163.674 mph at El Mirage for Casper
The fastest diesel truck ever at El Mirage Dry Lake time trials is now EFILive tuned. The existing record speed for a diesel truck was 161mph, and I bumped it to 163mph on Sunday.
First run in the AM was a rookie licensing pass, and it went smooth. Peak GPS speed was 175, so I had to give it up to get under the 150 cap.
Second run was at the end of the day, and the starter warned me the track was tore up, and to stay left. El Mirage is a 1.3 mile dirt dragstrip. Not alot of traction, not as much as Bonneville even.
I got rolling up to 150 then problems. Tires started to spin, slowing me down. So I babied it, spinning all the way through the beams at 163mph. When the aero resistance starts to approach the traction force, it's like driving in the snow is the best I can describe it. You can accelerate, but you must be careful. Never did a finish line look so good. Maybe I should have just cruised, but the killer instinct kinda overpowers everything else.

We have to work on traction if we expect to go faster. I ran 2wd, and did not use ballast. Mistake on both accounts. The 4x4 thing is being hashed out with the rules committee for 2009, but for this year, it's 2wd.
Could not look at the gauges, and didn't have time for datalogging. I was just going to drive.
We need to get the paperwork completed for the official record. The event was shutting down when we did our pass.
