Can anyone tell me the normal ex . temp for a 1993 rx 7 and what is the danger temperature for a rotary engine .

 

Dude search. There is alot of info.

In celsius

95 is good
105 is getting hot
110 is hot.
120 your engine is toast.

I like keeping my engine 85 - 95.

ex. temperature?

 

exhaust temp

maybe you should think a little before you decide to post a ******** comment.

He is asking a simple question and the search function blows on all forum sites unless you know the exact name of the thread.

To OP Im not sure what the safe temp is but im sure someone will chime in with an answer

 

https://www.rx7club.com/showthread.p...+exhaust+temps not exactly but it's in the right direction.

 

ex temperature not coolant temp. (try and search for an ex temp chart here, good luck)

 

Thank you for the chart and covering my back

Keep in mind that the temps are dictated by the probe location. i.e. you cannot compare temps if your probe is not located in the same area as what has been posted.

 

really depends on the probe location and what position the throttle is at.

I think most try to keep it less than 1800 at idle. (this is with the temp probe about 1/2 inch from the exhaust port)

 

You have got to be kidding me. How do you figure that? I told him to try the search and I gave him an answer to what I thought was the last part of his question. It would have been different if the OP stated that he searched already but that wasn't the case. The problem with simple questions is that they get asked alot. These questions have a tendency to clog forums. You're also incorrect about the search, the exact name of the thread is not needed. There is a pull down under the advanced search that is set to entire post by default.

I'm glad you found what you were looking for blue.

Also, I could have sworn the subject was ex temp when I checked last night. Weird.

 

my exhaust probes are 1in away from port .just cked e temp we are running at 1459 at cruise speed 70mpgh under boost at 10.5 lb 983 on the fat side byt safe.

 

^Celsius right?

 

1500 degrees celsius? His exhaust manifold would have melted before reaching that temperature.

 

farenheight

 

how is it you only get ~ 600Celsius at WOT ... ?that is extremely low .. especially at the exhaust port ...

 

I see around 1200 to 1300 cruising on the highway, and 1400 to 1500 Peak readings when redlining it at ~15 psi boost. Readings in F, probe in downpipe about 2 inches from the turbine housing. If your probe is in the exhaust manifold add around 150 to my numbers.

 

we run 950 under boost (running fat to save the motor) at 24 lbs boost . just added 75 shot to help it leave, making total hp to 644 wh. Motor was done by jpr imports tuned by pfs

 

what kind of timing are you guys ruining ... i am confused .. 600 Celsius on boost ...
how much water/meth ere you dumping in ?

 

950 degrees farenheight is under boost no methanol , race fuel only, 20 degrees timing 850 pri. 1600 sec inj
