Class of 2015: Clubsprint

articleWTAC_club10

Pro and Pro Am classes have crazy aero and huge horsepower. Open class has cutthroat workshop vs workshop competition. Despite all that, it’s the Clubsprint class that has exploded in size this year, overtaking Open as the biggest class at WTAC.

articleWTAC_club19

A large and, more importantly, growing grassroots entry-level class is great for the sport. It attracts new racers while allowing them to race on the same track and at the same event as the top heavy hitters. Just like every other motorsport, time attack needs to attract new people to its ranks and that’s what the Clubsprint class is all about.

articleWTAC_club18

Secondly, Clubsprint class provides a relatively easy and inexpensive way for young racers to get into time attack racing and WTAC. As the cars competing for the outright win are hitting six digit build budgets, it’s even more important to keep the entry level class affordable and accessible to the average enthusiast.

articleWTAC_club28

With heavy restrictions, Clubsprint cars are very close to their street-driven origins and many of them are actually driven to and from the event. Jason Naidoo’s Evo (above) is one such competitor. These restrictions keep the development costs down and shift the emphasis to engine and drivetrain setup as well as showcasing driver skill.

articleWTAC_club24

Despite the restrictions Clubsprint class has intense competition for the podium spots. It is a vibrant, exciting and unpredictable class with a different winner each year.

articleWTAC_club8

Interestingly, the class record of 1:38.86 set by Nev Scott in his Subaru WRX back in 2012 still stands. Nev Scott has since progressed to Open class and this year’s winner Daniel Meredith (above) came very close to beating it in his Honda Civic with a time of 1:39.4470.

articleWTAC_club23

David Lord driving his Tunehouse-built Subaru STi shaved almost a full second off his last year’s best, finishing half a second behind Meredith.

articleWTAC_club29

Marginally faster this year (1:40.086), Jason Naidoo pinned all his hopes on the Superlap Shootout, a gamble that unfortunately didn’t pay off when the shootout got rained out.

articleWTAC_club16

Also improving this year was John Richardson in his Nissan R33 GTS-T. John’s consistently fast lap times (best lap of 1:41.311) put him amongst favourites for the class podium next year.

articleWTAC_club31

Tunehouse returned with their Toyota 86 and Josh Muggleton behind the wheel. The car underwent a complete engine overhaul with a new turbo kit replacing the supercharger used last year. Despite suffering from mechanical woes the car managed to go half a second faster than last year (1:42.34).

Scott Stewart debuted his bright orange Evo VI with a 1:42.6160.

Records, triumphs and heartbreaks

pits

Lap records, extreme weather, triumphs and heartbreaks, this year’s WTAC had it all. It’s almost customary that each year we experience some type of weather anomaly at WTAC. We’ve had extreme cold, gale force winds, extreme heat, bush fires and this year we can add torrential downpours to the list.

kalis_rain

In fact, this year’s weather provided two extremes, from an exceptionally hot Friday (36C) to a violent, though fortunately short, torrential rain on Saturday. The event certainly tested the endurance of all teams, with only the strongest ones emerging through this emotional roller coaster in tact.

Walk1

Track temperature peaked at 55.5C on Friday which was not ideal for highly tuned, high revving engines. The effects of the heat wave were immediately evident with many cars suffering with heat-related issues. Spectators were not immune either, many seeking refuge in the shaded areas and in the grand stand. The heat was so intense it even melted some upload link components causing outages during our Friday Live Stream broadcast.

Records

There is no question Tilton went into this year’s event as favourites. Though the gap between them and the competition had narrowed down considerably, the team’s experience and the ability to pull it all together when it counted put them ahead of other teams in all our online polls.

WTAC-day2-Tilton

Garth made his intentions clear by setting the pace during the Friday morning session clocking in a 1:25.09 lap. Slower than his 2014 record but enough to secure him a spot at the top of the leader board.

tilton2

With the heat easing on Saturday and temperature dropping rapidly during the day Tilton were out to set their fastest time. Garth managed to shave off a one-hundredth of a second in the morning session but the breakthrough came in the last PRO session on Saturday afternoon.

trophy

With the MCA / Shane Van Gisbergen team getting dangerously close to them, Tilton set their car to “full attack” mode. Whatever instructions were given to Garth combined with changes made to the car between session, it all came together as Garth pulled out what can only be described as “one perfect lap”.

Tilton-winning2

The new lap time 1:23.77 is not only a new WTAC and SMSP lap record, it’s also a whopping 1.1 second faster than last year’s best! Three track lap records, three WTAC titles, three incredible wins. Tilton Interiors – you’ve done it!

