    • 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.

        When all is said and done, $10K makes perfect sense from FFTEC. Though I expect that price will fall a tiny bit with time.

        PS your manifold looks awesome.
        Thanks man!

        Yeah, I don't know what FFtec charges to install their own kit, but when you start at $6750 for the whole kit (bottom mount), plus ball bearing upgrade, minimal exhaust work, MAC solenoid, 3.5 bar map sensor, etc., you're already at about $8k in parts. I'm guessing FFtec charges more than $2k to install.

        Plus you need to account for transmission upgrade costs whether MT or AT, motor mounts, transmission bushings ($400 from PTF), and probably another $500 or so just for extra fluids, and other stuff you may not think of. But realistically $10-12k gets most guys setup unless you go all out on the turbo and V-bands, SS oil and trans fluid lines, oil thermo delete plate, Meth SS lines upgrade, dedicated Trans cooler with more SS linies, and stuff like that...*cough*

        Planning on it. The backup car is DrN55 which would be a huge drop off. Jon @ BMS is racing our M5.

        Depends on the kit and what you include. A high quality turn key kit from FFTEC is probably around 9k installed.

On the street I bet it makes pretty good boost by 3000RPM, making it a TON of fun
        I honestly doubt this is the case, a lot of people are willing to spend $2500-4800(depending on options and who does the install) for 450-550WHP, not many are willing to spend $6000-$9000 for the same with a little more reliability. We actually have something coming soonish which should fit right in between these 2 areas.

        There are reliability factors as well. Single turbos basically get started where RBs max out. Ando is happy with around 500rw on pump + meth so for now the car will stay around 20psi.

        bingo

        $2500? Man, I did the math when I had my S2B2 pre-ordered, and with just upgraded thrust and billet wheel I was looking at ~$5,200 installed. That didn't account for replacing anything else or doing anything whatsoever. I understand you could do it on the cheap for maybe $4500 doing nothing else except turbo replacement.

        I'm also saying I see smaller turbo kits coming out for less than the current FFtec price of $6750, there's already a manifold available for $2k top mount, and you can get 550hp turbos for under $1k. So already it's feasible to have a single turbo setup better than stage 2 turbos with around 550whp for $5-6k. We'll see kits for $4k before long, I'm sure. That's why I said I can see stage 2 turbos becoming obsolete, they're only reliable at levels of minimal gain over stock turbos, and as more single turbo setups come available, the stage 2 market will just pretty much be gone.

        Not NOW...but in the future.

        Pretty simple math, you want stage 2's with no thrust of billet wheel, $2499. You do the install yourself, and you have some gaskets, etc. So you are very close to $2500 before install parts. $4800 is what those same stage 2's with no options would cost installed. Yes if you start checking options, things do get more expensive, and yes I do agree the single adds a lot of reliability, but it comes at a price. A $4K turbo kit sounds pretty scary to me. A lot of china would be going on.

        There is no doubt the single kits will get cheaper with time. How much cheaper and with what materials being used is another story. Big hp isnt cheap and to keep it reliable will only make it more expensive.

        Stage 2 twin kits i think will stick around for awhile. Ive been waiting to pull the trigger on a single kit for awhile now, but until more testing and tuning has gone on im still pretty nervous about spending that kind of cash.

        What i know is that I would be quickly disappointed with the stage 2 twins knowing 500whp wouldnt be enough for me.

        I did a few 3-4 shifts with the lvl10 at 20psi and they seemed OK. My private track isn't long enough for 4-5 shifts. So we'll just have to see how it does Saturday at ShiftSector. Car is loaded up and ready to roll. Click here to enlarge

        Starting at 50mph in 3rd it feels good to me. But the rubber meets the road at the runway. We'll find out soon enough. Click here to enlarge

        Yeah I made that mistake once. Showed up at 6pm and by 1am I had gotten 2 runs. I'll wait for a private day. Click here to enlarge

        That's sucks, plus you'd probably get kicked off after the first run anyway. Private day it is then.

        It's a great event but sponsorship is too much work. I'd rather just show up when I feel like getting there, help customers who happen to be there racing, and have fun testing our cars out. Click here to enlarge
