What are your EGT's?

[Shep1824]

What are you guys seeing for EGT's? I put the gauges and SCT on my truck and I get to 1200 by the time I reach 60 mph if I am getting into it. Is it normal to get that high that quickly?

What are you guys seeing when you are getting on it hard? I know 1200 is to be expected with a tuner but it seems like they get there too quick.

Seems about right to me. I get up to 1300 under 80mph.

That sounds fairly normal. It will continue to climb but at a much slower rate beyond 60-70 mph. You should be somewhere in the 1400 range by the time you hit 100 but it shouldn't climb any more from there since the intercooler really starts to help the EGT at high speeds.

Wow, 1400 seems really high, is there any potential for turbo and engine problems running that high?

For a short few second burst 1450 won't hurt anything. Running at those temps for a prolonged period will eventually bring all the parts up to a high enough temperature to cause problems. As a general rule of thumb you want to stay below 1200 -1250 for extended periods like heavy towing.

negative... the EGT concern is mainly for the pistons since they're an aluminum alloy and after heat soak of 1350+ I believe is when they begin to deform. You're not going to get them heat soaked in 10, 15, or 20 seconds while sled pulling, dyno'ing, or racing in the 1/4 mile with just a tune.

I can cruise at 100 mph and keep my egt's around 7-800...

Always a potential or I could be wrong. That's why we have the guages. It'll be ok though you just can't do it for very long. Hammering it to 100mph in our trucks is fast enough on the streets anyway.

What is the best way to reduce the EGT's? I know that water/methanol injection can lower them significantly but I don;t have the cash for that right now? Are there any cheaper ways to lower them?

Your right foot!


If you don't stay over 1200 degree's for an extended period of time you're fine.

These trucks will chug right along happily at or below that temperature!

Make sure you at least have a clean air filter. The zoodad mod can help funnel in some cooler air to help out as well.
