335i - 380bhp/420lb ft !
Discussion
Was reading BMW Car magazine last night, article about re-mapping.
Apparently the 335i and more alarmingly 135i (presumably) can be re-mapped to provide 380bhp and 420lb ft !!!
That's unbelievable performance from a 3.5L straight six.
Even makes my CSi look a bit limp with 380bhp and 410lb ft
How would the gearbox and clutch cope with all of that based on how strong the CSi gearbox is reputed to be to cope with all that torque?
ps., I know the 335d can be re-mapped to even higher levels but they're autos so don't count

I run a Jucie Box Stage III in mine (335i touring manual) and I reckon I'm getting about 360/370 bhp at the flywheel (its approx. 340 bhp and 350 ft-lbs @ the wheels) - totally transformed the car. Same driveability but loads more power. Done about 10.000kms many of them fast Autobahn kilometers. Only bugger is that it's still limited to 250 kph.Apparently the 335i and more alarmingly 135i (presumably) can be re-mapped to provide 380bhp and 420lb ft !!!

Things to consider;
Honda had 100+bhp/litre in 1978 Normally Aspirated,
Most all BMW "M" cars have made 100+bhp/litre since 1991
Chipped "street" RS Turbo made 130bhp/litre in 1986
Poor old 850CSi is a Single overhead cam, 2v per cylinder engine from the 70's, but they will do 200,000m easy if looked after.
Lets see a 380bhp 335i at 200,000m, or even 50,000m. Turbos and engines on order by Direct Debit?
Respectable figures for 2008 I would say are 110bhp/litre NA, 150bhp/litre FI. Both for a production vehicle.
Just to compare, a good RS500 Cosworth would make 550-600bhp/2 litres in 1987.
Terry Kizers Kawasaki made 737bhp from 1.5 litres in 2000 on a STREET BIKE! Gulp.
BMW F1 engine made 1000bhp/litre in qualifying trim in the 80's
In conclusion, 380bhp is not really impressive for the chipped 335i twin turbo motor in road trim ( this level available since 1986) but will make for a very rapid, small car....that is the point, a SMALL CAR.

I have never seen a compressor flow map, or details of the strength of this motor, so find it difficult to understand how much stretch is involved to achieve this power level compared to standardThe article is referring to the remapping of the 335i's done by Evolve.
Next month's edition of BMW Car Magazine has a feature on the remapped 335i as part of an article on the comparison between remapped and standard models, from a performance perspective. Should make interesting reading.

The 335d can't be mapped up the 380bhp ... yet.Apparently the 335i and more alarmingly 135i (presumably) can be re-mapped to provide 380bhp and 420lb ft !!!

But 380bhp should make for a reasonable turn of pace. It'd be awesome in a 135i, but then is the 135 much lighter than a 335? They're still both pretty lardy ....
I currently run a manual 335i with an SSTYT chip. It really is amazing. It adds around 40bhp at the wheels (so the company says anyway) and having had it off for a week while the car was serviced recently i can testify that the SSTT is amazing, it really makes the standard car feel like a snail. I am getting very tempted by a plug and play JB3 for even more power. I work in USA so luckily have the access to some very cheap products!
- my std 130i has 88.3 bhp per litre and would hope there's a little more to come anonymous said:

Fat in comparison to what?135i = 1560
350Z = 1534
R32 = 1515
I would imagine that the MB C Class Coupe is heavier still as is the Brera. It's an unfortunate sign of the times
Others...
335i = 1600
335d = 1655
M3 = 1655
S5 = 1630
I do concede that Audi have done a great job with the S3 1450, but the 135 has noticeably more power
Remember the that the 1 series coupe is not far off the same size as the E92. The space in the rear is about the same, but the boot is bigger in the E92.
The weight certainly does not affect the performance, even as stock it's mighty fast for a 1 series, only M cars are faster in the BMW range.
Not sure how manufacturers are supposed to keep the weight down with all the EU regulations? I can only see new cars getting heavier, although I do think that weight reduction is a key driver for making cars more efficient over the next decade.
