Is the '14 CFI4?
Just a question for us that ride from sea level to 7000 plus feet; would we see an advantage as well? going to a lighter spring and moving the Exhaust Valves opening to a lower RPM? If so what spring, IYO, would be the best choice?
As I can ride from the house / garage which is at sea level and be at 6500-7000 in the span of 15 minutes. I'm looking for a setup that can handle that day in day out without monkeying with anything, if that is possible / practical?
Granted I'm in Alaska and our air density difference may com into play on the fueling side of things. FWIW
yes i see this alot in the vipec world. if we get the exhaust valve accuation down to even 6000. rpm becomes more consistant and motor likes it alot, det counts go down. so does pipe temps.
one other consistant in the data is the rpms. rpms will not back off then pick back up. when pulling through the 6000 rpm range.
the lower you get in elevation the more drastic it is.
TRS,
So if I'm reading this correctly the 7041786-03 Green/White spring is the preferred exhaust spring for 7000+?
I have one of Dans motors in a 12 pro 155
THANKS
Trs thanks for the helpful info, I really appreciate you sharing your findings on this. I ride from 8-12k would you still recommend green/ white or would you go lighter yet.
Yes, that is the one I have found to perform the best to date.
