thanks mate. yeop thats me ....they turned my tired ramblings into something decent which was nice 😁

I shouldve just said refer to SAU for said history ... its pretty much alot on here haha

I thought you were remarkably coherent and made the most of the inane questions you were given to work with. I love the thumbnail shot with dust blowing up from the diffuser.

I got one clip of the car from WTAC this year. It sounds amazing coming down the straight. Though the potato phone recording does not quite do it justice.

 

It was nice to meet you in person @bcozican! I'm the guy in the explorer hat who came up during the pit walk on Saturday.

Much appreciated that you went out again in the afternoon session. It's a shame not all the teams do.

Hope it all worked out well for you and that you can make it again next year!

Hey!  Thanks for that it great to meet you sorry wasnt for long was hetic 

Hope you enjoyed WTAC!

Yeah we upped the rev limit in 5th gear and just wound that out rather than a shorter change to 6th and back to 5th again around T1 and wow it was screaming its little RB tatas off 😄 

That arvo session I had to go out! I hadnt had a proper run since the morning session on Friday so was my only chance to go full send

 

Theres a reason the top teams dont go out because the track was absolutely junk!  I had to have a crack and my 1.31.1 prob wouldve been a low 1.30 in a morning session in fact I was up 1.2 sec on my 1.31.6 coming into T8 even then but the tyres literally went to mush

Still managed a PB ad 6th in Open class not horrible for a guy that gets about 10 laps a year on SMP and only booked 3 hot laps

The car is very good now

But wow it was a hetic WTAC might do a run down just got home yesterday from 4 day drive back to Perth

Hah, all good! I just wanted to say hello.

Fair enough if the conditions aren't great. But as a spectator the more I get to see the cars on track the better. It was really good, but will probably come two days next year just to be able to see it all.

I'm all for the new rev limiter! After the V10 Rodin Sintura, the high revving RBs like yours were the best sounding cars out that weekend.

[bcozican]

OK WTAC '24 adventures - dont know if anyone wants to hear it past whats been put out already but hey I'll put some of it out anyway and try give some insight

 

Summary : end result - 6th open class and 1.31.1 lap

 

How'd we get that

 

Following the above after Aus Time Attack at Winton and driving the car up to Sydney to store the rb2.8 went in so got to fly over to Sydney the Monday before the event

 

 

The car was with Greg at Sydney Composites workshop - we got straight to work that arvo changing out the front wheel bearings as they flog out allll the time.

 

A new bonnet was being made and my goodness its nice !  also new bigger canards were put on as I was the first one to trial the new canards and after testing from others bigger basically proved to be better rather than my initial cut down version.

 

We also did ride height changes and setup was there till 1am Wed morning but got it all done

 

 

A big focus this year was to get me some seat time on SMP - laps for me = good so has an extra prac Wed morning to roll around so up at 6am to track

 

 

Basically 2 quick sessions and 3 'hot laps' we quickly worked out that the custom red / golds  MCA's I had in werent valved strong enough to hold up all the new aero at these speeds, we suspected at Winton but were hoping... but alas nope. Also the tyres I had on from Winton were gone and just down right dangerous haha

 

So... some appropriately valved MCA golds were sources from Canberra and driven up straight to the track for me to borrow and retro fitted with my current stuff and some better used tyres put on from Xtreme.

 

 

Got into the arvo where I had to take more prac spot so took it - we got 2 x goes at a lap but the setup was wrong and was porposing like crazy so aborted each one but we got it sorted correctly after but didnt get to go out again

 

WTAC official prac Thurs

 

Did 3 sessions of 1 lap each time no power - suspension better few tweeks here and there and got to get a little bit of a groove back all seemed OK

 

We found the car getting back to some understeer because we still had the old rear suspension in and it couldnt handle the aero load but had no options so had to work around it ... it ended up scraping the rear diffuser that sits quite away off the ground that how much it was !

