Bill: in answer to your first question, I don't know? Cost Maybe? On Jim Head's Nitro F/C we use a Manley Triple Spring installed at around 650# Seat pressure. I Cryo all of them when they're new, and we use 'em all year. They're not really a high cost item in the overall scheme of things. Don't forget we have around 10 to 15 set's of heads assembled and ready to go most of the time. What would the initial cost out lay be for Air Springs?( That's about 240 springs without spares) Question #2 has pretty well been answered by Tim. Along with his technical expertise, I can only add, that we use the fuel to COOL the Blower. Our clearances, Rotor to Rotor, and End to End are so tight that with out some liquid to help cool the parts, they won't live. We left a fuel line off (to the Injector) on top of the blower once, and the blower galled up about 50 seconds into the warm up. It ruined it. And as he said, the last thing you want to do is compress the nitro in a screw blower. Heck, we've blown the side out off a block putting studs in with an impac, just with a little nitro in the bottom of the threads....Hey,MAYBE, we'll see our FIRST Stocker Blower explosion this year!! Are they required to have a bag and restrants? LOL.
