Default Lets Talk about Blow-thru setups...

What are your opinons on this, kinda just got to reading up on it and doesnt seem like that bad of an idea. The only part i dont like is the possibility of the Maf cracking from pressure. Anyone have a suggestion for alternate maf compatible with 240sx?

Z32 MAFs will work, but I'm not sure what you mean by "blow-thru".

settin up the maf to blow thru rather than pull. ie. place the maf in the intercooler piping.. i hear its suggested that you dont want to mount it near and drastic bends or turns

I've never heard of that. Why would you want to do that?

believe it works along the lines of bov atmosphere and not having idle issues, plus you dont have a ugly maf right before your purdy turbo.

you are correct.

We use a GM LS6 MAF, but boost pressures above 20psi tend to blow the coupling apart. Plus, the MAF itself isn't designed for boost pressures, and tends to leak.

On the good side, if you blow an IC coupling, you will still have driveability.


Just save up for speed density conversion.

This isn't always the case.

Why not just get a standalone and get rid of the MAF?

Yes, you will. The MAF is metering air AFTER the turbo.
