Boxer coolant hose

You're right. The stat should be fully opened well before boiling temp.

I used hose from NAPA auto parts, but I'm sure any high quality will work.
For the hose that comes off the bottom of the stat housing, which flows coolant back to the inlet side of the pump, instead of using a straight hose and bending it, I picked out a preformed hose with close to the required bend in it, then just used that section of hose trimmed to fit.

 

i will be eager to hear if this works! i will hope for the best..then i will follow suit.

Sounds like it was your problem, one note is in the WSM Ferrari specified to drill 2 small holes in the T stat to reduce cavitation on the top and lower pieces.

 

On the BBi cars, a full bypass type thermostat is used...Hence, this particular modification does not apply. The 365 and 512 cars used a drop-in type thermostat, whereas the BBi used a self-contained thermostat unit (BMW-style). An interesting note that both the 365 and 512 cars can be updated to the full bypass type thermostat using a "kit" from Ferrari. I did this modification on my car to improve water flow and reduce vibrations from the cooling tubes which run the length of the chassis.

I would like to see a pic of a $600 thermostat, they are usually a $30 item so I guess the yellow box is $570.

 

let daniel quote the part. he may have a better line on part and price.

I used hose from my local motor parts shop cut to size, but I dont understand why a stat costs so much, Ferrari UK classic parts list the stat for the BBi at £68.40 sterling plus sales tax @ 17.5% its part no #106393

Hi Ludwig, Just a quick thought on hose to use any good hose is probably fine but, I have used the blue silcone hose, which is kinda pricey but lasts forever, or the Gates green stripe hose that you can get at most parts houses. Regards, Vern

 

If you are using silicone hose you must use good quality s/s hose clips that are sleeved, normal clips may pinch through the silicone.

I have used Pegasus Racing Supplies 1-800-688-6946 the brand name is sfs performance hose. Have them send you a catalogue. And you do need to use a proper type clamp. I'm sure you have seen how some clamps have the track holes in the clamp band? Don't use them. Anyway Pegasus will have the clamps you want. Regards, Vern
