Why is it so few that is using longer 1. and 2. gears in stead of short 3. and 4. Is this only because of the price, or is it a bad thing in a VW with long 1. and 2.??? I Just took a look at Doodah's Box and compared it with Ole's. I can se that Ole's is Absolutely Race only, Doodah's is a little more town driveable, but not much. What about Longer 1. and 2. and leave 3. and 4.??? Then you have more power on 1. and 2. and a more driveable 4. ??? Have any of you tried this? Title: Re: What kind of Gearbox?

Post by: folkevogn on May 09, 2007, 20:53:44 pm I dont remember were the link is but there is several websites were you can calculate what speed you will have at a given rpm if you now the tire size, R&P and gear ratio. I think its a equation in a volksworld magazine from around 1997 with a yellow car with green stripes on the cover. Maybe someone here on the lounge can help you finding one of the links Rune.

To use it, you'll need to know the tire height which you can calculate here. http://www.powerdog.com/tiresize.cgi (http://www.powerdog.com/tiresize.cgi) Title: Re: What kind of Gearbox? Post by: Alan Uyeno on May 11, 2007, 06:06:30 am Late VW OE mexi case - gusseted
