2011 Series Newsletter Number 4 - May 23rd 2011

Register grows - There has been a huge response to the 2011 Motul HondaCup, with around 50 drivers registering to take part in the third edition of the series. What is particularly interetsing about those registering is the number of serious newcomers.

The series has been talked about extensively on the various forums and it looks like there will be a good turnout for round one on the Taupo short circuit. It's still possible to be part of the Winter's top series but you'll need to act fast and get your application and entry in pronto. You can do this at the web site at www.hondacup.co.nz

Class of 2011 Photograph - As you will all be aware, we are trying to create a really top notch gallery of the cars competing in this Winter's Motul HondaCup. One photograph we would like for the web site and the galleries is a 'Class of 2011' shot that will include all of the drivers who race in Round 1. We thought the best time to do this would be immediately after the driver briefing this Sunday before the action starts and it would be GREAT to have everyone on the photograph wearing their racing overallas and with crash helmet in hand. We will make this shot availabel to everyopne in the series. Alan will make an announcement about it at the briefing, so there are no excuses!

Surtees Trailers - HondaCup only offer! - Surtees Trailers have been an enthusiastic backer of racer Gary Wilson and before him Phil Nobblett and will once again be behind Gary as he races in this winter's events. As a special offer open ONLY to Motul HondaCup registered racers, the company has agreed to offer a fantastic 10% discount for any regsieterd member off the normal unbraked standard single axle racecar trailer with 13" wheels with removal ramps (normally priced at $4500 incl).

These are also some of the best guys around to discuss trailer requirements with - as they have vast experience in creating both bespoke and stock trailers for the transportation of race cars.

Custom plates - Fancy a plate just for your car when it races with your name or a sponsor on it? Racer Tristan Neate is offering these for just $10 and they'll be ready for Round 2. Tristan can tell you what limiting factors there are in terms of numbers of characters but the sky's the limit! Contact him at tristanDOTneateAT gmailDOTcom or you can call him on 027 2002823.

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

Ladies and gentlemen - start your engines

Just a few days to go now before we blast off for the 2011 Motul Hondacup series and it is shaping up to be a classic with plenty of registered racers and a solid entry for this weekend.

There is a spread of engine options across the field and there are sure to be a number of battles at the front - especially with some quick B series powered cars keen to topple the mighty K powered machines. The tight and twisty nature of the short track at Taupo will be the best opportunity of the entire Winter series for the smaller engined cars to make their mark.

Confirmed front runners are Trevor Strong and Martin Dunn with their K20 powered Ek9 and DC5 chassis respectively, while Brent Thompson in his K powered EG and Shaun van Beers in his DC5 should shine too. Watch out too for Rob Sutherland in the blindingly fast K-powered DC2 if he races and series regular Colin Abah in his lovely K-powered EK. Mark Walters is also down to run and is always quick at Taupo.

Series director Alan Stewart will be quick in his much modified B powered DC2 and Gary Wilson and Richard Gee (pictured) should also be quick amongst the 1.6 runners. Tim Blackwell-Chin will be out to show that recent work on his chassis and engine has been worthwhile too. There are plenty of new runners to interest spectators too, with many making their racing debuts and maing the big step up.

"Fun is the name of the game and it looks like an excellent field lining up for the first weekend," said Stewart. "In the current climate, it's great to see so many new faces amongst the regulars. We'll be trying to get aorund everyone on Saturday and on Sunday morning to say hello and get the cars branded up correctly for Sunday so it will be great to put some names to faces."

Looking after her - Part 2

In regard to lubrication and cooling, because an engine uses combustion to make power it generates a lot of heat so in order for the engine to stay cool it has a water cooling system to take heat from inside the head and block and transfer it to the air through the radiator.

This is only part of the process because while your radiator is busy cooling water your oil is busy being pumped through the engine directly over the moving parts such as big end shells, pistons, cam journals and lobes etc.These are ‘hot points’ in the engine, in many cases the oil then takes heat away to an oil cooler (radiator) so the heat can be transferred into the air, how well your oil carries the heat away from the hot points will depend on how effective it is at cooling the inside of your engine, this will also have an effect on the life span of the oil in the motor.

