standard air box clearances, how much cold air really gets to it.

16psi at 6500rpm sounds very good. Looks like dumps doing very good job.
What's your target max boost? Are you running stock ecu or ebc?

Stock ecu. Running 3 port tune. I'm looking at pushing the turbos next tune to maybe 20psi to see if outlet temps rise to the point it's just heating the charge. And that tune was on a 42*c day

Seems i may have found myself an ARC super induction box, should provide some interesting test results combined with my vented evo style bonnet to further add to these discussions. Going to relocate the battery and investigate some additional ducting routed up to it from between the intercooler and passenger side foglight.

I've looked at the pics in the first post about the clearance underneath the bonnet and it got me wondering. Has anyone thought about creating a custom snorkel maybe a bit wider and definitely taller than stock which goes through the slam panel to the grill? As in modify that section of the slam panel to be further down to allow the snorkel to slope down it to stay within the clearance which is like a staircase. I imagine this is a lot of work and maybe not advisable due to having to modify the structure, but it seems like a reasonably direct path which will look stock in the end.

you could probably do that but you still have issue with the snorkel having to go over the top of the radiator and under the bonnet. which still be very tight.

what you have to remember, there is a air con rad under the slam panel. the most direct route is something rikki has looked at, and cut a vent through the bonnet directly into the snorkel.

[kiwigalant]

Yeah and I guess you couldn't increase the height of the snorkel much because the bonnet might smash it when it gets closed and then springs up to normal height. But the air con condenser seems to only take up half the depth under the slam panel and nearer the radiator. Still not a lot of space to use, there just aren't easy paths out the front on these cars are there.

this is why i think people are going down the adding an extra pipe to the snorkel of dirct to the air box (before the fillter), both will have the same effect. i think the bottom of the snorkel is equally acceptable.
th bottom of the air box would probably be my choice but that is just personal preferance, however having an auto gearbox myself it might be to tight to get the pipe to fit in that particular location for me. i have a lot of other stuff in that location as well.

[Trotty]

Yeah this is what I've done.

[kiwigalant]

I'm guessing because many people are doing it that having air come into the box or snorkel from multiple directions doesn't add turbulence to the flow as such or is it just a by-product to a greater intake?

[scott.mohekey]

The filter will sort out any turbulence.

[AKKO]

Yeah this is what I've done.

Loving the OEM paper filter!? :-/

Time for me to find some piping, a funnel and things to mount them to the car with lol.

Yep and still making 210kwatw lol
