When I had my stroker four I used Autocraft, three stage, two suction, one pressure. It would draw such a vacuum at 6K RPM it would suck the cork valve cover gaskets in. If you use one run dash 12 or 16 suction lines.

Thanx for the heads-up Aaron.
Hey John...why three stage pump instead of two stage? Also what do you know about the 2 stage style pump that uses the stock(?) pump with a machined aluminum second stage mounted on top. Mounts in stock location. |

We used the two suction model as we wanted to suck the oil out of the valve covers (allooy bolt on) and the sump instead of letting the oil drain back from the head area. There were suctions on each valve cover bottom and they went to a tee that went to one of the suctions. I used an Autocraft aluminum sump plate with a 90 degree AN fitting welded to it as the main sump cover. Since the cover had multiple bolts we had to modify the case which was done when the engine was apart. The other big issue was making a new front engine mount since the pump was pretty large and dash 12 lines take a lot of room. We used an empty case and tranny to do the fit up work for everything as things had to come in and out frequently. In the end the dry sump system was a big help for engine life.
There used to be some picts on the Type IV forum or somewhere that showed some valve covers with clear inserts inside and they showed the oil level in the head area at various RPMs. At 6K RPM they were full! |

When we were running E production in an 1800CC 914 ( 1998 region champ BTW) we bought a three stage pump. These were used in F superV when they used air cooled engines. Three stage was OK for them because slip streem cooling was used and no fan shroud was needed. Three stages would not fit under the shroud. My son had the pump cut down to two stages which will fit. We never used the pump and I still have it. Let me know I'll email you pics. Al ljgmere@aol.com
