Dual Egt Probes

Recommended Posts

So I recently acquired a Quad with V2. However I just finished installing an EGT probe for my Isspro gauge prior to getting the quad. I'd like to run pillar gauges since I have had them on the shelf. But also want the gauge to work with the quad. Can I install another probe either above the current one? Or install the second probe in the front half of the manifold?

^^^^^^ what he said. That's what I did.

The variation in temperatures shown between the gauges can be attributed to the calibration differences by the manufacturers as well as cylinder fueling/combustion efficiency.

The aft 3 are supposed to run hotter, which is why they are the preferred ones to monitor. 

 

I put my 2nd probe post-turbo and am glad I did. The info it gives me is much better than having 2 probes in the manifold. Post turbo is quite useful for cool down and lugging, both of which are masked by a pre-turbo probe.

What is the process for adding the probe? Drill and tap the manifold in the rear section? I assume the turbo would need to be removed to catch any metal shavings? Anybody have a suggestion for a gauge?

@Red Rambler Get the tap kit from DAP if you don't have access to those tools. Isspro guages. Install guides: http://www.dieselmanor.com/diy/CMS-G2gauges/CMS-gen2gaugeinstall.asp There are plenty, just search the forums.

Thanks @gipperkid I purchased my mechanical fuel gauge from diesel manor. I can get a 1/8 npt tap from oreillys. I may already have one, just need to check. I was doing some research on glow shift due to price point but quickly said no due to the negative reviews. Isspro is what I am after. I like how diesel manor says to use small drill bits and step up to a larger bit to keeps the shavings small.

When I tapped mine I had the turbo off and just stuck a rag in the manifold, drilled and tapped the hole then pulled the rag out. Cant believe anything small that may have been left behind would not just pass thru.

@AH64ID I like the idea of monitoring temps before and after. I just hate to take the turbo back off to drill the elbow. I could probable put a weld in bung on the down pipe.

Yea. I drilled and tapped mine with the turbo off. Stepped up drill bits to the final size. Use Plenty of WD40 when cutting the threads. Use anti-seize on the probe adapter threads.

Do you have pics of your post turbo probe setup?

@crf450ish I wish I did. No one around has a smarty I can borrow. And I'm definitely not paying the dealer. Need to buy a new pyro for the quad also.

Dude you can rent a smarty from DAP in Utah. By snail mail. They place a hold on your card for the cost of a smarty ($600) and once they get it back safe & sound thy refund you the $540. Yes, it costs $60 to rent. Oh well. It works and hey, you get to play with a smarty for a bit. Just don’t stack it with anything. At all!

I don’t think so. My Jacobs exhaust brake came drilled/tapped for a probe so I used that hole.

My Banks came that way on the elbow. Just never thought of putting one there. Live and learn.
