Poor Hot Start Solved ?

Ever since I have had the car I have dreaded stalling, as trying to start a hot engine has been very difficult.  As discussed at the post here, there have been various suggestions put forward.  I thought that the extra earth strap would help, but unfortunately it soon became apparent that it wasn't the answer.

Another suggestion made was on a radio show, and that was that the starter motor was getting hot and the resistance in the windings was going up, hence the poor cranking.   I could see the logic of that as the starter motor is hidden behind the engine with no air flow over it.   So I decided I would experiment with adding a pipe to provide some ram air cooling to see if that would help.

 Here is the initial try, taking air from just in front of the engine and funneling it vertically down onto the starter.








At first try it seemed to work.   After a long drive and with the engine nicely warmed up she cranked over a full speed when I tried a restart.   Only time will tell. 

Update:   4 x Hot Starts today, all cranked over at full speed.  Looking good.
