Instead of having to use Livesplit, you can now paste a couple files into your CoD4 directory. This meter is always on, but is toggleable in-game using Numpad 1. The link to the download is in the Resources tab. THIS METER ALSO WORKS ON MULTIPLAYER!!!! You can also edit how it looks in-game by opening the .ini file in any text-editing software.

Can we configure the keybinding it uses? Not everyone uses a full size keyboard

Everything is completely customizable, including keybindings

It is Numpad 1 by default, but you can change it to anything else in the .ini file

Awesome, I'll give it a check out once I feel like practicing some Act3 runs again

im new to this site
where to download?

Go to Resources then click on Speed meter 1.5.0

ooh, nice, so this is like an in game mod, but it's a speedrun timer?

No it just measures your player's current speed. You'll need livesplit to time your runs, or a video editing software's timer

ahhh, I see... thanks a lot for the clarification @LiserdLiserd much obliged.
