    • BMW F20 M140i testing new Pure Turbos Stage 2 B58 hybrid upgrade hits 586 rwhp on 93 octane pump gas

      This is impressive and shows what the B58 can do with a strong hybrid. Pure Turbos has a new hybrid B58 upgrade they are calling the Stage 2 and these results on a BMW F20 M140 hatchback certainly quality as strong and impressive.


      586 horsepower to the wheels at 19 psi of boost on 93 octane pump fuel:


      The HPFP apparently is tapped out but that still is a ton of power on the factory HPFP. The claim is pump fuel only without meth which would make this likely the strongest pump gas result to date.

      Before someone goes crazy about the torque figure the Dynojet is reading torque in newton-meters so 674 works out to 497 lb-ft at the wheels.

        Did they provide baseline so we can see the delta?

        The car did 415whp on bm3 ots stock turbo. Just turbo swap did 467whp on the same ots map. Stock it did 315whp.

        LOL. Really, We are doing the same testing currently, the HPFP taps out WAYYYYY before then. So you are telling me 93 octane only, 19 psi and almost 600WHP. Let me guess its in Europe right, please show me where you are getting US 93 in Europe. Who knows what fuel this is on. Where are the logs guys? Ubsurd claims of power on unknown pump fuel, with a stock HPFP that has no chance of supporting with no logs to back it up? Got it...

        For a little more info, our test car did almost 450WHP on the MHD, Mission, and BM3 OTS Stage 2 93 maps, but the HPFP does not have a ton more in it past that we found out quickly, we are slowly squeezing more out of it, but you really have to massage boost to do it. My guess is either an HPFP upgrade they are not dislosing, meth injection, CPI, or some other trickery, no chance the stock HPFP is providing enough fuel for almost 600WHP. They know we are close to releasing our units so its a mad dash for results, how they got them is anyones guess.

        To be fair tuners I speak to say the HPFP taps out way before this. As do people developing HPFP upgrades...

        I don't know why it's always PTF churning out numbers that don't make sense.

        The turbo hardware no doubt can do this but the stock fuel system on 93? How?

        Hey Tony,

        It sounds like you're jumping to some conclusions. This car has the new Z4 "TU" HPFP bolted on, which is why the HPFP is hanging so well. Below is a pic of a few other runs shown where the pump pressure crashed. She wanted to soar over 600whp! We are very excited about this turbo. Performance is phenomenal. As for the fuel clarification, Peter says it's his local 98 ron pump fuel. Which is very close to our East Coast 93. Either way, octane is not the limiting factor here. The HPFP is the limitation. Peter plans to re-dyno with the meth turned on within the next week. We have logs of everything. There's nothing to hide, this turbo is awesome! Feel free to ask the tuner, Halim about it. We pushed to test before Black Friday, didn't have anything to do with you, sorry.

        Here's log of his 6.4s 100-200 dragy run. Some traction issues in 3rd, so we expect it can do even better.

        Also here's what this turbo did on the BM3 OTS map, and log to go with it. Same tune just turbo swapped!

        I hope that answers your questions.

        Yeah the supra version of the bosch HPFP the "EVO 6" has been known to make crazy amount of power and still not drop in rail pressure.

        The pump is available on the B58C which is a Europe only motor, and in NA it is only found on the supra since B58's in NA are only found in the B58D version.

        Edit- there are some mini coopers, and bmw models like the x2 with this hpfp.

        Tony has limited himself to one post a day for the sake of not wasting time on the forums so I will reply what he gave me.

        "I was not jumping to any conclusions, simply going off what was posted. I agree it was Joe who posted not you guys so maybe the information was incomplete. We actually kept a supra pump on hand for this testing and swapped it in yesterday when dealing with the struggling stock HPFP. which is why we knew no chance you were on the stock pump. The upgrade takes care of the problem."

        Well why isn't anyone mentioning when this new Supra pump is utilized and what is the limit of that pump?

        Little more tuning, backed it up with 603whp on pump this morning.

        Its very well documented on bimmerpost, there is alot of testing data, and retrofitting guides.

        You can go full E85 on the stock turbos with this pump apparently, and 600whp is the upper limit on pump gas.

        It's 350 bar vs. 250 bar of the n55 hpfp iirc

        we also did 630whp earlier today on a race gas / 93 50-50 blend. More power is not possible due to hpfp dropping.

        Its not really well documented at all to be honest. There was a thread with posts as recent as yesterday with direct questions if the Supra pump even works on the B58. Some saying you need machine work etc. Was a lot of questions, and zero answers

        There is still alot of questions yes, however there is one Excellent thread regarding part numbers, where to source the pumps, how to modify it to make it fit, which B58 it's available on, what other BMWs it's available on, Bosch part numbers and pressures and even data logs of hpfp rail pressure. There is indeed modifications that must be made but there are also detailed measurements and even 3D printable templates that are made as well.

        So yes it's relatively new, but there is data and evidence behind it's capabilities

        Is this the new higher capacity one or the old one?

        Old is 3000 psi and new is 5000 psi, I think?

        The engine in the Supra Mk.V is the B58B30C while the engine in the Z4 MDrive 4.0i is the B58B30O1 .
