geoff is trying out a blow through MAF on his S14. it's working really well so far, no problems at all
setup:
enthalpy's ECU, z32 maf as blow through in 3.0 in. charge pipes with 4.0 in. of straight tubing after, then a 90 degree bend and 6.0 in of straight with a 90 before the MAF.
Are there any HP gains to be had from this setup. If not then really what is it's purpose. Only difference I see is the maf reading boosted compressed air instead of air at atmospheric pressure.
You'll have quicker throttle response and you'll be able to vent your BOV into atmosphere... and maybe less wiring for some!
hmm. ive honestly never seen this setup...anyone got a close up picture of this? i want to vent my bov up through in front of my windshield...funnnnessss.... any disadvantages to this though?
i kno, but i cant see exactly what he did that makes this setup much different. i searched on it, nothing else on these forums about it. i just dont understand how it works. james u on AIM? IM me.
he moved the air flow meter from before the turbo to after the intercooler. this allows the computer to have a much more accurate calculation between the amount of air and fuel, from what it percieves and what is actually going in the engine at any given time... that's why you have faster throttle response because normally the air that is measured by the MAF has a certain amount of time to reach the engine because of the length of piping between...
not really... the air coming out of the IC is always going to be hotter than ambient so it may run a bit lean because the MAF is a heated filament... but probably not much... and the wiring required isn't that bad...

theres gotta be a way around that. i wonder if you combo'd a CAI setup with a larger, more efficient IC, if you could at least make it back to ambient temps.

um... well I don't think its that big of a deal to try to go to large measures to fix... its basically denser hotter air than ambient... (trying to think this out as I type) so in reality there is more air going into the engine but the heat from it is causing the MAF to think there is less...
how this differs from running a MAF on a normal hot day is that on a hot day the air is not compressed...

i plan on running an aquamist water injection setup (distilled (aka boiled) water is cheap enough that i can run it 24/7. that supposedly can lower intake temps as much as 30* F

doesn't matter as you'll have to plumb that in after the MAF... you don't want to spray water on the MAF... you'll still be running a bit lean...
I like my MAF where it is.
Linear Mode
