Testing the Samsonas RWD6 sequential gearbox in the M4 GT4 build! Part: 2

Here it is guys! Testing of the worlds first sequential swapped F8X!!!
First part of the video I go over the parts installed, the GCU, gear oil pump, air tank, and compressor. I also go over the GCU software showing the setup and adjustability.
The videos of shift testing and pulls were done on a low power/ low boost setting 450-500whp to dial in the transmission and also break it in properly. For the part 3 video coming up I will be running the normal power level this car sees which is around 650-700whp. I will also be track testing the box for the first time and fine tuning throttle blip downshift adjustments.
Special thanks to Jake at MHD tuning and everyone involved with the custom coding!!! This enabled me to send a cut signal to my factory F8x DME to unload the gearbox and initiate the sequential up shifts.

This channel needs way more views

[@sonicnofadz]

this is so freaking wild, you are doing shit no one else is buddy, hats off to you

[@Cal-oh2kc]

This is the coolest thing ever

[@user-ki8zf1rp1e]

This is absolutely wicked🔥. Appreciate you guys at 4N Motorsport for bringing innovation to the BMW platform. You mentioned adding an accusump earlier in the video, for someone with a more street focused interior, would mounting it in the trunk add too much of a pressure drop?

[@Respect_N55]

Sickest build on the F8X chassis! Can’t wait to get an N55 up on the channel at 9k RPM 🙏😅

[@SOMNIOHM]

_Unequivocally Siiick!_

[@TheGreener121]

Awesome! I feel like these Samsonas are by far the most streetable sequentials... if only this stuff was cheaper tho haha

[@F80Ho]

Insane 🔥🔥

[@slopetechno]

[@exemch4826]

[@CAF-te3sl]

Can’t wait until you release the beast on track

[@amirlandarani8196]

Would love to see a build summary

[@Brolik809]

I love your settup

[@momoski5757]

Nice

[@alextasarov1341]

It just sounds so good

[@jackclement3941]

This is fucking gangster

[@CAF-te3sl]

The only difference is that the car runs on petrol not coke.

[@Andy-iw4xu]

Sick 🔥

[@Wxvne]

can we get some outside sound clips?

[@4nmotorsport]

Yes definitely! For the part 3 video I am setting up rpm hold/ 2 step launch control and raising the boost back up. After that I will get some outside sound clips 🤘

[@Wxvne]

Excellent bro👏🏽
Love the build and also those other single turbo s55 builds

[@bobbyhummer]

How long is the supply line ????❤I have a new dream

[@plan9203]

Your car was a DCT right? Did you have to add a manual clutch to make this trans work for starts and stops?

[@4nmotorsport]

Hey! Yes it was a DCT before and it now has a standard manual clutch pedal for starting/ launching the car and stopping👍
Having a manual clutch pedal with DCT shift speeds is a great feeling 😂

[@mixxeerr]

Is this the EFR 8474？ Looks slightly laggy?

[@letsseepaulallenopinion3217]

How do you achieve 8k rpm? Reliable?

[@fokjohnpainkiller]

How did you raise the rev limit? Was it on a stock ecu?

[@SebastianDisch]

NEXT Video BRO :D

[@wolvesbrigade1700]

What’s the final drive ratio for this setup ?

[@luchodovidio7202]

So you are using 20ms between gears??

[@BPF80MCar-vi1pg]

Im guessing , did your car come with a DCT

[@TrackdayRay]

Does MDM still work?

[@4nmotorsport]

Yes! However I don’t use it on the track or even on the road I keep traction control off

[@TrackdayRay]

@@4nmotorsport Same lol. Sweet set up.
