New personal best - 15.38 qtr mile tonight in the 525i

[DanDombrowski]

Went out in my E34 to Moroso tonight to test out the new configuration (new wheels, tires, shocks, 3.73 LSD).

My previous best was a 15.68 or so. I can't find the timeslip, so I don't know what my 60' and RTs were (on my previous best). Actually, I remember posting them a long time ago, maybe I can search them....

Anyway, my new best on my first run was a 15.38 @89.9 MPH (my trap speed didn't go up at all since my best time, odd). I had a 2.3 60' and a .198 RT.

The odd part was that after that first run, my runs got consistantly worse throughout the night - 15.47, 15.6, and 2 15.8s. My 60' times between runs weren't more than a second or two, so it was a power/shift difference, not just the launch. I'm thinking that I wasn't opening the hood enough to allow the intake to cool.

My best RT of the night was a .141 against an Acura TSX which I embarassed (15.8 vs 16.9)

Anyways, thats about it. Next time I'll be running my bottlecap wheels on the front to reduce weight and drag, hope I can do better.

I thought trap speed was a measure of total power, what was your old differential ratio?

[DanDombrowski]

Trap speed is how fast you cross the finish line. The old diff was a 3.23 open.
