Modified 335D

I've been traveling and working a lot but there were some PMs and questions I missed regarding the modifications on my 335D. I will head to PB Raceway this evening to test it. Here is what I have so far:

2011 BMW 335D Montego Blue
- Premium Package
- Sports Package
- Renntech Tune (358 HP / 496 TQ)
- Quaife Limited Slip Differential
- Wheels: Dynan HRE D750-0020-P43S-BLK (22 lbs front, 22.6 lbs rear)
- Tires: Michelin Pilot Super Sport 255/30-19 front (22.7 lbs), 265/30-19 rear (24.9 lbs)
- Beltronics STiR Plus (Radar Detector)
- Laser Interceptor LI Quad (Laser Jammer)
- Zaon Flight Systems PCAS (Aircraft Detector)
- 3M Crystalline Automotive Window Film

Here is what I begin next week:
- Performance downpipe
- Larger intercooler
- Titanium performance exhaust
- Upgraded brakes
- More Renntech fine tuning

I willl post some photos if I can figure out how to post from Skydrive.

Here is another photo of my car. I'm not sure how to make it larger.

255's in the front? And you don't have problems with rub, even with the 30's? Those are pretty damn wide for that front wheel well. Only thing you have ahead of me is the Quaife. You're close otherwise. Seems FL is the place to be to mod the d, though...lol.

I don't have any rub though I probably could have gone with thinner tires in the front. I ran the track today but my launch technique is poor so the car is clearly capable of more. Also, I didn't start in M2 or use manual shifting. I just turned off traction, put in DS, and went.

13.639 @ 105.28

Nice ride, but you really need to blackout those lower front grills.

And the ugly orange reflectors too.

I want info/pics on the performance downpipe and intercooler.

Nice ride!

I actually blacked out the front grills but didn't like the job I did so reverted back to the grey ones. I may do it again better because it makes it look so much nicer.

I'll post more about all of the mods including the intercooler, exhaust and downpipes in a couple of weeks after the job is done.

I like that I'm consistently above 105 MPH on my few 1/4 runs but my launch technique sucks. I believe the car now is capable of around 13.2 in good hands but I am speculating. My ultimate goal is 12.9 but that may not be possible with this car.

It is. Need the right tires, and a proper surface. The car can run 12's all day. The hardest part is controlling the wheel spin at launch, and it takes a bit of practice. Your 60' is pretty good, considering. I'm one of a few people who have their cars to a ~4.5 0-60, and with meth, FMIC, and exhaust work coming, I'm interested to see how much improvement I can make, personally.

Good stuff!

What my car has been through...lol

with a 1.9 60' I ran a 13.0 @ 105. bit more power this car is in the 12s

Which is what I'm saying. I'm pushing 365 HP/589 lb/ft to the wheels. It's there.

Good to hear. With the new downpipe, cat delete, titanium exhaust, and larger intercooler I should be able to get there (<13.0). I just need a little driver training as well. Also, I think the temperature and humidity last night didn't help. I'm not sure how much difference it makes but as a pilot of a piston plane, there is a marked difference (cold dry days are good).

Is that with a dyno? Crazy amount of torque there dude! Can the D gear box handle that? You worried at all?

Yup, on the dyno, but due to some data loss, I can't find the files to post them up...sucks. I'm not worried, no...transmission has proven fairly stable, and I've been running the current tune for over a year without issue (aside from increased soot creation).

Good stuff man. You guys need to get YouTube videos up of your rides in action!

Is Renntech doing all of that?

with what mods are you making that power?

With that much power at the wheels, I would think the trap would be much higher, even if they were crank numbers.
I trapped 103 with just a JBD and heavier wheels.
What kind of dyno were the numbers made on?

My car looks very similar to yours, mine is also Montego. I just changed the lower bars to black and left the surround gray, made quite a difference.

As of right now, solely a tune (DTUK installed).

Technicar in West Palm Beach working with Renntech. I'm headed to the track again next Friday since they're doing a BMW only day.

Would be fun to run our cars against each other post mods but you're too far away. Also, I won't be doing meth. I wonder if my wide front tires slow it down a bit. I took dynan's advice when buying the rims and they look cool but probably overkill at 255 in the front (this is their recommended M3 configuration probably track not drag optimized). The LSD makes a huge difference avoiding fishtailing on a poor launch.

Hey I was supposed to be on that I sent photos to Hatmut,I guess they like the trees behind the car ,LOL, BTW dis Lenny configure ur ecu he did mines

I work with Robert at Technicar who probably works with Lenny. I used Technicar originally to install all my speed "protection" equipment Now I use them for everything and they send it out for this type of stuff. The coolest unique install I have is the quaiff LSD. I love love love how this car drives.

This is the only thing holding me back from a tune (and warranty). Do you think the additional soot will have a long term impact on the DPF? I'd hate to see a clogged filter which requires an off the vehicle cleaning and refurbishing, as I'm sure that won't be cheap.

I think one of the members participating in this thread has had his DPF replaced.

One advantage a remap has over the boxes is the ability to increase boost and better utilize the extra fuel, which will reduce the particulate matter (PM) sent to the DPF. As an example see data starting at post #49 here: http://www.bimmerfest.com/forums/sho...=598240&page=2

Also, the use of water injection significantly reduces PM emissions, which is one of the many advantages. See this study for example:

http://pubs.awma.org/gsearch/journal.../32_07_725.pdf

And the 335d responds very favorably to water/methanol injection as seen here on post #59
