Don't know how accurate the cobb ap is compared to a v-box but heres my result.

car is a 2008 335xi 6at running stg1+fmic v402 agg. mods are in sig and temp outside was 22 degrees with traction control off on stock rft 225/45/17 and stock 159 wheel. Test was done bb @ about 2500 rpm in DS mode.

If your running 3.9s 0-60mph I can only imagine my time with AR 3" cattless DP, Steet combo CAI & CP/Tail BOV and Cobb stage 2+ aggressive tune...

would 3.4-3.7 be pushing it?

I don't think so. Do you have a xi? I'm sure the awd is helping me because of the traction. Hey give it a try, but if you are rwd you may want to wait for better weather/warmer asphalt.

Sorry I totally missed that yours is a x-drive but did notice you have a 6mt, I believe its a little harder to launch because you have to abuse your transmission. I'm not saying that I'm not abusing mine ,but with 6mt its harder on the drivetrain.

So I'm deciding between an AWD and RWD.. Which is quicker? I will be taking my car to the track several times, so I'd hate to get an AWD and get outran by a RWD. What are the pros/cons?

As long as I know it has that potential I'm fine with not abuse the clutch to put it down lol. Maybe Berger will make a Lauch control feature one day

That would be cool. If any one could do it , it would probably be Burger.

I have a 2009 335i xdrive coupe.
with stage 1 aggressive map I managed a 0-60 time of 3.9 sec and 1/4 of 12.4 at 110 mph. recorded with vbox.

will be installing fmic and catless downpipes next week. will post times with stage 2 aggressive mapping soon.

Nice results. Yeah I was also impressed with the cobb when I just ran the stage 1 agg. What trans do you have 6 at or 6mt ?

Did some quick tests with my vbox the last few days:

Stock 0-60: 5.1 seconds
JB+ 100%: 4.5 seconds (93 octane)
JB+ 100%: 4.3 seconds (93 + 40% E85)

1/4 mile is 13.6 @ 103 stock and 13.0 @ 107.5 JB+, with the E85 I did 12.9 @ 108.5

I will be testing the Cobb maps soon, as well as the JB4 G5, and publishing test data from the vbox. All testing done in close temps on the same stretch of road (0% slope).

mykal335xi if I recall weren't you doing 3.xxx sec 0-60 with a jb4?

JB4 with nitrous I did a 2.9 0-60, without nitrous I was regularly at 3.5-3.7.

That was last summer and I had been de-modded until this last week. I doubt I'll go full tilt again because the downpipes are a PITA to get on and off, but I am going to be keeping the JB4 G5 and Cobb. I'll also be doing the inline fuel pump upgrade soon to run 50% E85 on a regular basis.

I see that you settled on the 335xi idea... good choice. Why'd you decide on the path less worn? (AWD 335)

Based on what I read in your signature, I'm interested in your plans for your car and hope to see similar aggression with modifying. There are some good set ups around here, welcome and may you become excessive with your modification addiction to this car as well

got 0 to 60 in 3.8 sec and 1/4 mile in 12.1.
have fmic and dp.
running cobb stage 2 fmic aggressive map, 93 octane pump gas.

0 to 100 time was 9.3 sec
0 to 60 ft was 1.7 sec

I did have stock fmic and stock dp in my trunk and had 3/4 full gas tank with this run.

I hit 3.9 but I have a feeling I could get better at it

[mykal335xi]

I compared the Cobb AP to Vbox the other day, 0-60 was close with the Cobb being a bit off (showing 4.4 vs vbox 4.5) and the 60 FT was reading a bit high. Pretty close though, I haven't tested the 1/4 ET or trap yet.

your time of 4.4 or 4.5 is slow for stage 1. that's the time I get with my 535xi. with my 335xi I used to get 4.0-4.1 on stage 1 aggressive cobb map.
maybe u need better 93 octane gas or better launch technique. also altitude does play a big role.

Thats not your v-box is it? I have that same g-timer and I don't think its accurate, theres to many variables like plugging in the weight and theirs rollout before the meter starts reading. I would use your cobb ap instead. I'm not saying its off by a lot but I think they tend to read on the lower side, the g-timer that is.

No it's exactly what I expected it to be, I never said I was all out launching it

My post earlier in this thread on Cobb stage 1 aggressive was 4.01.

my cobb ap actually reads 0.1-0.2 sec lower than g timer so I believe more in the g timer. with cobb 0 to 0 time is 3.7.

if I correct for 1ft roll out then the time will improve further.
there was an article in caranddriver comparing several of these devices and they were pretty close around 1/10th to 2/10th of secs, g-timer came a bit slower than gps measurements. so if gps is used then the time might be better by atleast 0.1 secs.

here is a link to comparison of several devices and seems g timer is 0.2 sec slower to vbox.

weight is needed by g timer not for time calculation but for hp calculations.
