Nice, thanks for the update. I've seen your other issues, just wasn't sure if you gave up on the CAI for now. I've been looking at my air box for the last hour or two. I have some ideas too, but not sure if I want to commit. The opening into the air box is twice the size of the opening from the air box to the turbo. Definitely a problem...I don't see any room for air filters outside the radiator bracket either...

Yeah you can't do it unless you have a face lift on your car or BS kit, But I'm getting ready to order the BS kit and have it installed so I will do when the kit is being put on

So you are no longer putting the filters on the other side of the radiator? I have been thinking on my intake setup, I have the scorpion set up which looks great but my off the line acceleration isn't great because of how much heat the intakes are sucking in. I was thinking that things would be tight in front of the grille, but still possible with the right piping and filters I would think. I wish I lived in a bigger city with some options to work on my car, the shops here act like my car works off a nuclear reactor

I have been having the same war with myself. I just put my exhaust back on in an effort to focus on the intake issue. I am also not crazy about having the filters in the hot engine bay. I don't see a ton of room behind the grill either, but need to investigate some more. Intake is a bigger problem than the exhaust for me (I have no mufflers, only cats).

Not sure what that means? Stock airbox with new piping, or no airbox? Curious what you're going to dyno for?

I am now starting my R&D on this stupid air box issue. I think there is more power to be gleaned from improving intake than exhaust. It's sort of surprising how little information there is out there regarding the intake on these cars...other than the $5000+ solutions...

I thought thericker was able to get filters out front of the rad support, before he did his Misha conversion. Not 100% on that though...

I read one of his old post saying the oval head lights made it impossible but IDK if he managed to do it or not. I do know that doing it on a face lift model gives more room as the headlight design doesn't take as much room

I'm not sure what nose is even on my car. It could be stock ,but not really sure..I suspect it's not. But nonetheless, nothing will fit up front for me, unless I can find some filters that are LOOONG and narrow...
I guess I could relocate my horns and remove some brackets, etc...

03-08 is 1st gen R230, 09-12 is 2nd gen R230. The headlights on the 2nd gen gives more room for piping to go through the front

Here's pic on my 3 inch intake set up, (silicone tubing from turbo mid section then aluminium piping to air filter) been waiting for a dyno time but theres a rebuilt GT500 and a 95 OBDI M3 that I'm waiting to leave the shop (If anyone has been to the shop they know these cars have been there forever, I could say why but that would be too mean to the owners of the cars)
OEM engine cover can fit over this as well
Here's pics of the OEM airbox
As you can see in these pics, the pipe from the air filter to the turbo is very narrow

Interested in your results for sure. I'm of the belief that the increase in CFM will overcome the initial warmer temp of the charge air.

I was going to say that I think there is a shield behind the grill to keep incoming raing to a minimum and with that removed you should have a fairly cool air charge coming in assuming you are moving

I don't have a V12TT but I have done testing with cone filters in the engine bay and the hot air from the engine dramatically increases IAT's which kills power. Remember MB cars pull timing as IAT's increase. The higher your starting IAT, the higher your max IAT will be on a pull. I would try to get as much cold air as possible and at a minimum shield off the engine bay heat with a barrier like sheet metal. You won't see this on the dyno with the hood open. You probably wouldn't even see the effect to its full extent on the dyno with the hood closed unless you let it sit with the hood closed for a while and then did a pull.

Initial temp of air ingestion will be higher, no doubt, when sitting still. Say, at the drag strip starting line. But, the filters sit right behind the line of demarcation, where the snorkel ingress is. When the car is in motion, and not ingesting static air, the charge air might be moving at a rate quick enough to render under hood heat irrelevant. Well, not irrelevant, but only subject to same amount of soak you'd see from a stock setup. Add to that, the gain in CFM might also overcome the possibility of power loss from spark retardation due to increased IAT. The main issue I see is the material used. Metal gets hot, real hot. So if the tubes used get superheated, I can see IAT, in stop and go, traffic get stratospheric. Double whammy, right? Static under hood air ingestion, plus superheated plumbing...
I dunno. Discuss...

Sorry been busy I'm leaving to the UK and the Gulf next week until May 1st for a Business Trip and my Sister's Wedding but I'm gonna try getting a run in. But I'm not to worried about it since the body kit is getting ready to be put on soon and I'm gonna do that other intake set up. Trying to have everything ready before timmayfest

Hey Ahmad, what's your thoughts on this...
