It's time I moved out of the dark ages and got myself a dry sump system on the rallycar. What's everyone using? Any pictures of installations? especially with the stock cooling. My concern is that I'll have to do some major surgery on the fan shroud (4 cylinder engine) as any dry sump pump will sit so far proud that I'll have to cut a hole in the fan shroud. Really interested to see what everyone has done. (IMG:style_emoticons/default/beerchug.gif)

I use the CB 2 rotor pumps.
The front inlet and outlet ports are a bit too restrictive imo, and the fittings/hoses will interfere with stock 914 engine mounting brackets. The pump gears aren't that long, meaning they don't move a large volume of oil, so I do everything I can to improve the flow wherever I think there's a restriction in each port, chamber and orifice of the pump. The brackets can be clearanced but it will still be tight. I'm pretty sure the cooling shroud will fit but it will be nearly impossible to attach/remove hoses at the pump once the engine is fully assembled. |

Do you get additional HP by running a dry sump oiling system? And if the answer is yes, how much on a Type IV? |

I would estimate 8 to 10 hp at the upper range of the rpm. Which is okay in my book, because oil has two jobs in our engines. Lubrication and cooling. It would be well worth it, because all of the check marks are on the positive side, even with having to manage 10+ quarts of oil. |
