I'm guessing that big box is the transfer case?!?!?!?

that is one way to avoid having to have an expensive 930 gear box (IMG:style_emoticons/default/blink.gif)

Tomorrow night he puts his efforts to the test on the Sumerduck Dragstrip in VA.

all I know is he was winning races with his custom 901 tranny but got tired of being taken off the line - so this effort is primarily to improve 0-60 foot times -as I understand it.

I've studied the photos for about ten minutes. I don't understand how the suspension works. The 4 link is standard drag race issue, but connected to the transfer box that is connected in the center to the transmission that doesn't move? That transmission is going to explode when he dumps it.

Wow. More proof that anything can be done if you're persistent. Wasn't there someone on here a while back wanting to put a powerglide in his V8 914 that described something like this?

I'm thinking the life of that chain is going to be limited. (IMG:style_emoticons/default/burnout.gif)

Edit: Found it. Sounds like the same car.

Yeah, not only that, but even if it dosen't immediately self-destruct, all that mechanical hubbly jubbly will just serve to rob power and add weight. But it's pretty creative, though, gotta admit.

I asked my buddy how he mounted is engine and transfer case - this is his reply.

"They are both solid mounted. The connection between the transfer and
transmission will allow radial movement to allow for flex that might occur
in the chassis due to engine torque. There is no provision for longitudinal
movement. I hope I don't have any movement in this plane. Will find out
tonight. GP"

The rear suspension is a DeDion design. See the "upside down vee" looking rectangular tube structure? That connects the 2 (!) differentials together. It will act like a live axle that just arches up over the transmission. It also has a 4-bar drag car trailing arm setup and a Panhard bar to control lateral movement. It's an OK design except for the fierce amount of unsprung weight. Looks like enough room for a short driveshaft between each differential and the transfer case.

yes - that is correct - a short drive shaft runs from each side of the transfer case to each pumpkin.

Being that the forces are different in drag racing than road racing, I don't know if he needs more tubing or not, but I'd add some diagonal bracing anyway.

Here's one I thought I'd share with you. This guy is putting 1000HP through this setup.

Cool. What is that going in?

I saw a similar lighter duty version of that in a Kitcar called a Zara about 10 yrs ago. I'll see if I can get the pics scanned and add them here.
