Hi guys,

Got my confirmation of entry from the Mini Car Club of NSW yesterday.

This is going to be my first such event, and have a few questions:

1) Who else from here will be competing?
2) Who supplies the numbers for this event?
3) What else am I going to need for scrutineering? (I'm in Type 2 Class B)

I have BD Roll bar (not previously CAMS certified), mounted fire extinguisher, 6 point harness, and secondary bonnet restraint.

All advice gratefully received.

Matt (& Lara, the Supersprint virgin!)

1) NFI, but Matilda will be running the turbo race car
2) You do.
3) Clothing......long sleeve cotton neck to ankle, leather shoes and full face helmet with visor and gloves if running open top.

Have fun!

1) Me, no doubt most of the MX5 championship registrants...
2) You do, and make sure they are close to spec. (ie white background, black numbers and big!)
3) As for what you will need for scrutineering:

- Your L2S license and club license (don't forgot those!)
- one-piece fire resistant overalls or suit.
- Helmet
- Triangle to mark battery position.
- Brake lights are working
- Secondary throttle return spring. (They can be pedantic, and they may let you get away without one. Note: this is inaddition of the intertwined two your car already has... They are easy to fit to MX5's)
- Extinguisher
- No oil / fuel leaks

Hope that helps. See ya on the day.

Thanks for the responses guys.

Have LS2 Licence and club licence
Have suit and helmet.
Will need to buy some contact to make a battery position triangle
- Seeing as my car is blue, should I have a blue triangle inside a larger white triangle?
Brake lights working (this is my daily road registered driver as well)
Have extinguisher
Have secondary bonnet restraint

Secondary throttle return spring? Anyone got a photo and an indication as what is required for the MX5?

Going to have to make up numbers. Anyone got a recommendation as how to do this? My father and I will be swapping in and out of the car all day and driving the same car with different numbers, ie 59 and 159. I'd like to get some magnetic white board, like the MX5 Club has, and put the 5 and 9 on their permanently and keep some race tape to make the removeable 1.

Does anyone know where I can get the magnetic stuff the Club uses?

Thanks!

Matt

Yep that's right, just a white background and then an inner blue filled triangle.

I got mine done at a sign making place. But, to be honest, you could do it a lot cheaper by getting some white cardboard, some sticker numbers (or cut em yourself) and either laminate or contact and then use race tape to hold against your doors. Black tape can be used for your number 1.

Hi Matt,

I have my old supersprint numbers you can have, well the magnetic background. You will need to get stick on numbers, but they are cheap I have 225 on them. and the triangle that will work for you.

You can get numbers at Revolution.

PM me.

And watch out for the faded orange lancer, bloody idiot driving that thing!

It's basically just a spring that you put ont the actual throttle turny bit in the engine bay that opens the butterfly on the intake.

The spring needs to offer resistance AGAINST it opening in case the fatcory one busts. That way, your throttle won't be stuck open.

Just needs to be a small spring from the turny bit to the the intake manifold.

Not required on fuel injected engines I believe - certainly the GM has never had one, nor been queried about it.

It's pretty hit and miss, I saw a few mx5's (inc SP)get pulled up on it.. and talk their way out of it . They like to target something every year... last season it was throttle return springs and then mx5 rollbar height.

Slightly off topic, but then again what post in almost any thread on this forum isn't slightly off topic.

Getting a wheel alignment tomorrow.

Search on here didn't find anything useful for a NA8 on 15\" rims.

Couldn't use a search function on Miata.net

Anyone know where I can find good wheel alignment setting for a NA8 on 15\" rims?

Matt

WOOHOO!

3rd in Class and 8th in Type, but 45th overall.

Not bad considering Team Guyder Racing (TGR) couldn't agree on tyre pressure and it wasn't until the last 2 runs that we starting actually getting grip from our new semi slicks once the tyre pressure was lowered. A third of a second outside my previous PB, but good enough for third in Class. I was going to have to beat my previous PB by almost half a second if I was going to knock Mike Hicks out of second spot.

Over the course of the day, I had great fun chasing a Mini Cooper S. Don't know what it had under the bonnet, but JEEZ in a straight line it had \"get up and go\". Also had wonderful watching a well sponsored Monaro struggling to even keep up with me.

Overall the event just reminded me just how well the MX5 Club track days are organised.

Much thanks to Mike for his assistance on the day!

Matt

Congratulations Matt, well done for the Club as well.

What pressures did you end up running?

Great job by the MX 5 Club.
Turbo Girl did a great 1:11:55
The CRX in my class was having boost problems thus giving me a chance, Sam would be 2 to 3 seconds faster, thanks Sam.
I'm going slower than 2 girls, Matilda ok, Turbo girl, we will see what happens at round 4.
I may have to find a front splitter, big rear wing, loose passenger seat, trailer, tow car, etc etc etc

The NA 1600cc engine only had one throttle spring and should have a secondary one fitted.

All 1800 engines have a second spring already fitted (both concentrically wound) so shouldn't need another to be fitted.

Great time TG - when can i have a drive
