2011 Series Newsletter Number - May 16th 2011

Dr Frankensteins monsters - There should be some absolutely fascinating vehicles at Round 1 in a couple of weeks. Confirmed entries include series sponsor Tim Pollard in his superb ex-factory series DC5 racer and Richard Gee in his SS2000 1.6 Honda class championship winning car. There are plenty of K20A and B series powered vehicles down to run, and collectively they make up just about every combination of EB, EG, EK, DC2 and DC5 chassis and engine you could imagine! And there are innovations and ideas on every car that are worth a good close look.

Sponsor Area of the forum - You'll all know how tricky it is to get any sposnor these days for anything, let alone a bunch of them itching to sposnor something in motor racing!

Motul HondaCup counts itself as extremely fortunate that it not only has a great title sponsor (and a sposnor who comes and races too!) but also a group of other enthusiastic supporters keen to see the series succeed and develop. The sponsor area of the forum has been created for them - primarily so they can talk to you directly and answer technical questions and provide products and services where appropriate to meet your needs. You can ask them questions in the forum area too. As the community grows it should definitely be a good place to go for advice, products and deals!

Racers to head stateside - Five of New Zealand's Honda racing regulars are progressing plans to race in the USA in December in a very exciting car in the Thunderhill 25 hour race, a massive Californian equivalent of the Nurburgring 24 hours that features drivers from rookie level right up to Indycar and Daytona 24 Hour champions. It's all come together with the help of the USA's equivalent of the Motul HondaCup and who knows, one day we might have US racers down here to sample Hampton Downs in a race prepped EK9!

Dates - a reminder...We'll include these dates in each of the forthcoming newsletters - so there's no excuse for missing a round!

There are just two weeks to go before Motul HondaCup 2011 blasts off and entries are literally coming in by the day but DO make sure you have registered for the series FIRST as we don't want to have to spend ages at Taupo doing paperwork when we can be talking cars and how to make them and you go faster!

You can download the documentation for registration on the Motul HondaCup web site (www.hondacup.co.nz) - these are Word documents and are the new format Word files. If you struggle, email either Alan or Richard using the contact details on the left and we'll send the paperwork through to you.

Details of accommodation are also in this newsletter (see below). We will try and advise in advnace of every round what the best options are for accommodation on the basis of a cost vs quality balance!

Looking after her - Part 1

If you are planning to go racing it is almost a certainty that at some point you have asked yourself “What oil should I put in my engine, gearbox and differentials this season?” For some people it will be simple - the same as last season, but for others it may be a harder choice, perhaps this year you have a new car or just a new engine, perhaps after last season you had to spend a lot of money on your engine due to unexpected wear on the internals? Either way this series of articles is designed to help you choose a product that gives you the results you need.

Careful choice of oil for your engine can mean the difference between finishing your race or getting towed back to the pit lane. Similarly it could mean the difference between an engine that lasts many seasons of racing or an engine that needs a rebuild after just one.

Over the next few newsletters we will cover the different aspects of lubricants for Engine, Gearbox, and Differential starting from the simple process of choosing what viscosity to use through to the more technical part of what it is going to do in your engine and how that will affect your engine - and perhaps your wallet.

To start with we will look at oil viscosity. We put oil in an engine to serve multiple purposes but mostly to lubricate and cool the moving parts inside.

The lubrication process has three objectives - reduce friction between the parts moving over one another, create a barrier between those parts to avoid damage or seizure, and in cases where there is too much pressure between those moving parts for the oil film to continue protecting them use additives to stop the parts welding themselves together. This is commonly known as seizure, but even minor contact between moving metal parts results in engine wear, the result in the short term is loss of performance. Long term, you are looking at an engine rebuild.

What oil viscosity we choose has varying effects on an engine. Let's take the good old Honda B18c motor. Honda designed the engine to use a viscosity in the range of 5w40 or 10w40; however they also designed the engine to drive around on the road as a sport/passenger vehicle. When we take these motors racing the requirements of the engine oil change somewhat, we want to get as much power as possible but we don’t want to compromise engine protection.

To make things more interesting for Honda racers the B18c and just about every other racing B series is a V-Tec engine and so requires consistent oil pressure to maintain performance. In fact all race engines prefer to have consistent oil pressure to avoid engine damage but the driver will notice straight away when this happens from the resultant loss of power.

So what oil viscosity should we choose? From our experience at Motul New Zealand the most common viscosity choice for the B18 and indeed the B series as a whole is 5w30 or 5w40, these are good viscosities for both power and engine protection.Using a 5w30 over a 5w40 will no doubt result in slightly improved performance but unless your engine has a well designed sump to avoid oil surge on long sweeping bends you will most likely experience the oil pressure issues I spoke about before.

The other thing to keep in mind is that lighter viscosities of oil need to be of higher quality to maintain engine protection so when choosing what to run this season make sure you enquire about the quality and construction of the product along with viscosity, and we will cover these aspects in the following newsletters.

Accommodation news

Accommodation at Taupo is plentiful and not too expensive and Tim Blackwell-Chin has sorted out a good group buy at the Chelmswood Motel (see picture) and has got a great rate organised for competitors. You can book your accommodation by emailing Tim as soon as possible on mhr@marvelnz.co.nz - he can let you know exact costs but basically the more people who book the cheaper it becomes!

Other options range from the very cheap to the hugely expensive, but one popular alternative is the Taupo Motel (0800 333442). It's of a nice standard and the owners know the racers well and may actually be doing your documentation when you sign in!

Either should be a great choice and easy on the budget.
