2016 Liqui-Moly Bathurst 12 Hour Results

The 2016 Liqui-Moly Bathurst 12 Hour ended in spectacular fashion. Shane van Gisbergen powered the Tekno Autosports McLaren 650S team to victory. Full article will be put up soon.

We have put up the first three places for the main race and each of the support races.  The link to the full results are at the bottom of the page.

Here are the race results in brief, and some fantastic photos from Chris Walsham and Bruce Moxon.

Budget DIY Corner Weight Scales

Home-Made Corner Weight Scales

Many years ago I went to TAFE with a friend of mine who we all knew as “Dangerous Dave”. I struggled in my Statics subjects, whereas Dave was a gun at it. He quickly worked out not only how to solve the problems in class, but how to apply the methods in real world situations.

Dangerous Dave concocted a rig to measure corner weights. While not exciting in itself, (there are after all many examples of homemade load cell systems on the internet) what made Dangerous Dave’s design so interesting to me was its simple elegance and an in-your-face use of science.

Dave’s take on corner weight scales was to take four cheap bathroom scales and work out how long the lever needed to be to allow the scales to operate within their functional range.

This turned out to be very simple. On a beam 1000mm long with a point load at 800mm and supported at each end will present a ratio of 4:1. That is, 600Kg at 800mm will cause a force of 120Kg at the long end and 480Kg at the short end. What that means for us is the use of a length of wood or metal on a pivot at one end, the weight of the cars wheel at the 800mm point will be easily measured with a 0-120kg bathroom scale at the other.

Take the measurement presented on the bathroom scales and multiply it by 5. This gives the true mass on the beam.

This can be scaled up for heavier cars, but the ratio does change. A 1200mm long beam with the load at the 1000mm point will require a ratio of roughly 6:1. That is, 100Kg on the scales will reveal a 600Kg point load at the 1m mark. It’s important with spring type scales to keep the weight at around the mid point of the total range as this is where they are at their most accurate.


We are back in the game

…and calling for articles!

Neil and Jim have decided to take a break from print publication which is extremely time consuming and expensive, and keep providing great technical and feature articles right here on the website.  Subscriptions aren’t necessary except for digital back issues, at least until we go back to print (most likely next year). Current subscribers have the option of a partial refund, or any back issues they are missing from their collection.

This gives us a much needed break, and presents a great opportunity to refocus on what we do best – support grassroots motor sport and car constructors with technical resources, inspiration and exciting new developments in the industry.

Only yesterday in my Facebook feed I saw a local company offer a complete double wishbone front suspension setup as a brand new fully assembled product. Admittedly it was for the hot rod community but it does show that local manufacture is still alive and innovating in the local automotive aftermarket. Arguably the world’s best engine management systems, light weight hose fittings, brakes, steering components and wheels are made here, and the Australian aftermarket and motor sport industry is worth around five billion dollars^.

If you come across something new and innovative, let us know!

We have feature car articles in the pipeline, and some great technical articles coming up too. With some luck, we may even have some left-field motor sport information related to raising finance and making the most of tax benefits! That’s a bit random, but it should help struggling teams and grass root competitors that need to find ways of making motor sport viable.

We are going to make better use of ads on the website as we still need to pay hosting fees and other business costs, but we are also hoping to put some money back into the motor sport community through car club newsletters and event sponsorship where possible.

Race Magazine is working towards being able to reimburse our contributors for their incredible and supportive efforts! We have always relied on volunteer contributors due to the lack of funds available. Your support has been incredible and we haven’t thanked you enough!

So spread the word and keep an eye on RaceMagazine.com.au and our facebook page! 2016 will be a fun and exciting year.

The Red Streak 13s for $1300

Now, we have always made a conscience decision to not cover drag racing here at Race Magazine.  Not because we don’t have any respect for it, nor because we don’t recognise it in some way, but because it’s so widely covered.  Covered to the point that it as a sport drowns out most other forms of grass roots racing.

Having said that, I feel the need to share a story with you. It is a story of internet challenges, no money, duct tape and a general lack of any sense of self respect.  I feel I should point that last part out as the base car was yet another VN commodore.  Poor life choices etc.

There are some things that Australian event organisers and venue owners should take note of that the drag racing fraternity have enjoyed for many years. The main one being ease of accessibility compared with CAMS events.  Generally, to run at a circuit or hillclimb at the most accessible club level, you need club membership, a racing licence, a car that will survive a CAMS scrutineer nit-pick, and either a day off work or wait for the weekend.  Not so with the most accessible form of drag racing.  Any given Wednesday night you can front up to Western Sydney Motorsport Park, pay your money, go through a quick safety scrutineering and then go line up for a run.  At the end of each run you stop at the drive through window and get the result on a slip of paper.  It is simple, easy, reasonably cheap and even the most under-funded motor sport enthusiast can have a go.

And have a go we did.


