stock it depends on if the factory tuned it well if did 82-85 if not 75-82 it really depends on the rider
If it has EFI (Electronic Fuel Injection) there is no idle speed adjustment. The idle speed is adjusted electronically.
The 2009 Arctic Cat 550 EFI has a top speed of around 75-80 miles per hour (mph) under optimal conditions. This speed can vary based on factors such as rider weight, terrain, and maintenance of the snowmobile. The 550 EFI is known for its balance of performance and efficiency, making it suitable for various riding styles.
its pretty fast if your talking about the efi version the power is very smooth when a pro circut full system pipe is added on
If you are talking about the EFI remapper that the LTR-450 made popular, no the Honda 450R won't use it since it is carbureted.
my '00 has 4.7L V8 DOHC EFI Engine(4 speed electronically)
With speed limiter ive had it up to 68 and that's stock how it came so my guess is with out a speed limiter around 80-90
I believe that is a ( C6 ) 3 speed automatic transmission with the 351 in a 1989 Ford Bronco
The speed governor can be easily removed with an aftermarket tuning program like HP Tuners or EFI Live.
EFI, you cannot beat EFI over VVTI
84 mph with a hmf pipe high performence ecu and fuel control
The top speed of a Polaris Ranger 500 EFI is approximately 40 to 45 mph, depending on factors like terrain and load.