 

WTAC - Competition day 1

 

 

Morning Session - usually the best - wound it up had a crack was good but safe and not the max from a push p.o.v 1.31.6

 

The wind then picked up as did temp went out just for a lap on no power for second session did a solid 1.33 totally sat out the last session as no point due to track conditions

 

WTAC - Competition day 2

 

Morning session - full send !  - ran it hard down the front straight as I got to T1 turn in car faulted and switched off - tried to do another lap after resetting tyre pressures and fuel but was not working properly and got blocked and then had red flag anyway haha - bad

 

Long story short - the balancer had gone and as well took the DBW with it

 

 

Organized chaos ensued - between my team - Dahtones and Herman and just about everyone else we got everything needed and a new 1500 ATI put on - luckily thee was a Bosch motorsport stand in trader ally and they let us take the DBW they had on display to put on my car !  legends

 

So at this point we've only done 1 real lap , missed the good session in the morning missed session 2

 

Pit walk was upon us and is always so busy but great and met @soviet_merlin and others we also try to get as many kids in the car for fun and photos as possible + meet people

 

 

Session  3 - last one - wind was up, track was horrible didn't matter had to go - launched it as good a I could. We changed setup to leave the car in 5th gear into front straight so I didnt have to change down and worked well just held it flat max powas and max rpm - 282 kmph and 217kph around T1 (this has to improve alot )was up 1.2 secs into T8 despite mistakes and as previously said tyres just started going to mush - I couldnt get it around T8 properly lost most of my time picked more up with last 3 corners ended up 5.5 tenths up on previous good lap for new PB but missed out on top 5 by 6 tenths

Still not my best lap

I shouldve had it to make top 5 but didnt... thats racing

 

 

A positive takeaway from an effing tough go at it this year - netting only 2 x hotlaps is both my 1.31 laps combined optimally gave a 1.285 - now I know I'll never be perfect but with a 2.6 sec difference - that means its there it just comes down to consistency to bring that down into an achievable 1.29ish

 

Our best endeavors to have good seat time and a well sorted car illuded us this year but still got it done as best we could

 

Good mate made me take a pit pic in front of the car which I look at now and is good as you just dont know I might not be back, or I might !

 

 

And then after watching the wild Top 5 shoot out you get to pack up starting at 9pm so pack it all up properly for long trip home

 

We had a sleep and then yeop ... a near 4 day drive back to Perth. Look I dont actually mind the drive - its not great but its not horrible - but the toll it takes on you after or before competition isnt optimal and neither is the time it takes to do - maybe another option but they are few and expensive

I tell you what im basically an international and would be ALOT easier to compete at WTAC if I lived anyway but W.A 😆

 

All in all hard work, solid result on paper but even if I was still 6th I would've like to at least be in the 1.30s and as close as I was and maybe due to circumstance it still says a 1.31 - which isnt sh*t just not the best .... the W.A crew that comes with me is awesome, im appreciative of getting to work with some of the best on top of that with Brad and some help from the pro drivers, Xtreme and others

 

So back home back to it - full set of MCA golds going in now which was on the cards anyway and a new 'proper' race radiator to keep it cooler

 

See what comes up next to race at or in ... that I dont know

Cracker read mate!

Would be nice to meet you soon, probably when the kids are a bit older and I'll take them along to see the world's fastest 4 door skyline 

[robbo_rb180]

Great write up. Always good to record everything to look back in the future and reminisce.

How good is the motorsport community with helping out when needed. 

Should be pretty proud of the result you achieved for the little amount of laps you've done there. Also good you have the drive to do better too ,I'm sure a 1.29 will happen next year. 

You thought about a front end upgrade? New upright and arms with better geometry also allow a better bearing your not replacing every time.

yeop wont be doing this forever prob so why not

100% everyones always been good but going back this year was different and more interaction and def more support

Def thought about changing uprights etc waiting for @Komdotkomto sort out whats needed for those and do the r & d haha  but yeah hard thing for gtst nothing direct fit as all made for GTR which is slightly diff but moving to the r35 gtr bearing will be big improvement - its just budget allocation as its a $10K to $30K exercise dependent on how mild or wild you go and seems something always comes up - ontop of the crazy travel / racing

Awesome effort and result, well done. I understand you wanting to get that 1.30 but the reality is this is a super quick car already with road cars being in the mind 40s, its hard to realise how much is required to go that much faster!

The other thing is, having done Targa a few times from NSW, the cost and effort to travel that far to a track and city you don't know, and then deal with things not going to plan, that is a huge extra effort on top of everything.

And once you've got all that sorted you need to drive it too!

Anyway, well done for taking on such a big adventure, I hope you enjoyed it among all the hectic pace and pressure

Thanks... yeop I think anyone thats had to compete or travel more than the usual home track situation gets it and prob even those that havent yet had to do it ... its just harder and costs more fullstop

As one goes through this, prob like yourself, you gain and appreciation of effort - almost regardless of the result - but the result can add to it on top

This year I did enjoy it alot more even though it was harder ...which is actually good!

