Quadzilla Temps

[jlwelding]

Just curious if these temps are normal on a 80 degree day.
Fuel Temp 103
Coolant 194
Eng. Oil 175
Air Intake 122
Thanks

So... 122*F - 40 = 82*F outside temp roughly. Typically the intake and fuel temp will match on a long run. IAT is typically +40*F higher than outside air. You'll find that no cold air intake will change this being the intercooler does all the work. Turbo will create heat when compressing air. 

 

Engine oil temp seems pretty good. Just a bit high meaning either the vehicle is heavy or being worked hard. Possibly timing is set up wrong. The lower the engine oil temp the better. I typically float 158*F to 165*F.

 

The coolant is spot on for temperature. Just remember Cummins ECM CANBus can't show temps over 204*F and it will flip over to -40*F.

 

Big questions... What is your cruising RPM's at 65 MPH? What is EGT's at 65 MPH? What is your boost at 65 MPH? What is your timing at 65 MPH?

 

Clues to gaining the best... Stock HX35W and +150 HP injectors...

 

66 MPH is 2,000 RPM

Boost at 65 MPH is 2 PSI

EGTs at 65 MPH is 550 to 600*F

Timing at cruise state is 23 to 25 degrees at 65 MPH.

 

Going higher to 80 MPH.

80 MPH is 2,450 RPM

Boost at 80 MPH is 5 PSI

EGT's at 80 MPH is 600*F to 700*F

Timing at cruise state is 27 degrees at 80 MPH.

 

Make you think... On working with me to get a solid tune...
