As a Super Cup newbie, how much pressure & capacity do I need on a tank to operate the jacks? Thx.

You need to get a nitrogen tank charged to 2000 pounds or so, then get a regulator and hose that can handle 500 pounds pressure. The car will lift with 325-350 pounds pressure.

Hi Jay, and welcome to the club. Jim's car, what with all the top secret carbon fiber bits, F1-style ground effects (so advanced, they even work while parked in the paddock), and TPHI ('tuned port helium injection'), will go up with 325-350 PSI...most other cup cars will take around 400 PSI, and even then the left rear may not always pop all the way up right away.

Seriously, I've always run mine at 400, and that's what we used in Grand Am last year with the GT3RS.

Seriously II - Jim's car doesn't have any of that stuff (well, maybe the helium), but he is still wicked fast, so bring your "A" game....

Hi Nick.. is this another opportunity to shamelessly ask you about those videos? <img src="graemlins/offtopic.gif" border="0" alt="[offtopic]" /> And even with the lowered ride-height you figured out the RS ground effects I spent $45K for, huh? Yeah, I guess you're right, quite often I have to give the driver's rear quarter a little tug to get 'er up, but the direct helium feed to my helmet does help a bit. <img src="graemlins/jumper.gif" border="0" alt="[jumper]" />
