    MMP1k N54 twin turbo kit said to support up to 1000 horsepower

    I'll do an article on these later but... 1k? Can anyone verify that?

Because of this, these turbos have been designed and built from the ground up to minimize backpressure and maximize power.

    The manifold has the largest collector on the market and the AR in the turbine housing has been optimized for max power for the 46mm turbine wheel and 46mm compressor wheel while maintaining excellent spool which is basically imperceptible when rowing through the gears compared to stock turbos. The compressor wheel is a GTX style 11 blade extended tip 46mm inducer forged milled billet wheel optimized for high horsepower and we are the only turbo manufacturer bringing it to you for the N54 on the market.

    The turbine wheel is a high flow 9 blade with 46mm exducer made from high strength and high temp resistance inconel alloy material. The turbine housing and manifold are made from high strength stainless alloy with very high temp heat resistance and casted using a high precision investment casting method which also yields a gorgeous surface finish. The wastegate parts in the turbine housing are all new and machined from high strength stainless alloy.

This will make sure the turbos are flowing to their maximum potential along with the upgraded plumbing for the turbo.

    The turbos are made from a full native TD04 bearing housing with upgraded TD04 thrust bearings which include double the surface area compared to the stock TD03 thrust bearings (that's 100% more). Other popular hybrid turbo manufacturers use a stock TD03 bearing housing with TD03 journal and thrust bearing components and smaller TD03 shaft size and just cram much larger turbine and compressor wheels in stock compressor housings and stock bearing housings never meant for the small TD03 shaft size and small TD03 journal and thrust bearing components. This can lead to shafts breaking and premature wear of the thrust bearing causing smoking issues on the turbos. All these issues that give hybrid turbos a bad name on the N54 due to improper design has been solved in the brand new TD04 bearing housings from MMP. The MMP design uses a thrust plate with 2 oiling ports vs one in the standard thrust plate and also the thrust washer and collar have 2x the surface area of the TD03 components, this is why they are MUCH more reliable then those other offerings. These great upgraded and reliable thrust components for 30psi+ are included standard with no extra charge in all MMP turbos.

    I like what I read.
    The manifolds are single-wall?
    These look like they should be stiff competition for the GC/lite series from VTT.
    is there any difference in comp housing clocking between vehicle models?

    Single wall cast iron, not exactly good at keeping heat.

    From my experience buying MMP S3s for my 135i, he clocked them for 335i and sent 335i outlets. I had to slightly reclock them for the oil drains to reach.

    Wouldn't that also depend on how thick the wall is ?

    That would be pretty impressive to gain ~300hp in potential (with the new cast housings) while retaining "quick" spool characteristics. 10's were elusive prior but this sounds like they'll soon be achievable in Reverse.Click here to enlarge Wonder if anyone has them installed yet?

    Gaining 300HP in potential? How are you getting that? More like an extra 150 whp. MMPs have already put down over 700 whp with the stock manifolds. Mauricio has said these are capable of 850WHP and using a standard 15% drivetrain loss, that's 1000 HP crank, that's where the number comes from.

    he has said these have a different A/R (not disclosed) and they should flow the full potential of the wheel (I forget the lb min rating so I don't want to misquote).

    It's also stainless steel, not cast iron.

    It is not stainless steel, dont let the ceramic coating color fool you.
    VTT GC turbine housing are stainless. Clear difference in material.

    Sure it matters, but still way inferior to the stock double wall manifold.

    I don't think double wall manifold is feasible at higher whp levels. You won't see any upgraded double wall manifolds ever.

    So even though he lists it as stainless steel, you say it's not? Why would he lie? That would be easy to counter once the manifolds are in customers hands.

    MMP offers what they claim are the most powerful N54 twins on the market - MMP1K TURBO KIT offering up to 1000 horsepower

    Twins breaking the 1000 crank horsepower range on the N54 platform would be huge news. That level of power from twins was promised from a handful of vendors for years but nothing came to fruition at least not until now.

    Click here to enlarge

    Will this upgrade from MMP be the first to do it? Perhaps. There is not yet any proof of that level of output from this upgrade but it certainly looks like if any twin turbo N54 upgrade will do it the MMP1K is the best bet:

    MMP has the best twin turbo system at the best bang for your buck for this horespower level. There is no more core fee so your stock turbos are not needed to be returned anymore and I wont be buying anymore at MMP as we will switch to manufacturing turbos with our new proprietary castings exclusively.

    The kit requires upgraded inlet pipe system (filter to turbos) and also outlet pipe system (turbos to intercooler connection) optimized for the high flowing native 19T compressor housing which is over twice the size/flow of stock compressor housing and has 2" inlet connection and 2" outlet connection, much larger than the stock turbos and even other large size hybrid turbos from the competition.

    So who is going to push these to the limit and find out?

    42lb per min compressor. N54s typically can get 10whp per lb of flow on e85. On a built head and cams you should be able to hit 850whp max

    So 1000hp with 15% drivetrain loss is = 850 .

    VTT GC turbine housing are stainless. Clear difference in material.


    Sure it matters, but still way inferior to the stock double wall manifold.
    Since we're talking difference of material here - VTT has updated the GC manifold and turbine housing from stainless to D5S ni-resist cast iron. I don't have direct experience between a comparison between the 2 materials, but from what I've researched, stainless improves spool slightly due to increased EGTs. Not sure how true that is, but right now the new MMPs are stainless, current GCs are stainless, new GCs are cast iron.

    Cost cutting probably. I do agree, VTT should have stayed with stainless.
    As for MMP, good choice of material after all. The prototypes were cast iron, maybe he decided to switch afterwards.

    So even more cost cutting and even cheaper material?

    Plus it's heavier?

    Just a FYI, Garrett uses D5S. It's more expensive to cast than stainless and there is more to it than just material density. When all is said and done the New GC's weigh a few pounds less than the previous generation. More info coming soon.

    That's only true with their smaller offerings, isn't it? They list stainless turbine housings for the GT55 series.

    Well good to know it is a bit lighter.
