How to speed up car in Blueprint Please

I’ve been trying to get the default car (either basic or advanced) to be more arcade’y’ without luck.

I’ve seen an Unreal video showing to find ‘engine’ and up the RPM, mess with the curve below it… I’ve tried that, saved, reopened etc. and still can’t get a snappy takeoff.

Can anyone tell me how to drive a little crazier?
