Advan/ Hi Octane GTR powers up for 2012

With the new improved aero package for 2011 on the Advan/ Hi Octane R34 the quest for more horsepower was always going to be on the cards for 2012.

“The car is a totally different animal now with proper aero” said Mark Berry “What we were struggling to keep on the track before, now feels quite conservative as the car sucks itself to the track and we could certainly make use of more power especially if it is in all the right places”

The R34 was back at CNJ Motorsport in Brisbane this week and was cranking out some very serious dyno numbers thanks to some fine tuning on E85 and a switch to a totally different turbocharger

“Spiro at Dragons Lair Motorsport  in Queensland has jumped on board with support of the latest Precision Turbocharger direct from the USA” said Mark “and the first signs have been very positive, in fact we have made a gain of 70kw from our old combination. This is a fantastic result considering this is the first turbo size and combination that we have tried from the Precision range. The turbo produces very surprising results straight out of the box and we cannot wait to get it on the track. I would like to thank Spiro for his ongoing help to make even more improvements before we hit Eastern Creek in August”

Whilst we were made to promise we would not show the dyno graph we can tell you that though it produces a drag racing type horsepower figure at peak revs this 3 litre engine also appears to make buckets of power everywhere and certainly the Advan/Hi Octane team are one of the many Australians that are stepping up their game yet again before the foreigners arrive and by all accounts spending countless hours chasing every small detail to take on what can only be described as the most competitive pro time attack field yet.

Thanks to Hi Octane Racing and Yokohama ADVAN.

Advan/Hi Octane Racing R34 GTR confirmed

Hi Octane Racing has confirmed entry into World Time Attack 2012 in the black Advan backed R34 GTR. This is the same car that debuted on the podium at the final Superlap event at Oran Park 2009 and has been in a constant state of development ever since with the latest reincarnation certainly the wildest with an insane aero kit designed by ex Mc-Laren Formula One engineer Barry Lock.

“To be honest it is a totally different car with the new aero” said Mark Berry “And as we only finished the car in the week leading up to WTAC 2011 we had zero test time yet I was still able to take over two seconds of my previous years lap time, all of which I contribute to the aero”  This will give a fair indication of the potential of this car as the team were also plagued with serious mechanical gremlins last year, including the lifting of the cylinder head which forced them to run a much lower boost pressure than optimum and therefore much less power.

“We were certainly running a very conservative tune last year but after putting that much work in, our main objective was simply to be there and finish” said Mark Berry “This year will be another whole story. We will have months to fine tune the setup and also learning to drive with aero is another animal altogether. We are confident there is a few seconds still in this car, which all going well should move us up closer to the real pointy end, but having said that we also expect many other teams will be doing a lot of work in the off season too. The competition is bound to be more serious than ever in 2012”

The car is powered by a dry sump RB30 built by Hi Octane Racing with a RB26 head and stuffed full of all the good gear with CP Pistons, Pauter connecting rods and a RB26 head full of Tomei gear. Whilst they were coy about actual power figures we were told that this E85 powered monster makes somewhere around 500kw at all four wheels on maximum boost depending on turbo choice. This is another area that will be the subject of much testing but needless to say the car will now run a large single turbo of some description. The car will also run on Advan wheels with soft 295 AO50 tyres all round.

This team has been a driving force behind the time attack scene in Australia since competing in the previous R32 GTR at Tsukuba in 2007 and there is no question that they would like to add some more silverware to the cabinet. Will this be the first Australian car to run under 1.30 on R tyres? We will have to wait until August to find that out.

WTAC 2011 through your eyes…

Through our Facebook Fan Page we have received a number of photos showing us your experience at the 2011 WTAC. We want to share the best of those with you here…

This is how close to the action you could get as a spectator. Try doing that at any other motorsport event!

International drivers weren’t the only ones in high demand for posing with…

Now Tarzan I want you to drive fast but don’t break the car….

Dangers of posing with a tall model: your attention can get easily misdirected…

Looks like one of the crew is desperately trying to stop the Tilton Evo from getting onto the track…

Now then what’s going on here… Ah, yes now we see it!

If you can’t get a ride in a real car, there’s always the simulator!

Tarzan and me. Take 6476…. and counting!

“It’s about THIS big… honest!”

We can’t help but think that the wrong model ended up on the bonnet of the car…

Tactics and Mind Games in the Pits

Go back to 12 o’clock midday on Day 2 of the 2011 World Time Attack Challenge. Sierra Sierra have just pulled a 1:29.0240 lap, seemingly out of the bag, while Cyber Evo only managed a 1:29.7510.

The Cyber Evo team protest, claiming that Sierra Sierra must be running nitrous, that no car that heavy could be running speeds as fast as they were down the straight. The scrutineering team are called and the Sierra Sierra team lose a mechanic as they have to prove there was no nitrous in their car.

This all happened as the Sierra Sierra team were frantically changing a head gasket in order to get the car out for the next session. Were the Cyber team afraid they could not better the time, or merely sandbagging and masking the true potential of their car.

Of course no nitrous is found on SSE car and things go back to normal, but the SSE team is disrupted and now has to work extra hard to regroup and refocus on the task ahead.

Let’s rewind a little further back to the Thursday practice sessions during which all teams run their own timing systems, not the official timing beacons used during the two days of the WTAC. When quizzed about their lap times, most of the top teams will answer with a vague nod, a smile or a non-committal “pretty good/happy with the times/roughly what we were expecting” type of reply. Despite knowing, and we suspect in quite a lot of detail, exactly how quick their car can go, most hold their cards close to their chests, so the true potential of the car wouldn’t be easy to guess.

Another common practice is doing ‘partial lap times’. Rather than doing a full hot lap, the drivers would do a moderate lap and only push through one section of the track. Add up all the split times, and you get a good indication of the lap time the car can run, without giving the game away to the competition.

The mental game continues on the race day. With the two best sessions being the morning and late afternoon sessions in terms of track temperature, getting a good hot lap off without staying out on the track too long is crucial to making sure the car doesn’t become overstressed and have a mechanical failure.

Once on the track, the idea is to stay as far away from your direct competitor as possible as you prepare to do your hot lap. When two cars with similar capabilities are on a hot lap you really want to avoid overtaking or indeed being overtaken by another car. A competitor with similar speed might not want to concede his spot. Ideally you want a clear track ahead of you where all you need to worry about is getting around the track as fast as possible.

So despite the fact that Time Attack is not a “head to head” race, there seems to be a fair bit of tactic involved as teams try to outsmart each other in the pits and jostle for the best position for their hot lap on the track. At the top end of Time Attack, where 1/10th of a second changes you from a champion to a  runner-up, where the cars run at their limit and every single element needs to be perfect, strategy becomes a crucial part of getting that perfect lap.
