Hey all,
There have been a lot of questions about the need for a boost compensator on a turbo'd 3B. Although it doesn't NEED one, there is something someone on this board mentioned to me in my 3b swap writeup. If you fit a governor spring from a 1977 240D mercedes pump, it will act like a boost compensator. The spring is a bit longer(25-30mm) and is spun from a thinner wire (.5mm smaller- 1.5mm)
I am told this gives a better fuel curve for a turbo application and stop the smoking at low revs before spool up.
Now, I have had a hell of a time finding this spring, but some nice chap on a merc board gave me the mercedes part number for the spring itself (lucky!)
If anyone is interested, they have to be ordered from germany, and run about 9 bucks from the dealer. guy says about 14days delivery time. Im gonna go for it.
this is the part # for the spring
A0010740393 I am told sometimes the A is left out. you can order it from various merc parts sites, but they are mostly in the UK and Russia.
If anyone wants one Im going to the dealer tommorow. Ill check my pm's and this post before paying.
Cheers All!
