The Killer Scorpion 450 Plate System is a complete dry plate system intended for V8 engines running Holley type 4500 carbs/manifolds (other applications are available by special order). The Killer Scorpion 450 Plate System is capable of flowing up to 450 BHP (a 900 BHP version is also available).

The Killer Scorpion Plate incorporates the most advanced technology ever applied to any type of nitrous system design. This incredible design not only looks impressive but more importantly it will produce outstanding results on all suitable V8 vehicle applications, even beyond those of our Spider plates.

Its unique design sets it head and shoulders above all other plates, as only the Killer Scorpion Plate offers all the benefits of a direct port nitrous system plus all the benefits of a plate (without the disadvantages of either), all in one compact package.

Other features of the Killer Scorpion Plate include;

·        Direct nitrous feeds to each runner

·        Perfect distribution to all cylinders with equidistant leg lengths

·        Optimised flow path through the Spider to minimise loss of density

·        Individual cylinder jetting option

·        Single entry to comply with certain US specific race classes

·        Open plenum 2 port shape (instead of 4 ports) for maximum airflow

·        Single central feed/divider for balance NA flow

·        No obstruction caused by conventional spray bars as used by most other plates

·        Integral pressure port for sensor mounting for data logging

·        Maximum runner/cylinder filling efficiency from Bernoulli super charging effect

·        PLUS TOP SECRET advantages that NO other type of nitrous kit can offer


The Killer Scorpion 450 Plate System benefits from numerous unique features as standard equipment, which offer substantial advantages over all other options.
