| Post subject: | Dry Sump questions for my 1915 |
Since I have no choice but run my 1915 on my rail I may as well dry sump it. I have never used one before & cant find any instructions so I need some answers to the basics. How big a tank do I get? I doubt I need a 5 gallon Nascar tank but is there a minimum? Which pump is best? Are all VW pumps 2 stage (scavenge & pressure)? Do I need to drill & tap oil passages? Any pics & diagrams would be a godsend. I dont want to screw this up. Im leaning towards the CB pump since it doesnt seem to require re-routing the oil passages & keeps the stock pickup tube. Also how do you avoid dry firing the engine since all the oil stays in the tank? Ive tried the Samba for posts but cant get a complete thread that helps me. |

Instuctions will definitely help. Does the tank need to mount high or low? A few posts mentioned oil drainback if the tank is higher than the engine. I also read to put the filter on the scavenge side to keep the motor full flow. Ive been wondering for years....what is full flow?? Nobody has ever explained it in a way that I understand. |

I also read to put the filter on the scavenge side to keep the motor full flow. Ive been wondering for years....what is full flow?? Nobody has ever explained it in a way that I understand. The tank will need to be mounted as low as possible to prevent oil from draining back into the engine and can start coming out of the dipstick tube and rear seal (if not running sand seal) galley. The CB Performance dry-sump oil-pump system is easy, just bolt it on, hook the lines up to it and done, no need to modify the engine at all. You can run 2 filters in line if you want to for extra filtration as long as you put the filters on before it goes into the tank and you can even run an oil-cooler in line as well for extra cooling. I would not put the filter on the infeed side of the pump lines, it should only be a hose directly from the bottom of the tank to the pump (right side) and run everything else from the outfeed of the pump (left side) I would put the cooler first, then filter, then into the top of the tank. I am trying to find a print to show you how it hooks up, it is very simple and worth the $$$$$ Now as far as the full-flow goes, it opens up the volume and lets the engine gets the oil in and out a lot quicker than stock. The stock setup is like leaving all the oil inside the engine (wet sump) and run no filters at all, just a strainer. Full flow is where you tap into one of the oil galleys on the outside of the case on the left side of the pulley and run a remote filter in-line and it drains the oil from the filter back into the oil galley that was tapped into, and that allows the oil to go directly to the engine bearings, it takes a lot of restrictions out of the oiling system and results are very great and very reliable that stock, a must for any mild VW engines (1776, 1835, 1915, all the way to a small stroker) You do not have to do all this by tapping the case if you go dry-sump, it will work the same as the wet-sump full-flow. |

I read on the Samba that the CB pump redrects oil to that full flow passage poorly but doesnt give instructions to improve this but says it can be done. Is it necessary to do this fix??? |

Is anybody running the 6" pulley CB sells that works with their pump? Any problems with it? |

Yes a 6" pulley will work with a cb dry sump pump . If you run the bigger bugpack or autocraft pump you have to run a 5 3/8 pulley |

I had to clearance the back of the pulley and the front upper edge of the pump cover when I put that CB pump on my boy's motor. Been workin fine for a long time like that though. |

I am running the Scat dry-sump pulley and it is 5-3/8" and I don't think the 6" pulley will clear right out of the package without modifications to the pulley and I got a CB Performance pump as well. I got a smaller pulley than stock for the alternator to make up the difference for the smaller crank pulley and it will bring the fan speed back to stock specs if not better. The belt is alot shorter than usual too, it varies on the type alternator stand you run as well. The pulley is not cheap and it runs about $75 a piece and cannot remember where I got it at and it is very well built made of anodized billet aluminum and it is a sweet pulley. I think you can get a hold of Tim at Southern Buggy and he can help you with this. |

WOW thats a tight fit. I definitely gotta call CB's tech line about their pulley before I order it. |