Driveshaft Angle and Phasing Demonstration

Found this Driveshaft Angle and Phasing Demonstration on youtube a while ago. Here is an excellent demonstration of the problems that are associated with universal (or Cardan) joint, and the importance of choosing your angles and phasing very carefully.


Porsche 3.8L RSR build

Everyone loves a good Porsche build, and this has been an interesting one!  It is being built in Sydney at Autohaus Hamilton.  I have had the pleasure of dealing with Autohaus Hamilton in the past and have been impressed with their good nature and friendliness, not  to mention the attention to detail.


Race Magazine is for Sale

Dear Subscribers, fans and readers,

 

For co-owner of Race Magazine, Jim Stevenson and I, recent changes in personal circumstances means both of us have the need to spend more time with family, as we have been hit with the perfect storm of circumstance. As a result we have decided to step back from involvement in Race Magazine to do just that.

We will print Race Magazine to the end of this year, which will be issue 44, and will try with all our efforts to find a new owner for Race Magazine for 2016 and beyond.

That’s right; the entire operation is up for sale.

Neither I nor Jim wishes to take money for a product we cannot guarantee that we can supply in 2016, because we are uncertain of the future of Race Magazine. This means that we will not be accepting any re-subscriptions from this point. However, we can accept one-off payments for the final issue ($8.80) if your re-subscription is now due. Please order these through our website – www.racemagazine.com.au

If you are a subscriber with outstanding issues beyond issue number 44, rest assured that Jim Stevenson and I will guarantee a full refund of any outstanding amount, should a new owner not be found.

We are also loading digital copies of back issues on the website, with a nominal pricing of $20 a year.  We are loading the copies starting with Issue 35, and will put a fresh one up every month.  If you have purchased a subscription through the website, you already have access to it. Take a look!  Postal subscribers will need to create a log-in on the website, and then email us so we can enable access.

In the past twelve months, we have had new contributors join us, the website has gone from a static page to a dynamic e-store, blog and platform for ad and subscriber management.  It’s only in the past few weeks the latter has been fully sorted out.  What we aren’t very good at is asking for money, so where the magazine and website really need to have a decent number of advertisers to support the operation, we have barely touched on it.  The potential here is huge, but we have run out of time.

Both Neil and Jim do want to thank you for your support. Subscribers such as yourself have ensured Race Magazine’s survival over the past 11 years.  You have made numerous suggestions that have improved what we do, and the encouragement from many of you has been very much appreciated.

In a nutshell:

  • Race Magazine, probably the only independent car magazine left that operates at a profit, is for sale,
  • Issue 44 will be the last print issue of Race Magazine until a buyer is found,
  • The back issues will still be available for purchase from the website,
  • Digital versions of the back issues will be available by subscription on the website, and will be loaded with one issue a month until they are all on there,
  • We are also in the process of loading back issues onto Apple Newsstand,
  • The website and facebook will still be active and will have regular articles and updates as always,
  • There is still huge potential here as there is a lot of advertising capacity that is unutilised,
  • We love what we have built, and the people that we interact with so we will endeavour to see that it continues!

Should you, or someone you know, wish to take the wheel of Race Magazine, please contact us at any time. Details of Race Magazine‘s sale and any developments in this regards will be posted on Race Magazine’s website, Facebook and LinkedIn pages in a few days time.

Yours Truly,

Neil Roshier

LS1 Manifold Comparison Data Analysis

Thinking of putting a carby on an LS1? Better read on before you do!

Hot Rod magazine in the USA recently did a comparison between 20 LS1 style inlet manifolds, producing some very interesting results.

The article can be found here: http://www.hotrod.com/features/1507-20-ls1-intake-manifolds-tested/

They published the data and findings on their website, but there wasn’t a lot of deep comparison analysis.  We took it upon ourselves to cut and paste it into Excel and research their findings a bit further.

The LS series of engines has become an automotive phenomenon due to their high output to mass ratio, the cheap and common aspect due to the sheer volume that has been manufactured and sold across a simply ridiculous range of vehicles.  Everything from medium sized sedans to vans and trucks.

They are a very robust engine too; able to develop decent power on stock internals and they run a hackable, tuneable Delco ECU.  Overall they are a package that is hard to beat.  The net result is the damn things get put into pretty much any platform you can think of (including Porsche 911’s and aircraft).

58th King Edward Park Hillclimb Will Be the Last One

That’s right, 2015 will be the last King Edward Park Hillclimb.  The Mattara festival from 2016 on will not include the annual round of the NSW Hillclimb championship, run by the Newcastle MG Car Club.

The park and surrounding lands has been undergoing extensive renovation and improvements, and this combined with safety concerns (both for competitors and spectators) sees the event unable to continue.

‘‘We can’t be angry at the council,’’ Newcastle MG Car Club vice-president Dave Atkins said. ‘‘We can’t stand in the way of progress for our one weekend a year.’’