MCA

In the capable hands of Shane Van Gisbergen, MCA’s Hammerhead improved its 2014 PB by half a second. Not enough to challenge Tilton, but good enough for the second outright at the event and the fastest RWD lap at WTAC.

BYP

Not many people expected a new lap record to be set in the heavily restricted Clubsprint Class but Daniel Meredith proved the class can still go faster with an amazing time of 1:39.4470. The fact that he did that time in a FWD Honda Civic is even more incredible.

Triumphs

We have suspected for a while that Open Class may be the most interesting class to watch, but we could have never guessed the final podium placings. Much like in Clubsprint, a Honda has caused a major upset by dethroning the seemingly unstoppable Powertune R34 and keeping RevZone Evo at bay by the narrowest of margins.

WTAC-Day2-JDMyard

With Adam Casmiri behind the wheel, the JDM Yard Civic was not only quick but super consistent, running a string of low 1:30s laps, culminating in a winning 1:30.7010 time.

Revzone1

Snapping at his heels was Tarzan Yamada in the RevZone Evo. How close behind? One hundredth of a second. That is a narrower margin than the hair separating Tilton and Suzuki in 2014.

steveka

Things didn’t go according to plan for Dean Lillie, Steve Ka and the Powertune team this year. Just like in any form of motorsport despite all the testing and preparation you need a little bit of luck. Unfortunately lady luck looked the other way. So why are we listing this team under our “Triumphs” headline? It’s quite simple really. Lillie set his time during the hottest session of the event, in the most demanding environment.

Steveka1

The car then suffered fatal engine failure and did not compete on Saturday when all other front runners were setting their fastest laps in much more favourable conditions. Despite that, Lillie’s Friday lap was still fast enough to secure him a place on the podium and that counts as a triumph in our books.

top5-pmq

Mick Sigsworth’s campaign was not all smooth sailing either. Mick struggled on Friday clocking in at 1:29, 1:30 and 1:27. Not slow by any means but well off his 2014 best.

alexander1

Chris Alexander on the other hand was well down on his 2014 times, shaving 4 seconds off his last year’s best. Chris shot to the top of the leader board with a 1:28.279. He wasn’t able to better this time but clocked in a series of low 1:29s.

WTAC-Day2-PMQ

Feeling the pressure, Mick responded in the way everyone expected him to, by going out and logging in a 1:27.74 which put him back in the lead. He stayed out and had one final shot stopping the clocks at 1:25.75. His final time was marginally slower than his 2014 best of 1:25.27 but enough to secure the top spot in Pro Am.

article_3rotor2

This was the very first WTAC for our guests from New Zealand – 3 Rotor Racing and their Mazda RX7FD. While they missed on the podium their performance and consistency is admirable. Starting with 1:34.59 they progressively dropped their times to log in a 1:32.81 in their final session.

3rotor2

It’s also worth mentioning they did this while also managing to fix Rod Millen’s Celica after it suffered a serious diff damage on Friday. Legends!

Pro-3

The RP968 Porsche made it’s WTAC debut in a spectacular fashion. Not unlike many of the seasoned time attack vetrans, the RP968 guys suffered from technical difficulties early on but managed to overcome them and ended their very first WTAC in a 5th outright position with a very quick 1:26.80.

lyfe2

This “Triumphs” section would not be complete without mentioning LYFE Motorsport. The guys from Salt Lake City in Utah did it the hard way. Worked tirelessly to get the car ready for testing. Suffered numerous teething issues during practice, fixed them all only to suffer a fatal engine failure on Friday. Sourced a replacement engine (thumbs up to Brian Bugh for donating an R35 GTR motor) and worked overnight to have the car ready for the first morning session.

lyfe2

They started with 1:34.31 and got the lap times progressively down to finally arrive at 1:32.4050. While this lap time may not look comparable with Tilton’s time it’s worth noting that is the fastest Pro Class R35 time ever recorded at WTAC, and it was done with a stock motor! In our books that’s a win.

Heartbreaks

When we saw Under Suzuki pull over on Saturday morning with smoke coming out from his engine, we were, as most of the spectators, on the verge of tearing up.

suzuki

Like LYFE, Suzuki had engine troubles on Friday but after setting 1:25.8476 he was well within the ball park (remember Tilton’s best at that time was 1:25.09). Suzuki-san worked through the night to replace the engine and was out on his warm up lap on Saturday when disaster struck.

WTAC-Day2-Suzuki

Another engine failure prematurely ended Suzuki’s dream of winning WTAC though the time he set on Friday secured him a place on the podium.

suzuki33

As the event drew to a close we caught up with Andrew Brilliant and asked him if the Scorch S15 (had it not been out of action) was capable of matching Tilton’s new record. “Definitely,” he replied, “it was built to do those lap times. And lower!”

