    Thumbs up NY98M3's 2017 Build Thread - M52/S52, 6870, AR Designs, E85

    2017 is the year to shine, going with some changes because....well....why not, it winter. Kicked some ass last year at Pocono. While we kept up with the big boys, the car gets zero looks until it goes over 160mph in the 60mph to 1600ft.

    Plans:
    Built 2.9~3.0
    Wiseco 84.5mm pistons, 8.5:1, coated skirts
    HD wrist pins
    Total Seal Gapless top rings
    Pauter Xtreme duty rods
    S52 crankshaft
    ARP2000 10mm headstuds
    Schrick 276/270 cams
    Supertech valvetrain
    VAC/ATI damper
    Converted OBDI valve cover
    E85 everything

    Precision 6870 twin scroll 1.0 A/R
    AR Designs V1 manifold
    Twin Tial MVS 38mm (open dump)
    3.5" exhaust with cutout
    Treadstone 1245 intercooler
    Tial 50mm BOV

    E46 M3 6 speed trans
    Clutchmasters 850 twin disk with lightweight steel FW, race clutches
    Hydraulic TOB
    UUC Euro Evo3 short shifter
    Shortened DSS driveshaft

    Block is being machined, entire rotating mass is being balanced, just waiting on them to call and say it's done. I have a severe problem collecting M52B28 blocks, I'm up to 4 now lol.

    For the meantime, I used a spare block to measure up the new driveshaft specs.

    New fancy valve cover so I can stop melting my plastic OBDII cover.

    Interesting. After some quick research it looks like i'd just have to switch to the s50 coil packs and this would just bolt on?

    Be careful just swapping to s50 cover. The grounding system on that cover is not nearly as good as the s52 cover. If you make the switch definitely ground the coil packs to a chassis ground

    Having some 2nd thoughts about using the Lightweight steel flywheel.

    Clutchmasters states on their site the weight of the FX850 with the steel flywheel is 22 lbs total. I weighed it myself and saw that it the total package weighs 30.4 lbs. I think that might be way overweight. They have recognized the info on their site is wrong and are willing to swap the lightweight steel flywheel for the aluminum.

    What do you guys think?

    Isn't the gear rattle pretty bad on the 420G with a lightweight flywheel?

    What do you consider heavy?

    From what I found online, the stock DMFW weighs 26 lbs and the clutch is 15 lbs making it a fatty at ~40 lbs. With the Clutchmaster FX850 with lightweight steel FW its ~30 lbs. The UUC twin disk comes in at 25.5 lbs.

    Stock DMFW is heavy but quiet. I've had gear rattle for almost ten years now. I'm use to it.

    What are your power goals and how much boost will you top out at? Sorry, I know it's OT, just curious!

    Power goals are a reliable 950whp/800wtq. 32-35lbs of boost.

    Thanks, closely following yours as well. What does your new clutch package weigh? I see you're using a lightweight steel FW as well.
