I was think of getting a R34 GTT but since I have seen you racing around the track in that GTR im going to buy a R33 GTR now

She looked sweet as and went like no tomorrow

Thanks for that.

Your right tho - it goes like the clappers and with fairly simple mods.

I was just trying out some new camber settings (which I'm still not sure of)

Just waiting for my new track wheels to arrive - should look the biz then.

Should be going out on Saturday for the sprints - so hopefully will see you guys out there again.

EVO Cam,

Those QR Sprint days are timed by hand. There is a guy in the tower who clicks a button when a car goes past. So if he is a bit slow or quick, presto you have a great lap time. He hands out timing sheets with 3 decimal places but its all smoke and mirrors.

Thats why the records above are only from my electronic timing system. It is internally accurate to 1/1000th of a second for each and every lap.

Paul

The loop does not detect your car when it goes past unless you have a transponder in your car. These are used for race events such as the V8 Super Cars and cost about $550 each.

What the guy in the timing room is doing is pressing a button to simulate the read of a transponder.

When he gives out a timing sheet with several decimal places on it he is decieving you. Let me explain, see 1:03.8 (1/10th sec), 1:03.83 (1/100th sec), 1:03.835 (1/1000th sec). There is no way that someone pressing a button is repeatably accurate to any of these. If he gave a time of 1:03.8 (+/-0.5sec) that would be more like it, but its still generous.

What you have to factor in is that he is pressing that button not only for one car over 5 laps, but for a whole grid of cars over several hours. So errors are made and sometimes in the order of seconds. For example, the Porsche club "wash" the data before making it official for their competition by deleting any entries that look suspect.

My timing system is based on a hard real time microcontroller that captures a time stamp with an infrared sensor across the track at the start finish line. The internal timer is accurate to 1/1000th sec. This accuracy remains for every time all day.

To get your time in the "Time Attack" record you have to come to one of our track days. The next one is August 30 and the one after that is November 30. Currently our days are only during the week, although I may be timing weekend events in the future.

I hope that answers your question. If anything is still unclear please post futher questions.

Paul

Paul,

As an indication of just how accurate the "push the button" method can be, I have recorded a 56.7 second run on the sprint circuit. Whilst I would love to claim the time (and probably will when bragging to mates) I would hold a number of track records if it were true

Our next track day is on Tuesday August 30.

The track is in Ipswich.

From the GC you would probably come up the highway and take the Logan motorway, then head out to Ipswich and take the Warwick exit. After about 10mins or so there is a bid sign on the right that says Queensland Raceway. Head down there to the end and you will find the track.

Otherwise you could meet up with someone heading out there on the day and just follow them there. We have guys coming from all over. I am pretty sure a few are coming up from the Coast.

  • 4 weeks later...

Hi Guys,

I Would Love to come to the track day, can you tell me how much its gonna cost me to enter, and what time it will start and finish..... and can un registered cars be allowed to run on the track ?

with a SAU membership can i allpy fora cams licence?

cheers

Hey Mate,

The track day costs $110. We arrive at 7:30am to setup and are on the track from 8:30 to 12:30. Maximum of 5 groups each with 9 cars. So you get lots of laps.

The next track day is on Aug 30. There are only a couple of spots left now so if you want to come PM me your email address ASAP and I'll get you all the details and onto the mailing list.

Also you do not require a CAMS licence as we run the AASA insurance.

The car does not need to be registered. It does need to be safe.

Hope to see you out there.

Paul

I'm going for at least 1:10.00 for the clubman track at the Aug 30 track day now that I've got a few minor suspension mods.

I'm hoping for 1:09 but I still got a really old crap set of 245 ziex falken tyres to run on.

Anyone else planning on beating their best time? If so what are you aiming for?

Its getting close. . . . . . can't wait.

Not sure what times I will be running, would be real happy with a low 1:03 or maybe sneak into a 1:02 on the clubman and a flat minute or under on the sprint. That would keep me smiling for weeks :huh:

Damm rain, I only missed my goal of 1:09:00 by 12 seconds or so :(

Never had a real intrest in getting a good time, just happy to drift - as those behind me may have noted as I spun out for the 4 time at the end of the main straight (thats my excuse anyway!).

Glad I did not take off the 2 week old front bar when I ended up in the kitty litter!

Had a great day though, thanks again Tim and paul.

    • GCG is a good company, they're a major distributor for Garrett in Japan as well.
    • Nah, OEM washer bottle and brake fluid reservoirs are fine I don't know what it is with the plastic that Mazda used, some plastics, like the washer bottle and brake fluid res are fine, and still look new after 20 years use, where as the coolant expansion tank, and PS reservoir, that I replaced with new OEM items when I first got the car, turned yellow and started getting brittle a few years later If the dirty yellow stained plastics didn't trigger me there wouldn't be an issue, but they did, much like the battery bracket....... Meh As for going back to work full time to support car stuff, nope, why, because I own a Mazda NC MX5, not a Nissan R series Skyline 🤣
    • I've never heard of CJ-motor, so can't advise you on them. I'd just go straight to GCG for a GCG highflow though. Seems no point to use a middleman. I'm somewhat surprised that the price on the CJ site is lower than the GCG retail price. Even though CJ would get a discount of some sort, you would hardly expect them to give up so much margin. Maybe the price is out of date? Having said that "I'd go to GCG"...when I did my highflow, I went to Hypergear. I did this https://hypergearturbos.com/product/rb25dethighflow/#tab-dyno-results with the R34 OP6 450HP profile. With the BB centre (extra $400) and intially with the standard boost actuator, but I eventually got him to send me the high pressure one when I got to the point of being able to actually use it. Ends up costing the same sort of money as the GCG highflow, but this is, of course, the turbo that I KNOW has a shorter length core and so moves the comp cover rearwards. The GCG apparently doesn't do that. My mechanic also swears by the GCG highflow, given that we have another turbo rebuilder who does something essentialy the same as theirs, using Garrett wheels. He says it stands up at really low revs and makes good power. I haven't pushed my HG highflow past ~240-250rwkW yet (should have a little more in it, but unclear how much) and it does have a fairly gentle boost ramp. OK, it's much better now that I have gotten my boost controller tuned up on it.  A lot of my earlier unhappiness was because I couldn't keep the wastegate flap as closed as it needed to be (including some mechanical issues). I'd still prefer it to boost up nearly as quickly as the stocker, and it certainly a bit slower than that. So maybe the GCG one is worth the first look (for you).
    • Ok thanks 🙂 I will higly consider this. Any "known" company for a good reviews and experience to send that off? Is that CJ-motor good one? Or go straight to GCG site? I need to use VPN to even find some of those "shops" let alone access them 🙂 
    • You can literally put in as much WMI as it takes to quench the combustion totally (and then back it off a little, obviously), and it will keep making more and more power. The power comes from the cooling effect of the water (and the meth) and the extra fuel (the meth, which also has massive octane). It is effectively exactly like running E85. One might be slightly better than the other, but they are damn close. But with either you can lean on the boost or the timing (or both) waaaay more than with just petrol and the results are similar. Here's the first thing I googled for an anecdotal bit of evidence. Can't access the attachment without being a gold member, but it is there for the getting if able to, or searched up elsewise perhaps. https://www.hpacademy.com/forum/general-tuning-discussion/show/wmi-vs-e85/
