Close

    • 10 second barrier broken! Mikewads runs 10.8 1/4 mile at the drag strip in his supercharged M3, the S65 beats the N54 and S54 to 10 seconds.

      Went to the dragstrip yesterday determined to get into the 10s. It was a Buick Grand National race that allowed test and tune between rounds. I surprised many black Buicks when a lonely white BMW blazed down the track. Car was at full weight, 96 octane (I added 2.5 gallons of VP100 to the 93 already in the car), and no burnouts (went around the water box every run).

      On the first run I went 11.53 @ 126.7 mph on just supercharger (with a 2.01 60' time). The in car video below shows that particular run. Enjoy!

      Next run I added a 100 shot of nitrous in second gear which gave me a 11.07 @ 131 mph. So close, but not a 10...

      On the final run I decided to hit the nitrous as soon as I went to full throttle in 1st gear. It felt like a Toyota with a stuck throttle hit me in the rear when the nitrous came on, but the beefy 305/35R18 Mickey Thompsons held their ground.
      The results 10.87 @ 131 mph

        No, in the link he clearly states that the new 60-130 was with nitrous.

        Exactly, it has nothing to do with the owners. The E46 is weak for drag racing, well documented, and it needs tremendous reinforcements in several key areas.

        SSP has been telling me how surprised they are regarding the strength of the E92 M3 rear end. It would seem BMW really beefed it up after the E46.

        Congratulations, that is a great ET and trap!!! Those SC M3's are badass! But why didn't you use the water box??? I'm a little confused why you wouldn't maximize your launch if you are going for an ET record.
        Yes, for this car it's a good 60', but what would I know I have little experience launching this car. Click here to enlarge

        They have been in the 9's but definitely not on the stock rear end. The E36 guys have it figured out though as to what parts to change, the E46 group doesn't drag race in the same manner.

        It's only fantastic because of the extra TQ the NO2 provided. I launched the car the same way every time (explained further down). See how the NO2 increased the 60' each time:

        60' times:
        No NO2: 2.01
        NO2 in 2nd gear: 1.96
        NO2 in 1st gear: 1.83

        Now if I launched the car hard it would go a 1.7x in the 60', but then my DCT clutches would probably need replacing. I'm trying to avoid that.

        Nitrous really helps, from mid 11's into the 10's, incredible.

        What was your launch technique?
        Thanks man! I knew you would be ecstatic over this. My launch technique is rather boring, but this is what I did:
        Get the car moving and then quickly go to WOT.

        I still can't get over how great this is. I'm kind of pumped up now regarding M3 performance and optimistic.
        Here is my slip from the video (Supercharger only). I was running my friends X5M with ESS tune. Pretty good for a 5600 lb. SUV. (1.88 60' time)!

        Thanks! I had a Grand National fan club going on! LOL

        He probably avoided the box due to issues with the DCT overheating after a solid burnout. I have had that problem when SC'd, but not when NA.
        Correct. Overheating and very hard on the clutches.

        I would rather have a manual transmission with aftermarket clutch for drag racing. Then I could do a great burnout and get 1.7x 60' times all day long, but I still prefer the DCT because it is so impressive from a roll on the street which is where I spend most of my time.

        Did you try burning out at all though? Have you experienced an overheat yet?

        Upgraded clutch discs from SSP exist and a cooling system is in the works, you should be able to do this if you want to. Not to mention be more consistent and faster than a manual Click here to enlarge

        Thanks! I'm surprised the ESS tune did not have a greater impact on the X5 M. We have a user with a tuned X6 50i running 12.8 @ 107 with a tune in his car. That time is about what it should do stock.

        I have another question Click here to enlarge You said you shut your nitrous down at 8000 rpm, right? So does that mean you shift at 8k or do you still rev it out the limiter? If so, don't you abruptly lose power?

        I have in the past. Sometimes it would overheat. It's just too hard on the stock tranny in my opinon.
        I don't won't to remove the tranny unless I have too. At least I have an aftermarket option now though.
        Stock on the X5M according to Edmund's Inside Line is 12.8 @ 108, so it picked up 3 tenths and couple MPH.

        The dyno operator shut it down early when I was on the dyno earlier this year, I told him not to hit the rev limiter that day. When I actually run the car with nitrous I shift at redline (usually when I see the first red shift light). However, our throttle bodies close a little bit during the shift, so that would disengage my nitrous system. I have not actually felt the nitrous cut off during that time though, its probably because the car is shifting at the exact same time and the throttle bodies only close a little for 1/4 of a second.

        I just got off the phone with SSP and the trans cooler is coming along well. You may be interested in it simply to preserve your stock clutch discs so you don't have to remove it.

        Yep, it depends who you read. Without a baseline we are speculating but I have seen up to mid 12's @ 110. I guess I was just expecting low 12's or high 11's at 115+ but that will come with time.

        Ok, so you are maintaining power to redline with the nitrous essentially even though it cuts out at 8k?

        The nitrous does not go off at 8K. It is controlled by a WOT switch next to the throttle bodies.

        When the throttle bodies open 100% the nitrous is activated. If the close any its deactivated.

        I see, I misunderstood, in a previous thread you made on the nitrous you said 8k was the cut off.

        Gotcha, that makes sense and means you have it until you switch gears essentially, very cool.
