Quite induction
pudding:
BMC do a couple of compact solutions, like the OTA and DIA. Both come with 85mm OD intakes, so only a very mild drop down from the 90mm pipe.
In was thinking of putting one of these in front of the battery to replace the cone.
Sucking in hot air from the engine bay is overplayed in the aftermarket. It's not that big of a deal with a turbo engine since the turbo itself will heat the air to around 100 degrees C at full boost anyway.
colesey:
Is there a way of modding the standard airbox to improve flow whilst keeping things quiet?
pudding:
I'll have a look into that but I doubt it. VW already did a great job of squashing a traditional plastic airbox into a pancake to sit on top of the engine. The fact ED30s can make ~330hp with nothing more than a panel filter is a testament to their engineering.
If one is prepared to relocate the battery to the boot then all manner of quiet options are available to us, such as the beastly R32 airbox. It's a huge bucket of cold air for the turbo to drink from. Perhaps a little project to investigate in the summer. There must be a reasonable size battery we can lay flat in the spare wheel well......otherwise an R32 boot floor is required......which is a bit extreme for the sake of an intake :smiley:

Regal seem to have taken the loofah on a stick concept one step further, with a flex coupling :surprised: Finally. You never see that in any intake kits!

Not one of them have laminar air flow corrector gauzes upstream of the MAF though. I love how aftermarket parts people just completely omit key functions and then try to convince us they are not necessary when questioned about it. And then 6 months later when the mounting lug has snapped off the Revo intake pipe due to the lack of a flex coupling.......silence.

It's an intake from Integrated Engineering, not from Regal. I didn't know its existence. :happy2:
I'd like to know if the MAF scaling is really correct. The VWR intake is 4,7% off (which is still acceptable but not exactly the same as stock). A good tuner can correct the difference scaling, of course.
