SSyl's Turbo Super Charger (A20)  

This mod doubles the speed of the Super Charger vehicle mod in game.

In game, by default, the Super Charger increases vehicle speed by 25% and boost (shift-key) speed by 15%. Although this sounds like a decent amount, in-game it doesn't really feel all that much faster than without the turbo charger. This mod aims to fix that by doubling the speed provided by the turbo boost.

This means that the Vehicle Max speed is increased from 25% to 50% and the vehicle boost speed is increased from 15% to 30%.

If you wish to change the values yourself, you can edit my mod to whatever value you want.

If you're playing on a server, only the server needs this installed, but it doesn't matter if the players have it installed as well.
