Here's figures from a reputable mag, finally.

http://www.autocar.co.uk/RoadTest_Su...p?RT_ID=222899

5.4 to 60 (not even 62) and 12.8 to 100mph. Quick for a non-M series 3 but i'd take the 335d (3 litre diesel 284bhp) over the 335i any day.

Yes if you spent 3dollars and fifty cents it would make 400bhp blah blah blah.
I'm talking about stock.

For reference, Autocar tested;

C32 at 4.6 and 10.8
M3 at 4.8 and 11.5

People are all excited cuz it's TWIN TURBO CHARGED....



whoopie di F''n doo..



Those turbos are tiny and boost + high compression motor =
kaboom... I believe that has been done already.

I'm buying on in a few months .. and letting the C32 go.

here is are US tests.

http://www.caranddriver.com/roadtest...ecs-page4.html

http://www.caranddriver.com/shortroa...35i-sedan.html

Both coupe and Sedan are under 5 seconds..

and hit 100mph 12.1 coupe and 11.8 sedan.


The coupe with the options I want is 45k MSRP. Add a $1500 XEDE ecu and it will pust 315 to 320RWHP and 320 to 330 RWTQ....just with the chip.

Add a simple exhaust and you get 20hp and another 25 to 30lbs to the wheels.

That is Stage2 C32 power with choice manual or 6speed, better Weight Ratio, better brakes, and the handling is way better.

The sedan is about $3k cheaper and you have 4 doors.


I'm not buying for speed, but as my daily driver.

The E55 is my family cruiser and the car I would take on a long trip.

My C32 is a great car, but the 335i is just plain better. That is just my personal opinion.

My friend sold his '05 E46 M3 and bought a Lexus GX470. He has bimmer withdrawl and wants his old M3 back. He test drove the new 335i and said it's fast, but not the same as his old E46 M3.

I doubt that. Just because something adds 20hp to the crank doesn't mean you get that to the wheels. Plus an exhaust rarely adds that much power. Lastly, haven't you heard about the 335i over heating and shutting down because apparently BMW was too aggressive with the initial tuning of it and they are now reflashing the ecu so the car puts out less power.

as far as over heating... is not a common thing on every 335i. I have been at those boards for weeks now, and it is just not as you make it out to be.


as far as power...

I'm talking about a reliable tuner, very respected that is providing Dyno's with the different set ups. Vishnu know what they are doing..

The exhaust is very important if you want to come close to maximizing power output. Especially in the low to mid range where, tuned with the XEDE, it's worth an additional 40 to 50lb-ft of torque between 2000 and 4000rpm. The difference in tuning a car with a ton of exhaust backpressure and one without a ton of backpressure is huge. With the factory exhaust, I had to run less ignition advance, richer and be 1-2psi less boost in order to deter knock. With the free flow exhaust, the car responded much more positively to tuning. This isn't magic we're dealing with there. Pulling power out of ECU tuning alone isn't a free lunch. Do yourself (and your car) a favor and extract it from more than one place.

if you have time.. please read this thread before you continue to jump into any more conclusion about the 335.

This thread will answer all your questions.

Exhaust on NA cars rarely adds power. You are correct.

Exhaust on Turbo cars, is a must and adds lots of power with the correct tuning.

I'll give you an example.

http://www.vishnutuning.com/evo.htm

look at the power output over stock just from a ECU and better down pipes and exhaust. In Turbo cars, exhaust is a must.

and yes 20hp to the wheels....I never talk about crank number or marketing hp numbers. I'm talking only strickly base dyno runs vs modded dyno runs.

The BMW ECU flash has been done to cars in Canada, again you need to read the boards more often to know that. Those cars dynod at around 260hp to the wheels. Regardless if the 335i gets a new patch of software, tuners already broke the code and can get back the lost power and gain much more.

The BMW ECU flash is NOT a problem at all.

the 335i is a beast, its a lot of fun to drive. I would trade my slk55 for one if I didn't have the new m3 reserved for next summer. I have always been a benz owner and have loved every single one but bmw's are something different. Without modifications, a stock bmw feels so much more connected to the road.

No need to bash the 335i its a hot car.

