Whats a pyrometer??/
Ok whats a pyrometer good for and why would u need to know what the exhaust temp is?? I jus wanna know what its suppose to do and what if any benefits there are to knowing the exhaust temp. thanks

exhausty temp, tells you if your running lean or rich... You dont need a pyrometer an Air/fuel ratio gauge will work for you...
|
a pyromete is used to measure temperatures of things.... like tires basically is measures temperatures of solid objects that you can't stick a thermometer in... exhaust you can stick a themometer in...but might be more accurate with a pyrometer
|
my dad brought home this heat sensing camera thing from work... like you take a picture of something and it'll show the temperature variations within the part... one thing i thought was cool was taking a picture of my front wheel when it was hot... cause the rotor would be really bright (hot) and the wheel itself would be a blend of hot in the middle and gradually cooler towards the rubber

Mostly used for turbo cars

thanks rbjeepthing thats what i was looking for, as i have no turbo i guess i have no use for that.

its a good tool for all sorts of things, i use mine a lot of a/c diagnosis and finding dead cylinders.
|
the heat cameras rule though

IMO, anytime you change anything... fuel mixture, spark, compression... or otherwise alter the volumetric efficiency of the engine, it would be wise to have an EGT gauge. Unfortunately, the EGT gauge is really only good with a dyno and a wideband, since every engine will be unique. |
what else does exhaust temp tell us? if its cool its rich, if its too warm its lean correct?
|
btw when i said "you" i ment 1sykhatch, cuz he doesnt have a highly modifyed engine...
I always thought a pyrometer was a more accurate/ advanced version of a A/F meter... |
since someone else wrote about it, I won't waste the effort... instead, here is a good link that explains it very well.

good read tks :thumbup:
interesting tidbit of information "Many people think that the leaner you go, the higher the EGT gets. This is also incorrect. Peak EGT occurs at stoichiometry- about 15 to 1 for our purposes. If you go richer than 15 to 1, EGT will drop and if you go leaner than 15 to 1 EGT will ALSO drop. It is VERY important to know which side of peak EGT you are on before making adjustments." http://www.sdsefi.com/techegt.htm |
:wink: now you're edukateed.
|
nice read there Bruno....
and thats why you use a wide band and a egt...different information and more information is better |
werd... I have a Greddy 60mm PHW EGT gauge, and I still plan on getting a wideband down the line.
