Backfiring is usually from restarted timing. loosen the screws on your crank angle sensor and turn it full clock wise if it pings wind it back a tad.

Also check that your igniter is earthing properly, my car was running retarded timing even with CAS turned fully clock wise until I ran a separate earth wire too my igniter.

You have now repeated that twice. Do you feel that you should be offering this advice knowing the consequences of what you are suggesting?

I havent had a chance to order new coilpacks yet. funds have been tight!(despite working for a banke :D so car still missfires when you rev over 4500-5000. I redid all the solder connections in my AFM about a month ago and have replaced my O2 sensor im still stuggling to get 300km to a tank.

When baking off the gas to change gears im getting alot of backfire. especially when downshifting/engine breaking. Ive been reading around heaps and am wondering how big an impact my atmosphere blowoff has on fuel economy (despite being illegal id hate to lose the "ptsuuuu" sound of my blowoff) ? In the last week ive started to get exhaust soot all over my rear bar. This hasnt been a problem before??? whats going on things seem to be

      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.
