esp-6 5 Posted November 21, 2018 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 1 CHESTNUTXE reacted to this Share this post Link to post Share on other sites
slydog 7,873 Posted November 21, 2018 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. 1 gerg reacted to this Share this post Link to post Share on other sites
dex 2,066 Posted November 21, 2018 First up ,, what radiator are you using ,, clutch fan or electric,, thermostat ,, oil cooler ,, timing ,, intercooler,, exhaust size ,, the possibilities go on 1 gerg reacted to this Share this post Link to post Share on other sites
gerg 10,875 Posted November 21, 2018 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.

LJDB 103 Posted November 22, 2018 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.
