I have stock gearing for a 99 srx700 which is 23/37. I am about to change the chaincase oil and debating if i would benefit from an 01 srx 700 gear ratio which is 23/38. Would going from a 37 to a 38 make a difference and also whould i have to change my chain (15) to a 01 chain (13)? I am looking for best gearing for 1000ft radar run. Right now my sled engages at 4000 rpm and shifts at 8500 with 8500 being max rpm. I run 100mph-102mph gps in 1000ft across the lake on hard pack...(not shaved track). Obviously I would like a few more mph in 1000ft. any input is appreciated.

seems like that calculator gives too high of a mph value???
its because you figured 10 tooth drivers, not 9 tooth which is what a srx has
I know I put in the 10 tooth sprockets as bluemonster wants to hit 120 mph this should give that mph LOL. This calculation with 9 tooth drivers was 122mph but we all know that the Dream O Meter is 10-12mph off
