Re: NMCA sealed motor class?
 

So far, the NMCA has been doing a good job of policing the DR525 class. They are very serious about keeping things honest. The seals are much different from the SBC round track engines. To my knowledge, there are no authorized rebuilders for this program. I have also had the chance to look at a lot of timeslips from this class and have seen nothing that makes me believe that the motors are being tampered with.

Re: NMCA sealed motor class?
 

I race a Sealed Coyote in the Sister class in NMRA. The Engines are not rebuildable for class. If it breaks, rebuild it, sell it, and buy a new sealed one.
We run with the NMCA at 2 events a year. This year was their Freshman year and had 5-6 cars. They should have upwards of 10+ next year.
The NMCA class outlaws Stick Shifts. The fast cats are running Metric 200's. If a Stick option was available I would run this class also.
So far I feel NO ONE has a "cheater" engine on our side. We have 20+ entries and most of the cars are within 2-3 mph and the fast guys are withing 1/2mph.
The racing is cool, close and pays well.

The seals on these engines are not like the seals on the 604 crate engines. The engines are built at GM if you can talk them into changing one only for you Please PM me. LOL.

Tech man said" they Flash them between each round" I assume that's a computer check to be sure no change in program has been introduced by the racers.

Dick, I actually like the spec head deal better because of the reasons already stated. Spec you'd be allowed to work on the engine, and the manufacturer could make the call if the heads are illegally modified. But that's just me. Spec head does work in roundy round, and 360 sprints to cut costs. Bash away.

Re: NMCA sealed motor class?
 

Randy, I tend to agree with your opinion. Econo Mod rules would allow use of an already built car that was a legal SS or Stocker. Sealed motor class needs construction of a car with its own set of specs. You could not just change motors and move to Stk or SS without more money on chassis.
Also the sealed motor does prevent someone from experimenting with settings, fuel, cams etc but this could be the cost saver area.

Re: NMCA sealed motor class?
 

The DR525 class rules were written with Stockers in mind. It wouldn't take much to convert one. In fact, the two front runners this year were Camaros built at the COPO build center (CRC).

Re: NMCA sealed motor class?
 

The NMRA side will put the " Spec Tune" in basically every round. It will overrite whatever tune is in the PCM and rewrite the "Spec Tune".
If someone was cheating in the "Flashing" they are the worst cheaters ever cause the Quick Cats in the class incrementals add up.

Re: NMCA sealed motor class?
 

So are they "Cheap entry point"? Is there a contact person that helps get the car built for you?
Stockers may have tubs correct? These cannot. can have springs moved but not rails as I understand.

Re: NMCA sealed motor class?
 

If you are asking about the CRC cars there were still a few available a while back (2013-15 models). You can contact copopartsdirect.com to find out what's left. I have been told that there will be no 2016 CRC cars.

As far as the rules go, it would probably be best to direct your questions to the NMCA if you are thinking about running a car.
