with my excursions on the Bonneville Salt Flats, with a Turbo 4G64 in the Mighty Max. I found at the 2 mile mark my coolant temp was reaching 231 Degrees F. Ended up blowing coolant into the engine compartment, not to mention filling the overflow tank.
Running flat out for 3 miles turning 7000 RPM with 20lbs of boost heats things up a bit.
Now I'm having a custom radiator built to handle the cooling job.
Attached is a single plane drawing of the existing Radiator with dimensions they are building the new one from.
I'll have the new one in about 10 days. pix to follow.
