Track Day Prep.

[CurtiSS 69]

We have talked about before but after you return from the track, or at the track after doing 4 or more 20 minute sessions at 6000+rpm. It is a good idea to check key fastners for tightness. You will not believe the things that will come loose after some track work, or better yet paint a witness line on drain and fill plugs for fluids and brake attachment points. I know now why racers use safety wire.

Bring an infrared thermometer and check engine, transmission, power steering, and differential oil temperatures. If your running conventional oil consider 260F to be a maximum and Redline 300F. If they are higher than this a cooler is needed. Caliper temps should be 40F below the boiling point of the brake fluid too.



Another thing to be concerned with is fuel pressure. You don't want to lean out under severe conditions and lose a piston, or lose a battle. Oil isn't the only thing that flows away from the pickup. This is something that will only show up at the track as the car is under full acceleration and hard cornering forces most of the time. Having a carb with large float bowls helps cover this problem up.
