    TAFC these days.......

    Do most tend to be wet or dry sump oil system deals? External tank, or no tank?

    Any pros or cons to consider for either approach?

    Just curious as to where everyone has migrated to these days.

    Thx.

    Ground clearance is first consideration.

    Agreed. Still, I am wondering where things have migrated to these days in TAFC land. External pump & filter, with 6-8 quarts in the pan, or, external pump with most of the oil in a purpose built external holding/venting tank?

    Some older TAFC's may still be running a wet sump system, but 99% are a dry sump. The trend is getting away from the side by side style tanks and many are pursuing round tank designs which are much more efficient. The problem with the side by side tanks is with no baffling, the oil tends to run away from the pick up when the chutes hit, and in some cases could run out of oil in shutdown resulting in kicking the rods out.

    We call them a dry sump but they are more or less a wet sump with a tank. Most all still use a single stage scavenge with the other section to send the oil to and from the tank.

    To build on Stan's point, TAFC's and 1/4 mile Pro Mods don't have the ground clearance for a pan big enough to hold enough oil. Most TAD's are running 18-20 quarts in a wet sump pan to ensure enough oil keep pressure through the shutdown area.

    Steve Pleuger referred to them as a "damp"sump.
