When my wife starts to yell at me, I just direct her voice under the car and it lifts it right up.

Pat,
I have a set in our race car. I will ask Sam to post some pictures on Monday. We used three jacks, one up front and two at the rear. The great thing is that with the removable allignment bars and left and right handed rose joints we can put the car in the air and do suspension changes in seconds between practice sessions or at least when she is on the track we will (still a few months away from her maiden flight).
Best wishes,
Robert

The guy who used to own Martin Weigolds car put air jacks in his Ultima GTR. I think these items are cool if you are happy to have the necessary compressors or air bottles to run the air jacks. Easy at home with a compressor in the garage but you need ancillary gear at track side or you have to resort to the old fashioned way with regular jacks.
There was the time when our club used to attend the De Tomaso track days at Goodwood. They stayed in the pits, we used the track, a mighty fine arrangment to me! Anyway one of their guys had a number of Panterra's, one being the ex Le Mans race car which he bought for display purposes as the race team had kept back the engine, box and wiring loom! Come lunchtime the De Tomaso club wanted to do a photo session on the track grid as our club does nowadays. This race car was rolled out to the pole position and the owner wanted to show off the brakes. Up came ths massive air bottle and it was duly plugged in. But it did not have enough air to get the car off the ground level. He removed his wheels with the car on the tilt. No disasters if that was where you were thinking as the jacks did hold, but boy he didn't look cool with the wonky car display and the flaff he had to do to get it back on its wheels. And the brakes weren't particularly special either.
Also you have got to be adding weight to the car with the extra steel bracing required to hold the jacks to the chassis plus the weight of air jacks and air lines in the car. A compromise decision is required. But then not many trolley jacks go under cars with 4 inch ground clearance.
Unless you are serious racers, you really have got to want these air jacks to go the extra mile IMHO.
Compare the costs of the air jacks to a secong hand 4 post lift for home use.

I remember one day at Spa where Ralf Shumacher stayed on the start grid when the warming lap was given,with his jacks up! /ubbthreads/images/graemlins/grin.gif /ubbthreads/images/graemlins/blush.gif

Bottles would generally be required as the jacks normally run at 20 Bar (just under 300Psi) - I don't know of any garage compressors that offer over 10 bar.
Also - as the capacity of each ram looks about 2 litres (guesstimate) - 3 rams would require 6litres of air at 20 bar. Therefore a standard diving type bottle say 12L in capacity would give approx 25 to 30 lifts before there was not enough pressure left in the bottle. (assuming 300Bar bottle used)
I guess this is why most teams you see have air systems in their pits comprising twin large (5ft?) nitrogen bottles, suitably regulated. I have no expert knowledge of such systems and am guessing but it seems to make sense.
Would look very cool though - Robert, please post pictures once completed and 'airborne' /ubbthreads/images/graemlins/grin.gif

Any idea what the additional weight would amount to? I'm thinking 40 pounds or so.
