Henrik,
I have had experience with the CNC throttle on a sand car as mentioned above, used it for about 3 years.
Pros: can be routed and configured "sometimes" easier than cable. That's it!
Cons: The hydraulic line is as thick as any Morse cable therefore still has to make "sweeping" bends.
Response can be sluggish if <u>all</u> the air is not removed from the line, similar to brakes. Comes with a bleeder reservoir located at the carburetor\throttle body end that has to be located at highest point of the cable to expel all the air from the line.
Attention has to be paid to the return springs in order to put correct pressure on the hydraulics and have the throttle return quickly.
Hardware at the throttle body end is large and cumbersome, partly due to resevior.
IMHO, Morse cable is far superior, less worries, better response and can be contoured to the same radius (if not tighter) as the hydraulic line. And finally, if I’m not mistaken hydraulic is considerably more expensive. I would never consider hydraulic again, my 2 cents /ubbthreads/images/graemlins/smirk.gif
