Has anyone needed to do any mods to thier starter motor to allow them to spin a modified motor faster? T1.

If you have your motor turning over very slowly it could be that the starter is worn out and heading for failure, if it is new and does the same get a relay fitted, you can also get the starter from the early T2 buses that ran a T1 motor they are larger and have a little more torque, so I was told. When fitting a new starter make sure that the bush that fits into the box to support the starter is not worn out or missing completely, this will lead to premature starter failure. I had no problems turning over a 2021cc motor with 9.2 CR with a standard T1 starter.

It's in for repairs at the moment so I'll see what happens when I put it together again.

Is there a specific relay that must be used?

If thestarter isnt good enough, Ifound a Bosch starter at Diesel Electric in Parow, that is rated at 1.4kW and fits the stock beetle 100%.Dont know what the stock starter is rated at, but I have had one of these and they are great

I know this is gonna be difficult for you TonyZ but do you have access to the 10 digit part number? I spoke to Anthoy @ Diesel Electrical and he cant find a listing for it, but said he would do some homework for us IF we can give him the part number.

Get the starter from a 411 automatic or bus auto they are the strongest
Alternatively look for a starter with 4 brushes
I use a six volt starter on my test bench it is the strongest you can get
I machined the shaft down to 12 v size and used a 12v bendix and solenoid ( it has been working for 5 years now.)

I saw the starter by luck... They got a A3 size poster with pictures of various starters on it. Thats how I saw it... 1.4kW for the aircooled beetle

Thats all I can do from here

The guys that are reparing your starter will be able to help you out with a relay, I'm sure they will even show you how to wire it all up.
