With a disappointing end to the season with brake issues and having run out of budget, it was a good decision to pull the plug for this year and focus on getting the car ready for next season. Now with the intent of running a full season from start to finish on the cards this will be my first proper go at the championship and with experience gained over the past season i now know what I need to achieve with the car to get it to run up front without breaking out of the GT2 class limit. Again doing this on a budget is key but at the same time getting everything together during the off season, like spare brake pads discs tyres all consumables to make sure I’m not caught out part way through the 2012-13 season, making sure the car is as reliable as possible. So! Very little will be done to the engine other than a basic freshen up and check over, i am going to run E85 fuel with only a 80-100hp ATW maximum increase, with a huge leap forward in torque above what BP98 can offer due to engine timing freedom.
Most importantly will be the aerodynamic modifications, it was always the intent to build a traction car, not just a raw hp car. With a projected wheel hp figure of 500-503 and a small weight reduction of 20-30 kg, taking the car to just under 1100 kg wet, less driver and with a better weight distribution and proper aerodynamic changes should make the car considerably faster.
The biggest change will be the front wheels wells. This is one of the most important cheap mods you can do to a race car to decrease drag and lift in one hit. by removing the flat firewall component of the wheel well and rounding off to the door area relieves the pressure build up in this area. I will be flowing the body work from the wheel well right round to the rear guard passing under the top half of the original door. This will be fabricated in .7mm high tensile aluminium alloy with a .9mm bronze anodized outer skin to finish, producing a smooth air flow along the side of the car at the same time feeding air ducts to the rear brakes, shocks and diff.
The front bumper and splitter will be changed to accommodate front brake ducting and a reduced splitter to save weight and drag now the wheel wells are altered there is no need for a large high drag splitter to fight the lift that was present up till now. The front of any GT car is always the hardest to get down force and aerodynamics to work well with the front always first into the airflow and a lot of turbulence exists under the engine bay with little room to play with big wings and diffusers are not easily achievable. So with the front of a race car you need to focus on clean airflow with minimal drag and good control of the air over the rest of the car
Finally I have a secret weapon I am going to adopt at the rear. This will remain under wraps till the season starts and if it works as planed this will make the singe most biggest difference to the cars performance.
For now though all will be quite.
