Blow through or draw through?

[agile30]

For the mass air flow sensors. What are the main differences with the set ups? Pros? Cons?
Just reading around and it seems like the tuners sell the blow set ups with their tunes. I have a friend who has an emulator who will tune the stock ecu. But Im not sure if I should go with War/TRM for tech support wise.

What do you use?

ideally speaking there are two types of blow through Mafs. Im assuming you arent interested in air flow meters as MAFs are usually more efficient anyways. The two types are hot wire and hot film. Both work essentially the same. The best way imo would be IAT and a map but im not sure if WAR will support that

well lets say the stock maf vs war maf vs trm?

I'm assuming this is for a 24V engine, the stock maf is good for draw through only not for blow through.

Sorry for seeming like a retard but...... your able to use it then for a turbo set up without running into issues or will running it on boost fuck up the flap on the maf / cause retarded readings?
What did you run on your euro 24v? Yea its going to be a set up on a m52.

Well the maf has no flap so your good there using the stock one for a draw through (maf in front of turbo).

My euro was draw through with a recirculating bypass valve, it's a blow off valve but it doesn't blow of to atmosphere, it recirculates back between the maf and turbo.

Are you just boosting the stock compression engine or adding a MLS and ARP's?

Mls and arp. Plan on running 15psi maybe 18 depending on what tune feels right in that range.

Then you deff want a blow through set up, contact TRM, they are expert tuners for turbo charging.
