Hello guys, i need some of your opinions before doing this, i have a friend who has 2008 BMW 550i
We had an argument so he wants to race with me next week and he has announced it all over facebook promising everyone how he is gonna smoke my car. I have no doubts myself just curious what you guys think about this?
Any suggestions before i go to race?
Thanks!

But my 2012 550i Dinan Stage 2 has been doing 4.1-4.2 seconds to 60 on the dragstrip.

The car is designed for 91.
Anything lower will slow you down, anything higher is useless.
Your imagination.
Power output is identical in both cases.
But ECT-Power will shift at a lower RPM in a 0-to-some-speed floor the gas race... which is the opposite of what you want.
Normal mode for the quickest 0-60 and 1/4 mile times.
No.
In fact it mentions at least 2 or 3 times in the owners manual to never tow with an ISx50.
Power mode is useful in part-throttle and on/off throttle and brake type driving. (ie weaving through traffic type stuff) not drag racing.
Here's what ECT-Power actually does, straight from Lexus:

so much fail in this thread. just go to the "track" line up next to him, take off VSC TRAC and DONT brake launch, you wont get it down right.

I know your a god when it comes to these cars but ETC POWER (under FULL pedal depression) actually makes your gear last longer not shorter. Still I would leave it on D and not touch anything else but the TRAC/VSC off button....
and if you cant seem to beat him out of the whole, ask him to do a 20 mph race... use the paddle shifters (1st gear) to hold you at a contanst high rpm, count to 3 and drop the hammer.

yup i will try that too thanks!This is correct. Only thing you want to do to prepare for the race is to turn off traction control. Leave everything else the same(shifter in D, ECT normal). You should lower your tire pressure to around 30psi in the rear to improve traction. Brake torquing before the start to around 2k to 2.5k rpm's will give you the best launch. You can safely brake torque for 3 secs without damaging the transmission but I wouldn't do it any longer than that.
Good luck and let us know how it turns out!

Ok here is the question about breaking torque should i have to keep my foot on break and same time keep it on 2.5 rpm.? Is that how it works?
Sorry never did it before)). I raced before but not with automatic cars.
so it's better to take out all engine covers?
I will try mybest to make a video of it but i don't want to taking myself, i'll try to take one of my friends to take some videos.
thanks a lot for advices!!!

Don't mess with the front tire pressure, 35-38 psi is fine. And the engine covers don't weigh hardly anything so, personally, I wouldn't bother. You could take out the back seat though, it comes out easy with just a good tug on the front lower portion along with anything in the trunk, center console, and glove box. No passengers unless he has a passenger as well.
