2-STAGE VICTOR
JR. UPGRADE KIT
(P/N 70067-70068)
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.
Dyno testing was conducted using a mildly modified 500CI engine.
Modifications included Edelbrock intake manifold, dyno headers and
improved ignition. These tests were conducted using 950psi bottle
pressure at 7.5psi fuel pressure.
Edelbrock recommends using Champion C-64-C or equivalent
spark plugs as well as 100 Octane or higher racing fuel.
The Victor Jr. Series Nitrous Systems are intended for single
plane manifolds only. Do not use a dual plane manifold with
the Victor Jr. Series Nitrous Systems.
