In order to get the most out of our DC5 we have to be able to adjust every setting you can think of. When project dc5 was being build BC Racing did not have a coilover set available with external reservoirs and rebound damping adjustment. That’s when it comes in handy to be the BC Racing distributor for the Benelux, when it is available you are the first to know about it. Therefore out with the old, in with the new! Well……OLD…..the BR series only covered a few laps but only the best is good enough.

BC Racings premium flagship coilovers are the external reservoir ER Series with separate compression and rebound damping adjustment. The ER Series coilovers bring with them the high quality and unique features seen on the BR  type but have the additional benefit of external reservoirs and the ability to allow you to individually adjust and set compression and rebound damping rates. The external reservoir ER Series coilovers allow BC Racing to increase the oil capacity of the damper unit. The additional oil capacity reduces peak oil temperatures which decreases variations in damping rates due to oil viscosity changes. The reduction in damping rate variations improves handling and ultimate on road and track performance.

We sure had some fun during our first testing day but it soon turned all around.

28th of August a new event came up. We were desperately trying to get the car ready before that. Some last details still had to be done but no major stuff. We had to make sure the car was running properly so we didn’t lose face during Superlap so we planned a shakedown on Zandvoort circuit.
August 24 was the big day!!
To get the car really ready for track we still had some things to do. It was way to loud with the Ape garage custom exhaust, this should only take one lap before we get the black flag. Regulations are very strict over here in Holland according to sound levels. Another problem was a ticking fuel pump. That should be the first problem to take on. After that trouble really started.

A few weeks ago we had a photoshoot with our lovely ladies for a new poster. And sure we like to share

To create enough downforce on our track car we decided to make the entire bottom flat en use a rear diffusor. The diffusor is made of ABS plastic to keep it light and flexibel.

After searching the Showoff Imports warehouse we found the best air filter to suit our project. A group M like filter system, this should do the job of feeding the K20 with enough air.

Than there is the massive Megan Racing high capacity radiator. After welding some AN-connections (yet another custom job) on it we could use braided hoses with AN-fittings. Together with a Meziere pump this cooling system should be in enough to keep everything “cool”. The thermostat has gone so we always have full cooling capacity. During the filling process we discovered some leaks, after fixing that we thought we were all good. Yupz, we thought. There happened to be a major hole in the back of the engine. After comparing with the k20 ep3 it came obvious. There used to be a heater connected to that hole. After market plugs are available only from one brand, and we needed it fast, so that wasn’t an option. The best solution in these cases is to make one yourself, nothing can beat that So there you have it, one custom k20 heater plug. Only available at Showoff imports!!!!!!!

We don’t need any oil to get into the our engine we need a catch can to keep the oil from getting sucked back into the engine. For environmental reasons we need to catch all access oil the engine is spitting out.

In order to go “green” being a hot item in motor-sports, we decided to run the car on E85 bio-ethanol. Well, to be honest, it runs better and adds a few hp’s.
The entire fuel system needs to be upgraded. Bigger injectors (650cc), swirl pot to keep the fuel from getting hot and make sure it takes fuel and no air, new fuel lines and a fuel pressure regulator. I will take you trough the system. First we pump the fuel into the swirl pot with a small fuel pump. No need for a big pump, it just keeps the swirl pot full. If the swirl pot is overflowing the fuel just gets back in the tank. To pump the fuel from the swirl pot to the front we use a Bosch 044 fuel pump. Before it gets to the fuel rail the E85 runs trough a filter. Right after the fuel rail there is a fuel pressure regulator, needed to keep the whole line from the pump to the fuel rail pressurised. All fuel that doesn’t needs to be injected runs right back to the swirl pot to cool down and ready to be used again.

In the chapter “a bitch called electronics” the end is near but still, we need some more wires to connect. We are using a race technology dash so it needs some more sensors. Oil pressure, oil temperature, fuel pressure and fuel level are a few of them. Also to navigate through the dashes menu a couple of buttons on the steering wheel are needed. And of course, the starter button. Originally the dc5 doesn’t have a starter button, we ordered an S2000 starter button. The wiring was already adapted in an earlier stage.
