Had this happen to me on tuesday

181904_1283235217183_1719195671_507243_6217350_n.jpg

Any thoughts?

I have been running 4 deg camber for last 5 track days, last 5 track days I have been using 2nd hand pcup slicks.

On tuesday I used new slicks and this happened at the end of 3rd session, (about 15 mins on track)

Tyre pressue was 37 after 1st session.. I then dropped to 28... So would have been a bit over 30 when this happened.

There were no lockups and the wheel didnt hit any curbs.

Thanks for any help.

Drew, some reckon that with the weight of our car we should be more towards 35 psi, I normally run around 35 psi but experiemented with 31 hot on tuesday. My tyres look fine and wear is good and even, with a fine ripple over the entire surface. did you check any temps on the day?

do you have any suspenison components rubbing?

damage during mounting i suppose is the only other thing I can think of.

either way mate, sorry to see your day ended like this, you were putting out some impressive times.

I recall the WRS guy at the track said it didnt think it was a puncture (at least not from trauma to the tread) but I guess with the way it is chewed up how could he tell. have you had time to give it a good going over Drew?

Nah, didnt check tyre temps on the day.. I will be sure to do this in the future though.

No components were rubbing on the tyre from what I could see.

The guys from WRS have the tyre now and will give it a good look over

Yeah its a shame this happened, but then I dont think I would have got much more track time in with the rain soon after.

How did you end up going with times? get back out there later in the arvo?

no, left before lunch. no better times later in the day. was pretty happy with the time we got considering the car was a handful (oversteer) after we changed the roll bar settings. a few tweaks hopefully will sort that out for next time out.

    • You know how your car rolled through a fence in your last jacking escapade? Scissor jacks increase the likely hood of that sort of thing happening immensely!
    • http://calfinn.com.au/product/1500kg-standard-trolley-jack-cj-2t-c/1500kg-standard-trolley-jack-cj-2t-c   I have this and fits under a S3 33 GTR with no issues. Purchased in 2009 and not one issue. It was $950 back then. Not cheap but something so important isn’t worth cheaping out on.
    • Just trying to get my head around this. At 5psi of boost, you turn on your wmi pump, and then you're using a 3000cc injector, to allow flow upto the actual engine, where you have your 6x200cc injectors and a 500cc injector. If the above is correct, what advantage are you obtaining by having the 3000cc injector blocking flow, is this just incase a line breaks between that injector and the motor you can stop flow immediately? Or are the 6x200cc and 500cc less injectors and just spray nozzle?
    • Welcome! New member myself, but I had an R33 back in 2002. Best advice I could give, based on my experience: if you're running the factory turbo, be very conservative with boost. I made the mistake of just fiddling around with the boost controller and cranking the boost for fun, and the end result was my intake pipes popping off frequently from the constant deluge of oil that was being blown into the recirc by the stressed-out turbo, which itself was siphoning oil from the engine and farting it out both sides of its centre bearing (or something to that effect). If I could do it all again, I would have gotten a new turbo and had a tune dialled in professionally and then just left it alone! Funny you mention the metal shavings in the gearbox, as I had the same thing - the probe plug (magnetic drain plug, essentially) would come out caked with shavings. At least it was doing its job. Not sure if that's just sacrificial wear and part of the deal, or if my gearbox was shagged, but I wasn't abusing it. Enjoy the R33 - they're a dying breed, and if they weren't $35k+ on CarSales in Queensland, I might have picked up one of those again, instead of the 370GT I own now (though I'm loving the 370GT, that big 3.7L V6 just hits different).
    • Howdy folks. I owned an R33 back in 2002, which was thoroughly beyond my capacity (financially speaking) to maintain/insure, so we parted ways in 2004. Fast forward 21 years (to literally yesterday, in fact) and I'm now the proud owner of a 2007 V36 370GT. I'm happily surprised by how much power the VQ37VHR makes, compared to the RB25DET, considering the latter is turbocharged. I had planned to add a turbo at some point but I'm on the fence about whether I'll even need it (though I do love the sudden onset of extra torque). Any other 370GT owners around the traps, I'd love to hear about your experiences with this car (good and bad).
