anyone set up a temp gauge for the trans and or diff?
just curious what temps you see? thinking I might do a cooler down the road but not until I know I need one with a temp gauge.
|
I want to know where people are installing trans temp sensors. I am thinking of drilling out the drain plug and tapping it for a temp sensor.
|
You might ask Hustler, he seems to really like those temp strips. I know Savington has also posted in the past about trans and diff temps.

temp strips? like the ones Alcon makes for brakes?
|
I got 2 Aim temp sensors just waiting to be installed. Will report back after some hot summer track days.

baller. get em in

I have a spare diff drain plug drilled and tapped for 1/8 npt for ages and never got around installing it and hooking it up to my gauge. Someone come up with an idea to feed 2 temp signals to one gauge and make them switchable.

why not just buy a duel gauge i think they cost 30%-50% more. who wants one more thing to deal with, plus how will you know which display is which source. you could add lights, not a big deal but I cant send the signal thorough the light so you need a relay, seems like more effort then it is worth when you can get a duel gauge or even one of those fancy deals, where you can display like 10 things on one gauge if you want.

Um, is there any reason a SPDT toggle switch would not work?

starting at 89 dollars depending on color, plus 36 dollars for two temp senders. 125 for a dual gauge is pretty good I think, compared to roughly 50-70 per gauge for autometer: http://www.summitracing.com/search/B...c&autoview=SKU Disclaimer: The vei gauge I posted is for oil temp/water temp. I assume you could use two oil temp senders to make it work for diff+trans, but I'm not positive. |

I have the VEI oil/water temp gauge. I am planning on moving the water temp sensor to my trans so it really reads oil and trans temp. I am just not sure if there is a better place to install the sensor in the trans then the oil drain bolt.

I think the drain plug is fine for a temp reading however it is nearly a low point on the car so I would be concerned about hitting it if you go off. I have not seen the plug out of the car trans but perhaps a relief cut would get the sensor out of harms way. if the pug is thick enough that would be a easy solution

Drill and tap the case. It is good enough for engine oil pans...

310? that way hot? the fluid is breaking down right? why not run a cooler? see the end of my noob post

red line said it does not really break down till around 400f but they clearly state the viscosity between 200 and 300is about 1/4, so its like a 3x lighter weight oil at 300 versus 200f.
@ 195 viscosity is 19.5 ( est recommended high temp) @ 300 viscosity is 6.5 ( this is well into the range you should have a trans cooler) @ 330 viscosity is 5.5 the 300 temp was based on husler temp sticker, which I presume is a brake temp sticker which simply darkens as each temp benchmark is met. his temp and our temps may be higher |
Meh, I guess I should be running thicker oil in the trans than stock now since track and turbo are both being added to the list of things it must endure.
|
Will a clutch-type LSD benefit more from cooling than a torsen-type diff? I'd think a clutchpack has more internal friction, thus creating more heat than a torsen on a similar track and similar power.

Seems logical^
Could you re-plumb the power steering pump to run the fluid through the trans and a proper sized cooler? Additional fluid added aids in temps too. Maybe even some heat-sink hard lines. There was a Supra guy that machined his diff flange to drive a v-belt pump for his diff cooler. Yes it takes power away from the drive line but I don't see it being a noticeable amount. Plus the stock Miata diff flange has some meat to it. |
that is a good idea but it might be more effort then it is worth and i'm not sure about fluid comparability between the power steering pump and the trans. I'm not even sure what type of power steering fluid our cars take but it could be a issue. a small electric pump seems like the best choice. if you use the drain plug and the fill port I would be concerned about hitting the fitting over a speed bump or something. welding a fitting is a option but more work
