has anyone used a 12V turbo bearing oil pump for the motors total use.. 3.2 GPM ebay like $135 |

While I've always liked the idea of an electric oil pump, I've never seen one that had the pressure & volume capacity (or durability) for primary oiling. If there was then it would pull alot of electrical power to do so. Those "turbo" pumps are designed to scavage - pump return oil from the turbo back to the pan under almost no pressure. Don't sound like it'd be enough for what you're thinking of. There's a reason that all the OEM's have stuck with mechanical pumps, even if a few are variable displacement. It's one of those things- if it had reasonable gain vs cost then car makers would have explored it at least somewhat. Look at electric P/S, cylinder disabling, or any one of the many crazy valve timing/ control technologies that are out there now. |

If you want a more durable oil pump you're going to have to shell out for a cam or belt driven pump. Go look at a 2hp electric motor if you want to get a rough idea of what you'll need to keep up with the full oiling requirements of a slant. At 746 watts/hp, 2 electrical hp is 1492 watts/14.5 volts=103 amps. That's at 100% efficiency too which doesn't happen. |

If you can make it work then try it out & report back. Like I said, I'm interested in the idea but I don't see how it's do-able. You need a 12V pump that can move hot engine oil (at least 250*) at something like 4-7 gal/min at 60psi- & you need to controls for the pump. & it has to be reliable. (that's ignoring electrical supply for right now. I wouldn't want to think of what tech inspectors would say about having a running gas generator set in the trunk of a race car) |

not saying I want to build it,, but would be an interesting concept to leave the slant six oil pump exactly where it is mounted to the block currently, but eliminate the cam drive and run the pump shaft the other direction, through the pump cover and install an external direct drive DC motor on the shaft, could modulate the DC motor with rpm's ... likely problems would be ... not enough room for a motor big enough to spin the pump from the stopped position, the DC motor would certainly add weight compared to the gear drive, added complexity of wiring and pump speed control... |

All I could find after a quick search was a magazine aritcle on SBC oil pumps- they averaged 5.5-8 GPM. Since there was stock & high volume pumps in that test, I went with a lower number . Point is until you know exactly what you can "get away with", you should certainly consider getting a pump that's overkill for something critical like engine lubrication. |

Didn't Mark (Madmax /6) run an external belt-driven pump on his motor? |

Yes, he runs a Dailey Engineering belt-drive pump. http://www.daileyengineering.com/
