Hello everyone!

Just figured I would let you all know how the 1st West Coast National Race at California Speedway (Auto Club Speedway) went this weekend.

SCCA National office sent out the National Tech representative to tech the cars throughout the weekend. The group was very impressed with the thoroughness and commitment to ensure that the competition stayed level throughout the weekend. The tech official checked the top cars as well as a few random cars from each Spec Miata Regional Qualifying, Regional Race, National Qualifying and National Race session.

Items that were inspected throughout the weekend:

Restrictor Plates
Steering Racks
Visual Suspension Check
Intake Tracks
Airboxes
Throttle Bodies
Intake Manifold
Under Dash Piggyback Visual Check
ECU Check
Cam Gears
Compression Ratio (Whistler)

They also scaled the entire pack of 23 SM cars and found some mid pack cars were under weight.

Only one car was DQ'd during the weekend for a tech infraction:

The person had clearly been sandbagging qualifying to skip being tech'd which became apparent during the race as he motored by the top qualifying cars. Though he locked up the brakes and almost careened off track through 2/3 of the corners he consistently pulled away from the rest of the cars. The top 6 cars were held and compression ratio's were checked with the whistler. All of the cars passed easily except Mr. Motor who checked consistently .4 over on each cylinder.

Overall it was a great weekend! The Tech was everything we have hoped we would see at every event to assure this blatant cheating doesn't occur. I was happy to see also that our local tech officials were paying close attention to what was going on so they can continue this process.

Happy Racing!

I guess I'm sort of "new" to this, but what exactly can people do to their steering racks? Run something that has a quicker ratio?

Tech inspector stated that they have caught a few 99+ cars with 90-93 steering racks.

And what would be the advantage of running another year steering rack?

Not saying we should or shouldn't be teching for that -- just honestly curious. I own a '95, so it's no skin off of my back one way or another.

I don't know to be honest. Tech official stated that they have different ratios. Don't know that it is a competitive advantage but certainly it isn't legal within the rules.

That is not possible to do, less running an old subframe as well or welding different mounts on old subframe? They do not even bolt up the same?
What was probably beeing checked was looking for 99 steering racks on older cars, thus 99 subframe in 90-97 car.

Thats just what the tech inspector stated when he was checking out the rack on my 99. Not sure as to the accuracy of his explanation.

Within 90-97, the manual and power racks have different ratios. The power is 15% quicker I think. If you convert the power rack, you are IT illegal. If you put in a manual rack, you are IT legal (and your ham handedness will not be reflected as much as movement in the wheels).

Somebody brought up in another post the question of if a probation comes with the DQ and I never saw the answer. Anybody know?

How is compression ilegally changed?

It's compression ratio in this case. Changing the physical dimensions of the combustion chamber will produce a change. Overboring, decking the head, increasing stroke will all change the ratio to some degree.

Mr Cert24,

I would like to set the record straight.My engine whistled at blinking 9.0-9.1 on 2 cylinders only.I was quite surprised having had my engines whistled in the past with no problems before this.I decided to forego any tear down to argue the point simply because I had a ten hour tow home.I will investigate further and insure that the engine compression is to spec before the next event.

Mr. Motor,

That is clearly not what the tech officials stated to the other top finishers. Nor what several of the drivers observed while standing there as they tested your car. Video will be up shortly of the race for those interested.

Holy [censored] ! Did anyone happen to count the cylinders in that thing?!

Was anything done about that little maneuever at the 2 minute 15 second mark?

It's crap like this that ruins the sport. Hopefully the appropriate penalty was issued.

I wonder what they would have found if they went a little deeper. Also from what i've seen posted, those that are whistled read lower then what they really have.

9.0-9.1 borderline should have passed.
with 9.0 being the spec and the whistler tolerance.

Just to add a little bit of history, 1+ year ago, our club hand their hands on the Whistler and brought it to an event at Willowsprings Raceway. The regional tech tried to check the top finishers. The 2 Christian, mine, Hoover, and Valafar cars were whistled. Hoover's car were close to the limit. Valafar's car blew right at the limit. The 2 Christian cars and mine blew consistently 1 point below the limit (no wonder we got smoked).

Fast forward to this past weekend. The Club apparently dusted off the Whistler and the National Tech crew was out here to help. Mine was the last to be Whistled and so I had plenty of time to stand around and watch. Although a friend of Hoover was standing in front, I did see Hoover blew a number higher than stated. He was still turning the motor when I didn't want to watch anymore and just walked away. What was the final number, I have no idea.

I understand some cars are more well prepped than others. I just wish they are all compliant so we can all have fun racing together. Isn't that the whole point?

You look pretty good in the braking zones Jonathan. You definitely make up most of the gaps there.

Are you willing to share a few unedited full laps from this past weekend or any other? You definitely have a good handle at that track.

It was about 1.0 low. Instead of say 9.5, it read 8.5. Obviously, that was the first time local tech used that equipment and was not quite sure how to operate it fully...

Out of curiosity,

If a driver runs two classes or say runs a double national/regional and is dq'ed on the second day, are they dq'ed from all races, or just that particular one?

9.3 is what I saw, even creeping to 9.4 once. the third cylinder was even double checked. Sorry to invade your personal space while they were running the test, but you were welcome to see all the other car since we have nothing to hide.

I started behind Mr. Motor and gave him absolutely no room to jump the start. (my bumper was literally scuffing his paint at the start) He hopped out of a 4 car draft and went from 7th? to 2nd by the first turn.

Sorry you lost what could have been your 1st national win over something so foolish. Hope your able to get the car sorted out and back to legal spec again so we can really have a true race.

Per the video: Where do we get one of those "push to Pass Buttons" because it appears to come in handy when you screw up a corner and have to pass.

I screw up alot of corners, so ill need alot more Push to pass allowances.

Assuming that the compression accounts for the car's performance and judging by the video, I would say it is enough of an advantage to win regardless of driving style. [Wink]

But seriously, that car looks like it had 10 HP on the camera car.
