Eric, How long are your tubing lines from the solenoids to the nozzles and
are the NOS and fuel lines the same length? I think that your initial lean
condition may be because the NOS under 900ish psi reaches the nozzles faster
than the fuel 5.5psi does. As long as it is very short in duration I would
not think this would be a problem. Also I have tapped just before (actuall
attached to) the fuel solenoid a "T" with a valve and line that goes back to
the tank. I can open this valve and purge out all the air in the line and
pump. Usually I can hear some air cycling through the pump the first time I
do this at the track.
As far as using the drain plug, I would NOT do this. Remember all the crap
that ends up in the tank goes to the bottom. My NOS system is the last
place that I want all this crap to end up.
Now that I have got my frame, fork, modified Delrin mounts all done I am
ready to head back to the track to see if I can handle her under full boost.
The problem now is that the back tire breaks loose just when the V-boost
kicks in so I will have to wait for a tire first or I will be waisting my
time. You listening sweetheart??? :-)
