Hey guys,

Just curious what tempreature your cars run at, Think of you hardest driving and try to remember what that temp was.

When racing, my car runs about 220 Degrees F. Sound right?

Just curious, if I need to I'll get some water weter or something, just to try and drop that temp.

What do you guys think?

Thanks for your help,

Brandon

My 97/4.6 runs between 218-224 in the summer. It runs slightly cooler when it is under 90 degrees and I have the AC on (high fan all the time). Last year when it was like 110 or higher and we had a meet, idling around in traffic it got slightly higher, but not too bad.

So far it sounds like my temp is just normal. Pretty much the car just warms up in the pits, then runs 15 laps mostly at WOT from 2K-5K RPM, and I was just making sure I wasnt heading down a bad road.

Anyone else with input is appreciated,

Thanks Bangster,

Brandon

I seem to recall that the stock settings are:

222 degrees low fan turns on. Turns off when it gets down to 214.

229 degrees high fan turns on. Turns off when it gets down to 220.

Mine is (should be) different because I specified that I had a 180 degree thermostat and I wanted the low and high speed turn on temps changed to reflect that, and so far it seems to be that way, I need to pay attention to the XCal 2 and see if I can narrow down what temp the low and high speed fans are commanded on.

I just have my high speed fan hot wired through a toggle switch, once the car gets up around 160 I turn it on and let it on the whole time I'm racing.

Yeah, I think I remember you posting that, I thought I would post what Ford thought was a good temp to start using a way to move more air to cool it down, and then what temp to really really try to cool it down :)

And I think high speed is 228, not 229.

try lessen the coolant mixture to more straight distilled water ratio. it'll help a lot.

example like instead of 50/50 mix use 20~30 % coolant and 70~80 % distilled water mix. water absorb more heat better than coolant.

maybe cut some vent hole on the hood between radiator and altenator area to let the hot radiator vent thru if rules allowed?

I dont run any of the cowling, where the wipers would normally be, and when I have the fan on, with the car just sitting still, you can really feel the air coming out. But if vents would help move more air, I guess it wouldnt be that hard to cut some holes and put screen under the holes. The way it is looking though, my car isnt running hot to begin with.

Thanks for all the help guys,

Brandon
