I just insalled my pyro and will be pulling some long hills with a trailer soon. What is a safe max temp with the sensor pre turbo. What temp should I be backing off the trottle on the hills ( hope I dont need to back off)
I don't understand how you guys get them that hot. I can't get mine over about 900* That is with a car trailor and fullsize pickup on it with my foot on the floor. I realize that my sender is just behind the turbo but still. That only figures to about 1100* pre turbo.
With the EZ set on 4 or 5 my temps always stayed at 900-1000 degrees if I drove the speed limit and accelerated slowly. It only got higher than that if I had to start off from a stop on a long hill or if I decided to pass someone while towing. My trailer loaded weighs in at 10-12,000lb.
Well I am glad I installed the pryo. Whule pulling aprox 8000lb up 8% grade the temp climbed rapidly. aon the return trip I removed the superchips programing and pulled as well up the hills with a safe temp. I guess the Lightning injectors sent inmore fuel than stock and sent the temp up.
What is the solution? I guess go to 4" exhaust.
I noticed that my EGT temps run hotter at higher altitude, than at lower altitude if that matters?
Also, I have two EGT probes, one is on the top of the exhaust manifold right where the #3 exhaust turns down to the Turbo, and it reads about 50 degrees hotter than the probe mounted in the exhaust manifold right above the turbo, but monitoring the back cylinders.
egt`s will be higher at high altitudes,your truck is running richer there being as the air is thinner....451 mopar,,are you still running a stock clutch with the attitude?and how hot are you getting?thanks for replies................bama
My EGTs normally are pretty good unless I am towing.
My trailer is about #9,000+ and pulling long grades I have to back off a bit to keep the EGTs down around 1250.
When I poped the intercooler, and my boost was leaking, my EGTs were crazy! Half throttle (towing) and the EGTs would be 1400! I think the more air you can get into the engine helps lower the EGT Temps?
I have the Auto trans, all stock for now, but I plan to upgrade it.
