335i rolling start beast

NRudy · 03-17-2016, 07:29 AM

Ive owned my 335i coming up to a year.

One thing ive noticed that not much in a similar power bracket can pull on it.

Ive had a Golf R (306hp) E92 M3 (420hp) 645ci (325hp)

There has been others but none of the above managed to pull on my stock 335. Most of the time i was reacting to them flooring it so i was slightly off in putting the power down but i either pulled on them or stayed level.

Ive read alot about the 335i being underrated in the power department but when comparing to cars of higher power it seems like it performs strong.

Off the line is always a struggle to get the 255s to hook up but the rolling performance definitely shines.

One things ive been told is the 335i was underrated to maintain the dominance of the E46 M3 as BMW bosses didnt want a none M car to out perform the previous generation ultimate driving machine, how true that is though is another matter.

Anyone else noticed higher than predicted performance?

It's basically because thanks to the small twin turbos, the spool up is quick and peak torque is all the way down at 1300 rpm. As HP is a factor of torque * RPM this means that for many revs the 335i is producing more power than the other cars you mention. Dynos (and car power ratings) only indicate peak torque and peak power at a specific RPM.

Overlay the dyno results on top of each other and you'll find the M3 might only be producing similar or more power between 6000 - 8000 rpm

The 335i has more usable power.

N54 equipped 135i (stock and tuned)

E9x M3 (stock with upgraded exhaust)

I've been against an E92 M3 and a 335i rolling starts and pulled away from both. Would be really interested to see how the D fares against a modded 335i on a rolling start. As you say its tricky from a standing start to get all the power down.

Will maddox · 03-18-2016, 02:10 PM

I feel like my 335 is inconsistent in how it pulls maybe that's the stock fmic, also I could do with pulling the vanos solenoids to clean them up.

pmmcbl · 03-18-2016, 02:51 PM

Do you have a n54 or n55? I thing the numbers will look different on them.

KiwiRD · 03-20-2016, 10:40 PM

I have a stock N54-powered 335i M sport E90 in manual. I must say that if you're in third gear at 3,000 rpm on the open road and boot it to overtake or whatever, the amount of shove is pretty impressive. I can only imagine how much better it would be if it were 200kg lighter! I have the MHD Stage 1 93 tune on my tablet, but I haven't used it yet. In many ways, the standard power level is more than adequate for 95% of situations.

Well next time u are down Santa Pod way maybe we can give it a go

AWSAWS · 03-21-2016, 10:22 AM

I just have the worst starts from a dig. Here are my excuses

I think it comes down to having lots of Torque thanks to the mods
The shorter ratios of DCT (7 gears vs 6)
The fact the DCT manipulates the clutches under 2000 rpm in 1st and 2nd gear. (It's designed to feather in for road use so means it can be tough to start off with enough aggression and then not over cook it one it fully bites after 2000 rpm)
Can't brake boost like a sterptronic
Launch control is useless. Fixed at 5000 rpm.

I went against an E92 M3 the other day. I passed him at an average speed on the quiet private-motorway and he didn't like it - next thing decided to undertake and cut in front of me.

He nailed it so I thought why not give it a go. I have to be honest and say that there was not much in it at all. he was not able to pull too far away from me. repeated runs from -80 to -145ish. He simply wasn't getting away or gaining much ground.

I am certain that my MHD 98 remap to stage 1 / 1+ would have been more than enough to see it away easily.

I was quite shocked actually, thought it would have killed me. Can't imagine he felt good about it at all.

I have also left many far more powerful cars behind / not able to get away in the stock N54, I think it really is a special motor.

On another note: how does the old 135i fare up against the 335i? are they much quicker? don't see many of them cover this way.

Not you lol. Considering you're reaching nearly 120mph there's no point, you'd have me easily. But if we're both down at Santa Pod it would be fun to run against each other just for the hell of it!

Maybe once i've fitted meth it may be a bit closer...

I was exactly the same when it came to the M3. I actually felt sorry for him, i know he saw my 335i badge and said to his passenger watch me leave him, then when he looked along side and i was there looking back it hurt his soul.

The 645i was a shocker too considering it has another 30hp on the listed stock N54 he wasnt happy to see me pulling on him even though he pressed first.

N54 is an amazing motor and it always puts a smile on my face when i see someone who thinks they will destroy me get the shock of their lives. A SL55 AMG and a A45 both said "i go against bmws all the time but yours is fast"

Im like "yes it is" if i wasnt so scared of the maintenance issues id happily be running jb4 with bolt ons but voiding my BMW warranty isnt an option right now.

Get the MHD flash then, if you have issues it take about 3 mins to flash back to stock.

imy · 03-23-2016, 08:31 AM

I see your running stock? Get a JB4 on that and see what youl keep with

Im now in a financial position where I can an E60 M5 comfortably and properly but man I love my 335i too much. Ive had 9months and I absolutely adore it.

Edit: JB4 and warranty pretty easy to work around, either turn it off or just remove it. Gets easier the more times you do it and is totally worth while! It transforms the drive and you can change all types of set ups from it.

I don't have any experience of MHD but sounds like a great alternative also.

alex-qts · 03-23-2016, 09:29 AM

Yes MHD is fantastic. Flash back to stock is very easy, just make sure you take a back-up of the stock ECU file first.

MHD restores a 'stock file' back no problem, but I had coding errors due to the ZB numbers not matching IIRC. Best to restore your exact backup IMO, especially if you are planning a visit to the dealer.

V6 maps for MHD are going to be publicly released soon, meant to be a big improvement.
