Tarmac Rallying Perpetual Thread

Burnouts are bad kids- confirmed that we ran days 4&5 with a mostly 2wd GTR!

The boys discovered a very shagged pump & suspect the damage was done by some rather 'spirited' launches early on.

Did everyone hear the Targa news today? Adelaide is no longer a Targa event however High Country is now a 3 day event with 5 new stages for a total of 270kms.

Back at work, so time for some sau

The week was going so well until Saturday morning. The only issue I had to that point was a leaking end tank on my oil cooler, which I swapped over after the prologue. I had wound the boost back on the Friday night, as Pete had engine problems on the way into Strahan, and then pulled out the next morning.

We took off from the start of Reece Dam and as soon as a grabbed 2nd gear the Alt warning light came on. I turned all the electrics off I could, and watched the battery gauge drop the whole way through the stage. I got out and checked the belt, connections, and fuse links at the end of the stage, but they were all fine. I drove another 2-300m and the car ran out of electricity.

When we were sitting on the side of the road some local photographers that I happened to know drove past, and had jumper leads. We jump started the car, and the alt magically started working again. We caught up to the field at the lunch break, and Damo had a look at the alt to try and diagnose it. But nothing could be fixed in the time we had, so we set off for the next stage Natone. I took off from natone, and the alt light came on (it had been working fine for 2-2.5 hours), I turned everything off again and made it to the end of the stage. I did all the things Damo told me not to do (sprayed brake cleaner into the alt to try and clean it). The car ran out of power just before the next stage.

We kept putting batteries in the car to get back to Strahan, and swapped the alt over. My alt was diagnosed with a faulty regulator. The new alt was less powerful (80a vs 120a), so I had to disconnect the passenger side of the heated windscreen to keep the battery charging for the next day.

I started the next day full of sand in my vagina, and decided to have a good dip on the run home. We got some pretty good times in the wet, I was pretty pleased to finish the wet Strahan stage 3rd outright only 5 secs slower than Vandenburg.

Liam and Larry deserve the result, they earnt it in the wet weather.

Tarmac Gurus,

Would Federal RS-R or Kumho KU36 be an acceptable tyre to use for the touring class of Mountain Motorsport's 'Great Tarmac Rally'?

I've wanted to get into road rallies for a few years but don't have the budget to commit yet and it seems the touring class would be great for me to be able to have a go without having to change my car a lot.

For around $1k budget, what would be the best tyre to go for? I was looking at 235/45r17 or something similar to that size. Nitto NT01 and NT05 seem to be available for around $1k or less too, but I don't know a lot about these tyres.

Thanks fellas.

I've not done GTR, but I have done both Baw Baw and Lake Mountain touring events and in my opinion it won't make any difference what tires you run. You won't be going fast enough to worry. I did all of mine on Pirelli street tyres and they were more than adequate.

That said, how fast you go depends a lot on the pace car. You get a 'liberal' pace car and dry conditions then...

I wasn't too sure how held up you might get, was the pace even slower than a normal hills run you'd do for fun on a weekend?

Also, is the pace car just one of the touring entrants or an official from Mountain Motorsports or similar?

Cheers mate.

Damn, nothing like pulling things apart only a few days before.

Picked up mine from my tuner today. Need to put the passenger seat back in, oil change, swap the wheels over and get it registered tomorrow. Leaving at some ridiculously early hour on Wednesday so hopefully have time to drive a few stages in the Patrol/towcar in the afternoon.

Anyone know of someone in the Mansfield/Melbourne area that could supply and help fit a nismo twin plate clutch tonight (Saturday)? Clutch started slipping after lunch today on the Targa High Country.

Please call 0422 808 999.

Any help much appreciated!

hmm well that didn't all go to plan.

simply put, the tyres were not up to the distance in those temps. this was the better front that we took off before the last stage.

I took 4 Dunlop mediums and decided not to spend another $1k on 2 spares so I just grabbed some 5 year old Federals I had in case of emergency (1 in the car, one on the trailer). The tyre shop were super confident the 4 tyres would be fine. They were wrong.

