where would the ideal temp be to start driving the car? would it be safer to wait or is it ok to just start driving?

 

anyone have an idea?

 

I believe mine used to sit around 300* or so Celsius

 

thanks man

 

Are you guys running both an EGT gauge and a AF gauge?

My understanding is that EGT is a good secondary reading of how rich or lean the motor is running at WOT. 850-900C being ideal, 925-1000C too lean, and temps below 800C rich. I guess the question is what does EGT tell you when not operating at WOT?

I agree with this. I've run an EGT gauge for the last 3 years and never got around to getting a wideband. Seems like the EGT tells me jackshit if I don't know what the afr's are at.

 

Could be wrong but even if your air/fuel is right your timing can cause your motor to run hot. In this case egts are beneficial. But yes I run both egt and air fuel. But I would not buy an egt guage b4 buying a wideband.

But lets not tun this into a debate of whether an egt is worthless. Keep it on temps.

 

In regards to EGT showing your timing is wrong, your coolant temp will do the same thing if the timing is wrong
