Thread: 327 What's your average water temp?

Tweet

your water shouldn't affect that, if u have str8 water that boils at 212* F, and then u add a 7# rad cap ( standard for most anything older ), for every 1 PSI of preassure, the boiling point raises by 3* F so that's 21* more so your looking at 233* F, which if you get to 230* F as is, your almost overheating, because when the coolant boils, that's what overheating is. ither change all hoses and go with a 10-13# cap or get a cooler thermostat. if you have a 180* stat, it will be fully open at 195*, a 160 will be open at 185*

Well I changed the fluids today and found that it made a "little" difference. Around town after a half an hour or so she runs about 210-220, on the freeway after about 10 minutes she was down to 175-180. This tells me not enough air is getting through, but I am not sure what i can do about it. I have an electric fan on my radiator, how much of a temp difference would I see if I add a shroud? Because I live in the DC area I need to be able to sit in a 30-45min traffic jam without overheating, any ideas?

Thanks in advance,

a shroud makes a big difference.... also depends on how many CFM/RPMs your electric fan puts out....

I would be curious what cfm the fan is pulling or maybe the amp draw, I have a 327 with a griffin alum. rad and dual spall 11" fans 3000 cfm and runs very cool. A lot of electric fans are over stated as to true cfm my dual spal fans draw about 24 amps It probably take around 18amps to get 2700 cfm out of a 16 in electric fan. You may not be moving enough air Ed ke6bnl
