I thought it does, unless for some reason its changed. If it wasnt then a part number of what to order should have been included. It's a 2.5 or 3 bar map sensor.
They really must have changed things then...the one I bought used had all that and the previous owner said it was all in the kit he bought...huh
I really dig this idea, but I just dont think the room will be there after the turbos are installed. I mean there is nothing.Found it...
Your continual push to go in your direction, find a new approach, and innovate is ways refreshing Zack. Part of the reason I liked this forum so much. We V6ers are glad your back over here with us lol.
Haha I'll take that as a compliment!
The only explanation I have heard that makes sense to me as to why the drain has to be above the oil level is that the oil which drains out of the turbo isn't exactly liquid but more like a whipped frothy foam and that it basically floats on top of the liquid oil so you need a large surface area for it to spread out otherwise it will back up into the turbo.
I agree with everything you said. However, during my research I have found a consensus among people I would consider experts at turbocharging that it is not a good idea to plumb the drain lines below the oil level. I could not wrap my head around why, the level in the lines should never exceed the level in the pan so what's the difference? Finally I found the only explanation that makes any sense to me, and that is that the oil "froths" effectively increasing its volume drastically causing it to back up into the turbo. Now in the video you posted the engine is not reving very high or for an extended time so I'm not sure it's a good representation of what the inside of those lines would look like after a 20 minute drive down the highway.Now check out this diagram and note where it depicts oil level... Obviously it is just a diagram but it is taken from official CAD models. Supersix's oil returns are just barely above oil level from what I can tell. Also note just how high the manifold is from the oil level (the turbo drain is about level with the exhaust manifold location) That is a very long stretch of pipe before you get to the turbo. So as long as the oil pump is pulling more volume then the turbo can drain (pretty safe assumption) then it should be perfectly OK to use the drain plug as a turbo oil drain port.
I can't really see the oil foaming that much to cause an issue. The design of the turbo would be heavily effect this along with the size/diameter of the return line. The drip tank idea would alleviate any possible issue though providing a larger volume for the oil to expand and to provide an atmospheric vent to alleviate pressure.
Like I said I don't understand why, but literally every reputable source seems to be in agreement that it's not a good idea. There were many explanations given, but this is the only one that makes sense in my head. Taking this explanation at face value, to be safe in my mind the tank would need a large horizontal surface area so that the foam could not cling to the sides.
Yea I would love to know why people say it is a bad idea.... I understand that it is just safer to put the drain above the oil level but I just do not see a reason why it cannot work as long as the turbo is high enough.
I can't wrap my head around it either, but I'm old enough to know that if someone has been doing something competitively for over 20 years and virtually everyone who should know agrees, than they are probably right about it.
