After reading some of the responses, I decided to get out a napkin and scribble down a potential payout structure. I'm going off the assumption the full $1.3M is for the 3 pro classes and none of it is used for any additional classes like alcohol dragster/funny car, top sportsman/dragster, etc.
Top Fuel and Funny Car:
Winner - $250k
R/U - $85k
Semi's - $30k (x2 drivers)
First Rd - $20k (x4 drivers)
Total Payout = $475k per nitro class, total of $950k
Pro Stock:
Winner - $125k
R/U - $45k
Semi's - $20k (x2 drivers)
Quarters - $15k (x4 drivers)
First Rd - $10k (x8 drivers)
Total Payout = $350k
Again, I took all of 5 minutes putting this together. The point being, if the payouts are structured something like this, I think you'll have plenty of racer's attention. I believe a Runner Up in the nitro classes pays, what, $22k at an NHRA national event? Using what I put together, just qualifying for the 8 car field and losing in the first round you would be paid almost as much as a runner up at a normal event. I would fully expect teams to work on getting additional sponsorship dollars or potentially pay out of their own pocket, to attend. I'm expecting the fields to be full and to see some top notch racing. Just my initial thoughts on this...
