UPGRADE KIT
(P/N 70067-70068)
Dyno testing was conducted using a mildly modified 500ci engine.
Modifications included an Edelbrock intake manifold, dyno headers and
improved ignition. These tests were conducted using 950 psi of bottle
pressure and 6.5 psi of fuel pressure. Suggested timing is just a guide-
line, engine component modifications may affect final timing set point.
Edelbrock suggests an NGK spark plug with a heat range between -9 and
-11 as well as 110 octane or higher race fuel.
The Victor Jr. Series Nitrous Systems are intended for use with
single plain intake manifolds only.
Your upgrade kit comes supplied with longer 6AN lines to split from the
feed line to the solenoids, and longer lines to extend from the solenoids to
the plate.
Note: It is important to route the 3AN to 4AN hoses to jet fittings in such
a manner that the 1st stage jetting feeds a spray bar from opposing ends
of the plate while the 2nd stage jetting feeds from opposing ends of the
plate 90 degrees apart from the 1st stage. See the diagram at left for a
sample recommended installation.
