If you aren't reaching red line in high gear, I'd think you either need more
power, less drag (aerodynamic or weight), lower gears or shorter tires. I'd
start with the tires. Drop down about an inch and a half or even two, you'll
be surprised! That made a lot of difference on my car.

The best I could muster with the fenders on was 130 when the street roadster
record was 134, so you aren't going to get much more MPH without doing
something drastic (supercharging?).
