Product Review: EVO Turbo Kit Upgrade

October 2016 Product Tests, Feature Viewed 1300 time(s)

If you don’t think your turbo powered Yamaha Viper is fast enough, Evolution Powersports has created an upgrade kit that will boost horsepower to around 220 horsepower using 91 Octane fuel.

EVO’s upgrade kit includes custom ECU tuning that increases your Viper rev limit, reduces its timing and includes three larger direct replacement fuel injectors and custom clutching. The kit raises boost pressure over the OEM Viper turbo system. It is available in both low elevation and high elevation configurations.


EVO claims the kit takes less than 45 minutes to install. It retails for $1,199. For more information contact