I'm not trying to bash it. I've actually been considering getting one. I've just been scared off of it a little from all the negative press.

stratospere just got into the 335 buzz and has an exh for it.It gained 10 at the wheels.The dynos are floating around the net somewhere.

Shiv is up to 370ft lbs to the ground with a piggy back and exh on 91 oct now.He has a video of him going from 0-100 and is done at a hair under 10 seconds

I think think the car has about 400 ft lb and around 350-370whp tops on the stock compression and 93 oct.

Once you drop in a head gasket and lower the ratio you will see 400+ to the wheels.The car has it in it but will knock hard past 12psi with the high compression BMW is running stock

all thease gains we have so far is with only a 2 psi boost bump....I can't wait to see what 17 psi looks like

edit-please stop spreading rumors about BMW reflashing the cars to retune them.The update was to fix a cold start problem and changed nothing on the tune of the car.

and the people that started the overheating rumors where from an audi forum and someone called the track and asked what the story was and was told that 1 car over heated not all of them.

ps

bmw was not agressive at all in the tuning.They tappered boost to 5 psi after 5k and shiv made close to 100 ftlb of torqe just by messing with the timing and keeping the boost stock

I love you, man, finally somebody's has THE GUTS to speak his mind about the bloody 335i talking facts and not "ifs".
RESPECT

BMW hasn't put out turbocharged cars for a while and its exciting to BMW enthusiasts.

MB is going the way of turbocharging in the near future

Quoting your own article

BMW 3 Series Coupe 335i SE 2dr - Verdict 8 out of 10

BMW has done it again. Its first modern effort at a turbocharged petrol engine has it all: low-down punch, top-end zeal, deep-rooted character and decent economy. With this firepower, the 335i utterly nails the coupé criteria: stylish, practical, desirable and enjoyable. One of 2006's best new cars.

GDawgC220
The S600 has been turboed since 2003.

The 335i is siiiick. Almost E46 M3 power, C32 power. That's niiice.

I know the V12 is TT, but i'm saying more mainstream, not just one model.

Correct me if I am wrong but the last BMW turbo was the 745 of the late 70s..called the 745 b/c the turbos gave the car the power of a 4.5 liter V-8...

Funny but just a couple years ago they said they were going for large displacement engines b/c turbos and s/cs were complex and heavy and against their beliefs..

haha, yeah, BMW did say that about not going forced induction. But with gas prices and people looking at fuel economy, turbocharging is a way to get more power and better fuel economy rather than just going large displacement. They can achieve the same with a smaller displacement engine and turbos but providing the same fuel economy or better.

I know. I'm not trying to deceive anyone. That's why I posted the article. However, what you pulled out is pure opinion. 5.4 and 12.8 are pure fact.

My mistake.

I'm glad that they are going turbo. It's more fun that way (at least to me) to have more power low end.

its all good. I wasn't clear in my original post :p

it'd be interesting to see what MB comes up with for turbocharging.

The press has been very positive from what I have seen

OK, but what's your point?

Earlier, you said you'd rather get the diesel version. Fair enough. Other than that, I'm not really sure what your point is.

Don't recall anyone ever saying the 335i had the best 0-60 or qtr mile times.

Unless some records have been broken or some unbelievable time has been achieved by a new car relative to its (low) price, the "fuss" is generally not simply a result of 0-60 or qtr mile times. There's much more to a car than that.

I can see why you might want to initially compare against the C32 and M3, but remember that it is neither a replacement for the M3 nor a direct competitor to the C32.

dont forget about the turbo Deisels they have in Europe.BMW had no way to increase power staying NA and not use there M power Engines.There only other way would be to turbo charge a basic 3 series one.

BMW said they would never use FI in there M cars.

First things forst, i'm not bashing the 335i. Personally, i'm not keen on the styling and prefer the exclusivity of the C32/55, M3 and S4 over a regular 3 that will soon be everywhere.

My point in posting was fairly obvious. It was to show that the 335i is not the giant-killer many who frequent this board thought it was. People had said it would best the C32 and my car. I made it by using actual figures from a respected magazine. I linked the article to allay concerns of personal bias.
