Seems that the Spec Miata community is always talking about ways to improve the class to make it fair and keep the prices down. The Mx-5 cup has adopted some great rules. Sealed motors, a spec tire and some really great scrutinizers. Following the last race at Road America, Mazda impounded and took the top three cars to a Mazda training facility for inspection. The inspections are complete and I am proud to say that all three cars passed the inspections. All three cars were from different teams thus showing us a great cross section of the field. below I have posted the E-mail that was sent out to all competitors. The report is extensive. I wonder if these type of inspections could be done at the Spec Miata level?

Here is a quote from the original letter that was given out at the track explaining why the cars were being taken

"The key to any spec racing series is a level playing field and
continuously working hard to make sure that every competitor, no matter
the budget, is able to compete for race wins and championships.
Everyone at Mazda believes, and has been adamant, that this philosophy
needs to be a pillar of all of our racing programs...especially a class
like Spec Miata on the Club Racing level and the MX-5 Cup on the Pro
Racing level."

I congratulate Mazda and SCCA for going the extra mile to make sure that the playing field is equal and I congratulate all three teams for keeping the standards high and racing legal cars.

MX-5 Cup Road America Tech Inspection Report
MX-5 Road America Tech Inspection
After an extensive, in depth examination of each impounded car, all cars were found to be compliant. The following is a list of some the items checked, with a brief description of how they were inspected and how they were determined to be compliant.
The inspection team consisted of Jim Jess, MX-5 Cup Technical Manager, Tim Buck, Mazdaspeed Representative, Nathan Edmonds, Mazda Technical Services and Jim Brown, MX-5 Cup Series Manager.

Engine Coolant Temp (ECT)

Verified ECT matched ambient temp after cold soak

Started engine and verified proper ECT response on warm-up
Ambient Air Temp (AAT)

Verified AAT matched actual ambient and stayed steady with engine warmed up
Intake Air Temp (IAT)

Verified IAT matched ambient after cold soak, stayed steady during engine warm up and increased on hot soak
Air/Fuel sensor operation

Monitored actual AFR input while commanding injector pulse width higher and lower, verified AFR input indicated richer with higher pulse width and leaner with lower pulse width
Operation of Climate control/radio switches for effect on engine management system

Monitored inputs for AFR, ECT, IAT, AAT, Spark Advance, Cam Timing, and Charge Voltage and verified no change in inputs while operating climate control, radio, and other dash switches.
Exhaust Gas Recirculation operation

Commanded EGR stepper open at idle and verified vehicle ran rough/stalled indicating EGR flow is present.

Verified no change in calibration of SCCA supplied PCM

Performed ECT, IAT, AAT, A/F sensor operation, EGR, VCT, Charging System, fuel pump relay and IMTV checks with both SCCA supplied PCM and competitors OE PCM
Resistance of power and ground circuit to fuel pump

Checked resistance of power circuit from fuel pump relay to the fuel pump and fuel pump ground circuit using digital multi meter, verified resistance less than 1 ohm (normal, OE resistance) on each
Fuel Pressure

Checked actual fuel pressure using gauge, verified fuel pressure held without bleeding down and increased to spec within 1 second of releasing pressure
Fuel Pump/Regulator/Sender Assembly

Visually inspected fuel pressure regulator

Visually inspected fuel pump
Suspension Pickup points

Measured upper and lower front suspension pickup points

Tech bulletin 07-09 (dated today 8/21/09) allows this, so I'd say it is a recent development.

The inspections were done before this clarification.

They also no longer require diffs or transmissions to be sealed, only engines.

No one person; let alone team has won 6 races in a row and dominated the series as Jason Hoover / LAMB has done.

Congrats SCCA, MAZDA on the tech....... [thumbsup] [thumbsup] [thumbsup]

Greg - the rule was actually changed prior to the race at Rd America, making polished trans/diff parts legal for that race. The 8/21 notice was a reiteration of that same rule.

Rick
After the race at Autobahn they did take a tire. The Goodrich guys did burn a sample of the tire and checked the off gas for anything that did not belong. All tires that were checked were found clear.

They didn't check for Red Bull or cigars in the glove box Rick, so you're off the hook!

We (as I'm sure the other teams do,) appreciate the time and energy from the SCCA and Mazda to ensure parity.

Congrats to everyone for presenting cars that passed a very thorough inspection. Looking forward to the final rounds of the championship!
