MAF sensor placement when boosted

I know some people have their MAF sensors in different places and I was wondering what the optimal setup would be. Do you think it should be on the intake air, or the compressed air?

my vote goes to intake air.....too much compressed air will damage the MAF.

I think that's why Stillen change the MAF location from compressed air to intake air on 5th gen max.

I second that vote. If you have a 5th gen I have a good write-up on that on my site

Well lets put it this way, take me for example, I decided to put the MAF on the charged piping side to avoid BOV stalling problems. So I dynoed at 10-11psi and ended up blowing the MAF on the dyno during the run. So for a FACT on a 5th gen you cant run it efficiently on the charged piping side.

Now on a 4th gen I know for a fact it is fine to run on charged side, every 4th gen s/c kit is built that way, take MardisGrasMax, he is pushing well over 430whp and still aint blown the MAF from being on the charged side.

I think mardigras uses a pathfinder maf tube and sensor, IIRC.

That is because of the larger tube diameter to get more boost in there without any bottle necks happening up near the throttle body.

Thanks for the help guys!

Does anyone know where I can get a Vortech (or similar) blower for a good price? I only need the blower.

Thanks again

Dixit : I think Mardi's MAF can hold up the large amount of pressure because he uses a pathfinder MAF.

what happened to your blower?

a brand new one is 1500. I just checked ebay....didnt find anyone selling just the blower.

Hmm! I warned people about this problem a loooong time ago. Too bad someone found it out the hard way.

I never disagreed with your initial statement when you made it months ago. We all know who WANTED the maf on that side. Its obviously clear where it can only be.

Mardigras uses a stock 4G maf that was ported for a little more flow.

you mean pathfinder throttle body.

I understand the stalling issue, but I don't get it from there. The air pressure should be the same in both pipes shouldn't it, regardless of what side the turbo is on. I mean, the air that is pushed by the turbo in the charged pipe, is pulled by the turbo in the intake pipe. Does the same exact amount of air not flow over the MAF regardless of where it is installed? I wouldn't think that the charged pipe is any more dangerous that the intake pipe. Someone please explain this to me.

does that help in avoiding blowing the MAF sensor under compressed air?

oh~ is it the throttle body? I thought he uses pathfinder's MAF tube.
