My 87 GN is hot... I have done "all the cooling mods" and still running hot. I'm wondering if it's the high/low speed relay situation?
I have a moderately built engine, 375hp at the wheels, large front mount IC. I run about 210 degrees here in Tampa, FL w/ the A/C on. I've put in the 160* thermostat, fresh coolant and flushed the whole system, bled out all the air, has a big Champion aluminum radiator and the GN performance dual fans. The fans helped quite a bit b/c it was running in the 230-240 range!!! I know the temp sender is accurate b/c I can watch the temp rise at start then drop to 160 when stat opens before it rises again.
I have the Fast XFI 2.0 and fan comes on at 160. What I notice is that it doesn't "feel" like what I'd expect for 3100+ CFM. My mustang has a smaller Black Magic fan that feels like a hurricane when it engages. Makes me wonder if the FAST is only engaging the "low speed" relay rr is this just where these cars live temp wise in hot climates?
