normal EGT's with #8 plate

[Deezel4x4]

Recently I installed a #8 plate and took the truck out on the road. Irecorded boost psi and egt at various speeds . I was just wondering if theses were normal?These are empty highway speeds.

speed boost EGT

75mph 8psi 800

70mph 6psi 750

60mph 2psi 650

also when I mash the fuel hard and accelerate from 60mph to top speed the egt will climb but never over 1200 degrees,It will drop back down pretty quick when I get off the juice. also when I shut down how cool should the egt temp be?

I would say that the numbers you have posted seem ok. With egt's, a lot of things can change your numbers. Head/tail winds, slopes, basically everything that affects the speed of your engine. Overall, I wouldn't worry too much about the numbers.

Sounds like you are right where I was a couple of years ago w/ the 230/605 plate. That's right about where I was running EGT and boost with the #12 (manual trans) plate.



Isn't the power great!!!!!

You should be able to squeeze about 31 lbs. of boost out of it with that setup, pedal to the metal.

well with the foot through the floor all I have been able to get is 27 psi ,that is accelerating as hard as she will go from 60-top speed

do you guys think I should turn up the boost some to achieve 30 psi?I mean if it will help I will do it. Iguess that is what the allen screw is on the side of the elbow I installed. Should I call TST?

Also how much do I adjust the AFC starwheel?I have toyed with it a little and it seems that with the smoke comes a little more response it take off. Please anyone tell me how to get the most outta this #8 plate.
