how do you get the start up boost at the beginning of a race

i dont know how to get a start up boost at the beginning of a race if you even can because one time i think i got a start up boost by accident and every time i start a race i always hold accelerate right after the 2 appears but i never get a start up boost. can you tell me how to do it if you even can do it

There is no start up boost

yes... there .. is?

Yes there is, It's like the speed of a super mini turbo, when it says 2 hold down the accelerate and you should get a boost. (It's not detailed though, it doesn't show sparks coming out of your kart)

Technically, there is no startup boost. I'm pretty sure it just gives you max speed from the getgo.
Another thing about this game that's a little weird.

There's definitely a start-up boost, but as Krazey said it's not necessarily a boost

?

Stop saying that, you don't have to welcome them just because it's their first message and it's useless

I think there is a startup boost, it just isn't detailed as most of the boosts aren't either
