Pyro temp

[jtomasik]

It's post turbo, just at the bend of the exhaust elbow coming out of the turbo.

It appears that the truck I bought has the Banks Stinger-Plus system, which includes the entire exhaust system that reduces back pressure, as well as the turbo mods and waste gate system improvements. I think they have a lot to do with the low temps...not to mention that the pyro sensor is downstream (about 2") of the turbo housing itself.

I'm thinking about adding the Banks intercooler, since mine's stock. I want to find out if it's worth the cash.

Just remember you need to add to your readings when your taking into account these guys that are saying they back out at 1200 are running them pre turbo.....so that would be more like 8-900 on your gauge....

As far a intercoolers go, i personally think for the price to power ratio, its much more cost effective to go with a 6.0 intercooler in your 7.3......Talk to Gcop, Tony put one in his Ex....also Superstroke(bill) put one in his superduty.....

Ok, so when I get my pyrometer...where should I locate the probe for the most accurate and effective reading? I'm just noticing that the question "pre or post turbo?" keeps floating around. Thanks!

[mschn99]

for the simplest install and most accurate reading, i would go on the drivers side exhaust manifold. drill and tap the hole about 1.5 to two inches in front of where the manifold ends and the Y pipe bolts up.....it is an easy place to drill on the truck as long as you are VERY carefull with metal shavings. Get a small container of greace or vasoline.....tip the bit in it and drill your hole. Then after a couple seconds, clean the bit and re apply the grease till the hole is drilled. Then do the same with the tap. I would clean the tapp back off about every half turn. Get a small magnet up in there periodically as well to catch as much as possible and you should be fine......just take your time and dont rush it.

Marc, thanks a bunch for the info! I'll keep the 800-900 temp in mind.

I've been bugging gcop for those door lock actuators...I think I'll let him alone for awhile so I don't work him too hard.

Ford engineers actually stated 1250 pre turbo sustained is the number i was told and 1300 as your red line remember its your pistons your trying to protect not the turbo thats why you should run pre turbo.

I've read that it's not just the pistons but the turbo can also suffer from high EGT's. As for drilling and tapping it's cake on the cummins, but not something I would want to tackle on a v8 engine. I'll let a pro do it

its actually pretty easy on a PSD smoke...

Is it really? I just remember seeing how tightly packed everything is in the v8 configurated engines vs the cummins. I wish I would have put gauges in my stroker when I had it. I always wanted to but always had to spend money on something else.

yeah Smoke its not bad at all took me about 20 mins to drill and tap. I did it just like Marc explained that simple. I can tell you this I had my pyro post turbo 1st then switched it to pre turbo after hearing a dozen or more stories of cracked and melted pistons. Its amazing how responsive it is now its moves like a tach does where as before it was very slow and I never saw over 800 degrees post turbo pulling now I can hit 1100 up a hill pulling pretty easy but is pretty easy to control with the throttle just back off till its stays put. I would be VERY conservative with egt #'s if you run it post turbo. Thats my experience. Later Tim
