Well it depends on which Si. If it's a 99-00 Civic Si then 4000rpms is about right at 70mph. With my 205/50x15" tires at 80mphs I'm around 4200-4500rpms. With my 215/40x16" tires on at 80mph it's 4500-4700rpms.

we had a post about this over a year ago, everyone agreed that at 4000rpms they're cruising at 72mph. *shrugs* thats what everyone said then and thats what my car runs more or less now. 71-73.