Forrest1

Another victim of WTAC’s demanding conditions was Andy Forrest whose car suffered gearbox failure on Friday and despite everyone’s best efforts we were not able to get the car back on track for Saturday. Andy’s WRX spent the event on display at the Whiteline tent.

sva1

Last but not least is the SVA Imports. With a lap time of 1:29.9280 run with a very conservative setup, Gareth Lloyd was in with a shot at the podium at the very least. The car went out on Saturday with the NOS and the boost turned up ready to shave some seconds off and have a good crack at getting into the top three.

The very next thing everyone saw was the immaculate white Evo VI parked on the side of the track with flames bellowing from the engine bay. Gareth Lloyd managed to put the fire out but by then the damage was done and SVA’s chances of standing at the WTAC podium crushed.

article_suzuki3

WTAC is a tough event that places extraordinary demands on the drivers, the crew and their machines. While time attack racing is not classified as an “endurance” race, endurance is exactly what the teams need to survive and succeed.

The passion, dedication, perseverance and the sheer staying power displayed by the WTAC teams this year is nothing short of amazing. And for that, we salute you!

Staying a-LYFE

article_WTAC_Lyfe01

Though WTAC is still a few days away, another kind of race is already underway in workshops around the country – a race against time to have their cars prepared and ready before the flag drops on Friday morning at Sydney Motorsport Park.

We took this opportunity to sneak up on the LYFE Motorsport team and get you some behind-the-scenes photos of their Pro Class R35 GTR.

article_WTAC_Lyfe02

Andrew Brilliant’s aero package is what sets this car apart from any other time attack R35 GTR.

article_WTAC_Lyfe03

From this angle it’s obvious just how much wider than the factory car the body work is. Add to it the front splitter and you’re starting to understand this car was built for downforce and aerodynamic efficiency.

article_WTAC_Lyfe14

All those little canards and winglets form a part of the overall package and, when working in unison, give the car with just the right amount of downforce at just the right time.

“The biggest difference between the cars we’ve built so far and this one is the aero package. It plays such a crucial part in time attack racing at this level, we made every effort to get it right from the start. That’s why we got Andrew Brilliant to design a package specifically for our car.”

“We are fortunate enough to have the support of the best names in the business. Guys from RallySportDirect, AMS, Dodson Motorsport and Wisefab have been instrumental in this build.”

article_WTAC_Lyfe12

The heart of this beast is a fully built, dry sumped 4L stroker VR38. Running on ethanol, the motor uses a custom built AMS Alpha turbo system and pumps out in excess of 1200hp.

article_WTAC_Lyfe17

Fuel system is by Radium Engineering and Fuel Safe and uses AMS Fuel rails, ID 2000 injectors and three Walbro 450 fuel pumps. All fluids are by Motul.

article_WTAC_Lyfe13

All that power is transferred to the wheels via a factory transmission with a Dodson Motorsport gear set. Front diff is a NISMO unit while the rear is by OS Giken.

article_WTAC_Lyfe08

A factory transmission, you ask? That’s right, the guys even kept the original factory gear shifter in the cabin!

article_WTAC_Lyfe07

Gear changing is done via a Works Bell steering wheel mounted paddle shifter. Power steering is an electric/hydraulic hybrid. A full MoTeC system looks after all engine management and data logging duties.

article_WTAC_Lyfe06

An auxiliary control panel with some of the original GTR factory switchgear is a nice touch.

article_WTAC_Lyfe11

Who said race cars have no room for mod cons? Check out the “cool shirt” and “cool seat” buttons on the console.

article_WTAC_Lyfe09

Weighing in at approx 1500kg, LYFE Motorsport R35 GTR is not a light car by WTAC standards. While the engine has more than adequate power to propel all that weight around the track, the car also needs some serious braking power to slow it down.

article_WTAC_Lyfe05

The “slowing down” side of things appears to be well covered. Steel brakes pictured will be replaced with a full carbon set come Friday. The wheels are Volk TE37-SL 18×11 and will soon be wrapped in Yokohama A050s.

article_WTAC_Lyfe04

The suspension system is a work of art with Wisefab providing most of the components and even flying a technician all the way out from Estonia to help with the setup. Whiteline provided their signature sway bars.

article_WTAC_Lyfe10

The man charged with steering this beast at WTAC is Cole Powelson. While he may look calm and relaxed in his Racetech seat above, Cole wasted no time familiarising himself with Sydney Motorsport Park.

“I went out yesterday and spent most of the day driving around the WTAC Circuit in a Formula Ford car. It’s a technical track and I really enjoyed it. It has a bit of everything, high speed corners, low speed corners, elevation and a long straight.”

