I have seen a couple on cars, at first thought it was a one off piece

Who makes them? how much? thanks, Tim

i am not sure what that air damper/shock? is thats attached to the Fays2 piece on that car. Any info on that?

 

The Watt's link appears to be disconnected from the axle tube(s). I've never seen the damper assembly before but from the geometry it looks like it's meant to damp vertical movement. But still looking.

 

That looks like a cantilever (sp?) shock set up similar to what many mountain bikes have. Weird since it also has normally mounted shocks. I would love to see the rest of that car.

 

That's Twin Turbo's car. I'm sure he'd be happy to share photos. Be prepared to drool and be very jealous.

I also saw that same set up in another car....the upper bracket thing, unless this is the same car with a different rear etc

 

I don't think its the same car, but it is the same owner. IIRC, he has two cars with that setup.

 

Yes, both are mine. The damper is a stewart shock pump, it's designed to pump rear end oil. The gold colored things are 1 way valves.

 

I see that as the car moves up and down it'll operate the damper/pump but where exactly does it pump the oil from/to? Any idea how much it helps with lubrication?

 

from and to the differential, it helps keep stuff cool. These things get blistering hot, especially @ high speeds.

Neet. Never seen one of those.

 

so it does the same thing as an electric pump for circulating the diff oil through a cooler, but its more of a mechanical setup? neat.

 

exactly

 

Have you ever been able to measure the oil temperature at speed with/without the pump? It's the first time I've seen a solution for something I didn't know could be an issue. Looks clever but does need vertical motion to work. Is it custom or universal fit?

 

Anybody ever get an answer to this question?

 

I have a rear end cooler on my corvette and I forgot the exact number but the pump goes on after only about a 1/4 hour of spirited driving and only runs for a short while to cool it down. I think I have it set to turn on @ 150 F or thereabout

 

now thats cool... i was wondering how one would pump the oil through the dif,,,, and there is the answer..

 

You can also simply wire an electric pump and switch it with a temp switch:
