First video for me, not bad. Definitely in for the 2nd part and the driving impressions. One tip, pull the music back a bit, can't hardly hear what you are saying especially at the end.
Great video, lots of damm work! I have a 2012 x6 with the N55 engine, I am dreading the day I have to change the turbo when or if it fails. But I was wondering, wouldn't it have been a lot easier to drop the subframe and you would of had a lot more access to work on getting the turbo off and new one back in?
Oh absolutely it would have been easier to drop the subframe! lol you are correct. I just did not have a crossbar to do that, and most BMW techs don't drop the subframe because although it makes turbo removal easier, it also adds more time to how long the car is in the stall (which since most work on flag hours, this would cost them money). So I sucked it up and did it this way. Which honestly would not have been so bad if I could go higher off the floor and had the "questionable support jack" placed properly under the engine, lol
@@turbospool , did what ya had to do, got the job done and thats all that matters. last question, where do you find the torque specs for the turbo manifold bolt and associated bolts for teh cooler and oil lines? Did you prime the engine after you were done and how long did it take you to get the trubo out and new one in?
@@dappa311 i got the specs from my friends at the dealer. You can also find them online if you have access to BMW TIS from what I understand. Engine was primed upon completion, prior to first start. 1 long crank, 2 short cranks. Can’t really say how long it took me as I broke it up over 2 weekends and a few hrs here and there after work. Plus I was filming! That alone adds like 30%-50% more time to ANY project lol
Check Shuenk’s site. I believe this turbo is rated for just below what the PS2 can flow at max. It spools earlier than the PS2 though due to the proper manifold design without the restrictive neck at the turbo inlet that the PS2 has
My turbo drain line is leaking (2011 n55 xdrive). Do you think it's possible to replace just the line? If so, how difficult do you think it'll be? Thanks!
Absolutely it is. It’s a common leak point with age. I did it when i first got the car in 2019 and it’s easy to access on a RWD. I couldn’t tell you on the Xdrive though as that passenger axle bracket may be on the way. Hopefully someone here with an Xdrive can answer it for you!
how are you gonna show off those calipers and not let us know how we can get our hands on something similar... They were sweet brother... They dont look like covers if they are!
Haha thank Onigma! Go into my main channel page and check out my videos. I actually had to break up that front caliper upgrade into 3 parts. But they are factory BMW Brembos off a BMW G12 :-)
Wondering how you lift the engine with all the wheels still installed. First time doing the job and looks like theres extra information missing I need to know.
I mentioned that you have to support the engine, then unbolt the motor mounts (3 10mm bolts each), disconnect the charge pipe and boost pipe, and you can start lifting carefully
@@turbospool Ok I see, I thought it was just the top bolt that needs to be unscrewed not the whole engine mount. I thought it was only 1 screw on each side on the top where the support brackets to hold the engine. So, I need to also remove the 3 bolts on both engine mounts as well? thanks
Hey Rich? You absolutely want to have a custom tuner ready to go for when you go drive the car. It will start and idle no problem. But driving around it will be EXTREMELY easy to spool when the DME isn’t expecting it due to the design of the wastegate. So you want to get setup with David Shoup, Wedge, or Keahi Harris prior to install so you can at least have a base map that will allow you to drive it around safely while you tune it. This is not for the OTS tunes
Lol! I mentioned it in the Part 2 video. Next time I need to raise the engine I will use the engine brace from the top instead of this questionable method. I have one now lol
too early to tell! There's many dynos of the PS750 already. But only a handful of the F55 (even less that are finished tuning). But from what has been found on the F55 so far is that it has more "room for growth" than the PS750. Just based on similar dynos the F55's wastegate is in the 70-80% area whereas the PS750 is maxed out at 100%. Just on that detail I would say the F55.
No, my car is RWD. I’ve not messed with an Xdrive N55 yet so I cant say how and if it’s any different in this particular project. That would be a great question to post up on the Facebook N55 owners group
Turbo is doing phenomenal! No dyno yet. Changed my fueling setup a third time, so tuning once again has to start from scratch lol. But the turbo is excellent
Your best bet is probably going on the N55 Facebook group and asking for it there. Im sure a few have a blown turbo they haven’t thrown out yet. That would be the best case scenario
A big part of the upgrade is the less restrictive manifold. But you could I guess if you know how to weld. The manifold is one piece with the turbine housing (both on the stock and in the N55+). So you’d have to buy it, cut both turbines off the manifolds, then weld the upgraded turbine on to your stocker. Shuenk BACK IN THE DAY used to do “super cores”, which you could bolt into the stock turbine housing. But I’m not sure if they still make it since the N55+ came out. You’d have to check their site
Kind of difficult to answer that. Im going as high as my current fuel setup will feed RELIABLY- wherever that ends up. Then in the near future if I want I will do meth injection. Not going for all out insane build lol. It’s a daily driver with an open rear differential. BUT… Ill be happy to break 500 wheel horse power on this daily driver lol!
Rated for about 500 whp. But people have already gone well above that. I just finished 91oct tuning so in about a month I will go dyno this on 91 octane and see what it does there before going all out on E85
@@beamer2169 couldnt really tell you since filming and finding the best angles and lighting takes up so much time. If i had to do it again I can definitely do it until 8 hrs going at a steady pace with beer breaks. This first time without filming maybe took me 12hrs
