Milan (MI) includes a Nostalgia Comp Eliminator class at three of their vintage oriented races each year - the Detroit Dragway Reunion, Kickin' It Old School, and Nostalgia Drags. It is a 4/10 Pro Tree Index based (1/2 second increments). Declare an Index and qualify off that index - closest to the number qualifies #1 on the laddered pairing. Higher qualifier has lane choice.
Usually its race two days, two separate races, two qualifying runs and eliminations each day. Payout and entry fee is the same for each day. Entry fee is $50. Winner gets $500, runner up $250, semis $100. Guaranteed purse.
I know some are going to say,"Heck, I won't even take my car out of the trailer to run for only $500!"
We usually only get eight cars. If you do the math you'll see the track loses money on this eliminator. But it enhances the overall quality of the meet and they're good with that. And if I win first round I actually make money.
I keep my older "The Last Logghe" altered tuned up just for these races and usually run the 10.50 index and as such, am always the slowest car there. [ I rebuilt the car several years back to slow it down so I don't have to jump thru the NHRA 9.99 chassis re-cert hoops for a car that only gets raced a few times a year.]
For FEDs and center steered altereds and funnys. Its usually about 50/50 FEDs/ altereds. Trans brakes are OK (hey, if you need a trans brake for a 4/10 tree knock yourself out, buddy). The track tries to make it an all-inclusive bracket without allowing modern Super Comp and Super Gas cars to play.
Its some of the funnest racing I do. None of us take ourselves too seriously. Its a good group. And when a fan came up to me and said when I ran a 7.50 AA/A the fans were on their feet and it was the best race of the day, I felt good. (I won that round LOL).
