Title: okay, I need a compairson, RPM wise
Post by: camboscams on June 22, 2009, 09:53:23 pm: So i recently drove my 81 rabbit 2300 miles on my new td 1.6l. The entire way i was doing about 70-75 mph. i have the 020FF trans, and I'm wondering what are you all's rpms with this set up at that speed. I was blessed with a clock insted of a tach, that way my i dont feel as bad when i rev it up because i dont know the rpm. Overall the car did great, averaged about 5psi the whole way and ran pretty cool too!
Thanks Cambo

That link he posted is the way to go.

Post by: Smokey Eddy on June 24, 2009, 05:13:57 pm: So at 110km/hr im at 2717rpm .... That seems a little high ... shouldnt it be more like 2,200? Where is it printed on the trans which one it is? I can never assume anything on my car is ever original :P

2200 rpm is ideal but most mk2 transmissions only do 2800 rpm minimum for that speed. only the tallest (CTN) will run you to those low rpms

On the bottom of the bell housing is a flat spot with the code and coded date of the tranny stamped into it.

I have my doubts on that one. You'll be lugging the motor pretty bad
