Our plans to get a single make championship/series off the ground for the SC09 V8’s has been hindered due to lack of commitment. We still very much plan to run with the idea, however it will certainly require more time and effort and we hope that throughout the 2016 season more people commit and get stuck in. The general feedback from everyone is that it is something people want to be a part of, there really is nothing like this in the UK and let's be honest nothing beats the sound of a roaring V8, let alone a whole grid of them! We will still be racing this season, but we will be joining in with other grids until everything falls into place. We have recently been undergoing a project with one of the SC09 race cars and would like to take this opportunity to share our plans with you. A more competitive package is required to enable a front running car in a GT4 class in events such as Britcar, GT Cup, 750MC and MSVR. Perhaps the most easily identifiable issue with the standard SC09 is the vehicle mass. Currently at 1550kg these are on the heavy side for a race car. As much as we would like to think they are Aussie V8 super cars they are quite a long way off. They are in essence a GT4 version of a Vauxhall VXR8/Chevy Lumina/Holden Commodore. There are two avenues to investigate to deal with its current power to weight ratio; add more power to the engine, or, remove as much weight as possible making a more nimble package. Removing weight was the route dictated to be initially investigated. A combination of the both may prove to be the optimal route in terms of performance, perhaps not for cost though. Starting at the current weight, a loss of 300-350Kgs is required to be removed in order to put the car in the power to weight ratio of where we are aiming to be. Getting that much additional weight out of an already stripped vehicle is difficult, time consuming and costly. However if the more than capable power-train ends up in a lighter car the rewards will soon become apparent; it will accelerate faster, brake faster and corner faster. As a starting point we stripped one of the cars down to a bare shell and recorded the weight of each component to assess the weight saving possibilities. Not surprisingly the chassis is the largest mass at around 700Kg. This is obviously an area of concern as things like the engine and drive train are not going to change much. For example the front end assembly as a group weight is nearly 520Kg, these items won’t change therefore this is a known mass of the final vehicle. Moving onto the shell; there is already a substantial roll cage which extends to the front suspension struts; by altering this structure to be more like a space framed chassis vehicle we can remove most of the floor pan, transmission tunnel and bulkhead. These can then have bracing areas welded back in and lightweight flooring bonded and riveted. All the current bodywork is heavy, even items such as the bonnet and front bumper that are already moulded from GRP are heavy; this is mainly due to poor manufacture from the original supplier. There is a substantial amount of resin incorporated into these panels which is totally unnecessary weight. The doors and a lot of the other body work have had a lot of body filler put on them in the past along with many layers of paint. With this in mind we will be planning to replace these panels with new vac moulded GRP pieces and only minimal paint applied. Just the doors come in at around 100kg total! The suspension components are modified standard units for the most part. Upper and lower control arms on the front and rear are bulky cast metal with in some cases large machined housings made to be inserted into the standard bush holes to accept plain spherical bearings. A more long term plan is to redesign these components and make them from tubular equivalent with the correct housing sizing for the bearings required from the start. Machined uprights would also be another consideration as all of these OEM style parts are very heavy. The sub-frames are modified standard items. They have been seam welded for the most part and have solid bushes machined to fit in the standard bush holes. More weight can be saved by once again making these from a tubular equivalent, along with adding more adjustment for suspension geometry. As you can see we have a lot to think about and design, but once we have the shell sorted and we can start testing we can then think about the further development of these other items.
