    Default proper EGT range?

    What is the proper EGT temp range for a turbo'd zetec.

    I have just had a custom turbo setup installed on my I4 Cougar and one of the gauges my dad installed was an EGT gauge.

    I've read a lot of different stuff on the web on what EGT temps should be on various vehicles but nothing like our cars.

    I figure our engines are similar enough that I can ask you Foci guys with turbos, what your temp ranges are.

    Appreciate the info.

    I know some turbo eclipses that run 850 deg Celsius, I would like to know this too though.

    You have tell the turbo guru's in here where on the exhaust the egt probe is located. If it's in the exhaust manifold itself..it will be much hotter than after the turbo and on the downpipe.

    My EGT probe is located in the runner on my exhaust manifold before the turbo.

    It's about 1-1 1/2 inches from the exhaust port.

    My idle temps are usually around 700 to 800 F.

    Crusing at 70 on the highway it's around 1100.

    Flooring it and running 6 psi I've seen the temps go as high as 1500 for a sec before I let off the gas.

    I have a 2000 I4 Cougar. My turbo is an IHI RHB5, mounted on a custom log style exhaust manifold. Fuel delivery is stock. No cat with a 2.25" exhaust with flowmaster and quad monza tips.

    And that's all within safe operating temps for an I4. When you start seeing temps like 1600 at the manifold, then you have a heat dissipation problem(from what I've read). Also, you might want to find out which cylinder runs the hottest and monitor that exhaust port(depending on what type of manifold you have).
