Hi i am new to yamaha 4 strokes. But all i want to now is how fast are they with a turbo?? Are they really that fast and quick??? What is the story with these turbo sleds. Thanks

The short answer is that you can have 4 psi of boost all the way to 25+. So on the mild side you have a honest 180 hp all the way to a wild 350 hp. To give you some idea a mild 8 psi of boost would see about 130 mph on a lake and wild you can't even imagine :ORC

Like I told my insurance company. It doesn't necessarily mean it's faster, it just has more power for getting through deeper snow easier and quicker. All depends on gearing.....Mountain sled here.
