altitudeCan some one tell me if there is a conversion to figure difference in altitude will relate. I ride at 3,000 and 2,200 ft. Today rode at 3,000ft. with 48 water, 44 air with 95% humidity. I yield the mph in sigs. I am sure the fog was not helping my speeds.
You think on good day and free mods could be 2 m,ph faster?

I don't know of a conversion table, but i do know that the guys that ride at 3000' elevation usually loose 300 rpm's.
What you need to do is depitch your impeller to get the RPM's up.

I was running at 8,000 rpm,s today at 73.1. I just brought the skis home from Dallas. There the prop was set and was 8150 with a little less speed.
Will free mods make 1 to 2 mph or is not possilble? Also how much top end will get with IC? What about less humidity, will it give more speed.
I appreciate anyones comments

Just filling in the ride plate holes is good for 1 mph.
High humidty kills power.
Adding an external intercooler delivers cooler denser air to your engine which will increase power/top speed.

Thanks for the reply. I am going to fill ride plate holes and on a better day without humidity I will retest. Its possible the adding the IC will get my rpms back to 8150 without changing the prop any at this time.
