Im one of those guys. I have been racing in the 12.0 index class this year. My truck runs 11.60's all out. Why the hell would i put a cage in my truck and bump up a class to get smoked by high 9 second trucks? The gap betweeen the two classes are way to big.
Because at this point it is typically 10.1-10.5 second SS trucks that win events. The exact same number you would need to be able to run to compete in a 10.5 index. Don't take this the wrong way, but at this point you are much closer to running the 11.90 index, then you are to the 10.50 index.
So far (ourselves included) 9 second trucks have yet to be able to make enough rounds at an event to make a 9 second truck win in division 6. A division that seems to have more 9 second ss trucks then any other division.
Obviously Rob has won a several events, but how many times has Rob had to run other 9 second trucks to get that win? It is well documented that he only runs that truck as hard as it needs to be run (I'm sure we have all seen the in cab of him covering the dsp5 and looking over his shoulder to decide if he needs it).
Only a couple years ago Kevin Morken held the SS record with a 10.97, in essentially a street driven truck, it is now a full second plus quicker, and you need to be serious about having a dedicated race truck. Super Street is the most innovative boundary pushing class the NHRDA currently has. It is the reason that SS is as close to pro street as it is.
If the rules stay the same over this winter, and SS is left as is. My guess is in Division 6 next year there will be six, nine second trucks:
-Devon Lock (he was so close in Edmonton, I wouldn't be surprised if he finds away still this year at Ponci's event to get there. If he ever decides to strap a bottle to it, we will all be looking over our shoulders)
-Brian Spooner (obviously already well into the 9's)
-Shawn Ellerton (He says he is doubtful that it will get there, but he hasn't taken that 6L this far without being innovative, I expect no less from him this off season)
-Daryl Bruneau (has a new big set of chargers, and just needed a chassis cert, to start pushing out some 9's)
-Torrey Werenka (obviously already there)
-Rich Mead (Sounds like he went through a few engines this year, but I'm sure will be back next year, and has already run 9's)
A couple more that could be there:
-Simon (can't think of his last name right off, goes by sweetdiesel on most forums iirc) if they give up on that (imho) silly lenco setup and go back to an allison, or to a duraflight. They could run SS and would be right there.
-Supreme Diesel (Seems to be about a 10.5 truck right now, but I'm sure they could make it happen if they so choose)
-NADP (Rumor has it they have bought Aaron Schaff's old "Pumpkin", it was already running 10.1's at that point)
-Jade Zayac (Depends on which direction he decides to take that truck)
-Kelly Froese (If he changes his mind about keeping it as a street truck)
I wouldn't be surprised if there are several more under construction right now that I either forgot about, or don't know about.
The point being that this is slowly moving to be a 9 second class, and from the looks of things in division 6, people are finding ways to stay competitive. I think too many people are still trying to keep a streetable truck in mind when they think superstreet, but really to be competitive it needs to be a race truck first.
