Though TFTs are an interesting move, those are the ones that relocate the filters to the left side of the motor, right?

Correct -- I'm aiming for 450-500 rwhp right now and I don't think I'll need the inlets for that. I doubt my AT can handle much more.. Once I'm ready to think about transmission upgrades then I'll think about adding TFT inlets and cranking it up higher

Don't underestimate how much flow affects everything, even at the same power levels.

But good luck, 450-500 shouldn't be an issue with those turbos. Can't wait to see the final result. Also let me know how the car fairs at autox now!

Hmm, are you saying turbos will need to work less hard to make the same power? Or that there may be a better torque curve at the same power levels with the inlets?

FWIW, in my last event before turbo failure, I was ~1 sec off the fastest pace in my class (BMWCCA, not SCCA) and I could have definitely shaved off at least that much by not making as many mistakes. This car was certainly a great contender in AA. I'll let you know how I fair in AAA next year (doubt the car will be ready for the last events of this season )

Exactly that.

Inlets make the boost level more consistent throughout the rpm range and improve transient response of the turbos. Also, some people have nearly eliminated the torque drop between 6K and 6800 with inlets installed.

I'm consistently a second off of F80s (who set fast pace in my class) at my local autox with a 245 square. Can't imagine what it'll feel like with 275 and proper tires.

Basically i'm saying that i'm very jealous of you!

[dbronnik]

New H&R front sway bar, stett charge pipe, fuel injectors, and o2 sensors are all installed.

My stock turbos are behaving again and logs look clean so I'll be able to make the last autocross event of the season tomorrow!

I might go with the VTT inlets after-all; it is going to be too much work to reinstall the TFT* inlets every 2 years for smog

Ohh right. Cali. I forgot how hard it was to mod out there.

1M front looks great on the 'vert.
I like your setup a lot!
Do you pull the JB4 off every 2 years, too?

Thanks!

No smog tech is going to open your ECU box

But wait, no upgrade to your FMIC?

And what tires were your running in that track pic?

I'm shocked you've got all those mods and not an intercooler that would of been one of the first on my list! It sure was mine!

Extra 10-15 lbs in front of my front wheels hasn't been super appealing to me given I use this car mostly for BMWCCA autocross events.

how did you install m3 dct paddles?
I have 2013 135is and want to know how you did that.

I made a wiring harness for it to work with my steering wheel/AT (there's a long DIY post on one of these forums on how to do it..). You could just buy the harness from BMS instead (http://www.burgertuning.com/paddleshift.html). I'm not 100% sure if it works with DCT though (I have an AT).

Aerocatch install on revozport carbon fiber hood

[BrokenVert]

Looks good! I love that hood

[houtan]

awesome build.

are you running the red ground control coilovers that are currently on their website that come with the m3 lower camber arm? If so, how do you like the setup? Any issues?

Thanks! Yes, I'm running that kit (well mine is different colors, but its the same kit) -- absolutely no issues and I love the setup!

[TWMPerformance]

Hood looks badass!

Can you post some pics from the side and rear to show the width change from front to rear? Thankyou

Like this? It's pretty much squared up

[BrokenVert]

So did you decide on inlets for those bad boys?
