Gdya guys I've been playing around with spark timing. Is it ever acceptable for a car to ping, eg: instead of slapping it in 5th at 2g and stomping it I decided to eliminate wind noise etc and pull up the handbrake and let the clutch out on full load. I sarted using this as a test for pinging but thfound that even very close to stock timing (15 degrees) the car wud still ping.

Is this an unfair test? how far can I advance the timing safely? 5 degrees?

cheers

stock they run about 15degress BTDC base timing, mines at around 20 and no pinging and thats even running vortex 95 when im lazy...

my brothers on the other hand has maxed his out, i havent stuck a timing gauge on it but i would assume it has atleast 25degrees of base timing. Still no pinging on that either. It depends on your climate and fuel quality.

ah ok kool, umm whats the best way to test for pinging? basically i chuck it in 5th at about 2g and stomp it. but the thing is the vibration from the car (pulling a high gear) genrally drowns others sounds out, and by the time the vibration seases at about 2- 2.5 grand it doesnt ping. is that ok?

Just wind up all your windows so you can hear just the engine as much as possible then load it up in lower rpms and rev it out like you're doing, 5th is abit overkill, 2nd or 3rd should be fine since its n/a and wont rev out too quick haha.

If you are really worried go to any performance place and ask them to do a dyno power reading, and while they're doing the run stick your head in the engine bay and listen out for it. Probabaly cost you $100 for the run

      It was a great, but typical track day, and some VB was ingested at the night time debrief 🤪

      And so, to round this out, I couldn't be happier to confirm @MBS206 has decided to buy the car. He drove down from sunny QLD with a trailer last week and it is off to its new home today. I'll let Matt confirm on next steps but I understand broadly that the plan is to leave it pretty much as is, and just get some quality wheel time with a nicely balanced car that is pretty much track ready. There are a few a jobs still to be done first but nothing too major and I think its a very smart buy Dinner last night at the Paragon with a round of VBs (mostly) for Neil

      Well, 50 pages and the end of a chapter for this car. We took it out for a shakedown at Wakie yesterday, and everything went well. There were a couple of niggles: - Oil cooler fitting leak - tightened, cleaned, stopped leaking - Radiator cap overflow fitting was leaking....Mark called it, the overflow fitting was threaded in and not tight....tightened, tested and held pressure - Small oil leak at the rear of the block, probably the turbo oil feed - too hot to get at it comfortably but probably just needs to be nipped up - leak at the driver's side rear brake line where it meets the hardline. Fitting wasn't loose, so Matt backed it off and back on, no further leaks - there's also a leak somewhere on the top of the fuel tank, maybe that cross over fuel line - that was has been left to fix when its on a hoist Otherwise than those niggles the car went great, turned great and stopped great so it was a very successful day out. I'm always really nervous when a car first hits the track after a long break, especially with a brand new engine as well but it was great. VID-20251011-WA0007.mp4  Big thanks to @The Bogan who dropped by and helped out, @MBS206 and my nephew Lachlan the apprentice.  Neil's wife Mel also surprised the hell out of all of us by dropping by; she's up in Tamworth these days but was travelling to Melbourne so had plausible deniability for turning up at the garage, it was great to see her but also obviously a bit sad all round.
