I called the insurance company this morning to reinstate my road coverage:cheers: and this afternoon took it out for a run.
I think, I say I think, I freed some HP with the electric Spal fans. One thing is for certain, when I let up on the gas to coast to a light, it takes longer to idle down than with the clutch fan dragging on it.
And now with the air cleaner grounded I can hear a decent radio too
Big concern is the coordination between the fans sensor and the T-Stat. I spent a lot of time experimenting.
I'd like to find a way to shut my Spal fans off after 3 minutes, and start again when the temperature is up. Right now the fans sensor and the t-stat are fighting each other on the low side.
I have a 185-200 sensor and a 180 t-stat. Both are new, replacing the first set which was 175-195 sensor and another 180 stat. The problem lies in the operating tolerances which are +/- 10 degrees in each, causing the fans to run continuously after the first climb to 200 and cool down to 180/185.
I know the fans shut off correctly,because I installed a 160 T-stat to see what happens. Then at cruise speeds the car runs at 160 which is too cool, and in town they shut off at about 180/185 from the 200 start like the sensor is set up.
I also drilled four holes in a 180 and that performed much like the 160. I now have a 180 with one hole drilled that didn't make much difference from a non drilled 180 t-stat.
Is there a timer I could wire in?
