He didn't mention the severe duties & I, honestly, forgot to ask.

 

teamrip is out of the thermocouples til late spring. I came across these however. 50 milisecond response time. anyone know anything about them?

'like the resonse time... not particularly worried about the statement that they should be removed after you tune due to longevity as they are all the same and many last years. i don't like the un-necessary length.

i think it would be great if anyone w a bit of time could do some additional searching for a shorter less marked up in price probe... it would be great if we could find the actual source (as in manufacturer) of the TeamRip thermocouple..

talked to Teamrip again today. They will most likely not carry them anymore. BUMMER!

 

These are the ones I purchased. Made in USA for those of us Union types. ;-)

^ Nice but they look expensive and they have a fairly slow response time.

 

^^ the response time on the sever duties is 250miliseconds and not the 500miliseconds that's posted on that page. I had several conversations with the owners/managers about their sensors. There are several versions of that website's products. The correct page is:

http://tscsensors.com/egt-probes--racing.html

The regular non-heavy duty are 200mili and the severe ones are 250. See post #121

 

a brief update. car is getting closer to being back on the street. a few pics.

 

Move those probes as far from the flang face as you can, whilst still keeping them pre turbo.

Having the probes that close will cause them to burn up quicker.

I know it's hard to do, but optimal placement of probes is 6 inches off flange face.

 

i followed coleman's advice - sorta. They're about 2 inches from the area where the manifold touches the manifold gasket. Or 1 inch from the outside of the flange.

 

I'm wondering if HC placed his probes that close due to manifold length restrictions.

Was that when he was running his true twin turbo setup?

Fuel/ Air is still combusting once it leaves the engine, the farther from the face, the more time the fuel has to burn (giving you a more finalized EGT measurement)

Hopefully Howard will chime in and shed some light.

And if I'm wrong, at least it will be publically (so we can all learn from it)

 

I've spoken with a tuner and he said sometimes things (i dont know what they are called) on the tip of the sensors can break or fall and can damage the turbo if sensors are installed pre turbo so he always recommends them installed after the turbo on the dump pipe but o course this means no seperate measurement for each rotor. Is having one egt connected to the dump pipe pointless in rotaries?

 

Thewird, do you know if the analog box from TSC can read 2 sensors?

I bought their kit (analog box with sever duty temp sensor), but only bought one sensor (putting it in the rear rotor exh pipe) but would consider an aditional sensor if the analog box can take it simultaniously and hook it up to my PFC Datalogit

 

"he always recommends them installed after the turbo"

which makes them close to worthless. the spread pre and post turbo significanlty changes so it is not constant.

secondly you really need to know the exact temp of the exhaust an inch and a half (+-) after the flange.

finally, i am not aware of EGT turbo damage. generally they just slowly melt away over the years and cease functioning. i have two 4 year old EGT sensors. one stopped working last year and the other still works.

the more probable way a turbo gets damaged is by having a piece of apex seal say hello from too much egt... which you could sidestep if you have and monitor a preturbo egt.

be extra cautious w this tuner.

good luck,

howard

 

Thanks Howard. I also have not heard any turbo damage due to egt sensor failure but since this guy tunes many cars I just wanted to ask in this forum to doublecheck. And since Howard Coleman says 2 sensors pre-turbo who am I to argue. Although it shouldn't make a difference this tuner was talking about 4 and 6cyl engines and has some experience with power fc but not rotary engines since there are only a handful in the country to begin with. Anyway sorry for the thread hijack.

 

ideal EGT for piston engine 1320 F

ideal for rotary at full boost around 1650 F. you don't want much more than 1700.
you also want around 1400 F from zero to one bar. work w the timing.

thanks for the replies HC! Good info.

 

When you are aiming for your goal EGTs, is there any consideration to how much port overlap your housings have? I would think guys with larger ports and more overlap would have more diluted EGT readings because of the intake flowing through the chamber and out through the exhaust ports. Now that I think about it, I think different turbo setups and how much boost you are running would also play a part in diluting EGTs since everyone's setup will flow differently during port overlap.

 

I've got a dual PLX setup I will be installing shortly. Hope to get it done in the next couple weekends. I'll follow up with some pictures and observations.

 

Hey Guys, Im planning on doing the dual egt setup with the haltech and wanted to know what you guys thought about these before I buy them:

Amplifier: http://www.exhaustgas.com/ProductDet...pID=&BasketID=


Thanks

 

no one?

 

They looked good to me. You want to keep the temp rating as high as you can get it while keeping the reaction time as low as you can.

I've got no experience with that company

 

WOW

Indian has found the source. if you read the 100+ page catalog you will know more about EGT hardware than most and it will be apparent that we have found our source.

this is a fabulous add to our thread.

thanks Indian

yeah there's a lot of stuff there. I really liked the dual channel setup that Indian posted for his converter. It's within my price range and looks like a efficient solution to getting the EGTs into a usable voltage.

 

your welcome guys.... gosh Im almost blushing. lol
