Title: IRS vs Swing Post by: louisb on September 17, 2008, 02:46:05 am Other than strength and lower cost, is there any real advantage to swing vs IRS in a hipo VW? I am kicking the idea around of converting the '67 to IRS. (Using an IRS pan that is in better shape than my SA pan.) If I did this I could either go with a Type 1 5 speed or maybe even one of the new berg Type 2 5 speed conversions. Mike Gagen's red car had a bus five speed in it if I remember correctly. Do they make a limited slip for the bus box? Then the weak link would be the CVs and stub axles. Any thoughts?

Title: Re: IRS vs Swing Post by: Zach Gomulka on September 17, 2008, 03:59:41 am As far as I know there is no LSD avaliable for the T2 trans. I hear the "hot" setup is using a locking diff from a Syncro Vanagon.
IRS will always ride and handle better (at the cost of added weight, and more parts that may fail), but a properly set up swingaxle isnt anything to sneeze at. You'll have to figure out what is important for you.

After destroying 12 swingaxle transmissions in my '67, I decided that the race bug I'm building will be an IRS car with a bus gearbox from the start.

These are 091 ZFs from Bruce's gallery on the samba (http://images.thesamba.com/vw/gallery/pix/368381.jpg) (http://images.thesamba.com/vw/gallery/pix/208008.jpg) Title: Re: IRS vs Swing Post by: karl h on September 17, 2008, 07:03:30 am in germany (and austria for that matter) all the ambulances had LSDs, T1 and T2

Title: Re: IRS vs Swing Post by: Diederick/DVK on September 17, 2008, 10:02:15 am so, what's stronger about a bus tranny?
the reduction boxes? ;) Title: Re: IRS vs Swing Post by: Bewitched666 on September 17, 2008, 12:19:33 pm I use a mendeola in my pro stocker ;)
Title: Re: IRS vs Swing Post by: benssp on September 17, 2008, 13:27:50 pm so, what's stronger about a bus tranny? the reduction boxes? ;) Think they are referring to a bay bus box(091 6 rib case), lots of the outlaw flat four use them and manage to break anything but the box! ;D Title: Re: IRS vs Swing Post by: louisb on September 17, 2008, 14:20:26 pm After sleeping on it I think I will stick with the SA pan. Its was just one of those ideas that come to you late at night. Thanks for the input thought.

Title: Re: IRS vs Swing Post by: Germanlkmanx on September 17, 2008, 20:11:49 pm Quaife make a LSD for the 091 trans. 091 (and the IRS that goes with it) is the only way to go IMO if you're gonna get serious about going quick.
tom. Title: Re: IRS vs Swing Post by: Bruce on September 18, 2008, 08:29:28 am Quaife make a LSD for the 091 trans. You sure about that? http://www.quaife.co.uk/shop_category.cfm/category_id/1274/category_id/1274 Look at the product code for the Combi diff then compare it to the one for the Beetle diff with Bus spline. Pic is the same too. Peloquin makes an LSD for the Bus 'box. ZF made 2 completely different LSDs for Bus 'boxes. 002 and 091/094 |
