NMCA sealed motor class?
 

I have read the rules and It sure is basic and restricted. Anyone on this site run one of these last year?
Noted they require tailpipes and mufflers. Seems like it would kill the sound appeal of racing. This would also UP the cost of the basic car.
Also what about roll bar or cage?
Cars run how fast? seems like a mid 10 car should have at least a bar and helmet.

Seems like a great class with most races in Div 3 area tracks....

Is that a heads up type of class ?

The one thing that stands out to me about sealed engines is if something breaks, you have to buy another sealed engine or figure out how the NMCA will "re-seal" your engine after repairs are made.

Re: NMCA sealed motor class?
 

Yes pro tree.400. I believe it can be resealed if needed. Specs on we seem very basic built to last.

Re: NMCA sealed motor class?
 

If it works like the sealed crate motor circle track deal, you can buy the bolts on the internet so you can "work" on the motor and then reseal with the correct bolts. Normally an intake bolt, timing cover bolt, and oil pan bolt with breakoff heads. If you go into with an "off the shelf" motor you are already behind and don't have a chance. Well versed in the dirt track area of those motors.

Re: NMCA sealed motor class?
 

I see.
Sounds like the Coyote Stock class with the NMRA.
Those guys are running in the 10.30's now.

The engines cost around 6,300 but then it takes another 13-18K for the ecu., trans setup, and a competitive rolling chassis. (around 25K to be somewhat competitive)

^^^^^^^^^

This.

When these things hit the local circle track, the track owners and promoters were all singing the praises of the crate motors, saying how the cost of racing would go down, the playing field would be leveled, and the days of engine tech, tear down, and cheating were over forever.


Yeah. Right. There's a whole flock of people selling the bolts, and dozens of shops, blueprinting, porting and polishing, installing trick rings, having camshafts reground, and any number of other tricks.

Re: NMCA sealed motor class?
 

Here is the "sealed engine" Coyote Stock class.
NMRA tech will flash the same tune on every car before the race ( or verify the existing tune is the same)
I think the rev limiters are set somewhere around 7500.

Re: NMCA sealed motor class?
 

Normally, the track or sanctioning body involved works with the supplier of the engines to find someone they will contract to repair the engines.

Re: NMCA sealed motor class?
 

Speaking to Chev rep at Indy I was told bolts and sealing method different on these motors than round track motors just for the reason stated. No duplicates to spoil it yet.
Coyote video has good sound from cars too.
Still have not located a person running this class for their remarks. Different set of people I am sure. Not NHRA cross overs.......

Re: NMCA sealed motor class?
 

Dick, sealed engines will always be opened up and cheated up, the only way to keep it in check is for the organizers to acknowledge that fact and actually spend the time, money, and effort on actually policing them. People selling those engines will always claim no one has figured out how to cheat. Because they make money selling those engines on that premise. If people assemble it, people can tear it down and modify it.

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.

Re: NMCA sealed motor class?
 

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.

Re: NMCA sealed motor class?
 

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.

Re: NMCA sealed motor class?
 

I investigated cost and hear CRC car can run 55,000. Then buy a motor,etc. Sorry but don't think this seems like "entry level".
