water and oil temp.
The temp here in Atl. Ga. is around 80. I have a fe 428 with a mild cam. When traviling im fine, but when stoped or really slow travel the temp. starts climbing. I have 2 push and one pull fans. Sitting in my driveway i varied the revs for about 15 - 20 minutes. The temp got up to 220 and the oil reached 200. I shut it off, came back out in 5 min. and it almost didnt start.
What kind of temps. are you getting ? Is this normal ? What can be done to get it lowered ? The temp. in summer here gets pretty hot and its only 80 here. THANKS OLBLUE |
My new aluminium motor was fine on the road, but got hot when subjected to stop and go traffic. I kept the puller fan and had a custom radiator shroud fabricated and installed. Then I dumped the ethylene glycol and replaced it with distilled water and Water Wetter. The overheating disappeared, although I do try and avoid heavy traffic when possible anyway. My beast is fortunate to live in a garage in a very temporate climate, so freezing isn't a worry. Life is good. ;) Rich

Bigger fan... www.flex-a-lite.com

Btw... The flexalite black magic 150 has a built in shrowd and is exactly the same size as a contemporary's radiator opening. With a few custom stainless brackets it bolts right up to the Contemporary fan support.

With 80 deg. temps, it should not reach 220. I have a 428 with a high lift solid cam & I'm running a 180 deg. thermostat, one puller fan...for now. Anyway, With 80-85 deg. weather, I never run over 205 deg. in city traffic. On the highway at night & around 60 deg.'s in air temp, I even have to turn off my fan or the water temps go down to apx. 170 or so. I plan on buying a automatic switch, sometime I forget to turn it back on. In the heat of the summer of around 95 deg. air temp & in traffic, it can get up to 210 deg's but,.... rarely. Questions, what deg. thermostat are you using, who's radiator, are you using antifreeze, what type of water pump ? Oh, I also use reverse osmosis or distilled water with "water wetter", good stuff.

Do you have an oil cooler as well? Preferrably a big one.
Make sure that the air has to go through the radiator (ie that the gaps around the radiator are closed up, and that the fan has a shroud. What kind of radiator do you use - one of the big aluminium ones? I have an aluminium radiator, large oil cooler, run standard 50:50 mix of glycol and water, have one electric push fan, an electric water pump - and I have problems getting my car warm enough! Actually - writing all of that - what is your water pump like - maybe not circulating enough? |
