How did nitrous get such a bad rep...?

Just for the heck of it if I ever tear my 422 down I want to try to check a couple of rings to see what my ring gaps are after 4 years of bracket racing and running alcohol. The best pass ever was a 5.98 in 2018. My last pass in in 2019 was 6.04 so after four years the car never lost anything. The ring gap had to open up during that time. Just curious to see how much.

On our 410 Windsor ford, we leaked the engine down before and after the Baja 1000. Before was ~3%. After 47 hours and 53 minutes running damn near full throttle and on the limiter a bunch, and after eating a distributor gear at mile 1107 we saw ~4% leak down. No appreciable difference. I’m not sure if our crew chief measured the ring gap or not upon tear down, I definitely didn’t. But I’ll ask if he did.