I noticed the front left had delaminated on the stage after lunch on sunday so changed it for the spare, but since I only had one spare we had to roll through the next 2 stages with mismatched fronts, we lost about 20min in those 2 stages. We managed to stay ahead of 999 back to the base of Buller, Neil and Mark did a super quick change of the other front and we were able to complete the rally; even with the rooted and mismatched fronts we were only 10sec slower up Buller on the last stage than we were on day 1.

The car was awesome for the first 1 3/4 days but we lost the brakes on Sat arvo; the pedal did not work 30% of the time which made it an interesting guessing game. The boys worked most of the night changing and bleeding brakes, and then changing the master cylinder at 5am the next morning to get us back out but it did not sort the problem; it seems to have some sort of air lock in the ABS because it magically gave us more air every time we bled it; we spend the day on Sunday bleeding it after every stage. Also had a minor electrical issue which returned us to wastegate boost on an ad-hoc basis, a fuel pressure issue (which luckily was only a problem at idle) and a diff that was shaking itself apart.

Can't believe how good these cars feel when they are behaving though, it was beautiful and totally predictable.

Overall the event was excellent fun, the roads are very (too?) fast with plenty of time over 6,000rpm in top gear, although we never got to the redline in top. Some tighter stages but I enjoyed the open stuff.

Kel is an awesome navigator and didn't give a wrong call all weekend; as pretty much a rookie I was lucky to have her calling the shots. And not just good calling, also knowledge of the rules and logistics that kept us on track and got us to a medal at the end despite the car issues.

And finally a huge thanks to Neil and Mark, they worked their arses off to keep the car running and were always in the right place when we needed them. Plenty of experience with these cars mean they did everything quick, right and no fuss.

    • Thanks for all the replies! I also wanted to ask if wheels that were fitted on Ford Falcons would fit the 350GTs as well? In the area I'm at there aren't that many options for secondhand wheels and new ones here are way out of my budget. From what I've seen, most of the wheels that are available that were fitted on Ford Falcons have an offset of +33 to +36, with a centre bore of 70.5mm whereas the stock 350GT's ones are 66mm, can't seem to find any hubcentric rings that fit that difference though. 
    • 215/45/18 tyres are probably a little on the low side compared to the factory tyre, it should be closer to a 245/45/19, which will get you about an extra 11mm of height, and should make you speedo read a bit closer to reality. 245/45/19s will be a bit too far the other way and you risk a speeding ticket as your speedo might read slower than your actual speed.  245/40/19s would be correct if you are going to 19in rims, they will give you a similar total diameter to the 245/45/18 tyres.  
    • That's something I forgot to put in my list. The aggressive anti-squat in R32 is a f**king menace. I still need to decide if I'm going to drag the subframe out of my car and weld in the GKTech corrector kit. The main reason to dither is the need to switch to spherical joints in the lower arm to account for the twist induced in the rear pivot caused by lowering the front pivot. And yes...we do put better subframes in R32s, and I wish I'd gotten an S14 one instead of an A31 when I did the "take off and nuke it from orbit" HICAS delete all those years ago.
    • I have been looking at some setting on the alarms for the Q60 and what buttons do and so and also been looking for details on the alarm in my V37 which is a standard issue with the car. settings like window roll up and a few others seem to not work at all. i cant seem to find exact info on V37 alarms so Q60 is all i can really go off i have not tried 400Z alarm settings or info yet so that will be next. any one got like a sheet of info on the alarm system in the V37 as all my documents are in japanese but i thought the system would basically be like standard through similar models? 
    • I had a fuel smell coming from the drivers rear and pulled the tank out to inspect where it was coming from, turns out the breather hose from the tank to the filler neck was perished. I’m going to Japan next week and I’ll grab it while I’m there  pulled the oil tank apart and started cleaning this crap out of it, some brake cleaner and rags got it looking new again
