[Vwdiesel] Vwdiesel Digest, Vol 43, Issue 2

[B & R Decker]

Hi David;
	Which tranny do you have. The US Rabbit diesels with 5 speeds that I
have come across have about as tall a tranny VW made that fit them. An FF or
FN made after mid 81 should have a .71. Previous to that they had a .76.
Changing the two won't make much difference. Less that 300 rpm at 80 mph.
Unless you have a good tail wind 80 is pretty optimistic with an N/A diesel.
Perhaps your speedo is off close to 10 % which is somewhat common in Rabbits
with 5 speeds. The Sicrocco.org web sites gear chart gives the following
RPM's with 175-70-13 tires for 80 MPH .71 top in a late FF or FN is 3279. 80
MPH with an early FF or FN with a .76 top is 3510. If someone for some
unknown reason slipped in a 4K tranny from an 84 GTI gas Rabbit then you
would have a.91 top and RPM's would be 4203. Check the letter code on the
bottom of your tranny's bell-housing and we would know more what was going
on.	
	FF 5 speed Trannys are fairly easy to find at least around here.

Ahh, but I do live in the prairies.  And it was on the
prairies that I was driving whilst thinking this. 
(though there are some hills that, while not terribly
steep are long enough to cause the NA motor to slow a
bit if it isn't properly wound up.)

It was while driving 80 that I was thinking I'd rather
see the RPMs closer to 3000 than 4000.  

Also, I do have a NA motor, but am thinking about
adding a turbo kit to it and just keeping the tuning
to low boost.  Just to help the engine breathe a bit
better.

Finally, it was less not removing the trans than
finding a whole new one.

David
