3.0 CSL DER TRAUMWAGEN

While looking for interesting technical solutions regarding the suspension and braking systems, I came across the link below—an ad for a car with an interesting build.
The photos of the E9 chassis in the listing clearly show the extent of the modifications.

I didn’t realize how well done this car is. I knew it was an s38 tribute but I didn’t pay close attention to the motor work or suspension fab. Well done!

I have to wonder how much was spent on the fab work using whT In guessing was the #25 reference car. Vink Motorsport is far from inexpensive but they make/sell all of grp 5 suspension parts, clocked bell housing, motor mounts, etc.

Filmed at Thunderhill Raceway's 'West Track'.
Fun track.

Does anyone know what steering rack is installed in that CSL ?

From some of the underside photos, I think it's purely rack & pinion.. no power assist.

Perhaps the pump attached to the differential is for power steering?

On another CSL thread, a forum member suggested the pump near the differential is for cooling the diff fluid. (This thread has links to a lot of unique CSL parts.)

Here's another @Markos post from 2020 that's relevant - custom bell housing or clocking ring?

Very nice shot of the dry sump oil pan:

Oil pump mounted on rear differential and powered off the driveshaft:

Maybe I do not get the question right, but why would you want to have power steering on a race CSL?

 

[rblongboarder]

Here's a shot of the steering rack from the video. I don't see hydraulic hose connections.. this is why I believe it's just rack & pinion. I would love to know what the ratio is.

In addition, here's a photo from the vehicle's page at 2shores:

Also, they cut and re-welded the bell housing to mount the motor vertically.. and I note two 8AN-style fluid connectors. Now I wonder if they're cooling the transmission fluid?

 

[Clubsport_CSi]

As far as I know, Group 2 and Group 5 CSL's have been equiped with rack and pinion setups with ratios from 14.8:1 to 15.2:1.
No idea if this car has one of the rare original parts installed or some reproduction.
