    • BMS E82 135i FFTEC N54 Single Turbo Kit Dyno Testing - 585 wheel horsepower

      Been racking up miles on the 135i and fixing little things. And finally had a chance to get to the dyno today for some baseline testing. As I've mentioned I've been VERY pleased with the FFTEC twin scroll top mount 5862 turbocharger kit. On road performance and spool is much better than any other combinations I've driven.


      Testing details:


      2008 135i Steptronic (original trans, for now)
      JB4 single turbo firmware & supporting flash
      FFTEC 5862 top mount single turbo
      BigTom intercooler, BMS OCC, BMS stat, etc
      Walbro 255 inline fuel pump mod
      Factory exhaust system (did not bother to open cutout)
      ~E30 mix for for 17psi runs. For 20psi+ runs enabled meth kit for fueling using a single CM10 nozzle.


      Notes:
      1) Was not going after any power records so left the tuning very conservative all around. At the same boost levels there is easily another 15hp in this setup with more advance. And no reason this turbo can't be cranked up to 28psi when the trans is ready.
      2) It made a lot more power than I was expecting. It's basically on pace with the 6466 at these lower boost levels only with much better spool.
      3) If the trans would shift this car would be seriously quick. I'll get to work on that ASAP.

        only difference is i have the vargas hpfp mod and rail
        I don't necessarily mean the numbers exactly he stated, just the general mindset. On most cars, the only way to run high E85 concentrations without meth is by leaning the AFR out and a lot of people don't really understand how much of an effect that can have on fuel volume.

        Just for kicks, E85 max power rich is a lambda of 0.71 (vs gasoline of 0.85), and E85's max power lean is 0.87 (vs gasoline of 0.9). Running high concentrations of E85 at 13.3 gasoline AFR (lambda of around 0.91) is actually leaving good power on the table, not to mention boatloads of potential cooling. Looking forward to see what Tony has up his sleeve to address this once and for all.

        Because of lag, you also make less torque down low where the HPFP is known to struggle.

        Is there a reason you're not winding it out to 7200? The way the torque-band is playing, it looks like you still have more in it just from bumping the rpms up.

        This car is just going to be freakin insane at the track.

        It's an auto. He can't rev that high.

        Yeah, I've never liked or used screens. I either run a filter or just no filter at all. With a dremel and rerouting the oil cooler lines there is plenty of room for a larger filter if I ever need it. As long as I keep this one clean it probably doesn't matter much at this point. The trans is a more pressing issue.

        It's great to see Terry get this kit up and running. I can't wait to see data at the track.

        @Terry@BMS the dyno run in the vid, open downpipe or closed?
        is it better for spool with open downpipe?
        how is the sound with the open downpipe? extremely load or reasonable

        Are you looking to do LVL10s torque converter swap? Or a full build of it?

        I know I speak for plenty of people when I say I anxiously await your results from the trans build. This car will absolutely destroy at the strip once you get the steptronic to hold.

        I thought level 10 was proven to not really be a legit upgrade? A couple of people have used them and yet we are still searching for a legit trans rebuild option.

        I know...it's weird I feel a few people have as well. The most well-documented one was lostmarine's and it was never tested fully. Who knows who has the car now, probably someone with just a JB or something and has no idea what type of trans work is done lol. I know there was another guy that did one and failed pretty quickly, but I also heard he did nothing except the clutch pack and didn't break it in and just let it rip at the trick right away; so who knows.

        I just think it's weird people still bring them up bc if it worked everyone would have it

        I've said it many times, until someone can reprogram the trans, your only half way there with a clutch pack upgrade

        Had my level 10 with Vargas stage 2 batch 1 running between a 65-75 additive on map 3 for almost a year now and have had zero issues. I know its not the power level terry is running but I've beaten on it daily and its fine with no hint of a issue. I did converter, va lvebody, and their rebuild kit.I had it on stock turbo for a while before I installed the vargas t urbos and I've been happy. It was over 7k with my local trans. shop doing install but I've been happy.

        7k... ouch. I hope it holds up!

        Try them out! Should work as their description covers what you need on that ST 135 Click here to enlarge

        Ouch is right...7K just for the trans+install? That's one of the reasons I sold my 335. To get to SC m3 speed you need to dump a lot of money into the 335. Btw, not to go to far off topic but anyone notice the m3 SC 625hp kits are now 9k? Makes the SC m3 option look pretty good!

        In terms of value for a very nice car the F10 M5 is hard to beat. Bone stock w/ a simple 5 minute install tune running 11.4@127.

        in a few years ill probably own one of these new M5's. But at 100k new they are a bit out of my budget. I would assume in 3-4yrs these cars will be ~40k-50k used. Then they will be a great bang for the buck car! Tune/DP's/E85 (maybe) and running 10's all day long. That's what im talkin about!
