    • The difference a DCT makes - BMS Tuned 2014 F10 M5 vs. two BMS tuned E92 335 N54's with upgraded twin turbos from a roll

      The camera car in these two videos is the Burger Tuning F10 M5. This car has a BMS JB4 piggyback and downpipes. Some impressive output at the wheels has been shown from this car on a Dynojet in the in the ~630 wheel horsepower range. That is a tall order to overcome for a 335i even for one equipped with upgraded twin turbos. The 335i just is giving up too much power and torque to the M5 along with quicker shifts to the DCT.

      And the DCT is the key. The first video shows an E92 335i that has a manual transmission and it gets crushed. The second video has a similarly modded E92 335is with the RB turbo upgrades but the difference is that it is the 335is model that has the DCT transmission.

      Look at the results and see what a difference a dual clutch makes for yourself.

        Amazing what a transmission type alone can do Click here to enlarge confirms the other video from pt f's 335is taking out the R8 and an M5 as well..

        Now imagine a DCT equipped N54 with a ST Click here to enlarge

        No surprise there. AFAIK the gearing of the DCT is shorter than the MT.

        Shorter gearing doesn't help the top end.

        The M5 isn't able to pull up top.

        DCT will be toast within a few pulls on ST

        Oh my ! I just about fell over in my seat when I saw what the 335is DCT did to that tuned M5, and to boot, it just kept pulling. They were both DCT cars. I made mention some time back my expereince driving the new M6 and M5, the DCT shift did not feel instant powerful like the N54/S65 DCT .

        Keep in mind the N54 DCT timing at post shift rarely drops in the negative and has an instant recovery.

        Not unless you keep the wheel torque within reasonable 500ft ib.

        Big st's normally don't have peaky torque like small turbos.

        Worse case scenario would to run to SSP for their upgraded clutch packs.

        Why? SSP doesn't have a real solution. Their stuff is junk. SSP is the worst choice anyone could make.

        I thought the first car is Serge's car which would make it auto not manual.

        Is it? I read something in the comments about manual.

        Pretty sure. His car is an RB turbo white e92 with carbon hood and deck lid. If it's his car it's an auto.

        No they wasted my time and my money without delivering anything. That's why.

        Prob has more to do with the tune , cars health, boost / fuel ran than the transmissions. You can't cloak the dct is the difference from two random runs.

        They have similar tunes and mods and it's a night and day difference. The DCT is clearly the difference.

        Too many variables...I ran my buddies IS and we have the same mods and it's a drivers race. He jumped out half a car or so and I'd real him back in...if I $#@!ed up a shift it was game over though.

        It also depends on how the first driver is shifting. If you flat foot it there probably isnt too much of a difference between the two. There's quite a few run ins that ive had where i know if i took my foot off the floor id have fallen back fast...especially noticeable in turbo applications
