New n54 trap record

I was able to attend a track day at Famoso raceway today. The scheduled start time was 9am but that got pushed back due to a rain delay. It was around noon before we got to do any runs.

I decided to race our 135i with the new MOTIV 750 kit today and just go for traps. To that end I ran on the normal 245/45/17 555Rs and just launched the car in 2nd gear with boost capped at 12-15psi.

Logs on the dyno looked great fueling wise but as soon as I started doing runs at 26psi at the track, a problem became apparent. The low pressure pump was not keeping up. So I wasn't able to do any high boost runs as I had originally planned. As the day went on fuel pressure got worse and worse.

Still, managed a respectable 136.4mph trap speed. I've attached the log of the run so you can see how bad the fuel situation was. It actually did a map4 switched right at the cones so I may have gone a bit faster had the pressure hung on a bit longer. After this run, I decided to pack it up and head home. Only to my surprise, after parking the car, it wouldn't start. An hour of diagnostics later I figured out both my inline 255 & my fuel pump controller shorted out. Luckily I was able to hotwire the primary pump with some spare wire to get the car home under its own power. I've got a Fuel-It Stage3 bucket in the garage that will go in and I'll have to probably order another controller.

Anyway next time, whenever that is, I should be able to run enough boost to hit 140mph. I figure it will take 32psi. Then I'll strap on the Hoosier slicks and start working on the launches.
