Pyro and Boost gauge - what kind and where did you mount 'em

[RichD]

I miss Green1


He'd be in this thread like white on rice.

I prefer more signal, less noise.

We're sitting at the side of the road, midway up a big hill in Okanagan, doin the cool down thing... throttle set to 'bout 2K rpm spinning fluids and waiting for water temp to drop. Air Conditioners are off. Doot Dee doo... WTB upgraded rad with more cores.

EGT just dropped to 300's, turned off throttle knob. Water temp barely moved but moving air through it will help now.

Since we've already discussed intercoolers and exhausts.... Any ideas for cooling system upgrades? Is there a thread?

[crushers]

is yours mid mount or front mount? (i am not on top of Delicas)
clutch fan or fixed?
4 X 1/2" core worked well in the Playdo. you just need to find a shop that will spend the time. i "think" the rad core came from Kelona.

fixed fan works best
can your (if it is) clutch fan be taken apart into 2 pieces and can silicone be added like on the Toyotas?

all this is from what i know with Toyotas ... it MIGHT be of assistance over here or it might not.

is yours the 300 or the 400?

Related question: Can a too high boost damage the engine? I mean if you keep an eye on your pyro, can you set your boost as high as you want (even if you can not get more power)?
Background: If I block the pressure release valve and I what the pyro, will it damage anything?

[crushers]

heat and boost are 2 completely different issues.
a pyro transmits the temp of the exhaust gasses
boost gauge transmits the pressure being exerted into the cyl.

max recommended boost without a intercooler is 14 psi before the heat of the charge of air causes the charge to actually negate the advantage. plus the hotter the air into the cyl, the higher the temp coming out.

next is the pressure being exerted on the bearings, con rods, head gasket, head bolts, piston rings, wrist pins. if the pressure gets to be too high then you have $$$$$ dead engine.

the Delica engines are excellent engines but unless you have a huge budget i recommend you don't go past 14 psi ... but then what do i know?

So... the Glowshift pyrometer I bought was crap. It died in a month. I could probably get a replacement for free, but I disliked it so much I wanted to change anyway. The main problem was that the temperature display was way too small, and it reflected so much light that I had to shade it with my hand to read the temp. It was a distraction.

So I ordered this: http://www.auberins.com/index.php?main_ ... ucts_id=19

What I like about it, besides the display being a nice size, is that it has logic and can record peaks (over last 100 hours) and supports an alarm. Also, the price. Its cheaper than most every one I've seen. And it supports my existing installed probe; just wire it up.

Will follow up with install photos soon...

So I picked up the new Auber Instruments unit today and roughed it in. Works with the existing thermocouple with no adjustments. Much more sensitive than the old gauge; I get temp readings right down to room temperature. The numeric display is about 1/2" tall which makes it easy to read, but the unit itself is quite small (that photo above is probably over double actual size). High quality terminals too. Really only good things to say all around.

I noticed it supports boost and other temp probes. Since it's so compact, I'm going to buy a couple more.

This is by far the best pyro available and its almost half the price of any of the others I've seen. Highly recommended.

Great alternative to the regular gauges! Let's see how it holds up over the time. I heard the same about the Autometer/Glowshift too, till a they died after a few month.

Hoping they are decent gauges, I bought a few a couple months back, hopefully get them hooked up some time this life...... did the pyro thing and got one more that I will toggle as an ammeter between two different points.

That's why I moved away from automotive/retail grade and got one designed for industrial applications.

Rich,
Does that gauge come with a probe or do you have to buy it separately? Can't really tell from their website?
Thanks

They sell them cheaper(usually) from their Ebay site.
They sell them with different options...... pyro probes(weld or NPT), other sensors, different colour LEDs(red, green, blue).....
Might actually be a good group buy to kill the shipping and may reduce price for a couple dozen..... I have mine already, so I am out!

Cheers

I picked up a probe with the heat shield material and 12 feet of wire from Mopac for $60

They sell the various probes. Use the navbar on the left.

For EGT you need a K type thermocouple with a working temperature up to 1600 F. Like this one. They have weld bungs and clamp on style too. Their probes are cheaper than retail.

They also have lower temp thermocouple for <300 F liquid or air applications (water, oil, ambient temperature applications).

Also they have boost sensors.

The instrument supports various sensors; its up to you which you want to use. It's not a multifunction unit; you would have to program it for different applications. But if you were using multiple temperature sensors of the same class, you could put them on a switch as I intend to do.

This is my instrument cluster plan:

Must have
[ Pyro ] - audible alarm at 1200 F
[ Water Temp / Engine Oil / Transmission Oil ] - on a switch

Bonus
[ Boost ]
[ Inside / Outside temp ] - on a switch

[RichD]

I have another order of my own in the works. I drive them over the border myself so if you want to group buy send me an email.

If you are in Vancouver, I have a small shop and can squeeze in 2 Delis at a time for pyro/gauge installs.

[ Boost ]

Can you use the existing thermostats?
Does that mean you can use one gauge with multiple sensors? That would be awesome.
