919 blade waterpump
If i remove the water pump and take out the impellors how on earth does this then work the oil pump?, as they are attached to the shaft that works the
oil pump.
Got a booster water pump and it recomends removal of the water pump impellors, answers on a postcard.
Thank's, Joe

Any chance the instructions are for a 893/929/954 and don't apply to the 919?
Sorry I've no other ideas

The water pump takes its drive off the oil pump I think so the water pump relies on the oil pump, but not vice versa AFAIK. The water pump is in the
external casting bolted to the engine and can just be unbolted and withdrawn from the engine, and Im pretty sure you can ditch the entire water pump
assembly and just block up the hole and it all works OK.
A mate of mine ditched his water pump so he could run a reverse ringgear off the output shaft, here's a few links to relevent pages on his
website.

Thanks Chris, so in theory i can take out the inpellor shaft and stick the empty pump housing back on.
Might give it a look then Ta.

You could, but you'd need to make sure no oil escaped down the hole where the impellor shaft lived. Alternatively do as Ed did in the links and
ditch the pump assembly completely, blocking up the hole with a 1.5" core plug, saves weight and reduces complexity.

I can't see where the water goes once you've blocked that hole up?
Is there another outlet on the blade?

The water doesnt come out of that hole in the block, the hole is simply to take drive from the oil pump.
The water pump casting itself has an inlet and an outlet, so if you discard the water pump you just join plumb your electric water pump in its place,
or join the two hoses together if you have positioned the electric pump elsewhere.

Electric water pump
I have done this converion a number of times. Chris is right the oil pump is driven by chain off the clutch shaft - so no probs there. Remove the
water pump, split the casing and remove impellor, weld up the shaft hole and refit. In order to plumb electric pump you will need to add some T -
Pieces to the outlet side, then simply re-hose. Large outlet feeds to 25mm on front of block, Fit a 25/25/16 T in this line and take a 16mm line up to
the remote stat housing and you should be in business, not only does it improve cooling but its worth a few BHP as when full of water the pump takes
some driving. It was a common sidecar mod when I was racing. I would strongly advise wiring the pump direct into ignition live and avoid any
temptation to fit a switch as I have seen people forget to turn them on. If you run into difficulties give me a call on 01449 736633
regards
Andy

Cheeres Andy, i need to get a new pump today as the 36 tonne hydraulic press broke it .
I gave it a tweak too much trying to get the shaft out.

Hi guys,
anyone had any luck using EWP's from production cars such as the audi/vw or even BMW? booster pumps.
My physics are weak but I have worked out that the smallest Bosch booster pump only transfers 8.33 litres per minute, where as the Davies Craig units
max are at 80 litres for up to a 5 ltr engine? Surely a little old blade wont need that sort of throughput?
Any suggestions. I have sourced a good condition booster pump for £11 and wondered about fitting two or even three at different parts of the water
system, increasing reliability of the pumps at the same time through redundancy?
Always on a budget 
a small booster pump from various audi/vw's have the following specs -
Bosch PAA -
Nominal voltage UN 12 V
Delivery V 500 dm3 · h–1
Delivery pressure p 0.1 bar
Direction of rotation R
Type of duty S 1
Degree of protection IP 5 K 0
Weight approx. 0.4 kg
Part number 0 392 020 024
A larger pump is available at 1200dm3 which is around 20 litres a minute, but I cant find out which production car it features in..
Cheers
Paul.

Stick the Bosch part number into ecat and it'll tell you which engine/car its been fitted to.

FBI - thanks for the link... it was used in almost all the Peugot 405's from 92-96.....
As for flow rates, anyone know/willing to guess at what the minimum flow rates for a Blade would be...?
I am getting the feeling that there isnt a locost way to replace my water pump to get those last few bhp?
cheers
Paul.

Several people on the Yahoo list have experimented with OEM EWPs, I think one off a Corrado was mentioned but Im not sure as it was a while ago.
There's a link to the Yahoo list in my avatar below if you want to go and ask, a chap called Gordon Griffin is your best bet
