    • 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.

        i deff feel the guys at Evolve are awesome just talking with them.

        It looks nothing like the ESS plenum. Please see below.

        That looks perfect actually. looks like it combines the functionality of the VF mani, combined with the good looks of the AA kit, to be its on unique and very appealing manifold

        Thanks guys!

        Wait till you see it the flesh... CNC machined aluminium in dark grey teflon coating.

        The weight is also very low.

        Well done Sal/the Evolve team.

        I understand the advantages of correct sizing a charger and by that I mean not pushing it to the max. Not only are you reducing mechanical stress but dramatically reduce thermal loads; Sal has already stated how sensitive the S65 is to temps.

        Also using a FMIC is the way to go, loads more efficient than a water to air charge cooler. Really happy to see this and hope this is how Sal and the team go about the S85!!

        Evolve will soon be a one stop shop for the E90/E93 or the E60's.

        Just release this kit already so you can get on with the S85 SC kit...

        I wouldn't blow any of these engines with out charge-cooling, just asking for trouble. Sal stick to your beliefs! Sell a few less kit and add the reliability. One blown engine will make all the others jump all over you.

        A great update! I love the look of the manifold. I can't wait to see photos of the first one you produce.

        Hi Jay,

        you mean intercooling Click here to enlarge

        I know what your getting at here and it's to do with us releasing a non intercooled kit.

        Our non intercooled version will have a maximum of 4.5 PSI. Now, what we did was to wait for below freezing conditions when we tested this as temperature at the filter (which is ambient in this setup) has a profound effect on boost. As the inlet temperatures to the blower reduce, boost rises.

        So, under below freezing conditions we achieved 5 PSi. So, above this you will be hard pressed to achieve this and be around 4.5 PSi.

        At this boost level you are producing very little heat and as long as we can maintain low inlet temps and low EGT's it's not such a bad idea.

        However, the problem is that people can buy Rotrex pulleys direct and swap them out and increase the boost level themselves. This then does pose a problem. Running 6 PSi and above non intercooled is simply not a good idea. You should see where the temperatures inside the plenum go!

        yeah ive ALWAYS prefured intercooled setups, but low pressure non cooled kit isnt a bad idea....

        now Re the intercooler im so glad you guys choose a FMIC.... much better recovery times, im really glad you went this route........ The pipework takes time to get right but once you get a really good fmic setup i think its pretty unbeatable and far less more to go wrong.... simple really is better imo.... Can you talk about the bypass valves your using in this setup sal?? Also another point Re the intercooler is we can run meth as charge cooler :-) Not a fan of using it as a fuel but as a charger cooler 49% meth - 51% water it really makes a difference, some of us blown z4m guys run them and were gaining 40rwhp in the powerband.... Whats your feeling on using meth in this way??
