We had a flat tappet Cup engine in the car doing development for the Cup series. We raced Pocono with a 4.33 gear and a .91 overdrive turning 10,400 in every gear. That is until we got taken out near the end, on a restart by a field filler! Lol
That was pretty much the end of an era, as Nascar implemented a gear rule shortly there after.
The RPM flashes you seen in the truck deal were mainly from the poorer quality telemetry vs Cup, and the many obstacles (overhead bridges ect) at the Cota track interrupting the signal.
The TV has access to this stuff but you guys on pit wall don’t?

Obviously I know you can download it after the session.

Truck and Xfinity no. I'm not sure what is available to the teams live during the Cup race. The capability is there for sure, just not sure how much Nascar allows live to the teams.
