Well first of all, I don't think I can get to 2850 to save my life. To me, the weights are unreasonable for an F-body with the restrictions they have. I currently have a cracked windshield with plans to replace it with speedglass. I'm not going to take the weight of a windshield/waste the money on a windshield all year for a single race. My nitrous setup isn't really good for the rules either. I have the first stage on a plate, and the second stage through a fogger. Also, is a 4150 TB bigger than 102 mm? I was also planning on cutting the frame horns off, but the rules prohibit it. And finally, my fog lights are long gone.
What I find funny is the fact that my car would probably be the slowest in the class, and I'm not even legal for it.

Honestly, I am very disappointed. I have waited 3 years to be able to go to the shootout, and now I really have no class to enter into. Whoever made these rules is definately out of touch with anything outside the NMCA. Maybe I'll take the wife's Z and enter 12.0 on motor or something.
I know these rules were made to keep the gangsta's out of the class, but if you could make..say.. 5 changes, what would they be?
Mine would be:
1. Ditch the F1R
2. Allow a single 76mm turbo with no weight penalty
3. Let nitrous guys pill it to kill it--multiple stages no progressive
4. Allow Lexan with no visible screws or attaching devises
5. make the weights coincide with the spirit of the rules. Has anyone gotten an F-Body down to 2850-2950 w/ driver under these rules?

This new class is huge disapointment to the faster nitrous cars out there. Who in the hell wants to run a factory drysump....... The no drysump and no Lexan is absolute joke. I'm not running a drysump for the extremely slight advantage, but for better bearing life and overall better oiling system. Just because some of us want to run a drysump doesn't mean we should be exluded from being able to race. Whats the average gains from running a drysump, 10-15 hp? Big deal... You can get the same gains in the 1/4 by taking a healthy **** before you make a pass.....
The no lexan deal is not safe either. Ask a friend of mine how it was picking glass out of his face and eyes when his glass windshield exploded at 150 mph..... Now thats unsafe....
I really hoped to run this class at the shootout as its now only about 3 hours from my house...
So unless they add a 50lb penalty for the drysump, and allow lexan......my only chance to race at the shootout is to throw some 315's on the car and run with the big boys.....

You know where I'm at as far as the rules go.
I tell you what I think is sad. At the Ultimate Outlaws 275 race at MIR we had 26 entries with 4 of them being LSx N2O cars. 3 of them qualified in the top 16. Thats more entries than all of the heads up classes that the lsx shootout put together and this race had more lsx n2o cars qualify for it, and this was a race that let in just about anything from turbo mustangs to big block mopars. Its a shame we can't have a good heads up lsx n2o race at the shootout. I would love to see a place where we could all get together and see whats up. I remember reading where Robin said that the lsx nitrous racers weren't dedicated or something to that effect. I think these following racers would be more dedicated and more likely to come to this event than the field that these rules will probably pull. Also of these following racers who would be legal for the proposed rules? These in my opinion at the best of the best in the lsx nitrous world and I think it sucks that just about all of them are ruled out.

I know there are more nitrous racers but I suck at remembering names.

My personal car and all the ones we race dont fit under those rules either. As already posted the top fastest guys that are on here dont qualify either. They should really look at the rules again if they want any really fast guys out there. I know I am not going to modify my car just for the lsx shootout. I know they cant make rules to fit everyone but if the top 6-10 fastest N2O cars cant even compete then maybe something needs to be changed.

Well, I guess I'm out too.... I didn't see the part about stock front frame rails till JMill mentioned it... Damn, I was really looking forward to actually getting to compete this year.
Maybe the Holley "LS Fest" will have some rules that will allow some fast nitrous cars come show their stuff.
If any of you guys want to get together and send them (NMCA) a proposal for some rule changes let me know. I'd like to see some of that stuff changed.

Let nitrous cars run 2 stages of whatever they want
Allow lexan as long as there are no visible fasteners
Allow canted valve heads with 100lb penalty
Change the front frame rule
As of right now, the weights are not reasonable-- why not bump them up another 100-150lbs
The frame rule is unreasonable. Somebody who cut their horns off years ago have no way to bring their car into compliance.

I understand the frame rule. But I think as long as the car will pass NHRA/IHRA tech it should be ok to run. My car isn't unsafe because of how my front end is done, actually it's probably safer than stock.
I have a 2 stage setup too but I could deal with only using one of them with a progressive. I've got some .042 jets for my fogger LOL