I'm still waiting for the bearings from Jesse Streeter so haven't fitted them yet. King pins don't fit though, if you're thinking about doing it get the king pins now because the new stock seems to be 3x the price. I got one from Kudos and one off ebay from JP

40022-60U05.

 

If you get them from NZ get him to mark the value down, I got touched for $2k in duty and gst

[bcozican]

Recently did the Perth Festival of Speed - and basically what we thought might be an average event turned out to be absolutely awesome they bought Mad Mike and Xtreme over and was good to see Perth get, support and produce something so good - 24,000 people in two days 

 

 

It was nice to have it close to home for once yet have my whole crew there to run the car properly

 

 

Xtreme got the tin top laps record with 51.57 

 

I hadnt done a hot lap on the home track for 20 months and finally everything clicked and dropped 4 secs off PB and did a 53.29 which is 3rd fastest tin top ever around that track. only 1.3 tenths behind 2nd so should eat that up soon... can I get Xtremes time - its not out of the question

 

Alll the blaa blaa's in the world but if I can replicate even close to that situation on other tracks will be able to make an impact

 

 

We got asked to do the hill climb to put on a show which in reality is just using some chicanes and the short track at barbs but good fun... launch control was put in and won the Pro class in that also.

 

 

Car needs some attention after being on it around Australia for last few months moreso the carbon underbody work and just a run through and clean up everything else seems to have held up good enough. Would like ,to take some weight out but that requires alot of effort 😁

 

Also waiting on new rules for WTAC and have some decisions to be made there and prob some minor modifications to suit pending class changes. Will see...

 

Divided on whether to go hard for one more year or chill out re: events this coming year prob more on the go hard and see if I can get improvements in times. If I didnt have so travel so far it would be less of an issue but I do so hmmm...

 

Also because build thread - gone to flappy paddles and a gearing change with a drop gear. It was becoming apparent that there were situations where I really needed to be hanging onto the wheel with both hands yet had to change gears and was getting a little sketchy and / or I just didnt change gears and delt with it and also 5th gear at 10,000 rpm is 290 kmph so I havent been using 6th as did 282 at WTAC and 274 in Perth drop gear will change to 6th being 300 at 10,000 rpm should also get a touch more acceleration speed

That's a solid update mate, well done at WA FOS.

You may already know this, but the actuators on the paddle shift are a service item and are sadly not that reliable. As I understand it they collect water from the compressor (condensation) which then rusts the bores/pistons in the actuators. A mate of mine had no end of trouble with them in one if his circuit cars, apparently it's a 'known issue'.

Buy a couple of spares at great expense to ensure you never have any problems with the ones you've got!

Any clues about what the new WTAC rules might be? While faster cars are cool the Pro class arms race has got to the point where you wouldn't even bother entering without a $1m budget and even then I don't think you'd win.

There are fixes for this. In industry we use compressed air for everything. It is frequently wet, and many things cannot tolerate it. So there are various forms of driers available that you can install. The simplest option for something like this would be a dessicant drier. Much cheaper to replace some silica gel than actuator cylinders.

thanks for heads up on actuators - will sort something as back up or solution as yes dont need that have enough trouble but no doubt some addition of something to spares boxes is required

yes have a clue about WTAC but nothing has been officially put out yet so will wait to see exact details

Pro class is, has been and will become a draw card for lap records and one off builds for show and thats about it I think - be interesting to see how open they make it

Pro am is the old Pro in reality

Open class will be split into 2 with slicks and 050's with no doubt slight variances in allowable drivers and changes in aero

Clubsprint + apparently a true street class

 

They have to and are refreshing it all and bringing things up to current standards and need to 100% adhere to rules because whether people like it or not / or say it or not - for alot of competitors it is sheep stations and has been for a while

when Im getting told I was illegal because i cut my rear bumper too high and yet others where in the grey areas of legality with everything from engines, suspension, ride heights and more serious influences it actually got quite out of control and heated this year so as much as I may be impacted by some of the changes and prob spit the dummy when I have to spend money changing things I think its a good thing for all

Could you run an air drier inline to help with trapping moisture? 

I have heard some of the stories with the rules and that but I did have a good conversation the other week about the changes and possibility of another event in the USA at a famous track.

Waiting for the rules is a pain as I am trying to sort final bits of my car and want to know where I fit in.

Id like to race in the US i think alot of those track would suit me

 

For the s15? Youd be stuck between club sprint and the new Open Am wouldnt you depending on how much interior you have left in
