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.
