6 Volt High Torque starter motors

Has anyone experience of the 6 volt high torque starter motors versus a normal motor? are they worth the cost? 
Any thoughts from the 356 community?

No experience with high torque just the standard system which works very well if all parts of the system are as the good Doctor prescribed.
Good battery, clean and tight electrical connections, a good Bosch starter and a good starter bush.

Thanks John, but with a new battery, power cable and connections 4 years old, starter motor 56 years and 168000 + miles old. I think the original brushes are worn down or not making good contact with the commutator so the starter motor needs reconditioning or at least replacing the old brushes, which is not a simple job.
The high torque starter motor looks enticing as a replacement, less current usage, faster cranking = better starting?

Hi Robin,
 
I don't have experience of the Hi Torque starter, but if you decide to have your original re-furbed speak to Rob at Broadway Electrical 01375 372782. He did a good job on mine a couple of years ago.
 
If you want to test the starter you can hot-wire direct to the battery with jump leads eliminating all the other variables - watch for sparks though (a switch would help here).
 
Keep the faith

Thanks Hugo, I ordered the Hi Torque starter from Roger Bray Restorations which arrived in under 24 hours!
I shall report the results as soon as I have fitted it. Thanks for the info on the restorer.

I have received the 6volt HighTorque starter motor and have fitted it onto the car after removing the old original Bosch unit.
Although it is a bit of a fiddle because of where it is located it went in relatively easily and I even found a way to hold the "difficult" bolt in place using mole wrench and a block of wood. Connecting the electrics was straightforward and turning the key produced an unusual sound in that the electric motor part is a smaller high revving motor that is geared down to drive the pinion which pre-engages the flywheel mounted teeth and drives the engine to start it. The existing bellhousing mounted nose bearing used for the Bosch unit is not used and remains in place, until one might want to return the original unit. The turnover of the engine is noticeably faster than the standard unit.
I am pleased with the result. 
I would love to show photos but I have no idea how to download them, this system is not as easy as on the 356 Registry site where you just attach the photo from a folder like it was being attached to an email.

I'd be interested to see photos as the slow starting on my 356 is one of it's most annoying habits!
 
To add them click on the '(Open Full Version)' link next to the Quick Reply: title, and then select Attach Images as per below
 
 

Then do 'From Gallery / Upload' and then click the bottom link 'Upload images from your computer'

That's how I did the image above and it looks like you can only do 1 attachment per post so you will need a few replies :)

Hope these photos help.
I think I have almost got the idea of how to post photos.
But how does one remove the ones that are duplicated ?
Can someone who might be reading this please make it easier to post photos.

Thanks Robin - photos look great. I'm going to attempt to get my old one out of the car first before I order one as that sounds like a 'fun' task from reading around, but then will definitely go the same route
