Turbo Golf Racing

This is unlikely to unlock in normal gameplay as you will be getting 1-5 pickups per hole.

The best way to unlock quickly is to go to a custom match with a boosting partner or 2nd account and sit on a powerup, activating it, until the clock timer runs out.

I used the map "velocity valley" and queued it ten times so I could sit there the whole 5:30 and then queue into the next map without having to relaunch the match. To go from 42% to 100% took me about 25 mins, so the whole amount probably takes 45 mins.

Here's how you can do this achievement as fast as possible:

You'll need a second account or a friend

Set up a private custom game on any map, I used Velocity Valley, I would only recommend putting 1-3 rounds (rounds are determined by how many times you add the map), I do a low number of rounds just because tracking can be buggy.

No go to the Pickups menu in the custom game settings and remove all powerups except for the boost refill (looks like a jar with lightning) Also remove bots

Now start the game, and once you're in, move your ball so that it is sitting on a powerup, and then go sit on one with your car, now you can just walk away and come back in 5 minutes when the timer runs out. This should yield 15-20% each hole.

Basically the boost refill doesn't require manual activation, and your ball can also pick up powerups, so you get double the progress with very little effort.
