A tunable nitrous plate assembly for fuel injected 5.0 liter V8 engines contains a metal plate ( ) that is sandwiched between the upper and lower manifold members of the engine air intake manifold. The plate contains multiple ports ( ) mate with the ports in the lower manifold member and, thereby, lead to individual intake runners of the engine cylinders. Each port includes a nitrous oxide spray conduit ( ) overlying a fuel spray conduit ( ) with both conduits extending across the port transverse to the longitudinal plate axis. Fittings ( ) attached to the plate exterior couple an end of respective spray conduits for fluid communication with appropriate nitrous oxide and fuel supplies. Replaceable calibration jets ( ) installed in respective fittings ( ) in series with the supply lines are selected so that the horsepower generated by the engine cylinders is balanced.

Nitrous plate system for fuel injected engines

A nitrous plate ( ) includes four end-fed nitrous oxide spray conduits ( & ) positioned coplanar in the plate passage ( ), supported at one end by respective walls ( & ) of the plate with closed distal conduit ends positioned near the center ( ) of the plate passage. Two conduits ( ) are coaxially aligned with their closed ends in confronting relationship across the central axis of the plate passage. The remaining conduits ( ) are coaxially aligned with closed ends in confronting relationship across the central axis to the passage and are oriented perpendicular to the other conduits. Four fuel spray conduits are included in a separate plane and are organized in the foregoing way. The distal ends of the spray conduits are mechanically linked together by a junction block ( ).
