Did you try loosening the tension on the filament? (Hobbed bolt). The filament should not be getting that distorted.
I don't run a Bowden, just assuming the filament tension is similar to a non-bowden extruder.

On my 3mm bowden E3D, I have to run the fan all the time, and when a print is ended, make sure that I retract - I do it manually when I abort a print.

Yeah that's really pretty fast not to say that you can't do it but probably something you don't want to do on every print. That would be something to use on hollow single wall thickness and still get a good print but as a rule I usually print with ABS which is a little slower and I stay between 50 and 80 mm a second it can go much faster but print quality suffers not from machine wobbles but how well the plastic welds to layer below. I've never seen a pro printer in person but I did see plenty of videos and I don't think they even print at 100 mm a second maybe 80 mm a second. If you can post a couple videos of it running we would all like to see it

What I saw from that last video seems like a lack of cooling the filament after being extruded.
You should definately get some sort of fan blowing at the PLA sideways.
Look at the Ultimaker 2 for example - it has two! fans more or less constantly blowing at the printed/extruded Plastic.
I saw one guy have just one of those two fans fail and the quiality went down a lot, so imagine how it would be without proper cooling.

Also 235° seems really really hot.

What layer-height are you printing at?

What are your values for Acceleration and Jerk?
#define DEFAULT_MAX_ACCELERATION {9000,9000,100,10000} // X, Y, Z, E maximum start speed for accelerated moves. E default values are good for skeinforge 40+, for older versions raise them a lot. #define DEFAULT_ACCELERATION 3000 // X, Y, Z and E max acceleration in mm/s^2 for printing moves #define DEFAULT_RETRACT_ACCELERATION 3000 // X, Y, Z and E max acceleration in mm/s^2 for retracts #define DEFAULT_XYJERK 20.0 // (mm/sec) #define DEFAULT_ZJERK 0.4 // (mm/sec) #define DEFAULT_EJERK 5.0 // (mm/sec)

Tks found more about the nozzle orifice land length in this thread: [forum.seemecnc.com]
He put the hot end in the freezer to help extract the filament intact from the nozzle orifice.
