EGT's

yellow 07 sky · 07-11-2008, 02:43 AM

Just wondering if anyone on here with a boosted 2.4, or 2.0 for that matter has an EGT gauge, or has measured their EGT's. Perhaps Ecoboost can chime in here. Talking with the subaru guys they all seem to get up to an average high of 1200 f. That's spirited driving, with a hard hill. Seems high for my 2.4.... And I've seen temps on the highway, climbing a hill, around 1400..... Now I assume when I get rid of my cat that this should help... Right?

1400 seams too high. I think engine melt down starts around 1500 or 1600

yeah you should probably go cat less as soon as possible. too much restriction will raise egts.

1400 is not high, i've been at high as 1700 in my other car and nothing happened. I wouldnt want to go past 1600 just to keep it safe.

Yeah, I thought 1400 seemed high, and that's typically only climbing a long hill... The meth injection seems to really help, and the temps drop fast when you get off the throttle. But I figure my temps will read a little more accurate when the cat is gone.....

1400 is fine, anything north of 1600 you're gonna want to let off the throttle

In the 2.4 cat protect doesn't even kick in until 1688 deg F.

However EGTs tend to be different for every engine and not really a good indicator of engine health. EGT's can drop with both an increase and decrease in AFR along with cam position too.
If you really care about what's going on get a WB02 and forget about EGTs

A wideband 02 is a good idea but completely ignoring EGT's is not. Hypereutectic pistons melt over 1600* I wouldn't want to just assume everything is fine because my afr is good and then scatter engine parts everywhere.