“The closest track back home would be our local Miller Motorsport Park in Utah. It has a similar mix of corners but no elevation.”

article_WTAC_Lyfe16

“Give me plenty of power, loads of downforce and I’ll take care of the rest!” Cole Powelson exchanges notes with LYFE Motorsport co-owner, Doug Nephew.

When asked if he was worried about local drivers having a “home advantage” Cole replied:

“A full day of driving is enough for me to be comfortable with a track. To be honest if you can’t familiarise yourself with a new track in one day you’re not a pro driver. Our focus now is to get the car doing what it needs to be doing. Everything else will fall into place.”

article_WTAC_Lyfe15

“See, even Angry Birds fly backwards in Australia” Ian Baker explains the practical application of Coriolis effect to the LYFE crew.

“Thanks to the guys at HyperTune and our team, who have worked tirelessly on the project, we are now well on track to have the car 100% ready for our first full practice day next week.”

LYFE Motorsport are one of the most committed and dedicated bunch of guys we have ever had a pleasure to meet and we wish them all the best next week.

Under Suzuki’s final pre-event test at Fuji

0P8A7723

Scorch Racing at the 2014 WTAC: the only Japanese team capable of taking on Tilton head on.

There is no question that Under Suzuki has only one thing on his mind and that is to become the fastest time attack driver in the world.

That has been the case ever since he first toured here way back in 2011 and every single year since. Finishing within 4 hundredths of a second behind the champion Tilton Evo in 2014 and taking the runner-up trophy proved that Suzuki-san has the car and the driving skill to match it with the best of the best.

suzuki1

In 2015 subtlety is out and “function over form” is in. Every extra canard, every extra kilowatt could be the difference between winning and coming second.

Knowing that in time attack racing not evolving means going backwards, this year he will unveil by far the craziest incarnation of a S15 Silvia the world has seen to date. The team were busy getting a final test session in at Fuji Speedway on the weekend and certainly turned some heads with the radical new aero package.

wtac_suzuki1

Most noticeable was the massive front splitter built to the absolute maximum the rules allow in every regard, high mounted front canards and some crazy side canards.

We’ve done well last year with an aero package that was

far from finished – this year we are very close.

The team was reluctant to give away too much information but what we did find out is that they are packing a fresh NAPREC built 2.2 litre motor, full of all the top-shelf bits and now controlled by a full MoTeC system, replacing the old F-Con that has been on the car since the beginning.

The new engine management will no doubt allow much greater control and data acquisition that is so important at this level of competition.

suzuki3

Andrew Brilliant, the brains behind Suzuki-san’s aero package was a little more forthcoming with info:

“We actually came up with most of these design two years ago but it just takes so long to get everything done. Remember it is just him and a couple of his buddies in a shed making all this stuff and a lot of it is quite complex.”

“On top of this, he has to work a hell of a lot of hours at his real job to pay for all the expensive parts so it really is a continuous uphill battle. What I can tell you though is that this year he should be on the money. While he may have done well last year I can assure you that aero package was a long way from finished. This year it is very close.”

“We have also tried to keep the front a lot more subtle in the past but looking at the competition in 2015 we would be simply giving away far too much. Subtlety could cost us precious time and Suzuki-san is going down there to win so his attitude now is – we need to do whatever it takes to win.”

suzuki999

Subtlety will cost us valuable fractions of a second,

we need to do whatever it takes to win!

As a very exhausted team packed up at Fuji Speedway and headed home Suzuki quietly announced:

“I am going home to go straight bed. I have not slept at all the past couple of days in order to get everything finished. And the week before was not much better. Once it is on the boat I think I will sleep for an entire weekend!”

suzuki5

If you want to wish Under Suzuki good luck at this year’s WTAC, do so on his Facebook Page.
And of course the best way to cheer him on is to be at Sydney Motorsport Park in October.

Understanding WTAC: Tyres

WTAC_Tyre_howitworks

World Time Attack Challenge is running on a Yokohama Advan control tyre across all classes. This provides a fair and even playing field and prevents any team from getting a “special treatment” as all tyres are ordered in bulk and available to all team.

All teams have to complete a tyre pre-order form ahead of the event and the tyres are supplied directly by Yokohama. There are no “special” tyres or “special” orders. Teams can choose any combination of soft or medium compound tyres within their class quantity and size restrictions.

 

WTAC_Tyre_enforcement
All tyres are marked by WTAC staff during scrutineering. There are random checks throughout the event and the top five cars in each class is inspected closely by WTAC eligibility scrutineers prior to any trophies being issued. Any car found to be using any tyre other than its specified control tyre is disqualified.
