Thanks, but yes that bottom radiator hose does look pretty strange doesn’t it. It was a proper silicone radiator hose replacement and the end that goes onto the thermostat inlet point is actually shaped to flare out from 35 ID to 40 ID I think the fitting size is, don’t ask me why they can’t just make the radiator and thermostat in and out fittings the same bloody diameter it has me buggered. Then the hose could be the same diameter all the way. The temp sensor fitting is actually only 1 mm larger than the hose ID, plus another 1 mm lip to stretch over but it does make it look well and truly stretched.

Your question before about heat soak, made me think about something else as well. The top radiator pipe to the pressure reservoir, that normally runs around the edge of the engine bay and sits right on top of the air box lid.


Silly idea to me, then the hot reservoir tank is right there behind the auxiliary battery and the outlet hose from the tank runs almost under the battery, then up one side of the battery box, across past close to the turbo inlet pipe and over to the motor. anxiety meaning in hindi symptoms What the hell do they design so much heat transfer around locations that we really don’t want hot like the battery and the air box, air intake and turbo. The only thing I can come up with is that normally these are designed to be used in cold climate rather than hot climate.

I’m not even sure it would be for cold climates. The only real time warm air going into the engine would be beneficial would be for start up and warm up. I think it was more then likely hey we have these parts laying around lets make them work kind of thing when the GU first came out but was never revised.

Yes old Milo is an exceptional beast so is Roothy, but certainly thinking outside the box or body as you say BushRanger7. It is a potential option though and clears up valuable space in the crowded engine bay. Not sure if having the filter so far away has any effect on flow restriction or none regardless of which end of the snorkel it is.

Only down side is the big lump of an air cleaner on top, but I am sure there are ways around it to place the filter in a more streamlined position and direction on the roof rack. I remember another thread DB101 was looking at some neat options for a snorkel and pre-cleaner Ram head mounted across the top of the windscreen.

Fester, I often go through the process a few different ways looking at different options of what would be nice, what is nice but too expensive, what would work but be too big or ugly or get in the road of other stuff. nanoxia project s black Then often quite by accident I will be looking at something else like the unused crayfish cooking pot in the shed and hey you know what that just might fit or work. Sometimes I think of looks but other times I go what the heck and just make something. I’m always impressed by other ideas that people have tried whether or not I like them, it’s always good to see other ideas.

A little bit of progress this week, getting the pipework sorted out and measured up to have an intake pipe with the MAF sensor built in so there only needs to be one silicone joiner at each end and reduce the number of joins and clamps and air flow disturbances.

With smooth air flow in mind and to help accurate MAF sensor results during operation, I have got hold of some honeycomb air flow straightener. This design is much less restrictive to air flow than the factory mesh screens and importantly it actually works, straightening flow for laminar flow over the MAF.

Ste up and measuring the MAF location and pipe layout. Fits well around the battery and lines up well with the turbo inlet bend so it will now step down from 4" into the airbox, 3.5" 75 degree bend out of the airbox step down to 3" MAF sensor pipe and 3" all the way to the last bend into the turbo down to 2.5". This should greatly increase the overall potential flow but more importantly the volume of air after the filter and available to the turbo.

The larger air box and filter should help slow down air flow through the filter and improve filtration efficiency as well as reduce flow restriction. It’s not trying to be a race car but efficiency and effective filtration can’t hurt when it’s out in the dust and heat.

Yes well, I thought the lid was thick enough and it is thicker than the rest of the pot, but it is still only 0.7 mm while the pipe bend wall thickness is 1.6. The welder said he can do it, but because he is more set up to do 1.6 mm stainless exhaust work, he needs other tips and gas shield etc for thinner stuff and unless he has a piece to test on it might just blow a hole in it when he first starts or if there are any gaps to fill in my cut-out it will be messy.

I will have the flange welded to the bend so it on the inside of the lid, then just rivet the one flange to the inside of the lid. hypoxic ischemic brain injury recovery The second was just a spare as it was the same price for laser cutting one or two. Might have the second one on the outside and rivet or small bolts through both but have not decided on that yet.

The inlet to the air box is also going to be riveted and glued with Sika or silicone sealer. I will cut a hole in the box side and shape it out to meet the inlet funnel shape for a fairly wide contact join area so it should be quite strong enough.
