New air box and oil catch tank piccies
Discussion
Your right Daz. Doing it the way you describe the engine will still suck the gases out and catch the nasty oil. This will prevent oil seal problems as the crancase will still be at negative pressure as standard.
You can though vent to atmosphere as Chilli has done. I think if venting to atmosphere you are best venting both covers. This will help with potential leaks as there is no induction pulling it out.

So two flame traps connected to the catch tank ,one each side .Eather to a T piece or in to two connections on the catch tank.You can though vent to atmosphere as Chilli has done.

Both must vent in to the top of the catch tank and any residue falls to the bottom ..Seen some catch tanks which have a dip pipe one side which would be no good for this application..!
O a standard setup what does the pipe off the flame trap actually do .?
Chillies near side bank must still be relying on that little breather thing ..

Nuther piccie of the airbox
Er, sorry, blatent plug for FastEddie
So why is the aluminum one better ? looks the same to me ,prefer the look of the carbon one !Er, sorry, blatent plug for FastEddie
I would of launched the hoover hose and fitted something smooth ..
Can`t see the point of insulating the hoover hose then leaving the aluminum air box ..That must absorb some heat ..
just can`t see the point of all this !

Well, i am here.
Chilliman has passed on very well what i explained i have done.
ACT plenum had 75mm inlet to match up to 75mm flexi and filter. This was a restriction proved by the fact that Pipercross do the filter fitted rated at 360bhp whereas the exact same filter with a 75mm neck is rated at just 290bhp. The new collector has a slightly larger volume that the ACT one too
Hose is motorsport grade smoothbore twin skin flexi rated at 300 deg C. Doing in hard tubing would have meant alot of cutting/shutting as there are a few subtle angles required to run close to inner wing and down to front.
I ran the engine with the hose bare and the heat soak on the intake pipe from the collector/cat area was severe as there is less than 50mm clearance with this larger bore hose so i insulated it.
Original filter was placed right close to the top of the rad out of any air flow and the original flexi was having to do at least a 120 deg bend. The distance from the filter to the throttle bodies was very long and with the restriction must have lengthened response.
On the breather, it is the one on the off side that is connected back into the intake where the massive vacuum was just sucking loads of oil vapour back in unnecessarily. This now goes to the prototype catch tank whick has a condensing plate in then a vent to atmosphere. We will see how much this collects and adjust size and add drain/sight pipe if required.
Was not the ideal wether for testing and with the extra air hopefully going in it may be running a little weak up the top end so we await mapping/rolling road figures.
Cheers

Im running a standard plenum with a 72mm disc and full ACT induction kit ,the airfilter is a K&N ,will this be a restriction ? my car is dynode at 340hp ..Chilliman has passed on very well what i explained i have done.

If it is a restriction what are the options .. what about a larger air filter or something like this .
I have one of these
