With those predator engines gearing is more critical than other classes, a lot of guy's here were gearing them to close to the clones as far as front driver size, our small fast momentum 1/8 th mile track clone is a 14 front driver, when I told guy's with predators to try a 17 front driver they resisted but eventually tried, then when I told them to try an 18 driver they thought I was crazy but it seems best, then same with Air pressure here it is a 33's only rule on an 11 track and when I told them to double Air to start out they again thought I was crazy, but little over double the air the clones are on is the ticket, Bottom line the stock predator is all about momentum.
