Our 630HP Supercharged E39 M5 gets a Wavetrac Differential

  • If you follow us on social media you'll know we recently bought an E39 M5. This is no regular E39 M5 however, and whilst it is supercharged, it's so much more than that. We'll explain more in a future video.
    In this video we pull the rear diff out of the car and head to our friends at Wavetrac Europe to give the car a better chance at putting all its power down with a Wavetrac differential. We find out it already had an ATB fitted so we also take a look at how a Wavetrac is an upgrade from a conventional ATB.
    Wavetrac Differential for E39 M5:

    Just completed wavetrac install in my supercharged 2000 M5 and I am totally impressed. Before in my car when I would launch off the line it would always kick the back end to the right side but now with the wavetrac it just goes straight. Another huge plus is the wavetrac diff is exactly 5.2 lbs lighter than the stock M5 diff . Taking 5 lbs of rotating mass out of the driveline is beneficial in so many ways.

    It wasnt a stock diff in it as they pointed out it was an aftermarket diff but not a wave track. BMW LSD riffs are clutch type riffs that work much different than the one they pulled out which was not a clutch type and was close to the wave trac design already but without the wave trac part they showed that creates a better pre load than the other after market. Although he kept referring to it as OEM. I'd love to have one in my E46 M3 but cash is not there for it yet.

    • @sarcastixx74
      @sarcastixx74 4 года назад

      The wavetrac diff works out cheaper than the quaiffe ATB diff, they do need the output flanges to match which adds on another couple of hundered quid or so, depending on where you get it from. I'm in the same situation, got stock diff with 140k on it. No issues with it yet but I always hope it goes bad so I have the excuse to smash my piggy bank and go for the wavetrac! Total price is around £1500 for a full wavetrac setup depending where you buy from as opposed to around £1700 for the quaiffe. Not sure if a bearing rebuild kit is required for the wavetrac but I know it is definitely needed for the quaiffe which adds another £300 or so. I reckon a budget of around £2.5k max would be enough for a fully fitted swap (inc bearings if needed).

      @Steven Ross-watt Yes of course, the stock e39m5 diff unit is a ZF clutch plated lsd with 25% lock and 110-130Nm preload. I hardly doubt there would be any noticeable difference in driving experience between a quaife unit and a wavetrac unit, considering the fact they are both ATB type and should work the same way in situations when both rear wheels have any traction ...

    • @fabianyee
      @fabianyee 4 года назад +2

      As explained in the video, the car came fitted with an ADB torsen diff carrier and not the standard BMW clutch LSD.. Torsen diff behaved differently from clutch type LSD. It can go between 0-100% lock. And zero maintenance. The ADB diff has no pre load so when 1 side of the wheel is completely off the road, it becomes an open diff.. the wavetrac designed with a ramp to counter this... watch the explanation on the video again.

    • @EvolveAutomotive
      @EvolveAutomotive  4 года назад

      We have another Wavetrac video on our F56 Cooper S if you haven’t seen it which also explains how the Diff works.
      Having seen the internals of the diff, I wouldn’t consider any other type of ATB diff. This is like buying the latest iPhone compared to the original iPhone. There’s no downsides it’s just a newer technology for better performance.

    • @RickySlickk
      @RickySlickk 4 года назад

      Evolve Automotive yeaa, learning how the wavetrac doesn’t suffer from losing traction during zero axle-load conditions is impressive despite being the helical type. I had an e92 m3 and really considered changing the diff but I didn’t much at the time. Would you recommend going up to the 4.10 ratio with the wavetrac in the e92 or would you leave the ratio unchanged?

    • @EvolveAutomotive
      @EvolveAutomotive  4 года назад +1

      Ratio is down to personal preference. Haven’t personally experienced one with a different ratio in but the theory says you want to make your gears as short as possible. No sense being geared to 200mph if you’re only ever going to do 150 for example. Obviously there is a loss of fuel efficiency as you’ll be doing higher RPM at cruising speed. But you’ll gain acceleration which can make a car feel like it has gained raw horsepower.

    Wavetack diff aren't that great all those gears unlike a clutch type. Vicious/cone style are crap look at all the oem cars with non clutch type units they fail or are crap for any sort of performance. Plus a BMW has a clutch type all ready so why would you change it ?!! . Should of got a OS giken or other clutch style or brand that sells them .
