The Character i'm looking for a sound-a-like for is Clarence "Razor" Callahan from Need for Speed Most Wanted (and in Unbound as Racer X). He is a Street Racer, most known for becoming the #1 on Rockports Blacklist after stealing a modified M3 GTR from the player at the start of Most Wanted, and ever since losing the car and landing himself in prison, He's been looking to show that his takeover of Rockport wasn't a fluke, and getting "His" Ride back, no matter the cost. Hearing the Mythical ride has made a new appearance in another circuit, he's come to take back what is his (supposedly). 

Due to his old victories, Razor is overly confident, Ruthless and a very sore loser. He tends to talk with a raspy tough guy voice (https://youtu.be/VXvs5p73RYc?si=LYKO7LOHN7vj9uwJ&t=766 & https://www.youtube.com/watch?v=fEmbldz4p_4 for example), but it's mostly an act to sound tougher than he is and can hold a normal tone of voice (See: most of the lines from Unbound: https://www.youtube.com/watch?v=c-UhJkc1rlo).

For the voice lines for this mod, the effect i would like to have with his lines are how he acts like this is the same as his romps in NFS, not realizing that in a game like Dr. Robotniks Ring Racers, where he is racing against some of the fastest things alive, he is a decently sized fish in a abyssal pond, and he only shows how petulant he is when he is actively losing.
