Dry
sump systems & Accessories
If you do not already know the advantages of dry sump over a wet sump engine, they are as follows:
1. Wet sump requires a well of oil, which needs to remain in contact with its pick-up pipe, which supplies its feed to the oil pump, itself. Unfortunately the needs of motorsport usually require that the engine is mounted as low as possible in the car and therefore, the sump pans are usually restricted in height. If you take this to its extreme, in some of the pick up racing formulas therefore, you effectively end up with a sump pan that resembles a frying pan. So, as you can imagine when the car is cornering at high speed, the thin layer of oil e.g. 1" to 3" of oil is sloshing around continually. In order to make the sump pan work, it needs to be quite complicated with gates, to keep the oil supply continuous to the pump, without any pockets of air being supplied instead of oil.
2. The nature of a dry sump system is that the pump, which is usually in three stages, is designed to do two things.
a. Supply a continual flow of oil from a very tall thin tank (which is the reverse of a wet sump) and since the tank is tall and thin, when the car is cornering a high speeds there will never been a gap in the supply of oil to the pump. |

b. The other two pumps are designed to extract the oil from the sump pan and transport it to its oil tank. This does two things, firstly by removing the oil from the sump (the better the sump design, the better the oil is removed) and transferring it to the oil tank. Secondly, because the oil has been removed from the sump, this means during cornering the oil that would have been sloshing around in a wet sump and slowing your crank down, losing you horsepower, is no longer there. |
Some of the other benefits that can be gained from using our dry sump systems, which are specially manufactured for us by Pace Products, is that on the high specs of pumps, the scavenge stages are large enough to generate a vacuum. This allows you to do two things, first of all remove all the breathers from the engine, which means less plumbing and a neater engine installation. In some cases we have even seen BHP gains due to the fact the engine is running in a vacuum.
The dry sump systems we supply will suit almost every type of car you can imagine, front wheel drive, rear wheel drive mid engine cars e.g. Westfield's, Caterhams, Mallocks, Vauxhall Lotus, single seater, Astras & cars with cross members in the way. Some systems have lugs at the front to mount the engine directly to the chassis of the car some have rear legs to allow attachment to a bellhousing or adapter plate, fins are also fitted on some versions to protect the flywheels. There is also a mount fitted to the front of the higher spec sump pans where we can fit an external crank sensor pick up fro use with high revving engines.
If you don't find a system to suit your needs please give us a ring as we can usually make one to suit your requirements.
What you get in your kit
Every system contains:
· Three stage pump with pulley
· Mounting bracket or front cover*
· Sump pan
· Sump pan filters & fitting to couple sump to the pump
· Pipes & hoses from sump to pump
· Drive belt & crank mounted drive pulley
*Note The mounting bracket allows the dry sump pump to be mounted on the exhaust side (PWR power steering pump side) of the 2.0L & you retain the original oil pump housing removing all its internals using it only to feed oil into the block. The front cover type is designed to replace the original oil pump completely and we have designed it in such a way that the dry sump pump can, is mounted on to it. The dry sump pump can be mounted onto either intake side (ALT alternator side) of the engine or the exhaust side (PWR). The preferred option is the exhaust side.
YOU MUST SPECIFY UPON ORDERING YOUR KIT WHICH SIDE THE PUMP IS TO BE MOUNTED BECAUSE THE SUMPS ARE MACHINED TO SUIT & CANNOT BE MODIFIED LATER.
