I believe the next one will be next year. I don't have the gravity or weight of the gas, but it is Rocket Brand 93. They didn't tell us what gas it was till it was too late to get some and test with. I did check the egt in the exhaust, and it dropped about 150 degrees. So that tells me it is like running a race type gas. Don't just go by octane because it is a totally different gas. As for the compression, The higher it is the less timing you should need, especially with nitrous. Since the gas is not a regualr street pump gas, you should be ok, especially with the digital 7. There is no limit to tire or weight or cubic inch or nitrous. That gas could have handled atleast a 250 hit, especially with the weather we were haveing, the car was dead rich. No you were not able to change bottles, so the more you have the better you will be especially with a big hit. As for 32 jets, Just put a rich tune up in it. You can make adjustments up till the point that the car gets tech'd in. There were a few guys running 13.1 with nitrous. Some were running 2 stages of 300 or better. As for keeping it cool, whatever works..anything goes. Hope this helps.
