Sump System Information
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
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,
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 all our dry sump pans, where you can fit an external crank sensor, this allows you to use one of our small trigger wheels and pulley, which get rid of the need for the internal pressed steel trigger wheel which can be fragile after extended use or on high revving engines.
Please look at the dry sump systems on our website checking to see which one is most suitable for your needs, then contact us directly and we will advise you further. The more information you provide us with, the better our help with your choice will be and we can advise you on what alterations or modifications may be required, when installing a dry sump system especially as most installations are different.
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.
