The Greddy kit for the RX8 also runs the drain through a banjo-bolt in the stock oil drain plug location. You don't get much lower than that.

ahhhhhh hahaahahahaahahhahahahhhahahaaahhahhahahhaahahaha


tell them that they need to T the drain line to their compressor inlet. that will provide the syphon action needed to get the sweet oil drain action going!

Interesting. I take it that the pump is pumping the oil through the engine as fast as the oil drains through the turbo? I guess the level in the oild drain pipe will never get any higher than the level in the pan? Please explain, all the "turbo books" say otherwise but I have an open mind and lots of respect for the hands on approach.

Don't forget oil flowing to the main bearings, cam bearings, (oil cooler). So it's not like you have to account for 100% of the oil coming down the turbo drain, only a fraction of it.

Gravity will keep the two levels the same.

Thanks,
ok,

I see, the same amount of oil being diverted to the turbo comes back at the same proportion. I guess a long drain tube gives a margin of error when going down hills, ect. right?

Only if the two fluids are of equal density.

we've tapped ls1 pans low, used the oil level sender hole too. All caused smoking issues and seals leaking due to drain issues. No matter the size. gravity feed above oil line with no weight holding the oil in the drain works best.

Atleast thats for us LS1 guys with gravity drain.
