    Harrop Engineering releases short teaser of their Eaton TVS1740 positive displacement M3 S65 V8 supercharger kit running

    The last time we saw the Harrop Engineering TVS based positive displacement supercharger kit was back in May of this year. In that article it was mentioned that a lot of work was still ahead especially in the area of tuning before this kit would ready to be released. Harrop Engineering clearly has been working on it and posted a teaser video you can see below showing the kit running on the S65 V8 with an M3 on the dyno.

    Unfortunately, no further details are provided with the video which just shows the wheels moving. No dyno figures yet but this is a complicated process and there is a reason nobody has brought a positive displacement M3 kit to market. It's very, very hard to do.

    Pricing is expected to be in the $12,990 area with a release this Fall.

    The main thing to take away is it's still coming and according Harrop relatively soon. BimmerBoost wishes them well and wants to make it clear when this comes to market it will be an achievement worthy of great respect. Good luck to all involved.

    I definitely want to see the torque curve on this thing.

    Going to be a ton of fun to drive. I want to see the torque curve on the turbos too though.

    Same here! I bet this setup pulls hard down low. I don't see this being a very good turbo platform though...

    why not turbo ? 11.5 to 1 is high just needs to be tuned right and not going for any huge power but a low comp build motor would be a beast. with 3 different types of boost soon to be had for the s65 people can pick what works best for them.

    Don't get me wrong I would love I see this happen, but I feel like there's a reason no other tuner has even givin it the time of day really. I see possibly reliability issues, running problems and turbo placement seems suspect from what I've seen.

    The motor in itself isn't the problem, it's the material (Alusil) is known to have block flex problems, there's probably a ton of space issues (custom exhaust manifolds to mount the turbos pre-X pipe) and cost:

    Supercharger:
    1. 1 Supercharger
    2. 1 Bracket & Belts
    3. 1 Manifold
    4. 1 FMIC or Heat-Exchanger (and plumbing)
    5. BOV/Recirc Valves
    6. Tuning -- Much easier to adapt an SC to a non-FI car than a turbo


    Turbocharger:
    1. 2 Turbos
    2. 2 Custom Manifolds
    3. 1 FMIC
    4. 2 BOVs
    5. 2 Wastegates
    6. 1 Electronic Boost Controller
    7. 1 Manifold
    8. Injectors / Possible Fueling Upgrade
    9. All Necessary Vacuum Lines to Run WGs & BOVs
    10. All Necessary Lines/Tapping to Run Turbos (Oil/Oil & Water Cooling)
    11. Tuning in Conjuction with Electronic Boost Controller


    IF it's done right, the S65 would be really cool turbo'd. But we already know it's gonna cost more than any of the supercharger options, it won't really shine unless it's on a built motor & even though the Rotrex offers a lot of low-end TQ, the Harrop is going to going to fill that void for people who want insta-Tire Roasting-boost with a TS blower

    I know what the blocks are made of I've specialized in BMWs for 10 years and yes when you get to a power level sleeving the block needs to happen. Im not saying its a better kit or better way of boosting a s65 or cost affective. i love seeing new things for this motor the Harrop kit looks clean and should be a beast and this TT kit will be cool but it will take a ton of money, time and talent to make a retail-able kit but there will always be someone wanting big power or "look I have twin turbos " I just want to hear a TT s65 Click here to enlarge

    Why wouldn't it be a good turbo platform?

    You're spending over $15k either way (tax, install, etc.) so who really cares about a few grand here or there?

    Shouldn't you know the compression ratio of the S65 then?

    People looking for a value should play elsewhere other than with boosted E9X M3's. If deciding between new kits once again a few grand here or there does not matter.

    Will turbos be more money? Sure, but not much more.

    Nope, all street S65's are the same compression ratio. Try again.

    Look it's fine but the S54 was 11.5:1 and the S65 is 12.0:1 just like the S85 as it shares the same basic internal components including the bore/stroke. The GTS motor doesn't change the bore just the stroke with the same compression pistons.

    Yes... as far as value goes if one looks at buying an E9X M3 + going supercharger route one THEN thinks they should wait and see what happens with the new M4 and it's competition (new Mercs, C7 Vettes etc)....

    If the M4 is as good as projected I would have a hard time forking over the $40k+ for a good used E9x M3 (08-09) and then another $20k for the S/C and mods when a better solution on a brand new car with turbos may be available very soon...

    Either that or buy one of the already modded M3's that will be sold in the next year or so with an already successful platform

    A turbo E9x M3 would be interesting development or a S/C solution with real low down torque... anyway you slice it it is an exciting time in the M3/M4 world

    problem is some people like the V8 over I6

    and as far as a S/C with tq down low. ill take that challenge , because mine does Click here to enlarge
