Accusump install

[AZ986S]

OK so I promised I would get some photos from my Accusump installation in the tunnel. IMHO this is the best spot to put it if you can. Out of sight, doesn't take up any trunk space, doesn't heat up up the ECU etc... The only compromise is that it is difficult to access it and hard to see the gauge on the air side. My thought is to put a remotely mounted gauge using an electric sender, probably in the cabin.

So here are some pics:









Here you can see the 2 hoses going around just behind the motor mount enroute to the remote oil filter:



And this is the remotely mounted oil filter. It is located on the passenger side, next to the water pump, on the upright wall. There was just enough room to mount it there with a Napa Gold 1042 filter:



I haven't used it on the track yet, but I'm heading to Inde Motorsports Ranch in Wilcox, AZ on Labor Day weekend. So the way I use it is I power up the Accusump master switch just prior to starting the engine for a few seconds in order to pre-oil. Engine starts soooo much smoother. This has got to be good for reducing startup wear... I then turn it off and let it recharge during normal street driving. If I leave it on, it will start dumping at every stop or light.

Here is a photo of the gauge and panel I custom made.



I have 2 switches: 1 for the Accusump and 1 for the radiator fans (high speed).
The orange pilot light on the bottom portion comes on when the Accusump is dumping (solenoid valve open). The left gauge is for oil temp, sender mounted on rear of the driver's side head. The right gauge is the oil pressure, sender mounted where the original pressure switch was mounted (passenger side front of head). These are VDO gauges. I originally wanted to install the Speedhut gauges, but they wanted 5 weeks to make and deliver them...

I tried to match the gauge bezel color with the instrument cluster gauge bezels (chrome), but the gauge bezels protrude way more than I like, so I might have to redo the faceplate with 48 mm dia holes to flush mount the gauges.

I wired the existing oil pressure switch wire that goes to the instrument cluster low oil pressure warning light in parallel to the oil pressure gauge warning light, so they both come on when oil pressure is below 7 psi. The issue I have now is that the lights come on when oil is at temp (190-200F), whereas it didn't before, so I assume the original pressure switch is set to something less than 7 psi.

Now that was annoying me, so I upgraded to latest oil pressure relief valve and spring, thinking the low oil pressure was caused by a broken spring or bound piston. On the upgraded parts, the spring is slightly longer and the piston has the bevel on top, but the old piston and springs looked just fine.

After installing this, no difference in the oil pressure, still around 7 psi at idle. I ordered 10 L of Motul 8100 Excess 5w40 oil as I have read that it is a very good track oil and it will probably bump up the idle pressure some. More to come...

I'm jealous that you can mount yours in the tunnel. My only critique/suggestion is that I've found it helpful to check the pressure in the tank every once in awhile. I'm having issues with my release valve and have had to look at the gauge to see if the tank has oil in it. With your gauge down underneath it might be difficult to see

I'm happy I could put it there too

I don't have room for a third gauge on my custom made gauge panel, but I could likely put a small LED pilot light wired up to a 5 psi pressure switch mounted on a tee where the accusump air gauge is. That would tell me I have low pressure on the air side, but would not give me realtime pressure... Do they make a WIFI pressure sender? Would be nice to have that on my phone.
