• Over 500 whp already out of the 2015 BMW F80 M3? Yep. BMS JB4 tuned S55 turbo inline-6 ethanol (E85) testing shows 539 wheel horsepower

      So, um, yes, you can say the new F80 M3 and F82 M4 respond pretty well to bolt on modifications. Journalists are still getting their hands on stock cars to test but Burger Tuning (BMS) already has the car over 500 wheel horsepower. This is not too surprising as with a mild bump in boost on a beta Stage I BMS tune the car already showed 479 horsepower at the wheels. Now with some further refinement to the tune and some ethanol (E85) the result is over 500 whp.

      Here are the details in the words of Terry@BMS:




      Hey guys,

      Got back from a couple hours of dyno tuning and came back with some interesting results. This car definitely likes E85...

      The JB4 now has full electronic wastegate control in addition to the fuel mass control & CANbus, paving the way for E85 testing. The test car is our 2015 DCT M3, 100% stock with a JB4, with ethanol mixed with 91 octane at 30-50%.

      I've been running E30 for the last week on a tune that ramps up to around 25psi and I've been very impressed with it. On the dyno today running that same trim resulting in a very consistent ~510whp / ~510wtq results. Although the turbo holds boost to redline it looks like shifting around 6000 rpm will result in the best acceleration results as power noses off above that.

      While I had it strapped down I decided to explore more aggressive power levels. Added a little more E85 and went on an hour long adventure through many different curves and tweaks. Finally arrived at a 28psi peak tune which yielded ~540whp / ~575wtq. I've not tested this much on the street so we'll have to see how viable it is. But this just goes to show you how much room was left on the table for tuning with this platform.

      This car is an animal.

        wow someone finally made a drag radial in a 19inch huh .... thats awesome for newer model nissan turbo guys as well... good to know

        That's all those guys run 20" r888 at shift sector.

        How are fuel trims looking on the stock hardware with an E30 mix and the stock "self-adjusting" fuel trims (since I assume the JB4 cannot manipulate those yet). Also interested to hear how the Air/Water intercoolers are responding to the higher boost settings with IAT reduction.


        Awesome results Terry with a tune only car, would love to see some gains if it was paired with a full exhaust (i.e., the Gintani system they've been teasing on their IG)

        Can't you get the the MT ET Streets for a 19" wheel; I know 20" the options are pretty slim

        Yea I believe you can, but that's like the limit. I haven't seen 20" for MT or Hoosier.

        They have had them just in sizes that don't fit narrow body cars (corvette sizes, etc.)

        A 275/R19 would be awesome.

        These aren't too bad to be honest.

        The JB4 has full fuel control. As much as a piggyback can have anyway. Preliminary impressions are E30 looks good and E50 is sketchy. The most realistic scenario is you use E30 to get up to around 500whp. And then if you want to exceed that run race gas instead for up to 550whp.

        Will a meth injection set up be developed for this?

        Yea that's what I meant, 335/30/19 would be nice for sure which they've had but the 305 allows plenty more cars to use them in 19s, when I said Nissan guys I was referring to Zs, should have mentioned that

        @fastgti have you ever used a drag radial? Bc nt05s are many many moons away from even the worst drag radial on traction lol

        Nope lol. When I up the boost again and test it out with meth, I might have to buy a pair of MT for the rear. So far it's holding 19psi e40 mix no problem at all. I took off on my buddies e60 m5, second gear just ripped 2 cars ahead.

To match stock + $800 tune F80 M3 performance with an E90 M3 you basically need a 10k+ supercharger kit and even then you won't have as much torque or OEM like reliability. Now if you are trying to make a 600whp+ bomber then yes maybe the E90 is a better starting point but that can't be more than 1% of the market.
        Absurdity on many levels and a complete misunderstanding.

        Is the GT3 obsolete because Porsche releases a turbo?

        Is the E46 M3 obsolete now? The CSL? Is the 458 obsolete because Ferrari gave the California a turbo? Will the 458 Speciale be obsolete once Ferrari gives the 458 the same turbo motor?

        People who equate the better car to wheel horsepower never understood what an M car was (or is) anyway. This is mostly the N54 crowd, which is, well, you. The top performance option will always and forever be the E46 M3 over the F80 M3 and the E9X M3 over both.

        You guys are making a big deal over 500 whp. In the grand scheme of top BMW performance 500 whp is an f'ing joke. Are these great gains? Yes. But keep your pants on. You run this car against the big boys and you'll be wanting to come back with double the horsepower. Talk to me then.

        How can you make fun of the superior motor making more power with more capability?

        Oh wow you can gain horsepower on a factory turbo car. Whoopty doo.

        its time to see some v-box numbers + some races against other cars ,, 500+ whp is great but the question is how will it perform is the streets !
