    • RennTech tuned BMW 335is DCT versus a stock CTS-V Coupe - Good example of hot weather / high Density Altitude effect on times

      The CTS-V with its 6.2 liter supercharged LSA V8 is a very potent car. In a drag race it is expected to run low 12's but what happens in the video below versus a Renntech tuned DCT 335is goes to show how big of an effect conditions can have especially on a positive displacement supercharged car generating a lot of heat such as the CTS-V. This run took place at PBIR (Palm Beach International Raceway) in 85 degree weather and 1800+ Density Altitude.

      The 335 manages a 12.4@113.86 to the CTS-V's 12.8@112.41. The CTS-V and 335 are both capable of more but in hot weather that is what they run. Many people make the mistake of taking a fast time (such as a Z06 running a 10 at MIR in the winter) and thinking the car is always capable of it. The weather has a huge effect on performance.

        BuraQ have you added a better IC for your car? I believe if u havent and would so , diffinetely your times would be better than the V, dont get me wrong I love (the Vs)them but they are very rare here in Puerto Rico. I think Ive only seen a couple here, arent they running the same engine the Vette is?
        I am using the Dinan FMIC which has a 93% volume increase over the stock FMIC. The Dinan FMIC is a modified Spearco untilizing their W.A.V.E. Technology bar and plate cores.

        The same event day my best ET was 12.2 in that heat. I was even able to trap 115 which was all about finding where to shift in those weather conditions.

        Here is another video from the same day running against a JB4 Map 7 E90 / DCI /DPs/E85 mix, first timer on track. On this day I was running on stock DPs



        I think I was the only BMW there that didnt get a limp mode from that heat. Mostly everyone I spoke to had limp mode issues

        But with the M4 coming out with more HP and torque stock, are you so sure you want an N54?

        The concern about the M4 is it has a modified N55 motor. Regardless of the multiple turbos it will have, limitation is going to be the concern.

        I have thought hard about getting an M4 but is it worth it when all I may need is a turbo upgrade on the 335iS. Even so a stock M4 will still catch hell with my setup.
