The 1999 Polaris 700 XC SP snowmobile is equipped with a 700cc liquid-cooled engine that produces approximately 130 horsepower. This snowmobile is known for its performance and agility on the trails, making it a popular choice among enthusiasts during its time. The horsepower can vary slightly based on modifications and maintenance, but 130 is the standard rating for this model.
140-150 depends on aftermarket parts, miles, use, so on.
If it is a Powervalved SRX, not an SXR, 135-140 is a safe bet, depending on your jetting and other carb settings.
