So what the difference between a normal gear set and a straight cut?
Name: Brent

Family: '15 Jetta Sportwagon
Fun car: '92 Blue Karmann Crabby Cabby Mods: Coils, front and rear swaybars, LED interior lights and some other old things.
I talked to the previous owner about noise level. He had a similar 8vT setup to mine. He was saying that its not deafening by any means and that there were other things in the car that were around the same noise level. So Im not to worried about it.
The difference between straight cut gears and your normal transmissions heli cut gears are:
In short, helical gears operate quieter than straight cut. Straight cut will 'whine' the faster they go but offer both A. More directional application of force allowing for less power loss. and B. Higher acceptable loads until failure. Basically making the transmission stronger and more efficient. However though, like noted before, car manufacturers don't use straight cut due to the noise the transmission will produce.
