The Gated and Baffled Sump

For the past few years, we’ve been sharing information with lotus twin cam owners about how come to grips with the problem of controlling oil surge.

Oil surge at it’s worst, is potentially the most evil thing that could destroy your expensive twin cam engine in a matter of seconds.

Oil surge is caused though “G” force loads created during cornering, braking, and to a lesser extent, acceleration – the oil in the sump is forced away from the oil pickup pipe, and the standard orientation being biased to the RHS towards the front of the sump does not help in any way, so when starved of oil, the pump will suck air for a few seconds, interrupting oil flow, quickly followed by oil starvation to the main bearings and con-rod bearings, and potentially followed by that unwelcome metallic taping noise, and at it’s worst, possible ventilation of the engine block as a con-rod or two part company. (Worst case scenario)

In order to explain more about the gated and baffled sump, we have posted a couple of videos to help you understand more about the building and fabrication of The Gated And Baffled Sump For The Twin Cam Lotus Engine.

You might possibly learn enough from to go ahead and build your own, (and that’s great) but then, there are some intricate things that you wont know about and you need to know and understand about how these gated baffles really work, and to understand the tricky details. But you can get all of the nitty gritty in the How To Build A Gated & Baffled Sump ebook, it is well worth the few dollars you will spend.

But first off all, take your time to view the short videos below, they are short, sharp, and to the point.

This modification, if done correctly will spell the end of oil surge in your twin cam Lotus engine.

If you compete in historic racing, chances are you wont be allowed to run a “dry sump” lubrication system, in that case the gated and baffled sump will be nearly as effective and giving equal oil delivery to the pick up pipe and pump.
