I just noticed the date of the original post so you may have found it by now but fuck it, here is what I've found for ya anyway:
From what I was able to find it is actually a mix by Dodgyone called 'whoo haa get phunked up'. It's actually a mash up of Busta Rhymes 'Whoo Haa' (thanks, captain obvious) and Carl Craig's mix of La Funk Mob's 'Motor Bass Get Phunked Up'. Which may explain why you were having trouble finding it in the first place since it isn't actually a mix by La Funk Mob. Anyway, knowing that information & Google being your friend you're now set... but since Google is my friend as well I've compiled it all here for you.
More information can be found at http://www.discogs.com/release/932900. It is in 12" Vinyl format (which was previously mentioned) Tracklisting: Whoo Haa (7:35).
I've been able to find 3 formats that you can download; unfortunately none of them are the full version.
The first one is from http://www.umerkura.cz/shop_files/13742.mp3 (right click>save as) and is only 1:06 in MP3 format.
The second one is a .ram file so you'll need RealPlayer (www.real.com or try http://oldversion.com/program.php?n=real for previous, less shitty, versions of RealPlayer... you can find lots of other programs on there as well btw). The link for the .ram RealPlayer version is http://www.dancerecorRAB.com/audio/64460.ram and is 2:11. If that link doesn't work go to http://www.epimps.tv/hiphop/hihop.htm and it's about half way down the page.
The third one is http://www.groovedis.com/m3u/dodgyone.m3u which will play in WinAmp and is 1:34.

You'll also find a handful of other information on Google by searching for Dodgyone - Whoo Haa; Most of which are places selling the 12". Unfortunately, I just don't think you find the full version unless you buy the 12" and rip it. If it was out there I would have found it. That's all I've got, hope that helps!
