NMRA Coyote Modified - 2014 Racing Season

[Sharad]

Is anyone here building a car to compete in this class? I had a long talk with Mike Galimi at the NMRA about Coyote Modified, and it seems like it's going to be a great class. With the inducer size limits, centrifugal blowers will be T-trim or D1SC, PD blowers are 2.9 Whipple, 2.8 KB, or TVS2300, and turbos are 67mm IIRC. That's a big step down in size from what a lot of the Coyote heavy hitters like JPC, Evolution, and Beefcake are running. It seems like the class is wide open for newcomers to make their mark.

I suspect that this new class will be great for the development of Coyote upgrades. I'm looking forward to seeing how this all plays out.

 

[lostsoul]

I think they did that so BBR can compete too..

you know there is only so much speed you can build up by the 60' mark..

 

[SC2011GT]

The class is so heavily biased towards nitrous, no supercharged/turbo car can possibly compete.

How fast do you think a nitrous car is going to be? Just thinking out loud here, the 2.9 whipple at 3650, that's around 200lbs heavier than Holbrook ran 8.50 with this year in his 13 CJ. Comparing that to this NMRA class you wouldn't be limited to stock pulleys, can run any rotating assy parts you want, can work on the heads/intake, can run a lockup trans, get a transbrake, and wouldn't be on a 9" tire. That all adds up to a 2.9 car being pretty damn fast, and I have to wonder if you could cram enough nitrous through a little motor like this to keep up with it.

Considering the nitrous cars are 2900 lbs, I'd be willing to bet they will be pretty fucking fast. A 750 lb weight advantage over a twin screw seems a little ridiculous to me.

They are also mandating that the twin screw run a completely stock GT500 throttle body. That certainly isn't going to help that poor little 2.9 when it is really being leaned on.

I think, and this is just my opinion, they need to either level the weight minimums out across the board, open up the compressor size selection, or allow dual power adders at 3650 lbs.

Evo ran what, 8.50 with a 4.0L whipple/Turbo 400/good size tire/far less than 3600 lbs. I don't think they went low 8s until they hit it with some nitrous.

I could be wrong, but I'm betting a 2900 lb nitrous pig will clean house on that class. Will be interesting to see!

 

[BMR Tech]

Will be interesting to see.

All I know is, a 2900lb car with a good foundation (engine) and a lot of nitrous, can definitely be fast...but will be much more tricky in terms of consistency, I would imagine.

 

[konablue11gt]

I think I read somewhere Terry (Beefcake) is going to run the blue car in this class with a smaller Vortech

 

[Bud]

Nitrous could be good if somebody has enough money to keep shoving blocks/pistons in every event. No restrictions on the nitrous and 2900lb could be interesting but how much nitrous can you cram in only 302 cubes and keep it together.

I see 68mm turbo with a T4 flange allowed, but no mention of where they measure it...

 

[Sharad]

You can only shove so much nitrous through a 305" motor until you reach a point where bigger jets don't yield more horsepower. I'd run a D1 if I was building for the class. But look at what Jake Conant has done with his TVS2300. Put THAT on a coyote instead of a terminator!

^^^^^
This seems to be the general consensus, that you can only get so much nitrous into the engine. We should see pretty quick if the NMRA is mistaken on that assumption along with everyone else.

The biggest challenge for me will be the 3250lb race weight....

Ding ding, we have a winner. Plans for the car next year are 2 fold. A smaller blower for coyote modified,

and a bigger blower to get after some 7's.

Should be interesting on what vortech can come up with for me as far as a head unit. There is no designation of a "t" trim. There is a designation for inducer / inlet size. I'm guessing we will still make 1000 rwhp or better on what they come up with. Same thing we ran 9.0's on at 400lbs heavier, without a transbrake.

You should leave the blue car as an all out car and if you want another class car, build a coyote stock car. Now that is a fun class to watch and listen too.

They are also mandating that the twin screw run a completely stock GT500 throttle body.

That just made all of the PD cars uncompetitive.

The rules I see say it requires M-9926-CJ, which isn't even made anymore.

 

[SC2011GT]

The rules I see say it requires M-9926-CJ, which isn't even made anymore.

"Roots-superchargers and Twin-screw are required to utilize an unmodified factory Shelby GT500 throttle body."

The number is M-9926-MSVT which is a factory 07-14 Shelby throttle body.

The CJ65 is the Cobra Jet twin blade and the SCJ is the big single blade. Obviously, neither of those are "factory GT500 Shelby throttle bodies"

If you could run either one of those, it would be far better than the little choker piece of shit they are specifying.

Also, if you were to choose to run a 2.8 Kenne Bell you would have to build a custom adapter to run the Ford throttle body as the KB accommodates either the stock coyote throttle body OR the 168mm KB throttle body.

Link? That's different than what they have here: http://www.nmradigital.com/wp-content/uploads/2013/10/2014-Preliminary-Coyote-Modified.pdf

both are CJ throttle bodies, but only the mechanical linkage one is listed as "available" on Ford's site.

I wonder if that will be/has been changed in a newer version of the rules.

 

[Wicked97]

i think we could get to the front with a 67mm

Turbo is a powerful drug!!!

Hell we already went 7.87 with a 76. I think the goal is to keep this class in the Mid 8s so we dont have to 25.5/25.2/25.3

 

[Wicked97]

BTW i think its stupid they will not allow radials, olnly slicks

Fu*k Slicks

 

[dysan]

Wow...what kind of crap is that not allowing radials? I don't even have a coyote engine and that is pissing me off

I've been on Galimi about this.

I think it's the stupidest thing in the world.

They say people will complain.

How can you complain if you get your choice of tire.

Makes absolutely no sense.
