    • Burger Tuning (BMS) N20 F30 328i JB4 Stage 2 Dyno Testing on E85 cracks 300 wheel horsepower - New World Record, dynojet graph.

      Hey guys, We've been working on the JB4 for the N20 motor (Stage2) for the last few weeks and have made some solid progress. Enough so that we finally decided to hit the dyno up to quantify things a bit. The results were very impressive. For JB4 development we've removed the ER downpipe so its now fully stock right down to the factory paper air filter. Only mod is the JB4 and a 50% mixture of E85 fuel and 91 octane (e.g. approx E40 fuel).


      Results: A new N20 2.0l world dyno record: 300+whp and 350+wtq!!! We did a run before we started on the factory tuning (only with E85 fuel) and hit 237whp. So gains were as high as +70whp (~90 crank hp) in areas under the curve.

      A few comments:

      1) We're not ready to release all of the tuning details but I will say peak boost was around 23psi (compared to 17psi factory), and in areas under the curve we were making as much as 10psi more than the factory.

      2) As expected the platform LOVES E85 fuel. Performance on 91 or 93 octane fuel will be substantially lower but will be stronger than Stage1 power levels. In the coming weeks we'll be posting dynos and additional data on 91 and 93 octane.

      3) During testing we opened up the airbox to simulate a high flow intake and determine the potential for intake power gains. In doing so we found exactly zero horsepower gained even at these high boost levels. The factory airbox is simply not a restriction at 300rwp. For this reason we suggest you use only the factory airbox with the N20 platform. Companies claiming gains with intakes on this platform are fooling themselves and/or you.

        wow, nice numbers!

        What turbo is on the stock 328?

        And Dammit Terry get over to the VAG world already, I want meth integration!

        Never heard of them and with no dyno I wouldn't even pay attention to them. This is legit from BMS.

        Can't you say the same thing about the N54?

        no... the n54 can hold 2.5 times its stock power on stock internals and makes 425 whp w basic boltons and e85... this doesnt even come close... even for a 4 cylinder motor

        You realize this is just getting going right and already cracking 300 whp?

        it took the n54 4 years to give e85 a shot... this thing is near maxed out at the gate because the turbo is a near immediate limitation... bmw purposely created this 320i / 328i nonsense...

        Right but if it's cracking 300 whp on a small turbo that is an increase of almost 80 whp over stock right there. So it's pretty damn impressive that is more power than an E46 M3 S54.

        Color me impressed. And when it gets a real turbo...

        Is it the same engine in both the 320i and 328i?

        Apparently even the turbo seems to be the same.

        So is the 60hp difference just with the tune. If so, why buy a 328i?

        That other small banger produces over 300 grams of CO2 !! my car now is under 5 sec. with only 260 whp and still i do 700 km with single tank (computer managed to read 1200 km range till I hit intown ) and i bet i can squeeze more with same 150 grams, this engine is about efficiency still amazing how much performance with this amount of hp

        as far as i and many others are concerned, the efficiency will kill this company and its enthusiast fan base
