Hey Guys,

Currently going through my build and I'm going to be making a Oil Tank soon. Plan Is to be about 500mm Tall and about 220mm in Diameter. so it would be a 10L tank and that means that i will be able to run approx 7L in the tank. My main question is Tank Location, Does the tank have to be above the pump pressure side inlet so that it will gravity feed or will it be okay to run it level? My plan is to run in behing the 'B' Pillar of the roll cage. After doing some corner weighting with me in the car i need to add some more weight to the back LHS. But i dont want to be having to run a oil hose upto the tank if it has to be half way up the rollcage.

Cheers for your help guys

Yes but from fluid dynamics, the longer the pipe the more the pressure drop.

It isn't pressurised. It's just a header tank for the pump that is in the engine bay.

As stated above. Place in the boot, on the left. Purpose of this is for the best weight balance when corner weighting.

Yeah the fluid between the tank and the pump is under no pressure at all its only a gravity feed to the pump.

Yeah that was the idea just wasnt sure we have corner weighted it an we have moved the battery placement further back and the firebomb back so adding another 15kg to the back pass side will be awesome for corner weight. My main concern was having oil get to the pump but solong as the pump is below the oil level in the tank and no part of the oil line goes above oil level in the tank gravity should feed the pump no problem

No, not my car mate, just an image I've pull off the net.

All the supercars run that style setup.

Fit a electric oil warmer in the tank too, just plug it in 1hr before you want to start, and bingo, warm oil ;)

Bringing this back from the dead abit but you guys had a fairbut of knowledge on the dry sumps. Obviously pump at the front tank at the back. How would i go having an oil filter on the scavenge line in the boot then a cooler then into the tank? or is it best to have the cooler and filter closer to the motor?

No, the filter should be on the pressure side, before your expensive engine.

So you'd plumb in a filter like this:

Pressure out of oil pump--> remote mount oil filter--> oil cooler--> pressure into engine.

I have a filter between engine and dry sump pump and another filter between the pump and the tank and thats all on the scavenge side then a filter on the pressure side of the pump between pump and engine so 3 filters all up

Question is whether the cooler should be 1. on the scavenge side; and 2. in the boot.

Presumably the tank and lines are going to punch out quite a bit of heat. Depending on length of events being run, oil temps may not need to be regulated with a cooler. Any heat exchanger will need to be getting airflow - maybe the oil tank could benefit from a bit of air passing around it to evacuate heat also.

      That's not a transistor --- it's marked ZD1 which makes it a zener diode. As to what the breakdown voltage is, not enough there to divine.

      R34 GTR Seats / No longer reclining

      By bilbo117 · Posted

      Hi all, Long time since I've posted here. Looking for some advice on what I can remove to further identify the cause of my issues.  I can move the passenger seat forward and back but the knob used to adjust the seat angle is pretty much free spinning, there's very little resistance.  Removing the side cover I can see that the chain is intact but the shaft for the adjustment spins without the gear attached to it moving.  What's my next step for disassembly here? Is this a common fault? Just being a little cautious as I didn't want to start removing bolts for a spring to fly out or something equally as stupid.  Cheers

      Ethanol Content Sensor - Always at 11%?

      By joshuaho96 · Posted

      The incentives are mostly the same, yes. Ethanol is cheap compared to the cost of doing 98-100 RON with crude oil alone. 87 to 93-94 AKI all with E10. In 2020 Canada mandated E10 as a part of their "renewable fuel standard" and is supposedly going to go to E15 in 2030. In California where there are only 8 refineries with two threatening to shut down next year it's been over 20 years now of E10 and 91 AKI maximum because there's just not enough refinery capacity or crude oil supply relative to the demand for premium unleaded fuel. And CARB's low carbon fuel standard means functionally none of the diesel available at the pump is made from crude oil anymore. It's almost all entirely 20% biodiesel blended with 80% renewable diesel (hydrotreated vegetable oil) now. The number of gasoline vehicles that support E15 or higher ethanol concentrations is surprisingly low, I can't imagine it being wise to play tricks like this without flex fuel sensors in most of the fleet.

      It's almost certainly the same as the one next to it.

      South Australia, which is hardly as far behind as the rest pf Oz makes out, and who is also not a paragon of progressiveness (read that as over-legislation) in the area of vehicle standards, has this to say on the subject: Adjustable coil-over suspension Aftermarket adjustable coil-over suspension components are suspension units that incorporate an external thread on the main body and corresponding threaded spring saddle that allows the vehicle's suspension height to be varied. If fitting aftermarket or coil-over suspension components you must submit an Application to modify a light motor vehicle form and a report from a light vehicle engineering signatory (LVES).
