seems to be hit or miss on what i find.

There are a lot of discussions about what it takes to get the MAF happy with regards to airflow and placement.

Beyond that, air is air.

Ok so basically it will work fine as long as you have a consistent setup that allows for a steady stream of airflow? The few threads i have found over the subject just had a few people chime in with no solid information so i appreciate the info.

It has to precisely replicate the OE arrangement in diameter and flow direction.

The i.d. must be 3.375" and the MAF must center exactly in the tube, which must have at least one flow-straightening screen 3" before the MAF.
The tube may not change direction or diameter within 6 " of either side of the MAF.
The air cannot exceed 180°F and/or 480 g/sec total flow.

Thank you, exactly what i needed. Just need to make sure i dont get a turbo that flows more then 480 g/sec

Heh. Quite a design consideration, isn't it?

You can also replace the MAF with something else and rescale.
You had better know what you are doing, though. Otherwise, you are in for endless headaches.

I really just did not want to have the MAF located under and at the very rear of the car, but it may just be the better way to go about this. I was planning on going with a Precision SC61 and that thing roughly flows 65lbs/min which comes out to just over 500g/sec... The previous cars i have boosted were alot easier to tune and the MAF's could handle a decent about and were not as picky as the 8's. Thanks for the input and im going to talk to my buddy at cobb hopefully this weekend when i go in for a baseline dyno.

What is the max voltage the MAF puts out?
Is that at 480 g/s?

i plan on mine to extend the maf to the rear.
im in the process of checking the readings on the extention to see if it will affect with the volts/watts/amps/ohms etc ill let you know how it comes out

Is the 3.375" diameter a requirement of the MAF to be accurate? I always thought one could use a larger diameter intake and rescale the MAF so you could have a higher total flow limit. Or are you concerned about the MAF being inaccurate at low flow rates?

The issue could be getting it in the exact centre of the airstream otherwise I can't see why that would'nt work

If I wanted more MAF flow (hint, hint) I would build and oval pipe section with a minor diameter of 3.375.
Solves both issues.
