pyro

jinzuke · 11-10-07, 02:56 PM

If I have the turbo and manifold off wheres the best place to put the pyro prob. Is their a spot just under the exhust side of the turbo, their is a thread their.

cruiser_guy · 11-10-07, 08:28 PM

Where all cylinders come together, usually right before the turbo inlet. That's my opinion and that's where they are on my trucks.

HJ61TurboDiesel · 11-11-07, 02:43 AM

And what if your PYRO assembly should shred some pieces or you have a bad weld falling off? Bye bye turbo, bigtime.....

It is safest to put it downstream the turbo. Keep in mind that the temp could be as much as 200 deg C cooler here if you have an efficient turbo setup at max load.

Other than that it is a matter of choice.

No welds to fail. I drill and tap the manifold. The sensor is rated for something around 1500F. If it fails I'll be chatting with the pyro manufacturer. I'm NOT going to guess what the temperature might be where it's important, I want to KNOW!!

jinzuke · 11-11-07, 07:49 PM

2nd that We pay the big bucks for a gauge to work right. I don't think chip from drilling and tapping will be a problem cause I can just wash it out.

dieselDaryl · 11-11-07, 07:59 PM

I'm doing my pyro install this weekend in my HJ61.. I plan on putting it pre-turbo without aking the manifold off the engine. I'm just going to run the engine while drilling/tapping it (so the exhaust pushes out some/most/all of the metal pieces). I think Brad (The Dude) did that..It should be okay.. Anyone disagree?

BillyGHusk · 11-11-07, 08:48 PM

I need to install a pyro on my 3B as well. However, I am lucky(?)as I need to change the manifold gasket also. So, I plan on installing the pyro at the same time. I meant to post pictures when I asked this but oh well.....on the 3B I was going to put it where the manifold gathers(best word I could think of, leave me alone I'm no Edgar Allen Poe) up. I have never taped anything like a manifold any tips....need a drill press or get it straight enough by hand? Pyro brand/model suggestions?

Tim

dieselDaryl · 11-12-07, 12:50 AM

I drilled and tapped the manifold on my B engine at the point you refer to.. I did it while on the truck and picked the best possible place that was also easy to drill/tap. I did it by hand with a hand drill and am very ahppy with the results.. I used an Isspro EV gauge. I don't have the part number off hand but it's easy to find on their site. They can make any of their gauges up in 24V..

_Walker_ · 11-12-07, 03:56 AM

Im thinking of going with the X-monitor by BD diesel... anyone heard good/bad? Iv gotten tired of using analog gauges...
I was planning on taking the gauge apart, and flipping the display upside down, then mounting it to the bottom of the HVAC controls peering up...

This is where I placed my pyrometer. I went with Isspro pyrometer and boost gauge for my truck. I don't know how far to set the prob into the manafold.

Towpack · 11-15-07, 01:32 PM

Jinzuke
I fitted the same pyro/gauge combination and in the same position as you have.The depth you have the probe set looks ideal with the tip in the centre of the gas flow.

I drilled & tapped my manifold while fitted to the engine and it caused no problems.Used plenty of white grease to catch the swarf and drilled slow and steady,especially when the drill starts to break through.When the pyro was fitted I pulled off the inlet hose to the turbo and spun the turbine for a few seconds with my fingers to just flick any stray metal chippings through the housing before starting the engine.Probably not really neccesary but just gave me piece of mind!

Ditto .. pre turbo and calculate the probe in the middle of the gas flow ..

_Walker_ · 11-20-07, 11:26 AM

Well just ordered one, we shall see if it was worth the coin!

That's a really neat looking unit and saves space no doubt.Difficult to see how big the display is from the picture but personally a prefer the 'instant readability' of a standard gauge.Just a quick glance at a standard gauge and you can see right away where the needle is,wether it's in the normal or danger zones rather than having to actually 'read' the gauge...if that makes sense!

