hey i was just wondering what kinda temps u guys with egt guages on your tubocharged rides are running .... i have the autometer egt and i stay mostly at 8 mark at idle and between 10 and 14 when im driving ... its also 90 degrees up here right now, but i was wondering what is to high of a temp and what is say normal for are cars thanks.... ps i know that these r not exact im just lookin to see where i stand and have something to go by



dont want to heat up and blowup.gif

 

I don't know, give me your gauge and probe and I'll find out. fing02.gif

Temps vary on different setups.

 

basically, there is no hard and fast rule with them. The temp is going to vary with how rich or lean your car gets as you drive. If I remember correctly, the temp will go down with a rich condition and raise when it is running lean,, don;t quote me though.

 

where do you have the probe? in the manifold? if so which cyl? in the downpipe? how far from the turbo housing?

 

i have a log style manifold the probe is in the center its not to far from the turbo housing about 6 to 8 inches... i know that there is all kinds of things that are gonna determine this temp... im mostly concerned with how hot is to hot ... im going soon to have it tuned so .... i have to drive the highway for about an hour to get to to the dyno it seems to be running smooth now but i havent really drove it that far yet it will probably be better on it than the stop n go traffic around here though

 

As said, different gauges from different companies will read different temperatures in different places.

Best thing to do is get it dyno tuned and see what your EGT temp is when your running where you want to be (12.5:1 A/F, etc.). If you start seeing the temp go way above that mark, you pull over and let the fans do their job.

 

Well just to give you an example.

I am using a log style manifold. I have autometer probe in the first exaust port runner. My air fuel ratio is 11:5:1. My egt temps when I am full throttle are around 1550. I would try to keep them around there. As 1650 and above will result in engine damage.

Ps @ idle I am around 9 partial throttle driving I am around 12.5-14

Hope this helps

 

thanks man exactaly what i need im around the same 8 at idle, normal driving 11 to 14 havent let it go above 14 yet thanks again

 

I have the Autometer EGT gauge in my Alpine log manifold close to the Cyl #1 runner. My temps max out at 1550F at full load, when just letting the car idle temps are about 800F.

 

if i remember right cast iron melts at 1200 if you are that hot something is wrong
now if it is alloyed with some other metal then it is higher.

i am worryed about them temps, you guys better check to make sure
