FI gauge options
I tried putting this in the supercharger post, but the standard turbo vs. Super vs. Teamrx8 vs. The world drown me out.
When I ran turbo I used a EGT gauge which was very predictable and reliable with its warning of going lean. What I ask of the supercharger guys is do you recommend an air intake temp gauge post compressor instead to monitor the engine?
The reason I ask is with the turbo my main concern was going lean under boost, which would show up on the EGT. Whereas from what I see supercharger setups are more stuggleing with overheating. Any input would be helpful.

I would say EGT and AFR are still very important, as well as fuel pressure (very important). IAT post compressor is a good idea as well. But a good large cooler for your SC cooler is the best bet to avoid heatsoak.

1) AFR = if anything, you can see that it's the fuel delivery troubleshooting..either the pump, injectors, or other things..if you have AFR and fuel pressure, it's also good if you have money and space..lol..
2) water temp and oil temp = to find out the temp in summer and or hot temp, for both, oil and water
3)oil pressure = just making sure that there is always a pressure from oil..
i have 6 gauges, 3 tops and 3 ashtray...
top (boost, AFR and oil temp)
ashtray (oil pressure, EGT, and Water temp)
for example, when i had fuel pump filter and injectors, my AFr ran lean..so we had a little clue where to start if a troubleshooting is needed..
i hope you can decided from what i just explain..

not really steven although i appreciate the attempt. I have a wide band AFR, and EGT, and my boost gauge. I just want to know if I should replace the EGT with a IAT. AFR will tell me my engine has blown, and EGT or IAT will tell me when my engine is 'about' to blow. I just curious if those running superchargers can "see" better data with their IAT

I´m pretty sure that any gauge won´t save you when something goes wrong. EGT sensors are too slow and their real meaning is at full load and only when you realize that EGT´s aren´t about some absolute number. IAT gauge also won´t alter tune.
Gauges are cool, but watching them is last thing what you should do at high speed...
I just don´t see their meaning in age of data logging.
Personally, I would be scared to see post blower temps

I get it!!!! I KNOW WHAT THE GAUGES DO!!! I ran my setup for over 40000 miles with my turbo. Yes bad to look at gauges going fast: solution is my peak buzzer. Yes i know EGT is all relative, which is why it was logged under WOT in full boost to see what was safe and what was approaching too hot or lean. I use them to monitor my engine in dangerous situations, a good EGT gauge should warn you of going into a lean condition or dangerous overheating before an AFR will.

could one of the supercharger gurus answer this as opposed to random peoples personal opinions on data logging and the benefits of gauges?
Simple question: does a IAT gauge give more relevant data on dangerous overheating and detonation in a supercharged engine than an EGT?