Dazza · 01-04-08, 03:43 PM

don't mean to hijack...

is a pyro necessary without a turbo??? not sure, seems like it is only for measuring heat for turbo.

BillyGHusk · 01-04-08, 04:16 PM

actually I think(with my limited but expanding knowledge base on diesels) a turbo will actually help keep EGT's down due to the increased volume of air moving through the engine.

now wait for it......

lets see how right or wrong I am...

A pyro is to get an indication of the combustion temp in the cylinder,not for measuring the turbo temp.That's why it's better to have the sensor upstream of the turbo as close to the cyl head as possible so you get a more accurate reading.The temp drop across the turbo itself can be considerable.Too high an EGT means melted pistons,not turbo damage.

Dazza · 01-05-08, 12:08 PM

thanks Phil

So in that case, it would be good to put a pyro on any diesel, not just turbodiesels, right?

i will be installing a 6.2L chevy diesel soon, how would you mount it on a v-8 non turbo diesel? maybe at the y pipe? would that be accurate enough, or do you need to get the manifold temp at both sides?

Towpack · 01-05-08, 04:17 PM

Pyros can be and are fitted to many non-turbo diesels.

As far as a V8 is concerned the Y pipe would be to far away from the heads to be much use.(I'm assuming here thet the Y pipe is where the down pipes from both headers join).

I guess,if you were a perfectionist you'd have 1 pyro sensor for each cyl bank and either a dual gauge or 2 seperates.

IMO if the injection system and the engine in general is in good condition then one,header mounted,pyro will be sufficient as the EGT from both heads will be near as damn it the same.

Why a non-turbo diesel?? In my book a turbo is as important to a diesel as fuel injection is to a gasser. The performance improvements FAR outweigh any negatives in my way of thinking. More power, better fuel economy (assuming you're kind to the skinny pedal), ect, etc.

I've heard the later 6.5's are better engines anyways.

Like others are saying, as close as possible to the head for the pyro probe.

Dazza · 01-05-08, 05:09 PM

Each motor has it's ups and downs, and the 6.5's have some issues that don't work for me, one is the electronic fuel injection.

What I like about the 6.2 is it's simplicity, being manually aspirated and mechanically injected. I will be using 12 volt glow plugs wired to a pushbutton on the dash running through a ford style solenoid to avoid the faulty auto 6v glow plug setup. I found a great price on a recently rebuilt 6.2 with all motor accesories I needed, which sealed the deal.

The 6.2, as I understand it, do not work as well with a turbo due to the higher compression. I do agree that most diesels will perform better with a turbo.

I will try to go with the one pyro probe right off the head. thanks guys, sorry to hijack

jinzuke · 01-06-08, 01:29 PM

Ok I have the pyro installed and the boost gauge installed. What temps are people getting with their 1hdt. My turbo spools fast hits 10psi quickley. The pryo hits 1200f just getting on to the hiway with the skinny peddel not to the floor. On the hiway @ 1950rpm the pryo is @ 920f. I have just done head work took a few thou off the head new timing belt new injecters and lapped the valves. I used a # 5 head gausket insted of a #3 to make up the interference difference. I have not done the timing yet. could this be why my pryo temps seem high.

Tapage · 01-06-08, 03:34 PM

I'm not really sruprised know your EGT high .. normal IMOP in a old ( never test a new one ) 1HD-T .. with some wear in the IP and injectors ..

TOYFN · 01-12-08, 07:03 PM

Jinzuke
I guess I should check the site more often. I wound up purchasing one. I finally completed the turbo recondition(what a difference that made) and installed a pyro. Lots of fun taking the manifold off. Thanks for the offer. I have the same cruiser as u do. 1-hdt etc.

Also now with the new turbo and the gauge I am finging the temp at 1950 is running around 750 f. I really have to tromp on it to hit 1200f. The truck reaches 130kmh much quicker now, with no trouble.

I think we met once at a VI cruiser meeting. I live in Brentwood
