September brought about another of our popular STM Squad track days at Manfeild in Fielding. These days are becoming more and more popular, with this one filling up weeks before the event. If you aren’t familiar with our track days, they are the easiest and lowest stress way for you to get your car out on the race track.
All you need is a road worthy car, a pair of cotton overalls a drivers licence and a suitable helmet. These track days are classed as ‘non competitive’ which makes them ideal for those new to the race track. Passing is not allowed in the braking zones or through the corners and this adds up to a super safe environment where you don’t need to worry about getting hit by others.
Along with our customers, we also had Project86 back out on the track to see if we could improve on our lap times. The only change we had made since its last outing was the D2 Big brake kit. This proved to be a valuable addition allowing us to brake around 20 metres later. Just as important was the confidence that the brakes would last lap after lap. The result was an improvement of 0.8 seconds, with a best of a 1:23.1 lap.
We rely heavily on the Motec CDL3 dash fitted to Project86 for data logging and analysis to help improve the car. One issue we found is with the added cornering g forces, we are now starting to suffer from oil surge. This is something we will be focussing on immediately to prevent potential engine damage.
We hold these track days regularly and if you want to get involved, we suggest you register early. Check out the Events section of our website for upcoming track days.
High quality, sticky rubber is one of the most important parts of any well balanced performance package. We recently headed to our STM Gymkhana test track to test the Nitto NT01 and the Nitto INVO and record their improvements over the stock tyre. Watch the full video below.
Aftermarket fuel pressure regulators (FPR’s) are one of the most popular items people buy when starting to modify their car. The truth is that aftermarket FPRs are more often than not unnecessary and the factory FPR will do the job just fine. Let’s have a look at when you should be fitting an aftermarket FPR so you don’t waste your money:
If you are fitting a mild fuel system upgrade such as a Walbro pump and/or larger injectors then the factory regulator will cope quite happily.
If you are getting near the limit of your injectors and just need a little more fuel to get by, an adjustable FPR can be used to increase the fuel pressure and hence the flow of the injectors. NOTE: This is only suitable for achieving small increases in injector flow of around 5-10%
If you are fitting an aftermarket fuel rail kit, then usually there will be no provision for the stock FPR. In this case you may have no choice but to use an aftermarket unit.
If you are installing a large fuel system with bigger lines then the factory FPR may be too restrictive resulting in uncontrollable fuel pressure. In this case a higher flowing aftermarket FPR is the solution.
When buying an adjustable FPR, stay away from the cheap-ass Chinese products. While these may save you a few bucks over a quality name-brand product, inconsistent fuel pressure can also cause expensive engine damage.
If you have read the tips above and you have decided that you do need a FPR then get in touch with us. STM can supply a wide range of adjustable FPRs to suit just about any engine combination or power level and we can advise you on the best product to suit your requirements and budget.
