    • DCT E90 M3 + supercharger = Easy 10 second car - ESS-Tuning VT2-650 M3 S65 V8 supercharger kit runs 10.89@127.8

      Some people still seem to doubt how potent the E9X M3 is with a little forced air. What you see here is an ESS-Tuning VT2-650 supercharged E90 M3 breaking into the 10 second 1/4 mile range with no drama. This is a four door car that can be daily driven but provide exceptional performance when necessary. This is not even the strongest supercharger option out there for the E9X M3's but what the run shows is that 10 second performance from an M3 with a supercharger is easily within reason.

      Expect to see more E9X M3's breaking into the 10's which is hardly considered a rare or difficult feat for the platform any longer.

        10s is impressive on any street car in my opinion. This being a 4 door car wtih "mild" modifications makes it even more impressive.

        Well it pointed out the ESS setup versus the Gintani setup takes a different approach. Gintani wanted less tress on the crank for roadcourse duty.

        Well, our car speaks for itself. Shocking that the Blackstone analysis came back on our shop car as just 'slightly elevated' for aluminum, iron and lead content. I was expecting a disaster. Eventually we will swap the bearings...

        I've been around hot rod cars for my whole life (and most of my career) and the bolt on SC E9X cars are super impressive to me.

        When you modify and beat on a car it will break, just a matter of when - it seems like some folks in the BMW community are less willing to accept that fact. I had a guy with a 650 kit and blown engine try to argue with me a few weeks back about how BMW built a lemon etc etc and that it should have *never* failed at 50k miles...

        There you guys go.

        How you maintain and drive the car matters as well. The bearing problem is overblown but obviously they will wear more with a blower. If you're thrashing it on the road course daily, you might want to call VAC.

        Maybe try and start off local before going for the ring Click here to enlarge Buttonwillow CW13, your car could easily set the record and beat FXMD's lap time of 1:40 Click here to enlarge

        I think I'll do whatever I want with my car. But you feel free to read up as much as you like.

        Not difficult at all. Been done Click here to enlarge

        We abuse and go way too long on oil changes with this car. Hell, we have yet to change the trans oil! (DO NOT RECOMMEND ANY OF THIS OBVIOUSLY)

        I will say there should be some level of concern when it comes to S65 rod bearings. Not S54 level, nothing that should force you to sell the car out of fear, but it's absolutely something of concern.

        Exactly. Some people just blow things out of proportion Click here to enlarge

        i wouldnt count weight reduction, race tunes and methanol a simple bolt on modification. VAC is the only one so far that took the car out in normal trim (yes, maybe seats out, but it IS a RACE car) and did 10s.... for now

        and ESS does have the title of worlds fastest E9x.. also, for now..

        Edit- @Mike@VAC just read all your comments lol, yes, its the owners that do it, not the kit Click here to enlarge

        I honestly think a 93 octane, VF620 or ESS625 (with matching pulley and tune, lol) on a stock weight DCT E9X can run .50s with ET Streets.

        If we get the car back out again, that will be the goal. Prob is, we have to worry about getting booted from the track...

        I definitely agree.

        Not just boost, less - no timing drops also if its tuned correctly

        Timing drops could just be an N54 issue

        Whip out a BT tool and log your timing across multiple shifts. We'll know very quickly what's up on the S65. I'm surprised people do have very little interest in logging and understanding what their tune is actually doing on the S65 platform. I know you've done some datalogs when you were testing meth but I think a lot more should be happening out there.

        Uniter and defiv have my BT tool. to test the direct port stuff.
        i do use the BMW logger s/w, but its only 1 cyl.. i dont know if i have multiple gear WOT shifts in any logs though

        How is your run to run consistency on the timing front though? Do you know what your tune is targeting vs what its hitting based on boost vs. rpm? You can easily spot timing corrections if multiple runs are yielding different timing curves especially with traction control off

        S65 timing is a bit more dynamic, youd have to talk to the Evolve guys about that. They posted the stock targets a few places, i dont think anyone posts the tuned/boost S65 stuff publicly, so ill have to defer to them, but i have yet to see corrections or deviations - at least anything i can spot
