Looking forward to this class and I'm willing to bet I'm the only M6 car in it! Now that there's plenty of time to make plans who's gonna come run? @joelster, @quik95lt1, @Badhawk, @AChotrod, @Nocturnal Z, @Tyler Wheat, @gump

My dad may join you this year in his camaro josh. Just depends on what we do to it this winter. Right now he's teetering on the edge of es and mod

Good deal!

Well depending on what my car weighs I'm leaning on running this class as a 2nd class to my power adder class. .. When can we register so I can pay ?

Awesome! Should be a great class this year. We will be working on getting preregistration in place soon.

Kyle, not sure your car will meet the rules with your NO2 stuff for the PA class. Look at the last line under "Engine & Drivetrain Rules"

I think that is one thing we need to look at wording on. Having the bottle out and feed line off/capped should be sufficient if you want to run the n/a class. I will discuss it with the others. @firebird_1995 @79LT1Monte

Yea I wouldn't bind anyone up on being able to run both classes. For those wanting to run both I see no reason not to allow n20 cars to run in the na class as long as the bottle is removed and an inspection done.

Ya that's no problem . If rules state you can't run the class because there's nitrous stuff on the car I won't. .. I just want to run a couple classes but 1 power adder class will be ok ...I was just going to disconnect the bottle was all
