Afrojack -- Bruce Jenner's a 'P**sy' ... I Drive WAYYY Faster Than That Guy!

Not everyone's impressed with Bruce Jenner's race car driving skills ... especially not Afrojack, who tells TMZ Jenner's a "p**sy" behind the wheel ... 'cause he ONLY did 160mph this weekend.

FYI -- Afrojack is a hardcore speed-aholic ... and while standing next to his new Ferrari in L.A. last night (he crashed his old one), the 26-year-old platinum-selling DJ scoffed at Jenner's achievement and told us he's gone wayyyyy faster in his own cars.

"I did 216 in my RS6 [Audi] and I did 210 in my Aventador [Lambo] ... so Bruce Jenner can kiss my dust."

Two things:

1) LOOOOOVE this guy.

2) Sounds like a challenge to us.
