REFLECTOR: High speed ground cont.

[Chris Barber]

I have a two fans. A four inch for oil and an eight inch for the cooler. They move air but not certain how much difference they make.

I have another eight inch and two more four inches I can add but I am concerned they may restrict air flow through the heat exchangers in flight.

Thanks for sharing. It is reassuring.

I have a large fan on my radiator and a small fan on the nose oil cooler on my XL with the LS1. The fan on the oil is a 5" one from Jegs and works great. It brought down my oil temps significantly and kept the temps low so I could taxi as long as necessary with no concerns. After takeoff the temps lowered significantly for oil and coolant temps compared to taxiing and run-up. I was testing with OAT around 70F.
Looking forward to hearing about your first flight.

Just did another nose lift at about 70 kts. OAT is indicating 107 degrees on my engine monitor. Coolant temps were around 200 when I took active after a long taxi and waiting for a Cherokee to taxi in. Oil was lower.  Coolant went to about 210 when powered up at the numbers but started to drop slightly as I built  speed. About 205 as I left active and 215 as I got to hangar.

I don't think that is too bad considering the conditions, Really hot and humid.

I was also happy the temps started down as I gathered speed even though the run down the runway was only several seconds. I would hope the temps will continue down to preferred levels as I continue to increase speed. Impossible to know while on the ground.

I know, go fly and find out...  Uh, yeah, but with mid-day temps at 107 on the ramp I think I prefer an early morning and less wind and likely much less bumpy.
