Talking B48 230i 1/4mile & 1/2mile times ... Impressed ! - 09-10-2018, 03:49 PM

Decided I needed to go to the track at least once this year and went out to one of the last 1/2mile of the season and could finally test out my Dragy in perfect conditions. I was pretty impressed (and others too) with the times my 230i with the B48 managed to get.

We went to the Sanair track and ambient temperature was around 18-22c during the day (64-72f).

It does not have the top-end power to smash the 1/2 mile (as well as the 135mph limiter) but I did manage to get faster time than a 335i xdrive and a M235i on the 1/4 mile.

Calculated with my dragy they did as follow :
N55 335i xDrive, Manual, Intake, JB4 Map 2, Did not launch the car : 14.02 @ 100.26mph (2.39 60ft). His highest trap speed for the day was 123.67mph on the 1/2 mile.
N55 M235i, Manual, Intake, JB4 Map 2, did a very mild launch : 13.36 @ 108.91mph (2.29 60ft). His highest trap speed for the day was 137.68mph on the 1/2 mile.

My only mods are JB4 (set to map 3 (+ 6psi) on the track) and the BMS billet intake (for the B48). Car was running roughly 98-100 octane and the tank was filled up prior to the day (Filled up with Petro-Canada 94 octane + Boostane octane booster).

My best times of the day were :

1/4 mile : 13.09 @ 103.68mph
1/2 mile : 20.85 @ 124.98mph
Consistant 60ft of 1.92 all day thanks to the xdrive.
Dragy screenshots attached

I’m hoping to smash into 12 seconds territory hopefully next season (12.99 would do) !

I'm also thinking. Is there any benefit of going with the EWG wires considering my setup ? And if I go with the EWG wires do I also need to get the Fuel Pressure sensor wire as well ? I'm not really planning on doing really more with the car (I only have 2 years left on it).

You had a bigger slope

Nice time ! Mean i'm hopeful that by removing the ''race day kit'' in the trunk which is about 30 pounds and dropping to 1/2 to 1/4 tank I should be able to do 12.9x in map 3. I'm a bit scared to touch map 6 since I'm not really confortable with the tuning process and which settings to verify (my knowledge in this field is limited).

I see the 0.09 difference seem to mostly be with your 60ft beeing exactly 0.09 quicker than mine which is the end result difference. You also trapped a slightly higher speed. I'm not sure how much boost total is with the Map 3 but I was under the impression it was around 19-21 psi. If you managed to be able to get 1 more psi i'm sure I could squeeze it too.

he difference seem to be between the 1/8mile and the 1000' mark where the extra psi or 2 should make a difference.

I assume you are Auto 8 speed as well ? Do you have the sport transmission (or reflash) ? How did you launch the car ?

Haha awesome performance for the 4 banger!

On EWG wires let's see the JB4 logs of say the 1/2 mile run and see how boost looks.

Yeah slightly bigger slope but also the car is heavier. And yes it’s 8 speed auto. Sport transmission coded and launch control used. Start from about 3000-3200 rpm. I’m going to put ******* ** and an intake soon. Will try to break into 12s at lower temperatures. 13.0 was at +23.
