Another pull-through vs blow through
I will post up sheets as soon as I can, but we dynod a stock bluebird setup on a DE today. On 10psi the blow through was around 160whp, the pull through made more power on only 9psi. By how much??? You won't believe it when you see it.

Draw through makes more power then blow through on a DE maf with no tuning It is possible to tune it out with an safc apparently, but the maf voltage is inconsistent on the de maf running blow thru. This causes the computer to dump fuel and pull timing. IF you have a de maf, do not blow-thru without a supplemental tuning device.

The motor has issues if it only made 160whp on 10psi.

The turbo is bad 8O.

It was a simple swap, from one setup to the next. Blow off valve was stiff enough to not leak under boost. And this was on stock MAF. The numbers show what they show on this setup. Stock bluebird setup with calum ecu and fmic. Stock exhaust.
