From Jan 2009
Did some baseline tests on the new 335I sedan. As the car is still pretty new (148 miles), it is still fairly tight, and the numbers are not that great, but still in the ball-park. In my past experience the cars seem to perform quite a bit better once they have about 7000 miles on them, with traps a good 1-1.5mph better than when they are brand new. The car is totally stock, 91 octane, with no optimization done at all for good ¼ mile Ets. Stock RFTs set at 36psi.

The totally stock runs: Near sea level, 52F. 91 Octane Shell. 01/01/08

Run#1 13.5 @ 103.1mph (2.0 sec 60’ time)

Run #2 13.5 @ 103.6 mph. (2.0 sec 60’ time.)
0-60mph: 4.9 seconds, 0-100mph: 12.5 seconds

Run#3 13.5 @ 103.6mph (2.0 sec 60’ time) Identical Times!
0-60 mph: 4.9 seconds 0-100 mph: 12.5 seconds.

AFTER INSTALLING JB+. 50F, 91 Octane Shell. Same day, same test section.


Run#1 13.2 @ 108.1 mph (2.1 sec 60’ time). More wheelspin!
0-60mph 4.7 seconds, 0-100mph: 11.4 seconds.

Run#2 13.1 @ 108.1 mph (2.0 sec 60’ time).
0-60 mph: 4.6 seconds, 0-100 mph: 11.2 seconds. (over a second quicker than stock)

Run#3 13.1 @ 108.0 mph (2.0 sec 60’ time)
0-60 mph: 4.6 seconds, 0-100 mph: 11.2 seconds.

So with better traction, (lower tire pressure or after market tires), and more adaptation, this would be capable of hitting the 12’s without a doubt. And once the car has a few more miles on it, that alone might do it.

Edit: 08/16/09 (at 2800 miles)
60F, Shell 91 Octane, Besides JB+, Bone Stock including stock 18” Run Flats

Run#1 13.0 @ 109.6mph (2.0 sec 60’ time)
0-60mph: 4.5 seconds, 0-100 mph: 10.8 seconds

Run#2 12.9 @ 109.6 mph (2.0 sec 60’ time)
0-60mph: 4.5 seconds, 0-100 mph: 10.8 seconds

Run#3 13.1 @ 109.7 mph (2.1 sec 60’ time) bad launch
0-60mph: 4.6 seconds, 0-100 mph: 11.0 seconds

The car is running noticeably quicker now, and certainly capable of running in the 12's with just JB+, on 91 octane. You can see on average my traps are now about 1.5mph faster, so about a 15hp improvement. You can also see the 0-100 times dipping into the 10 second range now. And these latest tests were in warmer temps also.

Do you have an oil cooler?

What setting did you put the JB+ at ? Half, 3/4 or Max?

My guess is 100%...

Not sure though...

Mine is one of the first non-adustable units, But its at about 75% for comparison sakes , and on 91 octane. Haven't set it at 100% yet. Unless you live in 3000FT+, elevations, I don't think you would have any problem with codes at 75%. Car runs butter smooth with a nice strong torque curve.
