keeping temps down with turbo

7 posts in this topic

As the title suggests, 

whats everyone doing to keep engine temps down with a turbo 250 crossflow setup? 

Mine gets to 220F at lights and usually sits around 200F when cruising

 Mine is blown but there was zero difference between NAT ASP and blown with engine oil and or coolant temp.

 

Id suggest using a iron head water pump pulley to slow the pump down to allow it to cool in the radiator longer or going to a electric water pump and controller.

 

My car never went over 85c coolant temp or 185f all last week on Drag Challenge even after 3-4hrs stints.

When you're not on boost, it shouldn't make a difference whether or not it has a turbo bolted to it as to any temperature issues. How did you achieve boost retard? If you just backed the timing off at the dizzy, it might be retarded to the point of cooking the motor.

Iv heat wrapped the dump pipe, turbo beanie and made a heat shield for the exhaust manifold from a b series heat shield. Iv also played with different thermostats and water pump pulleys to get it right. Im using a fixed fan with small water pump pulley. With the larger pulley, coolant temp fluctuates alot between driving and in traffic. 

If the turbo is water cooled the places the lines are tapped in may effect the system aswell.

wouldnt have a clue to be honest, was tuned by JPC - temps have slowly been getting worse and worse
