I recently added a programmer, and am unsure of what temp to set my alerts on my pyro. The sensor is mounted on the down pipe about 2 inches from the turbo.
Powestroke 7.3, Pyro temps.
- Thread starter strucky
- Start date
anything over 1200-1250 things are going the melt
that is too hot for post turbo...i would set it for 1000 at the highest.
Be careful, read above. The consequenses are $$$$$$.
ive seen a twin turbo set up that was glowing bright red and the pyro was at 1600 my jaw hit the floor. the highest ive ever seen a pyro was about 1275 and the turbo friction welded its self together
For the most part, the turbo can handle the higher temps, its your pistons that start melting if you hold it past 1250* for any length of time. I've hit 1500*F on my truck but it was for all of a half a second. Just remember to let it idle and cool down to around 350*F before you shut it off, unless you like buying turbos.
Is my picture a good ex. of what you are talking about. This was out of John Deere 6cylinder.
aluminum melts @ 1400. 1250 is no problem with a pre-turbo reading.ill hit 1600 on a hard launch but its only there for maybe 10 seconds then the primary turbo lights.
and like luke said, let the turbo cool down before shutting the truck off...turbo timers are priceless imo. matt

Actually Aluminum's melting point is 1220*F, regardless. Playing in the thermonuclear range isn't safe kids
.one of the things i always do on my modified diesels, is to run the egt before i put the mods on.....i do a couple of good uphill races with my foot in it to see where stock fueling temps are....also hook up the biggest trailer i have and pull it up a decent hill where i'm in it for a couple of minutes (especially downshifted and revved up good)......then i may exceed that temp slightly for a drag race where i'm not in it that long, but for pulling a load, i use that temp as my max
you use the stock fueling for your max egt? well if you get a good set of injectors you can go way over that. my buddy in libby has a 94 3500 silverado with a 6.5 and some how pulls 30lbs of boost out of a stock turbo ( hes tried about 6 different boost gauges and it still says 30 when hes pullin about 6k+lbs of a load) and he has to work to get his pyro up over 950 with 40hp injectors and i think a heath chip of some sort.
so its extremely hard to stay within stock egt range and " mod " a diesel by adding more fuel and boost you have to get lucky or spend a hefty wad of money on low comp pistons

Water/meth injection is pretty hand as well, along with upgrading the stock turbo. I know the reason I can't go WOT with my 04 Dodge with the predator on extreme for more than 10 seconds is that my stock turbo is just too small for the amount of fuel I'm throwing at it. But with different turbos comes more boost which means a possible popped head gasket which means more money needed for head studs and o-rings haha. Its a slippery slope, bombing a diesel
Mounting it on the downpipe is not a very good spot. Your temps are going to need to be lower.
Pyro should be mounted on the turbo or exhaust manifold, it really should be pre-turbo not post.
Also temps will change from turbo to turbo. I have a VW TDI and <1400 is acceptable.

i have my egt in the same place, which is where superchip and autometer say to put them, all the cats , cummins etc have them there also. i have a 99 stroke with a superchip programmer ,and run 900 all the time and have pulled 1100 a couple times but the wastegate opens and it wont go any higher but i cant lug it i have an auto tranny
I'd put it in the manifold, that's where mine is. I can spike it past 1250 on a long pull unloaded in the "extreme" tune on my Evo2 programmer. I run the race tune and rarely see over 1100 unless I'm towing into a headwind or trying to fog someone out with the trailer on
I don't know about superchip but Autometer does not say to mount them on the downpipe. You will not get a good reading. It will be lower. You are measuring EXHAUST temperatures, so the closest you can get it to the exhaust (exhaust manifold) is where you want it. That is where it is the hottest.
I have a tech article bookmarked somewhere that shows the difference in different mounting positions. I'll try to find it.
Ditto. Put it pre-turbo, in the exhaust manifold. I try to keep mine under 1200, these motors are way too spendy.

Wonder if mine glows when I push it up to 1800*???? LOL I should pull the hood off just to see!
My lil stock turbo is screamin for mercy and the bigger one is waitin for me to bolt 'er up... It's not a ford though.... But I agree with eveyone else, put that pyro in the manifold!
I have my Outlook set to defuel at 1200 deg (pre-turbo)... But when i lend it out that goes down to 1000 lol, mainly to milk the last bits of life out of my stock clutch.
When I first got the Outlook motitor, I beat the chit out of the truck for a while on the stock tune to see what my peak EGT was, then I set the defuel 200 degrees higher than that.
Anything above 1300 is considered to be in the danger zone on a 6.0L, I can easily get mine close to 1400 unloaded on the race tune... Gauges are a MUST.

I had a superchip in my 01 and later switched to a diablo flip.
Pyro was mounted pre turbo, and I could easily hit 1250* with the superchip. Added a catback exhaust which widened my ID, and gave me a straight muffler and this helped quite a bit.
Post turbo EGT should be in the 900* range, and I'd be catious when it hits 1000*. The straight mufflers arent that expensive, and will cool you down. The Donaldson BHAF air filter from Napa are huge and cheap. I think 1 rubber sewer pipe connector from home depot, and you have a nice open air intake which will also help cool your EGT.
