what do you think my old pump had done to it? - Joe - 15-07-2012
right since ive owned my new d'tub ive been wondering what on earth my old pump had done to it, it would continue revving right round to 5700 ish rpm and you wouldnt notice that it wasnt pulling anymore, what do you think has been done to it?

A stock pump will rev that far in first and second but there would be a significant drop in power. Sounds like it has been gov modded tbh
RE: what do you think my old pump had done to it? - Joe - 15-07-2012
it would do that in every gear! fancy taking a look dan?

as Dan says, it had been Gov modded . .

Bosch or Lucas...
If Lucas, it's an old style one that revs like f*ck when you turn it up.

Yea my lucas was the same, limiter was around 5.8k with a very light s1 tune, and the throtle stop removed.

Hmm....what throttle stop would this be? is it easy to remove? Ive turned the fuel up on my Lucas, making 18-19psi, but there is, as Dan! puts it, a significant drop in power at about 4.5k....

Its the screw/ bolt the throtal arm rests up against.
Don't remove it completly, and make sure the throtal works as it should. Also adjust the cable end on the arm so you actualy get full travel.

The screw on the throttle arm, pull it to full throttle with the engine off obviously and it'll hit a screw i you wind that out it can go further
Edit: Chris beat me

Hmm....i might go have a look at this now....

Yours will be a new style Lucas Steve, they will rev pretty shit no matter what you do...

Meh, goes to up 5k now, feels a little strained once its there, but it gets there. Probably wont be taking it that far very regularly!

I got an old style RotoDiesel Lucas on my XUD7TE 205, so you reckon with more fuel it will rev it's tits off?
btw it's un modded thus far...
RE: what do you think my old pump had done to it? - Joe - 15-07-2012
