• 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

      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:

      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.

        Some quick pictures as promised. These are not professional images. Just quickly taken outside of the car how it is. No cleaning of the engine bay. We use this car daily.

        The finish is anoldised silver on this one. Xylon coated in black comes at no extra charge.

        Just a few comments on testing.

        Hardware:

        The hardware used on the prototype is exactly what will be used on production with respect to design. As far as materials go we decided to test with weaker components. If the weaker components survive then we know components which are 10 x stronger will never have an issue.
        An example of this - boost runners through the front panel (the black looking intake pipes) are made of Nylon. Now this is nowhere near as strong as aluminium. Nylon is taking the boost spikes when we let off the throttle at the rpm limiter. We are using sub standard sealing methods on purpose in that area such as under sized O-Rings and cheap sealant. Still we have no boost leaks and the relatively weak Nylon parts are not blowing apart.
        The black wire run silicone hoses that go to and from the intercooler assembly have thinner than production wire in them. These are not blowing apart or deforming permanently. The production parts have a thicker wire guage. We therefore know they will be absolutely fine.
        The air intake pipe to the supercharger is also made from Nylon and due to the way it's constructed is a good 20 times weaker than a production plastic or composite part. Due to the fact that the intake pipe is connected to the supercharger which will move with the engine but the other end won't move as it's connected to the bumper, we needed to make sure it wouldn't break. The Nylon part is surviving. So we know a normal plastic or composite part will never break.
        Finally the CNC plenum and bracket. These are both made thinner than the production parts to see how they with stand stress and boost spikes. That was overkill as far as testing was concerned but you may aswell do it because it doesn't cost anything.

        So what we have essentially done is test the much weaker and inferior parts over the same time span as we would have tested the production parts. This way we know the production kit is bomb proof.

        The question some of you might have is did we blow anything up? Well.. yes we did. The Nylon supercharger parts blew themselves apart because we made them way too thin the first time around. From memory 2mm thick Nylon which was set in the wrong direction for strength. You could break these with your hands.

        Software Testing:

        This is something we are very comfortable with. Having worked on various other supercharger projects for other M power cars including the V10 S85 we have no issues. You can never stop improving small things but comes at no cost to our customers with updates when they are released.
        Many people will already know the dangers of high ignition timing. We aren't going there. We have seen the effects on exhaust gas temperatures and how they can sky rocket with high ignition once the engine is under load for extended periods of time. We have seen smooth consistent graphs and consistent performance under real world environments.
        Fuelling is set to give 0.80-0.82 lambda (11.76-12.0 AFR) for full load mid-high rpm.
        Part load when the blow off valves are open is naturally set to 1.00 lambda.
        Heavy part load mid-high rpm is set to 12.5-13 AFR with the lower being towards the higher rpm.
        These are the two major areas to be concerned about for end users.
        The rest is to maintain a smooth driving car with idles nicely and cold starts nicely.

        We can tell you that alot more work (which is not alot) has been needed on both the throttle opening maps and the pedal maps in normal, sport and sport plus modes.
        The responsiveness of the engine is way more than we expected! Any rpm, any gear.
        The engine is more powerful from as low as 1500rpm.
        When we say this kit will really please those who wanted some low end and midrange torque aswell as top end power, this kit will not disappoint.

        Other than that if you have any specific questions please go ahead and ask.

        Yes I know... you want to know the pricing!

        Not gonna lie, it did look pretty sweet. I was hoping that the hoses wouldn't get an aneurysm!

        The hoses will still flex with a thicker gauge wire. Will just be even stronger.

        @evolve

        the black xylon coating, is it glossy, semi gloss, or flat in color?

        I realize this is the least important issue, but just curious

        It's like a matt satin.

        Makes the whole thing look very expensive and OEM. I can see alot of people opting for this as the standard option.

        Other colours will be available at extra cost and with a very quick turn around time.

        Just deciding on how to deal with the bracket and supercharger rear output. The main supercharger housing is anodised already.

        Very true! At that rate, might as well port/polish the heads and add more aggressive cams...heck might as well stroke the motor too!
