    • Another contender enters the E9X M3 S65 V8 supercharger ring - Evolve Automotive supercharger kit teaser

      The reveal of this information did not go exactly as planned as BimmerBoost vendor Evolve automotive wanted the reveal to take place here. Unfortunately, certain competitors got wind of Evolve entering the hotly contested E92 M3 supercharger market and set out to do their typical discrediting of competing products. It is for this reason that Evolve wanted to stay away from any other sites and do their reveal here. The official reveal may have been spoiled somewhat but here are the details on the three upcoming versions of the Evolve supercharger kit.


      There will be intercooled and non-intercooled versions. When speaking with Sal from Evolve during development BimmerBoost put emphasis on creating a non-intercooled version. Salman stated that he believes the S65 is extremely temperature sensitive from what he has seen from testing and did not necessarily like the idea. However, BimmerBoost believes an entry level alternative is necessary to what is already on the market. After some debate Evolve decided they will offer a 4-5 psi non-intercooled entry level kit.

      All Evolve kits use a Rotrex C38-91 supercharger. This is the largest supercharger in the Rotrex C38 range and it flows 11% more air than the C38-81. The RPM limit on this blower is 90,000 rpm, higher than any S65 V8 kit using a Vortech blower. No other kit features a Rotrex blower.






      This is the C38-91 compressor map:


      The C38-91 retails alone for $2595.

      [email]Sal@evolve has made a big point about the cooling when supercharging with this motor. That is why the plenum design is innovative and features a larger volume than competitors. The design of the kit is built around intercooling and not charge cooling.

      8 psi is good for the ~625 crank range. Here are dyno graphs at 7.5 psi on pump gas with the Evolve exhaust system:

      Flywheel:


      Wheels:


      Evolve has tested up to 9 psi but believes anything higher than 8 is pushing it on the stock internals with this blower. Production kits will feature 8psi for markets with fuel to support it. Here are graphs at 9 psi:




      The kit will be available for export and will be available for 91 octane fuel like what is available in California. The kits for 91 octane fuel will feature about one pound less boost, so 7 psi. Here is a rundown of the currently planned kit offerings and specs:

      Hardware:

      Rotrex C38-91 Kompressor (1100CFM)
      Self Contained Lubrication System with separate oil cooler
      High Tension Belt System with 270 DegC Belt Wrap
      Teflon Coated CNC Machined Billet Aluminium Bracket
      Teflon Coated CNC Machined Billet Aluminium Bracket Kompressor Bracket Housing*
      Teflon Coated CNC Machined Billet Aluminium Plenum with Optimised Velocity Stacks
      Teflon Coated CNC Machined Billet Aluminium Lower Bank 2 VANOS Cover
      Aluminium Crank and Water Pump Pulleys
      Evolve/ITG High Flow Foam Maxogen Filtration System
      8 x Bosch Motorsport Fuel Injectors
      Front Mount Air to Air Intercooler
      Boost Hoses
      Silicone Hoses
      Clamps
      Brackets

      Engine Management System:

      Calibration optimised both on dyno and road under various weather conditions

      Recalibrated MSS65 DME with optimized
      Fuel
      Ignition
      Torque Calculation
      CAM Timing

      Calibrations for 91(US)/95(EUR) + Octane Fuel

      Systems available:


      Non Intercooled 500-530HP System @ 5 PSI ---- Not Sure we want to release this yet! This is the one that needs the most amount of testing. Not happy releasing anything non intercooled.
      Air to Air Front Mount Intercooled 580-600 HP @ 7 PSI
      Air to Air Front Mount Intercooled 600-630 HP @ 8 PSI

      (Boost readings are taken at plenum)

      (Note Power will vary and will be heavily dependant upon ambient temperatures as the S65 is very dependant upon combustion temperatures)

      *Reduces Stress on Tensioner Pulley and has a secondary function of protecting injury from belt


      Below are some additional pictures. Keep in mind the bracket is engineered from high grade 6082 aluminum that will additionally be coated with xylon/teflon. It will be able to handle all the rigors of supercharging without flexing whatsoever. There are no spacers used in the bracket.

      There is also no cutting required for the front mount intercooler.

      Expect more details in the coming weeks as the kits near completion for production.

        There is actually a reason why which will be explained later and it's got nothing to with CFM or power.

        Just some additional info as we have been asked about the Rotrex blower a few times now.

        Rotrex is used on the following:

        Novitec Rosso Ferrari 360 Supersport 606HP (Twin C30-94)
        Novitec Rosso Ferrari 430 Evoluzione 707HP (Twin C30-94)
        Novitec Rosso Ferrari 430 Scuderia 747HP (C38-81)
        Novitec Rosso Ferari 430 Supersport 707HP (C38-81)

        Koenigsegg CCX 806HP C38-81
        Koenigsegg CCXR 1018HP C38-81
        Koenigsegg CCXR Trevita 1018 HP C38-81

        RUF Porsche Boxster 430HP C38-71
        RUF Porsche Carrera 2-4 445HP C38-71
        RUF Porsche Carrera 2S-4S 465HP C38-71


        The Rotrex comes with a very good warranty and given we are underspinning it, it will be a very happy with the engine pushed to red line all day long.
        Wow, I've seen the Novitec 360 kit but assumed it was all custom, including the blower. It has a good reputation at the 8psi range in that motor.

        CF can be an option but you know how we are with carbon yes? Pre preg only! No overlay. So that means the CF option will be very very costly.

        Someone better start convincing us to use wet lay just for the 'looks' if you want CF airboxes.

        Just a small update.

        Would like to thank everyone who has been sending PM's and emails supporting the kit and appreciating the detail.

        Also had a few guys who make SC kits themselves call us and appreciate the kit. Not sure if they want to be named so I will keep that to myself. Nice to see the tuners appreciating each others work!

        It's nice to see other tuners show appreciation rather than try to discredit/attack. That is how it should be.

        Wait until you see the final product all Teflon coated and with a brand new C38-91 on there.

        As mentioned before, our dyno dynamics numbers are not the same as dynojet numbers.

        And, as many have mentioned, it's not all about dyno numbers as we all know how they change with CF's.

        I will be going through dyno testing for SC'd cars later.

        The car is quick.... very very quick. It is also incredibly smooth and ultra responsive. This is where the Rotrex shows it's colours. Response.

        I was out doing some exhaust testing on our development car running non intercooled @ 5 PSi. I got badly caught out going on the gas very hard. I am used to driving high power SC cars and was not expecting the immediacy with this blower vs a slower revving gear driven one.

        Immediately toned down the throttle maps after that! Click here to enlarge

        having met these guys in person, i can only say they are pure gentlemen, and i for one am very much consdiering dropping my blown z4m and jumping into a supercharged m3 :-) evolve would 110% be the people i want to supercharge it, that said ESS have been nothing short of awesome in my experience with them, but i just LOVE evolves approach to the whole bmw scene...
