Afm Thru Intercooler

[mad082]

^^^ Yah it will, as the AFM isnt seeing movement due to BOV when you back off.

that depends on where it is. if the bov is after the afm then you will still have the problem as all the air in the system will go past the afm and make it run rather rich.

The second positive being less restriction before the turbo so you may get some free power.

but you are adding restriction after the turbo so you negate any power increase.

has ne1 actually done this? coz i dun wana stuff up everything over a couple of bucks

i have seen a 33 that had it done, but the way that they had set it up added about 1m of extra intercooler piping. they had it after the intercooler (hybrid style) and had the cooler pipe run up the from where it came through from the inner guard, then up to the back of the engine bay (the afm was in this section of piping) then a big loop around the back of the plenum befofe going into the plenum.

Apologies, I thought the intended meaning of I.cooler > BOV > AFM was quiet obvious

but you are adding restriction after the turbo so you negate any power increase...

If i rem my physics correctly, a restriction in a pressure scenario, is less of a restriction then

if so in a vacuum section (all other things equal of course)

Plus, the slightly hotter air would flow around the AFM probe easier no?

…you may have some mixture problems. As the air is denser coming back from the intercooler.

I have thought about this previously, and would suggest that the max air temp going past the AFM and into the plenum, wouldn’t be that much hotter then through the AFM of a stock setup on a 50degree day.

If the density being read was an issue, wouldn’t it crop up in the stock setup, where the AFM in front of the turbo see's a greatly diff temp (density) then that, that enters the plenum?

Hope this helps, these are my corrections to your theory that Ill believe until corrected

1 question. why did this happen.....

a friend of mine tried this dose pipe thingo... it sounded pretty awesome. but made his car very sluggish. a civic could probably beat him AND it would cut out on big boost. )15psi not big but big enough for a stock turbo. we went to certain VL mechanics and renown ones too... and all said it looks pretty normal and the problem was the afm was too sensitive.. we even changed the afm but it didnt change. so unless we done something wrong...

my advice is dont do it unless u have a aftermarket computer and u wouldnt have to put the afm just a pipe off the turbo IF u want to do it. if anyone does know a solution to why his car started to run sluggish it would be great to hear about. thanks