The additives package in any given product is there to do certain jobs, it has detergent to keep your engine clean inside, it has dispersant to keep all the heavy particles like iron, alloy and carbon suspended in the oil so it can be filtered out and any not captured by the filter drains out when you give the engine a service, and it has anti-wear additives to protect moving parts from damage when there is too much pressure for the oil film as I mentioned before. The important thing to remember is that oil companies don’t manufacture these additives they have to buy them in so the only way to reduce the cost of these additives is to add less of them or to use lower quality additives, hence the saying “it is impossible to make good oil cheap”.

Aside from all the heat and pressure that your engine oil is dealing with there are other factors to consider, we can break these down; Friction, Wear, Shear Stability, Oxidation Stability, HTHS and fuel dilution.

In this newsletter let’s look at shear stability and fuel dilution. Shear stability is a measure of how oil is ‘chopped up’ by piston rings etc, and it has a direct adverse effect on your oils viscosity, if the oil is not very shear stable it will lose viscosity and your engine will lose oil pressure and as you already know you need the oil to be pumped around the engine to keep the hot points cool and lubricated. Oils that have good shear stability will maintain better oil pressure than oils with bad shear stability. Of course you could just start with really thick oil like a 25w50 grade to combat shear loss and to maintain oil pressure however that will be costing you power at the end of the crank through drag and too much oil film on the moving parts so you could use a 0w20 to reach better power output but without shear stability our 0w20 would run out of oil pressure after maybe 10 minutes on the rac e track and also may not offer enough film strength to protect the moving parts from coming together and wearing prematurely.

Fuel dilution is the only factor that we have control over all the others are up to the oil chemist that developed the oil you choose. We can control the fuel dilution because you all either tune your own engine or have it tuned by someone, a good tune won’t be putting more fuel into the engine than it can burn up efficiently, a bad tune will and some of that extra fuel will end up in the sump mixed with your oil. How well tuned an engine is will determine whether your oil can focus on all its other jobs (cooling, lubricating etc) or if it will also have to do these jobs while being thinned out by half burned fuel. Oil that is thinned out from fuel dilution is never as good as oil that is free of such contaminants.

Just think of it like this; you are trying to use the lowest viscosity you can (5w40) to achieve the best power output while protecting the engine, but if you then thin the oil down by around 5% with half burned fuel over the duration of a race or even half a race you 5w40 will be heading down the road of a 5w30 or even a lighter grade if there is a worse over fuelling problem, as we know the lighter grade leaves us open to oil pressure and surge problems. In short, keep monitoring your oil level and condition, if the oil volume is increasing or the oil is starting to smell a bit like petrol rather than oil the chances are is it is getting a lot of fuel in it.

Thanks to series sponsor Motul for these words of engineering wisdom.

Team trophy wins Speedfactor backing

Speedfactor - one of the Honda racing scene's top tuners - is to sposnor the 2011 Team Trophy in its inaugural year.

The Tauranga-based company is creating a unique trophy whjich will be presented to the winners of the new team trophy after the final round of the 2011 series. Speedfactor prepared the 2010 Motul hondaCup and 2010/2011 SS2000 series winning B-powered DC2 pedalled so effectively by Justin Herbert (pictured).

"It's great to have Speedfactor on board and proof that the series is gaining credibility amongst the tuners and after market specialists," said Alan Stewart. "There are only a few really specialist tuning/preparation and fabrication specialists in the North Island and we'd like to see all of them involved."

Speedfactor joins other series sponsors with its own forum area on Motul HondaCup and will be making special offers to series racers as well as providing technical feedback and answers.

"It's great to see good numbers of Honda racers and with more being built, the series will offer something spectacular for enthusiasts," commented Speedfactor's Evan Pitman. "We have been supporting amateur, club and national racers for 10 years and we are always keen to help with continued growth of the sport."
