Hello guys,

during my vacation in Germany I had my 335iA (E91) engine "rebuilt" by a company close to Stuttgart.

They have installed new software on the ECU, bigger intercooler, oil cooler and sport CATs. The modifications took one long day to carry out.

After the rebuild I have driven a lot on the German autobahns (no speed regulations) and have testet the car against some other quick cars. Need to be said that my car was packed for vacation, and that my familiy was present all the time (wife, two children). Thus I did not test the top speed which by an other customer is GPS measured to be 312 km/h.

First; the exhaust sound is much more present. I really enjoy it and it brings much more sound when accelerating. The car now really sounds like it should, having so much power.

Upon returning from the garage I initially reacted to a feeling of slightly more turbo lag, but from the second day on I haven`t thought more about that and it doesn`t bother me. Now, after 4500 kms I really can`t say if there is any more turbo lag than before.

Of course, the car is quick. Before the tuning I tested it against an Audi S4, which it was equally as quick as. After the tune I met a new S4 (V8, 344 hp) on the autobahn and it - of course - tried to outrun me. It was a pleasure to be behind him and almost pushing him on the bumper all the way past 220 km/h until he gave up and let me pass. Remember, he was alone in the S4, I had my entire family present.

Later the same day I was challenged on the autobahn by a MB CLK 63 AMG. This car has a 481 bhp V8 and 600 Nm torque. He also tried to outrun me but it was impossible for him. I hung in there, losing maximum 10 meters to him up to 260 km/h, when he opted for the right lane and slowed down. This guy also was alone in his car, and I still had a fully packed car.

Of course, the AMG car was a tougher match than the S4 and I could probably not outrun that car. During the acceleration he cot a couple of car lengths to my car but then again he had the advantage of being in front, being able to start the "competition" and gain a little before I responded. But it was a fantastic experience for me which I will never forget.

The company that has developed the tune, Noelle motors, and the garage that performed the tune, says the rebuilt 335s are quicker than the new M3 with a claimed 0-100 time of 4,6 - 4,8 seconds. This is because the torque is higher and kicks in earlier.

After the rebuild the car seems to have the same gas mileage, but I have not measured that exactly. The cars gas mileage meter has at least not changed after the tune.

By the way, at the day the car was tuned, it accidentily ran on 95 octane fuel. After the tune the car was dynoed to "only" 353 hp/503 Nm. After a week (and 1500 kilometers) I returned to have it measured again, now running on 100 octane fuel. This time the car dynoed 50 hp and 25 Nm more. Lesson is; buy the right fuel if you want to have maximum output.

And there has been no warning lights or other complications on the first 4500 kilometers.

Nice review Reeser. I know Karl-Otto Noelle quite well, and the products his company makes is very good. Certainly his ECU remap is fantastic, that coming especially from his background in building the renowned Alpina B10 Bi-Turbo engine in the old E34.

The cost is a little high, but the quality is there. The only problem though is that if BMW update the ECU software on your car, then the remap will be overwritten and a visit back to Noelle or one of their dealers will be required. That's the ONLY reason why I haven't gone to Noelle for a remap, as the drive back over to Germany from the UK everytime my car gets updated (which recently has been a lot due to injectors and dogdy FALSA data etc) will be a ball ache...

Glad you're enjoying it though! Out of curiosity, what sport cats did they use? And was it from the downpipes back (so replacing the dp cats as well) or just the middle section and back box? And which intercooler and oil cooler did you upgrade to?? They didn't come from Noelle as well did they??? Am interested in those parts (otherwise I'll get a Spearco sent over from the States)

Thank you for your remapping tips. The garage, EVOtech, also made me aware of this fact and advised me to tell my local dealer not to do any software updates. Which I will do and just hope for the best.

I did not see the mechanics when they changed parts, so I do not know how much exhaust parts they have actually replaced. But after afew days I visited a garage and could view the car "downunder". It looked like the changes is in front of the system, but that`s just my unqualifies guess. So except from the much braver sound of the car, you cannot experience any outside changes.

