The pressure relief valve will be more hair-triggered at 25 psi.
These rules, designed to overheat the race engines if cars run too close, will be used in today's morning session.
NASCAR, which had several rules changes already in place before the start of Preseason Thunder, is doing everything in its power during this test to uncouple two stock cars racing in extended runs.
The fastest two car tandem ran 202 mph. The fastest three car draft ran 195 mph. The fastest single car run was 192 mph. The drivers know what is faster. NASCAR can try to get rid of it all they want. The drivers know where the speed is, so in the end, that's what they will end up using. To me, all those changes are going to hurt the 'pack' racing that they are seeking too. It should give those with the single car runs more speed though and help level that out, which I'm hoping. I'd love to see Super Speedway racing where the entire race didn't depend on the draft.
