Talking Ran my 335I e92 Tonight 1/4(1320)

I Just ran my e92 2010 335i tonight at the drag strip (1/4 mile).
Stock 19" style 230 wheels with oe RFT 245 in the front and 255 rear.
My only performance mod I have is the jb+ at 100%.
Steptronic Transmission
93 Octane (little over 1/4 tank filled)
Track was dry with temperature in mid 70 degrees Fahrenheit.
All my runs are on the right side of the ET slips.
BTW this was the first time I did drag racing lol, I think I did fairly well (I even beat my friends e60 m5, he said he couldnt hook his power down and he has the 6 spd manual.)
I feel that I can get into the 12's because the track wasn't really that great and the evo/sti guys were running high 13s to mid 14s.

All my runs are in order from 1st to last.

Good runs. I'm assuming you were doing the 13.1-13.4

Are you RWD or AWD ?

That is amazing. I have not been to the track since I got my e92, although I just got it a week ago. I have however use to go to the drag strip in my WRX. The best times I got with that was a 13.6, so that is amazing that a stock 335i can hit low 13's. I'm excited. I am new to the Bimmer scene and was wondering if youcan give me some tips on launching the steptronics. On the WRX, all I had to do was feather the clutch and felt the grip and floor it. Seems simple enough, or at least easier than the steptronics. I was reading how to launch and everyone has there own way of launching the steptronic. I would like to see how you did it, if you would like give me steps, pointers, or anything that can help me.

Thanks.

did you do the bypass vac line thing being at 100% with the jb? Ive been at 50 for years and actually just bumped it up to 55 about an hour ago (haha adventurous). The best time i've seen with a jb+ was 12.7 but the guy had drag radials on.

I don't get why you guys get the JB+ over the JB4, it's really not hard to install...that should get you into the 12's

The above guy's 335i isn't stock. He has a JB+, a tune. Some other tunes I have heard of and going to buy one soon are Vishnu Procede, Cobb, JB4...prob going with Vishnu b/c it can control meth injection

He's not stock--just very close to it. He's running a JB+, which is a very mild tune.

OP: Practice your reaction times--you could shave a tenth off right there.

Looks good - first run is weird though, ET looks around right at 13.3, but the MPH is way to low for a 13 second run at 87 mph and the guy you ran in the 12 second Camaro only did a trap of 94 mph - looks like something was wrong with the equip measuring speed. The rest all look right in line for your mods, last one is nice a 106mph trap at 13.2.

it's mild by adding 100hp at 100%? although its only a stage 2 tune, it is adjustable and still makes the car very fast. reaction time also counts obviously.

and the jb4 is worlds better just a more invasive tune changing a whole lot more in the engine (timing, fuel mix etc) than just tricking the turbos into spooling to higher boost as the jb+ does.

Reaction times has no effect on ET's.

Reaction time has absolutely ZERO to do with his times. He could have a 4 minute reaction time and still run a 13.1

Those are some pretty good 60ft times. I just went today and my best 60ft was 2.16s - I felt like I was fighting for traction on all of them and I'm completely stock, I can't even imagine a JB+ at 100%. Were you running with DSC totally off, or just DTC on?

Yeah the 1st run their equipment was messed up. I raced in all my passes with dtc on (the option with slight traction control; I was also brake boosting launching around 1.5k-2.5k rpms. Do my runs seem right for my car's setup?

Thanks - I did all my runs with everything full off and seemed to have quite a bit of wheel spin - my best run was when I did a good job of modulating my throttle to limit the wheels spin. Perhaps I'll try the DTC on next time.

And I'm not sure if those seem good for your car setup - I'm still stock and at high altitude. My best run today was a 14.1 @ 99.5 at a DA of 7,400 ft. Corrected that is ~ a 13.5s @ 103 which is about what I'd expect for a stock 2010 steptronic at sea level. 13.1s seems pretty good to me for just a JB+, but I'm not an expert like some of the other folks on here.

OP- talk to Terry about upgrading to a JB4. I'm not trying to assume that youre unsatisfied with your JB+...
Its an easy install and you'll understand exactly why people recommend that you do this once you do it and go WOT for the first time. Stage 3 tune FTW...

Reason being I got the JB+ was I got it for cheap, I'll being upgrading to the jb4 in the near future. I'm already tired of the power the jb+ gives me lol. The M5 actually ran a 12.66 on a mustang dyno yesterday morning lol, if he had better tires on the track he could for sure run into the 12s.

I am thinking about getting the JB4. I heard it was very nice upgrade. I still have to practice launching with the steptronic. Traction on/off, holding the brake while halfway gassing it, etc. Thanks guys. I didn't see that the op had JB+.
