I don't have an exact number of TE jets but I would guess that there were around 6 or 7, I could be way off on that number due to the large number of TE boats on the rope. Most of the TE jets were blown both alky and gas along with a few nitrous jets. I run a black and gold Condor Lightening #507, with a mild blown alky bbc. Since switching to alcohol I have broken two bowls in two races, one dominator and one berk ending up with large holes at ~ the 12:00 position. My guess is caviation is taking them out. Here is a pic from last year.
