hy,, RAY ,, what do you thing if we use the heather motor fan ( in the motor section ) for to help to cooling the piston head ,,, example ,,, if we put 2 big hose 2" , one on the piston no 1 cover ( on the side of the spark plug ) and one on the piston ,,no.3 ,, with a dual temp électric thermostat 200 d.f. to 250 d.f.on the piston no3 wend we run on the hiway or wend we stop the car for a short time , the électric heather fan continius to run for to cooling the head ,,and the électric thermostat stop the fan to 200 d.f. one thing i d,t know ,, or if you know that ,,, the ,,cfm,,from the motor cooling fan can close the damper door in the électric heather fan , and the ,,cfm,, from this électric fan can geeve a good help for to cooling the head ,, thanks for your suggestion ,,albert

Actually...thats a pretty good diea. It is much the same as water cooled cars whose radiator fan continues to run after you shut down. It especially makes sense on factory fuel injected cars to stop heat soak into the CHT. Let us know how you decide to plumb this. Ray

ray,, for to install this 2 cooling hose that is not a big problem ,,but my most important point is ,,, inside of the fan heather we have damper closing door ,, with a very small spring ,, wend we geeve the power 12 volts on the motor the damper open by the air force ,cfm,, but this air go in the heather box ,, if i put secon set of hose 2" for to cooling the motor head , the crank fan ,,cfm,, can close this damper by the reeturn pressure and the électric fan motor d,t serve to nothing excepted wend the car is stop ,, wen the car run ,if the 2 pressure go in the same sensce, he d,t have any problem ,, my question is ??? how many ,,cfm,, can geeve the crank fan ,, ( for sure that play with the ,,rpm,, ) and how many cfm,, can geeve the électric fan motor ,, if we have compétition in this 2 force ,, that d,t geeve nothing excepted wend the car is stop or only on the hydle ,, there is my interrogation point ,,, but i thing the vw over heathing problem come wend the car is in the trafic or on the slow révolution ,, and if we shoot the air on the piston .no,1,and 3 ( by the élecric fan ) that can affect the mécanic thermostat onder the motor ,, that is a big technick question ,, ouf,,,my english traduction is of,,,
