F 40 optimum water temperature

Dear Comrade coachi,

Will you elaborate a little further, please? What exactly is your concern - is it that you believe there to be a problem with a cylinder head gasket, the water pump or perhaps something else? The water temperature on my own motor car, a 1992 model, does vary significantly with the extent of the ambient temperature - as of course does the oil temperature. So please let me know what you believe your problem is and if I am unable to assist you directly (I am by no means an expert) I can enquire at my local dealership on your behalf and I feel quite certain that they wil be able to provide a list of probable resolutions.

With kind regards,

Dear Comrade coachi,

Are you situated a long way from someone who has expertise with an F-40?

I should be pleased to speak to my Ferrari dealer tomorrow if this would help. It would be foolish of me to proffer advice as my expertise is negligible. Furthermore the ambient temperatures within England are presently so much lower than in your clime to make any comparison of no use whatsoever.

Let me know please.

With kind regards,

Dear comrade coachi,

With regard to my sojourn to London today and particularly the travail within the city itself.

I can confirm that at no point did the temperature gauge of the F-40 exceed
ninety five degree's. For the most part it was stable at ninety degree's. The ambient temperature here today was circa seventy degree's fahrenheit and it may well be likely that the ambient temperature in your situation may be far higher. Certainly, your water temperature is far higher than that shown on my cars thermometer today. Could it be that your gauge is reading incorrectly as I cannot even begin to understand how your temperature could be double that of my car?

I am sorry that I cannot help further, but my expertise in these matters is not at all great. However, I do hope that everything is resolved to your satisfaction very quickly.

With kind regards,

Dear Comrade coachi,

Yes, I do understand your disappointment that none of your countrymen have assisted on this post. However, it would seem from the inordinately low mileage of their cars that many of them do not drive their cars at all. Therefore they would not be able to proffer any practical assistance - so don't feel too badly about this.

I am sorry that I neglected to inform you that the cooling fans on my car switch on at the aforementioned temperature of ninety degree's which seemingly accords with your car. It would seem therefore, and please, I have no real expertise in these matters, that your car, on the face of it, does not appear to be running overly hot. Which, if this is indeed the case, is very good news indeed.

With kind regards,

Surely the nearest authorised Ferrari dealer can be helpful?

PM sent. not much help, but i'll check exact temp next time I drive her, and let you know.

 

Ok, 195 is normal. If it is a cool day, 175 can be seen. A F40 will heat up if driven slowly even in cool temps.

Extremely hard driving on the track in summer will yield 210 to 215, I never had a true overheat issue even in the most extreme cases.

You are perfect at 195.

 

Hi Coach,

I drove mine around a bit yesterday....The temp gauge was reading 195
After I backed in to the garage, before shut down, the cooling fans came on and at idle the temp dropped to 190.
Hope this helps.

Joe

PS. I suspect that your seeming loss of boost would be attributed to the hotter summertime temperature.....Lets look into air to water intercoolers....

 

NA cars are effected by the heat even more....consider yourself lucky LOL.

 

Coachi,

Tonight I took the F40 out for a good "seeing to". I added a splash of fuel and off my son & I went driving fairly hard with the turbos spooling up and 'wooshing' away repeatedly with every shift. It was a spirited dive, BUT the key was that it is a cool evening at just 70 degrees on the Pacific Coast. The needle never went above 180 proving the other's theories that these cars run cooler in the cool weather, and hotter in the hot weather. BTW, in the cool evening air, the car felt like a rocketship. Hope Ive helped.

cant agree with that.

every turbo car ive had (or my friends) has been way more affected by ambient temerature than any n/a

i always thought this was generally well known

 

Cooler air = Denser air= more efficient combustion.
With so much heat in the engine bay of the F40's ...I doubt the intercoolers are doing what they could if located in a better/cooler environment.

The heat coming off the header tubes on the Enzo, rising up through the vents, is viciously hot....IMHO, the car needs cooling/exhaust fans for the engine bay.

Mine will hit 195 in hot weather if I'm in traffic, but hovers around 180 as long as I keep her moving.

 

how about lagging the headers and turbos ?
that should help drop engine bay temps

 

Not quite true, you just might notice it more then a NA car. Look at how forced induction cars perform better at higher elevations then NA cars. Same basic theory.

Bottom line, excess heat effects ANY engine.

 

This is untrue.

N/A cars and FI cars will both suffer with higher ambient temperatures, but it's a totally different effect to the altitude thing. FI cars do not suffer much at altitude whereas NA cars do. This is because FI (turbo) cars build a given amount of boost in relation to sea level - so if you run 15lbs at sea level you also run the same density (higher actual boost pressure) at altitude. NA cars don't. NA cars get less dense air at altitude.

The FI car is going to have a higher delta between intake and exhaust temps at the turbo at altitude than at sea level, which decreases the gains a bit, but both will be affected by temperature, IMO the FI car moreso.

But the altitude thing is very different than the temp thing in comparing performance of NA vs. boosted cars.

 

Humm, that's what I said?
I said NA cars are effected much more then FI cars at higher altitudes....

 

concur @ 195 and lower when cruising
