If you want max g/s then go for a metal guaze filter rather than a cotton one but filtration isnt as good.
Big figures, there. I'm fairly sure MAFs can over-read as well as under-read, but I'm not saying your figures are wrong.... but much higher than anyone else has ever managed...
However, I came on to post that when I ran the stock airbox plus green filter with a big air feed, in the end I left it with the air feed not connected to the airbox, air feed pointed to the airbox opening but leaving a gap.
I can't remember the figures, but I remember that it is was significant. I felt a detrimental difference in not having pressure in the airbox, but higher g/sec at the top end.
Hot air from the engine bay? Don't really know. Not while you're moving, I wouldn't have thought.
Edit: P.S. a couple of blue leds behind the holes in the sheild, and that would look "bitchin".

LOL @ the blue LEDs
The two sets of logs were run within days of each other so I'm sure they are comparable, but like you say it could be over Reading. I like to keep an open mind.
It feels so different that I'm sure there is a gain there, we will never actually know (because I don't have time to waste to put it back how it was) I'll just try to believe they are correct

phil, working it back from injector duty and rounding down the afr it comes out at 232gs
I've never had idc that high before but if you told me you could gain that much from fitting an air filter, I'd still laugh at you

Those maff readings are correct and accurate as your boost levels support the air mass figs.
Can't wait to see what the new filter makes.

The dynatwist cone used as a general cone out of its housing flows poorly compared to the other cones i've tried, but its tapered particuarly narrow to be most effective to allow good flow for air being directed to it from below in a housing. When plumbed to the stock air position the readings were poor also but i've since realised that this area is not presserised at all it just allows the filter to draw cool air rather than be ram fed.
So this week end i will ram feed the dynatwist and then latter get my axe on it and modify it like Probee.
Probee have you seen the Dynatwist XXL considering we are using only the XL version, its rated 100 bhp higher than the XL so must flow better too.

Forgive my lack of knowledge but surely its not all about air flow but the temperature of the air going in the car? No good have lots of air flow if its hot air?
I think this is why Probee hit the jackpot because of his twin cold air feeds from the fog lights feeding his modified dynatwist. Only problem i got with the dynatwist design is the metal used...surely thats a magnet for heat?

That's a good idea, I would like to see how this new filter does first though. It should give better airflow it's a much bigger filter.
Have you got logs of your setup now since getting your SEM sorted? How are you finding it?
I'm not sure how much of a difference it makes as the turbo heats the air considerably and the intercooler does a very good job of cooling and then there's the water injection

It's not the temperature effect of of the hot air, it's that it's lower density.
Once you're moving, the exchange of air under the bonnet, I think, wuold mean that if your car did breath in hot air, it wouldn't do it for long. Plus you have a air feed - it won't ALL be hot air.

on the way back from Deustch Connection show (won best Seat and Nick came second, WELL DONE MATE!) today the car felt so strong.... so i nipped in the house and grabbed the laptop then headed off to the hangers for a blast up their straight...
i cant make up my mind if the figures are good or not. it feels rapid for a hot day. but i have got loads of sound equpment in the boot, not to mention dynamat!
outside temp 22.5 running B9 T6
temps are high!

both well deserved! So much for not winning now the CH's have gone eh?
Absolutely awesome result to you both and well deserved.
That car is shifting some air as proved in the turbo pressure flowed at the red line, never have i seen a stock k04 flowing those figures unless the actuator has been well cranked.
The direct feed from the grill is where i'll be feeding my dynatwist from.
are you running a FMIC.

Thanks Carl (spelling?)
Ive read lots about people playing with their actuator but ive always left mine well alone.... its so quick at the minute i keep wondering why im going BT.... i then remember about the cam chain and know im saving money by doing it now. if i get the quotes back soon theres a possibility it can be done before the national meet.
i modified Nicks on Saturday but hes trying to get over boost leaks before he does any logs. im really hoping that someone else gets the same results. it'll be interesting to see if you get the same results with feeding it from the grill.
im running a Forge FMIC... its normally very good at coping with the heat.

Well done chaps, as said well deserved!
On another note, going back to the modified heat shield absorbing heat due to being metal... I have the carbon bmc... you can see where I'm going with this... is it worth modifying this in a similar way?? Not sure if I could plant a different filter in there easily though??

This is what I'm thinking too.
Even two feeds to this, one to the side and one in the conventional method
Looked into this with my BMC chaps and not a lot you can do other with the standard filter other than 2 feeds although could fit another filter as Riko says but would think it would be fairly small.... If you pull the filter apart the front section that the feed attachs to is directly moulded the the filter so any holes drilled would be bypassing the filter totally and sucking up all manner of crap.
