great guide. interestingly I was thinking that the outside temps can make a big difference with my car I have also found a needle which I think is a bit closer to to my setup of 998 - 12g295 1.5 rockers 8.7:1 8-10 psi supercharged sc12 A BCG needle I have also shrunk your pic so when it prints is about correct size for a needle. Thanks for all of this info. Station No BCG BDD 1 0.0990 0.0990 2 0.0950 0.0962 3 0.0914 0.0937 4 0.0886 0.0907 5 0.0837 0.0850 6 0.0786 0.0795 7 0.0736 0.0753 8 0.0665 0.0720 9 0.0582 0.0694 10 0.0493 0.0673 11 0.0414 0.0653 12 0.0331 0.0635 13 0.0331 0.0618 14 0.0331 0.0602 15 0.0331 0.0585 16 0.0331 0.0570 gr4h4m, are these the measurements of a standard bdd? i am starting with a leaner needle as a standard bdd was too rich at cruise befere but was perfect at light accel, now i cannot find the needle :/ i bodged this together today for measuring and marking out needle stations, just paper stuck to some cardboard and pushed the needle into it for somewhere to sit, very easy to do and makes it a lot easier, i just stick a bit of cardboard under the end of the needle to raise it up to measure.

It worked very well indeed but its not eactly practical to have it on all the time because for 1it sticks up 6 inch out the bonnet and for 2 at 25psi it pops the clear cover off the damper and it shoots of like a rocket so im working on v4 this is how far i have got atm.. run out of electrical supplies

resurrecting from the dead. Why can't I see the photos on the www.terryhunt.co.uk webpage? It keeps asking for a login.
