    • Bolt on tuned E89 Z4 DCT vs. E82 1M, 335, Shelby GT500, E60 M5, C6 RS6 sedan, and F10 M5

      This BMW E89 Z4 35i is a bolt on N54 model tuned by BQ Tuning. It features a Cobb Protune, Afe filters, MMP inlets, MMP outlets, Wagner Evo 2 intercooler, VRSF catless downpipes, 200 cell sport cats, and was on a mix of E45.


      Apparently the car suffered a bit of a boost leak but it is hard to tell based on the performance.

      The first race features some N54 on N54 action as the Z4 runs a 1M. It is not much a contest. The DCT plays a big role but the difference between the cars is large.

      Race 2 is against a 335 wagon. Also easily dispatched.

      Up next is a Shelby GT500 Mustang. This is the first good run of the bunch as they go neck and neck with the Mustang opening a slight lead early on. The Z4 closes the gap and edges. Impressive!

      A JB4 tuned M135i runs next. It hangs in there for a bit but ultimately is pulled up top.

      An E60 M5 with unknown mods tries its luck next. The S85 V10 is known for its top end pull but the Z4 dispatches it easily. A great run for context.

      An Audi RS6 sedan tries its luck next. This is the C6 generation RS6 with a twin turbo V10 motor. It is tuned by MTM and pulls as it should but the Z4 actually does an incredible job against it. Maybe time to upgrade those N54 turbos?

      The final run is against an F10 M5. It looks stock based on the result as the Z4 pulls it.

      This E89 is running very well. Impressive stock turbo N54 performance.

        That Z4 runs really well. With upgrade turbos it would be a monster. I was at the same race in my Pure Stage 2 powered N54 E92 335i 6MT. I also raced a lot of the same cars. Here's a video of me racing the Shelby GT500 just for fun/comparison.

        You definitely look faster than the Z4. Did you race it?

        No not this time around, but the next event is in 4 weeks so maybe I'll try there. I spoke to the owner of the Z4 though, and he is a really cool guy and his Z4 is absolutely beautiful

        By the looks of it from these two cars racing the GT500, the Z4 will get walked by well over a bus length.

        This cars are very quick, maybe power:weight ratio but I remember working on one a few months back, this thing was making crazy power for not having mods, I can't even imagine this one on E mix and a solid tune! Also pretty important to point out -- Cobb AP protuned!! Great work

        Wonder how much boost this N54 is running? Has to be close to 25psi

        Pretty sure that's a NA V10. Good run none the less

        i didnt think stock turbo n54 is faster than a healthy f10 m5 till 160 miles even if its on e89 stock turbo r worthless after 21 psi

        big respect to the z4 owner

        Thanks man. I am not sure, I was supposed to have it dynoed yesterday, but a belt in the dyno broke, so I will have it dynoed next Thursday instead. I am expecting around 600 whp. It's boosting around 25-27 psi ro redline

        nope, c5 rs6 is v8 twin turbo and C6 rs6 is v10 twin turbo and the new C7 Rs6 has the same 4.0 twin turbo as RS7

        You should be closer to 630-650whp at those boost levels. I made 601 at 23psi.

        Cool, you may well be right, I'm just very conservative in my estimate. But it does pull really hard, especially near the rev limiter

        Incorrect. You're thinking of the S6.

        Nowhere near it

        Here is a log with his boost leak, same exact map he ran on the event

        http://datazap.me/u/sjobusen/bqe45-a...10-11-14-19-20

        Here is the log after he fixed his boost leak

        http://datazap.me/u/sjobusen/bqe45-a...-20&zoom=8-196

        Average boost is 19 PSI barely peaking 20 psi

        Hes gonna be moving over to MHD so I will be able to hold boost longer in the 20-21 psi range tapering to about 18-19 psi

        The Z4 also has better intake airflow compared to the other N54 cars.

        Awesome, it took down some heavy hitters

        Really good tune. The car ran strong even with the boost leak.

        Nicely done D. He had some good take downs.
