Stage II Reliability and Positive Effects at High Altitude
Currently at Lake Tahoe (6300 ft) with Stage I installed, I'm only gettitng around 7350 rpms. At sea level I'm at 8100rpms.
By purchasing and installing Stage II, would my RPM's go up or stay the same? I understand that by without installing Stage II, I can pitch my impeller and add the Stage III supercharger. This would be great for riding only at 6300ft, but then when I go back down to Sea Level, I would have to make adjustments (injectors, impellers and such), which I don't want to do.
So- Would you advise someone in my situation, who wants his ski to go 70mph in Tahoe to install Stage II? And because I will have friends and family ride the Stage II rxp, what are common problems, if any, by installing and riding the stage II. I ask this, cause the shop is 3 hours away.
I have 50 hours on my Sea Doo and everything runs fine.
Thanks and Happy New Year!

Pitch for sea level with the stage three and your rpm will have to suffer at Tahoe.

there are a couple of complete pumps for sale for $350, I would buy one and pitch it's impeller for sea level and the one on your ski now for high altitude. It only takes a few mintes to swap pumps. After you get your rpm's up to where they need to be at altitude, decide then if you want to do more.
