just wondering if any one knows how to get the turbo to kick in sooner on my old pump it used to kick in around 2500rpm but now on the new pump is well over 3500rpm the pump came of a d24t engine and mine is the d24tic i noticed there is a screw in the very top of the pump that seams to be in further than on the orig pump its just that i miss that extra oooomph to leave most cars behind

Is this the 6 cylinder VW engine? A lot of this should apply to your engine Worth getting a cheapo boost gauge just to check on things when doing this. It will mention EGT gauges quite often, but as long as you don't have thick heavy smoke you should be ok, turn the fuel down slightly lower if you tow or have heavy loads up steep hills etc

I think the problem probably is the screw on the top. This is the boost enrichment device, it delivers more fuel when the turbo comes in. If the turbo is still original and you've just changed the pump then chances are it's just the pump that needs setting up. Are you sure the pump is timed up correctly? Basically the pump is very complex and controls more or less everything, it has to be set up perfectly or the performance/economy will suffer, this applies to any mechanical diesel.

the timing is bang on but was told that the pump was of a turbo but with out the intercooler so they have to turn the turbo down due to heat generated my car used to go like the clappers so if i adjust the top screw but just rember how many turns i alter it i should be ok then lol

Yep have a fiddle with the screw, if it doesnt work just put it back to where it was. I dont see what they mean by 'turned the turbo down', as far as i know its fixed. The TIC uses a different turbo. Just sounds like it's not getting enough fuel into it on boost to take advantage of the extra power.

hi there i adjusted the screw and the car is back to how i first had her on the non intercooled engines they turn the pump down to reduce the heat genarated in the compreasion of the inlet air but my car is now running bamg on i was just a little unsure of what the screw adjusted and that was why i wanted the info

Craig, this is what it says in the book about checking and adjusting the amount of boost from the turbo. It gives no info that I can see about changing the revs at which it is activated. If you can understand the diagram on adjustment please explain it to me! john
