Project Turbo Snowmobile

[crazy_skier]

one thing that I remember from when I was looking into turboing my yamaha viper is that you still have to keep the bulge pipes. These are what pull the exhaust out of the engine and keep it running good. You could get away without them but your low end would be horrible. Again, I would look into adding some secondary fuel farther upstream to help compensate for the boost pushing the mixture strait out of the cylinders.
