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

        There are colder plugs available, some are just very expensive. AA does source colder plugs for their kit.

        Hmm, that is weird and not sure what it could be. With it being inconsistent like that it will be tough to pin down.

        I had a similar problem , in my case the problems had something to do with the o2 sensors after removing the cats, Ess did some adjustments and havent had any problems after that

        Thanks Pea, so the issue was in adjusting the tune? Don't see why Mikewads would not get those same adjustments.

        I had the problem with the Akra exhaust (with cats) and now with the Borla exhaust (no cats).
