[DeTomaso] Hydraulics for Pantera - Dark Depression Sets in after Silver ...

[Mad Dog Antenucci]

Thanks Ken....Engineer Dick is on this and should have some feedback within a few days from the pro's.

    I don't know much about them or what is available, but I think you can order a spring with varying spring rate over the length of the spring.  That way, part of the sping provides a normal spring rate for normal driving but may be 100% compressed if you hit a big dip.  The rest of the spring has a higher spring rate selected to not 100% compress over any dip you are likely to encounter.  If there is room for something like this, it would at least avoid the shock of bottoming out.

    You're right Ken.....the first serious dip is on the course notes so you can prep for it but you also can't dry run the road in advance or the run the dips at speed or anythng but legal speed.....what are the progressive rate springs you mentioned??

  I didn't think the active suspension looks ahead, I think it responds to the recent and current sensed conditions. It wouldn't help when you encounter a first dip in the road.

Are there progressive rate springs available? that might be the best way to avoid bottoming.

Seems to me that issue is not to raise up but to stiffen up when needed so 
that you don't bottom out. Benefit is that you keep the aerodynamics and the 
alignment and you can quickly switch back and forth. 

Many years ago, cars were getting "active" suspensions that would read the 
road ahead and adjust the spring/shock rates accordingly. And there are cars out 
there today with "adaptive" suspensions that vary the spring/shock rates by 
selecting "comfort" or "sport" mode. That would be the concept but would have 
to be adapted to radically adjust the stiffness when the dips were coming. 

Issues? Is this really a workable solution. Stiffening the chassis and 
suspension mounting points to handle the increased load. Testing to see if you would 
go airborn. Adapting the control mechanism to get the stiffness required and 
to have it activated/deactivated in a timely manner. Tire loads. A button on 
the steering wheel would be my suggestion for activating it. I'm sure there are 
more.

Google adaptive suspensions.


This reminds me. Do we have a Team Pantera Racing fight song? Here's my 
suggestion:

I want to be an open road racer
I want to live the life of danger
I want to go O R R (got to get the meter/beat/pauses 
right on this one)
I want to beat some newer cars (newer? need help here)

I forget the next verse. That's the best I could come up with that still 
rhymes. Please feel free to make appropriate changes.

I propose that all ORR Panteras have loudspeakers and that they blast this 
out in synch at any pre or post race gatherings and at the starting line so as 
to intimidate the competition and to charge up the adrenilin level of our 
racers.

Whaddaya think?
