lolerz @ 5:55. gives some sort of Dutch hand signal saying "haha, I lapped you in 4 times around this track, now get outta my way, so I can collect my trophy". The sound would almost have to be something from the final drive output shaft, or rear end, because him shifting has no effect on the sound, just overall speed. I'm sure that dash we see is about the only interior piece on this car. So the sound is amplified by bare metal. BTW, ratchet shifter FTW...

umm no, syncros has nothing to do with it...

in your car at home the gears are cut at sort of an angle to engage into each other (except for your reverse gear),,, your reverse gear (like the final drive in the racecar) are straight cut which means they arent at an angle and just kind of mesh into each other... if you have ever reversed fast enough to hear your car kinda make a strange sound, that is your straight cut reverse gear... its basicly instead of the quiet angled cut gears in the daily driver car, he has straight cut (sounds like final drive but may be transmission) gears in his car... im not positive at the benifits of this, but my guess is that it A) may give less resistance in the gears making the transistion from crank to wheels less lossful (is that a word?) or B) it may be able to hold more power then the angled gears as they dont have weak points...

straight cut (spur) gears as opposed to helical found in normal cars. helical mesh at an angle, therefore less noise:

spur

helical

Back when I used to live in the motherland, my dad had a Zastava 750 (Fiat 600 for all intents and purposes with you guys), and that thing had a straight cut, unsynchronized 1st gear. You could hear it climbing the hill to our house from a good mile away.
