NMCA sealed motor class?

[Dick Butler]

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.

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

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.

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.

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.

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

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.......

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.
