    Hey, everyone. My names Dimitris, I'm one of the other beta testers for Propulsive Dynamics. I'm new to this forum, been on this platform for 3 years now just about.

    I'm a SoCal native, hailing from Downey, CA. I own a restaurant in Montebello, CA where we hosted a premeet for Bimmerfest which some of you may remember. Because of the restaurant though, getting on here and making informative and in depth detail posts will be difficult for me, especially now during the winter time when we're the busiest. I'll try to chime in and provide details as much as I can when time provides.

    Currently in the process of retuning and dialing in the car a process which @CKI and I are going through right now.

    On OTS BEF car made [email protected] in 92*/26%Humidity ambient temps at 105*IAT.
    25psi made 624 24psi made 620. Heat soak was killing the dyno runs so we estimate it was at a little over 680 if we dynoed in current temps.

    Since Chris and I are working on tuning everything timing has been dumbed down a lot so estimate currently putting down 560 or so.

    I don't have any solid data to provide right now, but the shifts are amazing. Driveability is smooth, crisp. Shifts are akin to an AMG shift.

    Here is a copy/paste from my initial reports when I first installed the trans.

    "Keep in mind I am going easy still even though adaptation process is complete, I want this to be running as smoothly as possible before going full retard on the turbo side.

    1) Very noticeable change in shift dynamic.
    -Roll in on second from a stop isn't as sloppy from stock trans, requires more pedal input to start rolling
    -Shifts are buttery. Fluid. There seemed to be a power loss on the stock trans at upshift, Where you'd notice power drop then jerk forward. No longer..these shifts occur so quickly that you almost don't even notice the shift.
    2) Change in low gear behavior
    -1st/2nd have a completely different feel. As do all gears really, doesn't feel like the trans is in a constant state of slip anymore. But low gear pull is completely different. Did map 1 WOT pull in 2nd and damn near blew my tires off cause all they wanted to do is spin. (Normally had at 15psi to KEEP traction).
    3) Change in the exhaust note
    -Not that this may matter to anyone, but it's something I noticed. Exhaust note has significantly changed. Probably due to the fact there's increased load throughout the system. Couple upshifts from 2->3 have had a sound similar to that of a DCT fart, very interesting to say the least. Lol.
    4) Change in how the trans behaves when placed into park
    -When being placed into park the car barely moved forward or back, even when on an incline. Stock would have very noticeable play. Does this make a difference? Maybe to some, my car is fairly low so for me it's a big deal when parking I don't continue moving into the curb if I get too close. (Yes I always e-brake)

    These are just some early changes for you guys. Everyday driving scenario. I put about 30 miles mostly normal driving yesterday so information will keep coming as I continue to drive and get everything worked in. Then I'll be creating a new thread with some review info, real world application, rolling/standing/etc with videos, logs, and GoPro footage.

    Before then, I'll add to this thread as I slowly acclimate everything.

    Cheers!"

    Since then, I have put in quite a few miles, as well as numerous logs. Which I'll talk to Chris and find which good ones out of the bunch are and post up more intricate details of everything. I have been so swamped with the restaurant I don't have much to provide besides my personal experience and those. I have my vbox setup, still trying to figure out how to use the vbox sport. More pics, video, logs, and graphs to come. Hope this holds you guys over till I can accommodate things at work.

    Best,
    Dimitris

    Nice Dimitri. Sounds like the most time consuming part is done, now just enjoy the car and take some mental notes for us. Looking forward to the 1k mile update.

    Well I've had this in since the second week of October, I've put over 1000 miles already. And
    all it did was run better. Especially after breakin, then now working on the tune--flawless. I have some race videos with some cars I'll post up. And when I have the free time get some drive videos. Takeoff, downshift, upshift, the whole 9.

    My car build is pretty much headed towards the same direction as your build..
    I can't wait to break in my pure turbos and start tuning.
    Met you at the Bimmerfest pre-meet. You should definitely host more meets there!

    looks like the new frictions hold better than expected. Any damage to the driveshaft?

    Oh wow, this is good and bad. Good, it wasn't the transmission, bad, more delays on seeing what you can do

    The axles? No damage. I'm running DSS axles so I doubt they'd receive any damage. Obviously the stock connecting part to the axle couldn't handle it lol.

    The driveshaft, haven't seen anything yet. I'm trying to get a Carbon one to get rid of that as a weak point. Very glad it wasn't my diff, but at the same time diff is going to need to be opened up to replace this part. But I'm trying to see if there's other options before sticking a new OEM part back in and have to worry about this again

    What needs to be done to make that happen?

    No, I've launched previous times before. I was at a stop sign during rain, went over paint and decided to give it some gas, car squatted and then big clunk happen. Was still able to drive the car back home, it was grabbing on and coming off. I assume it's been this way for a bit, notice some pull in the way the car drove.

    @AD-ENG
    I believe the kit is 3k for a custom 1 piece driveshaft, dss 1kwhp axles, all of the brackets/mounts for it to work. Then you need an irs 8.8 out of an 08+ explorer 3.55 or 3.73 gears.

    Thanks @Sshec152
    I'm gonna try and get in contact with @MFactory see if maybe they can make a hardened output flange or harden the OEM one. I'd prefer to get this going quickly rather than diving into a complete conversion to something else.
     
  17. Thanks for posting this update Dimi. Sucks you're down hard now.

    So, this is how it looked like inside the diff once he popped the part out. Can you say traction?
