Jeez that's two of my car lol..it looks incredible. I'm gonna show my smog guy.

 

This is a great setup, I absolutely hate the stock config going all around the motor.
I'm sure that's part of the reason throttle response on and off boost is so lethargic on these cars.
what size intercoolers are those and whats available?

 

^ fully agree..and the look alone of all that plastic stuff yanked out seems worth the price of admission to say nothing of the gains!... hell, i cut open my stocker air box! left side lol

 

I make it on the 4.5s only... and I use all the space available... notice I have more bars across then most...

 

Not sure I follow. Dump the MAF, run normal BOV like these or a big one up by the Y-pipe, intakes over the ICs. Nothing different except I'd prefer smaller intercoolers is all.

The trick, so to speak, is engine management to dump the MAF and all of it's associated tubing so the turbos can breathe. There are few tuning the stock ECU and I'm not sure about a standalone which is why I asked what was going to be used with this? I have to pass plug-in emissions every few years so that's a concern...

Stock setup has an idiotic amount of piping, some of it pretty well crushed. The passenger sides runs all the way around the front of the engine up to the airbox along with the driver's side all so the stock ECU can breathe through the single MAF. If you slap a vac gauge on that piping and measure pressure drop you'll see that you're turbos are breathing through the equivalent of a cocktail straw! Dump that for something like this and it's like a giant McD's straw! Faster throttle response, faster spool, higher power. There's kits to enlarge that tubing but given a choice I'd prefer to eliminate it altogether.

 

This set up is nothing new. Been doing this for 10 years. It also can run on a blow thru Maf as well. I like the DVs closer the the turbos. I have this set up on my own car and it does run mid 9s and traps 155 mph. No meth for cooling either.
Smaller ics require more work to get the holes all around it covered. If not this approach doesn't work as well. The whole point is to trap the air into the ics not go around it. Mind you - the top plastic piece is gone at this point.

Oh I know you've done it for awhile! But to make it all work proper fuel management is required. I'd be willing to go blow-thru so long as the metering remained accurate. Speed density has the downside of needing a retune when VE is changed by parts upgrades, MAF is a little more forgiving.

I hadn't realized you were removing the entire top duct Marksi, I need to pull my car apart and poke around to see what I can do. I agree that trapping the air above the IC is critical both for cooling but for air intake as well. Even if the intake isn't subjected to pressure it'll be WAY more efficient than the existing multiple feet of current intake piping!

I'm just not sure I want to go that large for intercoolers, partially due to cost :-O Still researching and pondering although I do know someone running MAFless who needs an IC an intake setup I'll point at this :-)

 

mark do you have mafless tunes for k16's or k24's?

 

I've been running this setup for years now. I'm very happy with it. It drives like stock and I've had zero problems with it.

 

Very nice..
Hmm,,but I don't think I am in the Big Boy League ,,yet.. LOL..

 

...me either! Ha and I did show the pics to "my" smog guy and he said "don't bring it to me". Good thing I can only afford to go small and stay home. I can only wonder.

 

I still have my extended warranty until Nov.2015 so I like to keep it looking close to stock,, besides my car is dialed in to the tee anyways.
That warranty has paid for itself a few times over..

 

There are a couple guys in CA running this and I'm sure a lot more on similar set ups. As long as your exhaust passes emissions and inspection Im not sure what the issue would be. What's the difference between lets say my y pipe and a oem painted red y pipe.

 

none, and red pipes get fails these days. they have a "visual" now that is far more stringent than ever before e.g. cat delete even = fail. simply put, the gov't is our friend. i'm quite sure that many running great stuff that are diy'rs or have time/money on their hands simply take off their stuff, pass for a couple years, then go thru the process again. i just can't flip intakes/tunes. my car isn't yellow, but i am. for me, and perhaps some of us, it's one of those: "my car would do that if i wanted/needed it to" which sucks, but thankfully i'm driving around 15 mph corners

so that's not to say kali is no longer a market for aftermarket stuff, but the more stealthily practiced, the better. your y-pipes aren't red, but it's obviously not "stock" and clearly promises more fun that "someone" would like "us" to have. even exhausts are supposed to have a BAR number now

 

How do you pass emissions (obd2) with this setup? Do you mark those monitors ready? In Mass they can see you tuned a monitor to pass. Or am i missing something?
