Beginning with the first race of the 2014 Championship series we will have separate start waves for cars built to SuperMiata specification and all other Miatas.

Sample dyno plot
 

This is an example of a legal dyno plot. Dynojet 248 and 288 only. Must display dyno all weather station values active and SAE correction factor.
This particular blueprinted PTE nationals spec engine is running on E85 and detuned to make this power curve. We have exactly duplicated a 91 octane pump gas power curve from a typical 190+psi compression junkyard NB motor with I/H/E + ECU here.

This power level can be easily attained with the following legal modifications:

• 99-05 cylinder head or complete engine. 100% stock
• Generic exhaust header. Racing Beat is recommended
• Generic high flow exhaust and cat delete. Racing Beat, Borla XR-1 and Flowmaster are good options
• DIY or aftermarket intake pipe and cone filter
• Programmable engine management computer (ECU) and a good tune
• 91 octane pump gas

Optionally, you may add Chinese made >535 gram forged connecting rods and double valve springs to give your engine some protection from accidental ”money shift” over rev. The rods and valve springs to not add power.

Sounds exciting and fun...Too bad I am on the east coast...

Yup. All the cool club racing is in Cali.
I am in FL =no good at all

Another neg rep from the east coast.

I hear California's immigration laws are pretty lax :party:

Yeah, but the cost of living isn't.

A series I'm so excited about I'm willing to de-turbo, change motors, finish the cage, pull all my aero, and buy wheels/tires so I can play. :noes: :)

Tires, bring them to market.

The 205/50/15 RC-1 was released several months ago. They are working on wider 15" sizes with the same diameter for Q1/14 release. Exact size, prices, specs are unknown to me at this point. We tested some prototype wider RC-1's with excellent results. No, we can't share info from those tests. ;).

Oh hell yeah i'm getting into this... will probably have to wait for the 2014 season tho. Oh and for the peeps on the east coast, the cost of living is worth it... grew up in Philly and Pittsburgh and have no desire to go back haha.

A little tuning on Sonny's NA8 "Monty" this morning.

1st plot, bone stock, race exhaust bolted to OEM downpipe, CA91.
2nd plot same with these changes
21" aluminum intake pipe routed to passenger side with cone filter
E85
MSPNP2 ECU

I think all we need is a Racing Beat header to get this little BP05 overachiever to the 140whp cap. Good news for those out there with healthy NA8's that don't want to invest in an NB engine for SPM.

any other changes to the fueling system, or just poured in e85 and tune?

Assuming you meant cone filter on drivers side? (Exhaust side?)

Why would someone want to use more piping to put the filter on the hot side of the engine bay? They're using a megasquirt, so logical to assume AFM is deleted, so no need to go anywhere near the driver's side. Passenger side sounds right, although 21" sounds rather long..

-Ryan

No, its a ~180* bend pipe:

Emilio,

Are you guys using phenolic gaskets on the intake manifolds? Not necessarily on "Moty"...

Ah fair enough. 21" just sounded too long for a passenger side intake.

Just got home. We all had an absolute blast. One 30 minutes rolling start race Saturday. I qualified on pole. Got a really bad start and was P3 exiting Sunset (13CCW).
Couldn't get past Moti for P2 so I just hounded him until he bobbled in Cotton Corners and I got by. Scooted up to Alex driving Enzo and again't couldn't get by. I was cooking my tires a bit so I settled down and stopped poking my nose here and there. Alex was defending and working his tires so I waited and hoped for the mistake. With about 3 to go he overshot Offramp and I tucked inside. Stayed away for the win.

Sunday we inverted the grid for the first 15 minute race. Grant didn't race Saturday so he started last, I started just ahead of him. Got a good start and worked my way up to P2 Behind Aaron Bittermen at the finish. Then we did something kinda crazy (and way fun). On cool down lap we passed pit entrance and stopped at edge of track in finishing order. The last car (Grant) went past and rolled up the front straight to take his spot for the F1 style staggered grid for a standing start. Each driver went over the next so we started the 2nd race inverted from the one we just finished. So Aaron last, me again second to last. At the green Moti (P2) and I got the best starts. All kinds of wheelspin, banging 2nd gear at about 10mph with wheels still spinning. Awesome. Moti opened his visor to yell at Grant to skooch for ward while we were lining up. So when he snapped it shut, it fogged partially. That brief bit of partially obscured his vision going into Sunrise (T1) so he ran wide and had to lift while tracking out. That made everyone behind him check up. I just happened to be in the right spot and was the only guy that didn't have to lift. So I was P2 going into the esses on the first lap behind Alex. Chased Alex down, again couldn't get by so I waited for a mistake. He bobbled Bus Stop on lap 2 and I was able to get by for the win. Great battles all through the field.

Best part of the weekend may have been Moti's BBQ for all the Miata Challenge and SuperMiata drivers and crew. Marinated tri tip, endless beer, Grilled bratwurst. Good times. From now on, MC and SPM are synonymous with the awesome BBQ sponsored by Blackbird Fabworx.

You know the 'grillin is good when the first pics of the race weekend are of the food :party:
