From the sounds of things, there could be 6-7 strong cars coming for this class. Add in 3-4 more folks that I hear are trying to be ready in time, and we could have a super turnout.

I'm not sure if I changed that on the final rules submitted to Holley, but I'm sure we can work this out. Doesn't seem like a big deal to me either way. I'm sure the track/NMCA just want to keep the starting line from being a parking lot for ATVs, golf cars, etc.

I don't understand rules like this. Have any of yall ever run a nitrous car? How are you supposed to tune the car if you can't tow it back and check the plugs. I suppose its fine for a turbo or blower car but I would not run my car anywhere if I did not have the option of towing it back if I wanted to.
We will be at the Yellow Bullet Nationals the week before anyway running a real race with a real payout. I don't like how you can act like we would cheat if we could tow back. They just had a local race here with a minimum weight of 2800 and the payout was $2000 and we didn't run that because they wouldn't let us tow back. I couldn't even get below 2800 no matter what but that wasn't the point. I could have got an easy 2k since only 2 cars entered and the fastest pass was a 5.2x.
If anyone and I mean absolutely anyone want to run an ls car in 275 trim on a real track under some real rules come on up to MIR one night and race with the best ls nitrous cars in the country!

If it's anything like I have seen how they have worked to make the LS Fest a success, I'd bet this will be fixed so the likes of you and ATV can get down to BG for some fan "eye-opening" to who's really making waves in the LS x275 community. I know i drove my *** all the way to valdosta earlier this year to get a glimpse of your and ATV's cars in action. I was lucky to see yours at least.

I for one wanna see the BADDEST of the BAD LS cars at one place!!! I think that's what everyone else wants to see too! None of these guys can build a car strictly for LS racing series. Most of them build their cars for local X275 classes because that's more realistic in regards to payouts and being able to still be somewhat local to race.
It seems like such a petty thing to not let them tow the cars back. I don't know one heads up nitrous guy that doesn't shut off and check the plugs after each run. Seriously can we not just have one good race at BG? If you guys would see how bad these guys wanna run you will see the BIGGEST turnout ever for a LS Race!!!

This is a BS rule. Beech Bend has Plenty of room at the top end of the track. This is a one race deal. Why not cater to the guys willing to come race and lay it all on the line? Nitrous and N/A guys tune off plug readings. Anyone with half a clue knows this. Having to drive across the scales is a BS excuse to the whole "Keeping Everyone Honest" arguement.

Not so much throwing weight round. It's about the LSX crowd having an event Soley for LSX powered cars. Then having a supposed all out X275 style 1/8 mile class. Then getting BS rules thrown in that might keep Top Nitrous guys from showing up. This coming from a Die Hard Turbo Guy.
Getting DQ'ed for towing across the scales is a joke.
I say make it reaL EASY.
-LSX powered.
-275/60/15 DR Tires.
Let Em Hang.
