Air Intake Temperature Gauge?

I asked in a local performance parts shop the other day and the guy said he didn't know of any available.

I am thinking it would be cool to see the intake manifold air temperature.

Can I just get a temp gauge and a thermocouple?

I am bit new to gauge stuff, having just got a boost gauge and installed that (took me all day :) ).

I have an intake temp sensor. It's hooked up to the microtech and i see it on the hand controller. However you could just get any temperature gauge and hook up the sensor to it. Mine is just a Holden Commodore factory temp sensor i picked up for cheap.

Where is the thermocouple mounted?

I'd like to put it in the intake manifold area, but I had a look and there doesn't seem to be a viable place on the stock RB25 plenum. Was thinking of maybe poking a hole in the hose between the plenum and air inlet pipe and epoxy the thermocouple in there. It's a bit ghetto though and God forbid it gets sucked into the intake.

On the link posted they tapped a thread in a plate and mounted the thermocouple in a gland, but there is no plate like that on the stock plenum?

I'm interested to see heat soak so just a temp sensor near the POD isn't what I want.

Ahh fair enough. Mine is inside the intake pipe just after the filter inside of the airbox.

Saw quite a bit of a difference in temps pre and post airbox install. Gonna route a cold air pipe from the front bar into the box aswell and see what that does.

I had a thought along these lines a few days ago actually.

I wanted to do this for some time, but I don't want to modify the crossover pipe with a fitting... which is probably the best place to monitor the temps from.

What I *might* try, is to stick the thermocouple probe into the short bit of rubber pipe I have where a boost line was removed when I installed a manual boost controller. Hopefully i'll be able to clamp the hose onto the thermocouple rod without any leaks, and the probe is long enough to have the tip in the airstream.

I'll keep you posted actually... Thursday or Friday i'll have a go at it. (after I replace my dead tacho) =-]

I found a basic temperature gauge at supercheap a while back. Bought it but never ended up putting it in.

Run off a small battery, had an LCD display. Had 2 inputs which meant if you put a wire on one side of an intercooler and the other on the other side of an intercooler (example only) you could see what temperature it is on both sides to find out the difference.

Funny thing is I only found it in my box of spare "random" stuff this weekend.

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.

      BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
