CB Dry Sump

Hey guys
So got all my Cb Dry Sump Stuff thanks Greg ;)
So Pete or anyone that can Answer this...
Do I need a shut off on the Inlet Side of the Pump to Stop the Oil
from going into the Motor when not running?? also how will I know
I have a good oil Level if I can't use the Dip Stick...
and anything else that I should Know, b/c this is all NEW to me :)
thanks guys
Chris.
Sorry to get in so late on this conversation.
I'm running the CB DS pump on my T4, and my tank is mounted behind the drivers seat. It holds about 12 litres of oil and the bottom of the tank is about 2" off the floor. I still needed a ball valve as mine is not a daily driver ... just remember to open the valve before starting it up.
I used -8 AN to plumb the system, no issues at all, and this includes plumbing an RX7 oil cooler at the front beam. The RX7 cooler looks like it was meant to be there, just the right width and height, and has an integral thermostat.
You check the oil level by looking in the tank, but check the level when the engine is running, like already previously mentioned.
I drive the bug hard, and oil pressure at hot idle was about 15 psi, max pressure was about 60 psi, 7200 rpm. The engine sump may have a little oil in it while it is running due to the small scavenge, but no big deal ... the issue is constant oil pressure while driving hard and cornering hard.
Princess Auto has 1/2" JIC fittings for 1/2 the price of -8 AN aluminum. These are equivalent.
Looking great Chris.

Have a pic of that oil cooler mounted?
I'm trying to mount a Benz cooler to the split's beam. Not fitting well.
there is no golden rule on how much oil should be in the tank as long as the engine always gets oil, especially at high rpm when the oil is hot and the pump is spinning at full capacity
- always top up oil tank levels with the engine at operating temp, otherwise when the oil heats up and expands it will overflow everywhere
- the more oil that is in there the longer it wil ltake to get to operating temp, run an oil thermostat, and an air one on the cooling fan if you can (still takes me a while to warm up)
- as a point of reference my 911 takes about 12 litres of oil, as did my gold ghia
- I had a shutoff valve on my ghia but be careful, mine partially shut on me while driving! I would remove the lever off the ball valve and use it as a key to shut of fthe oil.
- oil feed line should be huge an12 or bigger if possible, that line is like 1" ID on a 911
My beef with the CB dry sump pump is that the scavenge side of the pump is not much bigger than the feed, I beleive that it should be bigger with all that hot frothy oil in the case, mine was filling up with oil when I had a cb pump

thanks for the Info :)
Ok I'll Keep an eye out For the OverFlow,
But on the CB website it's saying to use all -8 Soo that's what I
have already bought and have the lines pertty much made up
Will See when the time Comes when I Start it up for the first time...
lol
hey Pete thanks
Ok So I have Placed it behide my Driver Seat have to Keep it Low
in the car, to keep that Center of Gravity Down ;) (I'm such a racer)
Ok so I'm not getting what your saying about the oil Level
how can I tell when the System is Full.... like what will the reading
on the Dip Stick....
Anything else that you or Sandeep or Bry would Be Great
thanks guys
Chris.
You check the oil level by looking at your oil level in your tank.
If you want to check the motor, need to check the dipstick when its running. But it may not show either.
By dry sumping, your always sucking the oil out of the motor. So if your oil pressure is fine, and your oil tank level is good, your dipstick could show emtpy. Your tank is now your sump.
If you fill the engine with oil to the marker on the dipstick, AND fill the tank, you'll drive down the road and the tank will overflow as the oil from the engine will dump to the tank. Look at the Autocraft/Pauter dry sumped engines, and you will see the cases are flat underneath with no oil sumps.
just some pics
it's not all done but 3/4 done...
looks nice, I like that pulley
Your tank looks like its a good 6" lower than Pete's, are you sure you cant get it any lower? The lower the better ;)
Not sure what you are going to run on your alt, but if you use a 356 upper pulley you can gain back some of the cooling fan speed you lost by having to use the smaller lower pulley.

hey
thanks Bryan For that timmbit of info on the top pulley...
and Ya I would have Love to put it on the Floor but just don't have the room... and they are Starting to get thin LOL
Chris.
Where did you get the AN fittings from?
Hey just a performance Shop in town here...
performance improvements I deal with them for a quite abit
Soo I know they give 10% off to Car club, So next time I'm in there I'm going to See if they can put are group Soo then everyone that
goes to one can just tell them and Boom 10% off... :)
The tank looks nice all shiney!
You should spray bomb your interior metal to clean it up a bit........
yaaa I love it Shiny :)
I am Planing on Doing that just waiting for Better weather
going to Scrap all that Shit off and paint it then just run that for the Summer, maybe have a Scraping Shit Party and Beers and BBQ lol anything that you can sagest to remove it?? then all Body work and New paint over the winter... and maybe a Cage :)
Hey thanks
I knew that the tank is for the oil and that my motor doesn't have any in it just wasn't sure how to check the oil level that's all...
Chris, I know you need a shut off valve. Pete had one, I remember him telling me. I'm sure Pete will jump in with anwers on the oil level question.

Because stock sucks.
I had a shutoff valve because it wasn't my daily. It would sit for awhile and the oil would make its way though the oil pump and fill the engine. My tank was way higher than the engine, on the rear shelf behind the seats. I'd also close the valve when parking overnight.
I checked the oil when it was warm and running. Watch you don't lose a finger on the fan belt. It will show a different level either Hot or Cold. Keep a eye on your idiot light, and the tank level when starting out.
Sandeep, and Bryan are running drysump setups too.
