Hey John,
In the past when I have been there, they incouraged all non winning cars to run time trials between rounds, to give the cars still in compitition a chance to cool down. Once when I went out in the first round, I was able to get ten runs in before they shut the track down for the night. Tech inspection is done at the track by official inspectors. It is a pretty general lookover. I have a very stock FFR MKI, the only thing they made me change was to add a radiator overflow bottle. I installed an
antifreeze jug with wire ties and it is still under the hood to this day. Make sure that your crankcase breather is either vented to the intake manifold or a catch can. Also have a good helmet with you. They seem pretty lose until you break in to the 11 second zone, Then they may require a fire jacket and roll cage.
