Our clients car a 2011 750Li x drive which has a 6 speed automatic transmission, with 21″ rims ran an 11.50 @ 121 at local drag strip. The cars modifications list as follows:
E40 gas on stock fuel system
Stage 3 Tune
JB4 with bluetooth for logging and few extra LBS of boost with 3.5 T map support
V4 Carbon Fiber Intake
This is the best looking intake for n63, the sound is amazing, you can feel Improved low end response from the car also.
Great power gain, car running 11.7 1/4 mile, my next step will be moving up to stage 3.
Best N63 tune out there, doing 8.1 60-130 with meth and Stage 3. Best of all is the customer service, Sergey always replies and helps with my car past the tune.
If you- want to have a very loud woooosh blow off sound dual port is the way to go, easiest and fastest way to install is by pulling off the turbos.
So besides the obvious, keeping my oil temps down around 5-10 degrees, the most noticeable thing after installing this oil cooler valve is not having to add a quart of oil to my engine every 2-3 weeks like I did before installing it ! Just in the extra quarts of oil that I don't have to buy anymore , it paid for itself in no time ...
