Would there be any benefit to putting an EGT sensor in the downpipe? Or does it need to be before the turbo?

 

Pretty sure it needs to be after the turbo....but not in the downpipe. I'm wanting to say it needs to be 18-24 inches away from the turbo.

 

actually it doesn't *really* matter, either will give you a temp reading, before the turbo will just be about 100 degrees hotter. The biggest thing you're after, or so Im learning, is to catch the changes made when tuning. Adjustments to timing can be picked up by the EGT more so than WB02...its a supplemntary tuning tool.

If you're buying one.......buy this one!!!

Not only gives you the temp reading, but the differential between each rotor!! Obsessive complusive?? Well at least thats what my psychiatrist says....

 

That EGT is sweet!

 

fawking right bro....I jumped on that ****!!

Good price too, you're hard pressed to find a single EGT (they NEVER read to 2000 either) with probe, wires, gauge for much less either.........love that pineapple

around $100... for dual EGTs , but only up to 1700 degrees.

one more 2000 degrees!

 

I'm running the Zeitronix wide band with the LCD display that will log EGT on the lap top software. Everything I read says to put the EGT before the turbo, but most of the info. I've found was on diesel sites.

 

Well it really doesn't matter. As said, the differential is what matters most.

I.e. - say the probe is pre-turbo and you have a WOT EGT of 1850....then you take out some timing and the EGT's climb....that will indicate that you've retarded too far and now the fuel is burning in the exhaust...

There is *apparently* many confusing quirks about EGT and I myself am fairly new to it, however I can say that either position will give you what you want, which is to know what happens to the EGT's when changing timing and fuel.

 

yeah, that makes sense. I guess I'll go with the downpipe then.
Thanks

 

Mine is in the DP, so far no problems and no complaint fromt he tuner.

 

i saw the ones pineapple was offering and they looked like airplane dual EGTs so i went looking around and found a number for ~$200 and less(with probes), not quite the great price everyone thought it was.

 

Not sure if it helps but on my 05 Duramax truck I put mine before the turbo. This way after a hard pull I can let the truck idle untill the EGT goes below 350 then I shut the truck off.
I know rotaries run hotter but I plan to use the dual one and put one before the turbo so I know how hot it is and then one in the down pipe.
Let us know what you do.

Anyone bought the dual one yet? how well does it work?

 

Where? do they go up to 2000 degrees?

I've bought the pineapple one and once its running and functional, you'll be sure Ill have my .02 on it......along with all the other junk Im installing

 

Post #7 in this thread.

$99 for dual EGT guage that goes up to 2000(even says its perfect for rotary engines right on the page lol) and each sensor is $49 for ~200 total. Not bad, I thought the pineapple one was a bargain. It would appear that the only difference between this guage and the pinapple one is the F and R markings and the guage faces look slightly different.

 

yea, not that the F and R would really matter much anyways since in my head the gauge would have to be horizontal to actually cause less confusion while thinking in regards to quick reference since in my head the top would be the front rotor and the bottom would be the rear.

 

How bout dead ceneter in manifold?

 

disregard.
