    Is it me or do the superchargers for the s85 v10 underperform?

    Looking thru dynos it appears that supercharged s65 m3s gain much more percentage wise in terms of power than supercharged s85 v10s.

    Now that ESS makes supercharges for more platforms I believe its even more apparent despite running similar psi levels. You would think that with the extra 1L and 2 cyl, the v10 m5s and m6 would make some monstrous #s but I havent seen any.

    Well the S65 has great set of headers. Perfect as Super Sprint told me the other day. The S85 on the other hand, can breathe much better with aftermarket headers and it's a big plus for the S65 when going FI.

    But the problem is the blower ESS use. They are using the same blower that their S65 kit has even though with the S85 it needs to move ~20% more mass of air. This means less efficiency and less HP.

    Surprisingly, the best "bang for buck" HP mod for the S85 might be the Dinan Stroker

    The problem with the S85 is the small space. It needs a bigger blower than what people are using currently.

    Also, the S65 does have much better headers.

    Then currently available option would you go for? The G-Power is a phenomenal setup, but so pricey. ESS' kit doesn't offer any worthwhile gains. At least with the Dinan Stroker you get a legit bump in HP and get to keep the N/A setup.

    Considering the lack of aftermarket development the S85 has in comparison to the S65, I'd consider the current output acceptable. The E92 certainly deserved the focus prior to the E6x as it's a more profitable market for tuners. It will take some time but hopefully we will see this further developed and others will get involved with supercharging the S85 (cough cough @evolve) Click here to enlarge

    To the best of my knowledge, the SMG is the weak point openly discussed with the S/C setup. Apparently some sort of safety like feature dramatically slows shift speeds past 8000rpm. This was clearly evident with graphs from Vbox runs.

    You are absolutely correct Click here to enlarge

    S85 VT2-650 specs :
    Vortech V-3 SI
    Boost pressure: 7 PSI
    Horsepower on 91AKI/95RON: 650 SAE (30% gain over stock)
    Torque on 91AKI/95RON: 460ft/lbs
    Correction factor for drivetrain loss is 15% above RWHP as seen in dynograph (RWHP/0.85)

    S65 VT2-650 specs :
    Vortech V-3 SI
    Boost pressure: 8 PSI
    Horsepower: 650 SAE (~56% gain over stock)
    Torque: 415ft/lbs

    Correction factor for drivetrain loss is 15% above RWHP as seen in dynograph (RWHP/0.85)

    ESS VT2-650 w/ DCI (Dual Cone Intake)
    Evolve Tubular Headers
    Evolve Custom Tune

    The stroker makes less power and is so expensive it's out of the game completely IMO. $28,000 is the current "special offer" on Dinans website.Click here to enlarge

    If I had unlimited money, I'd stick with the setup I listed above. The one alternative I would consider is a stroker kit from PPM Racing and a S/C. The last time I emailed them they said $8500 for the 5.8ltr kit. Apparently they supply this kit to "well know" tuners in Europe. Who really knows though??

    As for G-Power.. I'd rather throw a couple more cars in my garage than spend that kind of change for some boost.. Click here to enlarge

    G-power kit is very nice...

    I have experienced the ESS kits first hand, they do providean incredible surge up top, especially with headers.

    Looks like the blower type is the limiting factor...I had a quick comment to evolve a few months back who suggested that they may do an s85 supercharger. Do you think their rotrex sc would be a better fit for an s85 v10?

    No the rotrex is too small. I would go procharger f1-x style on the s85.

    F-1X Procharger would be serious.. I wonder where the power limit for the SMG is though?

    I think Spec has the only available option for SMG currently.. A friend has issues with their unit on his 6-speed M6 coupe. I'm not sure if its a hardware or an installation issue though? I'll look out for some positive feedback from someone that installed it on their SMG.

    I don't doubt this but it would just take some more involvement to get a solid high power option. It's nowhere near as difficult as say a DCT.

    Yea, ive been on the M5board, not a lot of aftermarket products available. And not a lot of technical guys on the forum at all. I guess the small market brought along a small market of customers that aren't too much into aftermarket and or technical. I think a supercharger for the S85 with a nice pair of headers from evolve, would make solid numbers. There very little SC kits and guys who run them to there full potential on the S85 I feel.

    Trust me I know, I'm going to have to destroy some of them on video in a goal to educate. One guy is claiming to do an ESS built motor setup and thinks he will be untouchable. Wont he be surprised when an M3 runs away...

    All fanboys are annoying. M5 fanboys aren't an exception, but i got to say N54 fanboys are the worst following by Mustang and M3 fanboys.

    You mean ACG? He's a cool guy. Never claimed anything about being faster or whatever AFAIK.

    I don't know if it's him, but there are several there who think they are untouchable whether it be with a stroker or whatever. Gustav's videos have filled their heads with dreams.
