Apexi Super Lightweight Racing Exhaust System Don't get me started on exhaust systems. Too late ;) Boy racers seem to think that a large bore pipe means more gas will flow meaning that the engine has an easier time and hence produces more power. Unfortunately it's not that simple and manufacturers spend a lot of time and money tuning a factory exhaust system to match the characteristics of the engine. There are two prime factors which are screwed by someone tinkering with an exhaust.
Back pressure is deliberately created in exhaust systems to increase the torque of the engine at lower revs. If you replace the exhaust with an open exhaust that doesn't have this back pressure the engine will generate less torque at lower revs and more torque at higher revs. This means you have to rev the nuts off the engine to get anything you can really use.
Widening the exhaust causes the exhaust gases to expand prematurely and cool down, making them denser and less free flowing. Attention could be paid to TVR here, who even on their 5 litre V8 engines only have two 1.5" bore exhausts coming out the back of the car. TVR know a thing or two about tuning exhausts ;)
Blitz Turbo Timer The turbo timer keeps the oil pump and engine fan running after you remove the ignition key. The oil in the turbo is often run at very high temperatures and if you stop the engine without letting this oil cool down it can boil on the turbo vanes and cause corrosion. You REALLY don't want corrosion in a piece of metal spinning at several hundred thousand rpm ... ;)
Turbo XS Boost Solenoids With Manual Switch Mounted On Dashboard. (High Boost 17psi-Low 10psi) This is just a switch to control the limit of the turbo. There will be safety valves attached the the turbo exhaust input (called waste gates) which let exhaust gases bypass the turbo (and hence let it slow down and reduce intake air pressure) when the intake air pressure rises too much. It's a safety system.
TRD Dials With Traction Control Traction control is an electronic system to back off the throttle when wheels start spinning. Some systems are awful, some are absolutely amazing. I have no idea if this one is any good.
Apexi Racing Supension Set-Up This is where, for me, the car turns from a slug into something undrivable. The tarmac on race tracks is incredibly flat, like an airstrip, and the suspension is there to keep the car level, not to soak up any bumps. On the road it's a different story with pot holes, drains, cats eyes and seams in the concrete. Hitting any of these items in a car with racing suspension is likely to hurt and cause intense tiredness when driving long distance. And then there's speed bumps...
Personally I wouldn't go for it unless you were looking for a track car. I like fun cars but they have to be serious road cars and not something that I'll hate to go to Tesco in...
