When I pulled the Dawes apart last week, the only thing that I could see wrong was that there was a reasonable amount of oil in there. I didn't stretch the spring, just cleaned and re-assembled.Leave spring as is, what Dawes do u have "Brass coloured body" or "Black 3BarRacing"?
I'm still using the original hose clamps that Nissan use on the turbo pipes, would it worth using better ones? If so, what type?If clamps tighten securely they should be fine. Check for splits/cracks etc in hoses and make sure they fit tight (clean away oil residue.
The vacuum hose I'm using is 6mm, but it's softish. Could that be being sucked closed? I noticed it's way softer than the original vacuum hose. I prefer 3mm ID hose and secure with small cable ties
Can anyone remember how to set the needle valve? I can't remember the procedure. I didn't do this the other weekend.
As I have said last week _ In 3rd gear, hauling @ 3000rpm (with needle closed) and when no limp (approx 15-16 psi) open needle valve so lever is just resting against stop screw or spool rate that suits _ do not make it laggy. May need to wind Dawes in a little if boost drops when u adjust needle valve.
Suggest that you remove all boost hoses and wipe off any excess oil residue, clean mating parts and re clamp.
Thanks fort any help.
