i have a 00 si b16a tranny on my motor and i was wondering what other peoples crusing Rpms were at? it seems like my rpm is pretty high on the freeway cruising at 60mph. at 60mph im at about 3600-3800 rpm. does that sound about right?

 

for me around 60mhp im bout at 3000rmp. for my gsr tranny

 

seems about right

 

i dont think it is, i know mine is at about 3500 at 70 mph and around 3000 at 60, but i got a D16Y8 so, i think ur gearing is shorter than mine... bump, ask someone with an SI

 

gsr has longer gears therefore it will be at a lower rpm at the same speed compared to a b16a

 

at 3000 rpm, you should be going exactly 55mph.

 

on me but would the size of my tires/ rims change the rpm reading. im running 13 inch steelies cause my other wheels got jacked would the change in tire size effect the rpm that much. you say 55mph at 3k but im 3600 at 60.
