Non-BMW Stuff on a BMW Forum

The ratio is not fixed because it changes based on the compressor dimension bore x stroke will change the compression ratio. But it is usually somewhat higher so i would think it would be fine, also I saw on craigslist several portable tanks for cheap (usually old oil free air compressors that failed and the compressor is removed) I got my 30 gallon upright tank for 20$ and it is a nice wheeled one from a craftsman compressor. I will try to take some pictures of how I plumbed it to be easy to fill and then use the air, just having it between the compressor and my tools eliminates a lot of moisture at the point of use because it has time to cool and condense.
I'm likely picking up that Speedaire compressor and my Dad has a 20 gallon tank sitting in his shop that he doesn't use. I'll build a little rack for the compressor and tank and plumb them together with an inline dryer. At the end of the day I'll have an oil-lubricated compressor with about 40 gallons of air. Should be sufficient to do what I want with it. It will also be nice to get some air tools again.

Awesome, that will be a good setup. It will have no trouble running impacts, die grinders etc all day. The right tools sure speeds up projects.
Any benefit to using pipe VS hose to hook the two tanks together? Obviously using some short sections of hose and fittings would be much easier.

This is the building blocks for additional e30 content.

You could, I use hose because it is portable and easily reconfigured. I usually use a pretty short hose between the compressor and extra tank, it flows pretty fast even with a regular 3/8" hose that is 25' long. I like to fill the portable tank and then unhook the hose and drain the compressor. Then I can use the tank on wheels for airing up tires and little things until the pressure is too low and it needs filling again. I would recommend thread sealant like Rectorseal 5 to make a perfectly leak free system. Thread tape can be ok but sometimes leaks. You can get a jar for a couple bucks at my store.

I’ll use regular hose. I’m going to build a rack that will stack the 2nd tank on top of the compressor, so the hose will only be a couple feet connecting the two.
First tank acquired though!

You will want at lease a short section of flexible. The aircompressor vibrates when running....a lot, the expansion tank wont. The vibration load on the connection, if all solid, will cause something to crack at some point.
That’s a really good point. I didn’t think of that. I’ll use regular compressor hose since the distance will be so short.

They really are. I use them pretty regularly. And yes, ‘08 Volvo XC70.

How about some e30 content?
All cleaned up for Road America tomorrow.
Great weather for being at the track. One of the few events I didn’t make it to this year. Hopefully you got to see the F1 cars run. Judd V10s

It was a lot of fun and my girls enjoyed it which is always awesome.
Tonight I got the air compressor hooked up. Not super thrilled with the overall look of it but it will be fine until I redo the garage next year.
I still need to do some hose management, so please ignore the crazy hoses.

Been driving the car to work once in a while and I've noticed that the oil pressure light stays on for a couple seconds on cold starts. I'm going to get a new oil pressure sensor, but I'm just curious what people's thoughts are? It didn't always do this. I remember it turning of instantly - I think even with this engine when I first got it back in.

At least for the e36 its actually in the owners manual that the oil pressure light is supposed to be on for 1-3 seconds after startup.

If you’re worried slap an aftermarket gauge in it for some redundancy

I looked into this and I think I’ll add an oil pressure gauge.
Now I need to decide if I should just go with an oil pressure gauge and do a single gauge pod in the vent or go with three gauges and do the ash tray gauge mount. Probably oil pressure, oil temp, and something else. But that seems like overkill in a stock car.
