This is from the twin spark cup regulations:

You probably have to run that, true. But then your current suspension won't allow you to run for points there either. But I think you still can participate. I'm from QLD though, and sadly we don't have the number for TS cup. You better check with their orgs, I'm sure some are here in other thread/sections.

Which ensure an extra $5,000 to spend if coil overs are $3,000 and I need a set of 16s and tyres. Most 156 track car threads I have read are using 17s and even 18s. I am guessing the 17s on the 156 were optional and I think the gta came with 18s. But rules are rules.

Anyone have any tips for taking out the sound deadening. I bought a can that freezes electrical circuits from jay car but it doesnt make any difference as some youtube vids claim. I have used a blunt chisel before but that takes forever and leaves residue. I bought a sharp chisel this time but it is stripping the paint of as well so I will may just do it and paint over it. Ideally it would be a 40 degree day so it heats up but not waiting to summer. Would a hair dryer make any difference?

Dry ice

Buy a couple of bags, place it on the floor, chip it all up, works a treat (did for me)
Should be able to get dry ice from your local fisho shop as they use it in esky’s (chilly bins, etc)
Make sure to leave the doors open and ventilate


Heat just makes it sticky and leaves residue
Dry ice takes it off and leaves behind a perfect (primed/painted) surface

Thanks. Is that safe to go near the wires as I haven't taken out the main wiring looms going down the side of the car?

Yes, as long as you keep the chisel away from the wires, and don't try to bend the wires when frozen (snap).

Thanks. I will give it a shot next weekend as removing the airbags took longer than expected. How long does it take for the wires to come back to room temp? I am guessing leave it over night?

Are these yellow cables all for the air bags? I cut of the connector that was part of the air bag but it seems to keep going to the left that may go into the door? All the other yellow cabling that is at the bottom of the pic came from the airbags from the seats.

*Note make sure you disconnected the battery terminals before taking out airbags.

What is the silver box that all the yellow cables are going into on the bottom rigt side of the pic? Is this some sort of ecu?

What about taking out the heater? Is there a point of keeping it? What about for 24h racing where conditions might need it for defogging the window? Or is that part of the air con system? If I want air coming into the cabin without the air con on, is the heater part of that system?

Yes, in the 156 all the yellow sheathed cables are airbag related. The silver box you refer to is the Airbag ECU.

I'd keep the heater, as it works in conjunction with the A/C to defog. Besides, if you end up doing a 24hr or something similar in the middle of winter you'll curse yourself for removing it.

Hey Alfatango, I look forward to seeing you on the track – hopefully in the near future what with lockdowns and everything.

I was just catching up on this thread and wanted to acknowledge Colin's suggestion to limit your revs. Over the last 2 or 3 years I have witnessed the demise of roughly 10 TS's, mostly bottom end failures, in my own case a broken valve spring (if I remember correctly).
Not entirely surprising given their age, I guess. One Alfa specialist has suggested, as Colin said, that sustained revs at the limiter are to be avoided – I guess this is a track specific issue – holding 2nd gear at Winton short track turns 5, 6 and 7? – I have'nt driven there for a while!

Watching Twins Spark Cup cars in action in the UK I am blown away by the sustained high revs, but I'm guessing that these are purpose built engines, within the competition guidlines?

Food for thought!

Thanks Bazz. Can I remove the airbag ecu now that all air bags have been removed?

Thanks Al. Are you using a limiter to stop the revs at a certain rev range? If so, how does it work. At the moment my goal is to get to a start line rather than squeeze the last tenth out of a lap time.

I feel sorry for Neil as the lock downs keep cancelling the events.

Hi Alfatango, no I am not using a rev limiter, I had not considered anything to supplement the factory limiter until Colin suggested it in this thread.
I sprint my son's 147 very occasionally and am happy to reside at the slowest end of the lap times – a bit like you I'm not out there to challenge for the fastest lap time, my objective is to have a fun day and drive the car home after the event.  :)
The car is on its second engine after an engine failure at Winton whilst my son was driving, and I don't want to pay for number 3!
My son on the other hand is a little more exuberant (as you are when you're 22), and I reckon that a device to limit the revs to about 6,100 is a really good idea.
Colin, maybe you could elaborate on the best way to do this?

The other way to go about this is to go for it, and to accept that you might need to replace the engine at some stage. Imlachs wreckers have TS cars coming and going all the time and you can buy a complete second hand engine for $240 if you know what you are doing (I don't)  ;D It is racing after all...

Cheers,
Al.