To all the other questions you have; my answer is; don`t know. I`m sorry

Noelle uses RPI intercooler.

[longodj]

can you post up a dyno sheet?

[I335]

Sounds great and lots of fun! Question - I'm assuming that you did not actually have the engine "rebuilt" in a day, but that you just did the tune with the parts you mentioned, correct? Is something like this typically called a "rebuild" in Norway? When I hear rebuild, I think of "take the whole engine apart, balance and blueprint, and put it back together - perhaps with higher performance parts. Anyhow - congrats - sounds like you have a beast there!

[sflgator]

I believe Eugen has the Noelle ECU Flash for his E93 335i as well.

[longodj]

EDIT: nvm..

[e.n335]

I have the ECU-Flash only. It puts down 373 chp. I am curious how much it will put down with the Spearco FMIC now.

The 401 chp version consists of a bigger oil-cooler, DP's with metallic cats and the ECU-flash. The DP's I've seen were OEM with metallic cats inside, very nice welds. AFAIK no FMIC.

You`re right. It`s no more rebuild than what you said. Also, in Norway, a rebuild is more than this. But it`s more than just a chiptune, so you might have a more appropriate word for me?

Thanx,

I will try to to that tomorrow. Have no scanner here.

[stressdoc]

Awesome car! Interesting that you have a beast for the family car, and a fuel-sipper coupe!

[remmib]

Great write up, and I hope one day to see this sporty wagon live someday.

[WilyB]

From NOELLE's web site:

Karl-Otto Noelle is currently developing a 335i conversion offering 400 Bhp. This kit will include new pistons, optimised intercooling, sports catalytic converters and a 4 pipe stainless steel exhaust system. The maximum speed will exceed over 187 Mhp/300 Kph, and will include new suspension and braking components.

If those pistons are engine pistons, there might be some serious disassembly involved.

[e.n335]

^ Noelle does'nt use different pistons. He planned to do so, but he found that the OEM pistons do a good job. Have a look at his homepage.

Very nice car and excellent review.
How much does the E91 weigh?
And reeser how much do you think your extra weight was about?

The 335i E91 with automatic gearbox weighs some 1630 kg, incl 2/3 tank of gas. Mine is well equipped, has 20`` wheels, and probably has a weight above that. Excluding the driver (me), the additional weight of the car must have been around 200 kg (my kids are just one and three).

Here it is. It is in german but I`ll translate some of it:

Motorleistung = max engine output
PS = horsepowe
Drehmoment = torque
Lufttemperatur = air temperature
Radleistung = output out on the wheels

Because the automatic transmission upshifts they had to try four times before they succeded in getting a fair measurement. The garage said that these runs caused the temperature (inside or outside the engine, I don`t know) to incease so much that hp dropped by some 8-10 hp because of that. They said that the engine therefore is around 405 hp. I do not know if this is a probable explanation or not, but some of you guys might tell me?

Thanx

Hi Reeser.
I just came back from one of the M5board event.
This time the focus was the on the new M3 E93 and its competitors.

I did pull 2+ car lengths on the new C63 AMG from 50-240km/h
So with you alone in the car, the C63 will be no problem from a roll.

When comparing to the new M3 I pulled even more CL...
But when we did some measurements with an advance equipment from 0-200km/h
I lost to the superb launch control of the M3 by a few tenths of a second.
So I would not challenge either cars from a dig.

Hello Heartware,

that sounds amazing, is your car modified or stock...?

[Heartware]

...I am stock ^_^

Here is my stock 335i

Seriously, I got the Procede V3 with cat back exhaust. Still waiting for the Down pipes. I think with the downpipes the car will really open up from 4500rpm to 6500rpm.

But then again, I am running 19X 10.5 inch wheels at the back.
That’s no good for high-speed runs.

I did some runs against a Noelle M3E92 with 480+hp
and I was leading all the way to 200km/h, then it started to pull on me and jumped ahead until we reached 250km/h. I wonder if it was the aerodynamics of the car or was it the lack of downpipes?

I'll send you a PM as soon as I get more info about the coming event.


Here is an example of the races:
