H&S MINIMAXX EGT Question(s)

[turbo kidd]

I just put my new MiniMaxx and S&B CAI on last weekend. Currently I’m running the “Hot” 120HP DPF on tune…..I have a 5” exhaust ready to put on, but it has been snowing this week. So I decided to wait until next weekend to delete. Running the Hot 120 DPF on tune my EGT’s hit 1450 when I was smashing my go pedal. I still have the default H&S defueling set-up (I’m not going to mess with it until I delete).

So, here are my questions:

1.) I’m going to run the “Hot” 250HP Tune when I delete….Will my EGT’s come down when I put my 5” exhaust on?

2.) What EGT’s should I be seeing and where is the danger zone? 1450 seemed high to me and I was nowhere near full throttle yet? I know on my 2003 5.9, 1250 was when I would get concerned. Now I’m really scared that I tapped 1450 and I wasn’t even all the way in it.

Thanks,
Karl (Turbo Kidd)

I think what you need to do is research the temps that start to melt steel, aluminum, and anything else these motors are made of.. 1450* is pretty dang hot.. I personally wouldnt want to get over 1100* or so.

I agree with you....My Dodge was moddified way more than this 6.4L I have, and I never got above 1250. I realize they are two different animals, but 1450 seems way too high!?!

I have heard that the 6.4L is safe until 1500 to 1600, but I have no idea if that is true. I also am curious to know how much the 5" exhaust will help with my EGT's?

Thanks!

the 5" exhaust won't help much.

1450 is nothing for a few seconds

metals melt at various temperatures, but there are cooling systems involved. Only time you really need to pay attention to exhaust temp is during sustained high temps

Thanks for the reply...Can I ask you a couple of questions?

1.) How high do your EGT's go with the Hot setting?
2.) Where did you set your defuleing at?
3.) Where is the danger zone on these motors?

Thanks,

Before I did my delete I would see 1450-1575 deg when it went into regen. This was with no tune only a intake.

You guys are starting to make me feel better. I was looking at your signature....With the 300 Hot Dam tune what egt's are you hitting?

Thanks
