Proposition 65
AVERTISSEMENT: La manipulation de pièces de véhicules automobiles de tourisme ou hors route peut vous exposer à des produits chimiques tels que les phtalates et le plomb, qui peuvent causer le cancer et des problèmes de reproduction. Pour minimiser l'exposition, entretenez le véhicule dans un endroit bien ventilé, portez des gants et lavez-vous les mains.
Ce produit est destiné à un usage hors route uniquement. L'installation et l'utilisation sont à la discrétion et sous la responsabilité du propriétaire du véhicule, conformément aux lois locales et fédérales. Cliquez ici pour plus d'informations.
Le collecteur Killer B Motorsport Holy Header a été développé à l'aide de logiciels de CAO et de simulations à la pointe de la technologie afin de déterminer la conception optimale pour augmenter la puissance autant que possible sur toute la plage de régime. Les primaires ont été rendues aussi courtes que possible, de même qu'une secondaire unique, ce qui diminue considérablement le volume du collecteur, permettant à la pression des gaz d'échappement de s'accumuler rapidement.
Non conforme à la norme CARB
La conception symétrique 4-1 maintient une vélocité d'échappement élevée et constante à mesure que le régime augmente. Vous pouvez vous attendre à un temps de réponse nettement plus rapide par rapport aux conceptions à longue primaire/double secondaire. Vous remarquerez immédiatement une amélioration de la réponse à l'accélérateur/à la suralimentation et la capacité de maintenir plus de puissance à des régimes plus élevés.
Collecteur moulé
Le collecteur est en acier inoxydable 321 moulé à paroi épaisse. Le moulage élimine plusieurs soudures, chaque soudure supprimée est une perturbation de flux en moins (turbulences réduites). Le moulage présente des caractéristiques usinées qui garantissent un ajustement TRÈS concentrique des tubes primaires à chaque fois. L'utilisation d'un moulage permet de concevoir le collecteur comme une véritable fusion à haute vélocité plutôt que comme un tube qui ne peut être formé que légèrement, et non idéalement. Le moulage est plus épais/solide que le tube formé et retient également mieux la chaleur.
Primaires courtes de longueur égale
Le Holy Header comprend les primaires les plus courtes possibles sur un collecteur à longueur égale. Court signifie moins de volume de collecteur et un spool up plus rapide.
Conception primaire symétrique
Toutes les primaires du Holy Header ont une longueur de tube ET une géométrie de courbure similaires. Cela maintient les vélocités d'impulsion élevées et constantes par rapport aux collecteurs à longueur égale avec une géométrie de tubulure primaire non symétrique.
Courbes lisses au mandrin
Toutes les courbures utilisent un mandrin pour un flux lisse et non restrictif. Non seulement cela, nous utilisons les plus grandes courbures possibles à chaque emplacement. Il serait moins cher d'utiliser des courbures de 2 pouces partout, comme d'autres le font, mais cela ne donnera pas les meilleures performances.
Construction en acier inoxydable 321 à paroi épaisse pour une longue durée de vie
Le 321 est allié au titane et coûte plus cher, mais c'est le matériau idéal pour les applications turbocompressées à haute température. Les températures sur les voitures turbocompressées peuvent facilement dépasser les limites de l'acier inoxydable 304 au point de le rendre cassant et de le fissurer. L'acier inoxydable 321 a une résistance et une ténacité plus élevées à haute température. Il a été développé par l'industrie aéronautique spécifiquement pour résoudre les problèmes de fissuration des collecteurs en acier inoxydable 304. Killer B Motorsport est la seule entreprise qui fabrique des collecteurs entièrement en 321.
Haute rétention de chaleur
L'acier inoxydable 321 conduit beaucoup moins de chaleur que l'acier inoxydable 304. Les primaires courtes et les secondaires correctement dimensionnées absorbent également moins de chaleur des gaz d'échappement, augmentant ainsi l'efficacité de la turbine. Les collecteurs à grand diamètre de tuyauterie exposent les gaz d'échappement à une plus grande surface, transmettant plus de chaleur et réduisant l'énergie d'échappement. Vous pouvez également revêtir de céramique ou envelopper nos collecteurs (et conserver la garantie) sans dépasser la plage de température.
Connexion V-Band Up-Pipe
Pourquoi V-Band ? Rapide, facile, pas de joint, pas de fuites et un alignement concentrique parfait des tubes pour aucune perturbation du flux, que demander de plus !
Up-Pipe inclus
Bien sûr, il est livré avec un up-pipe ! Ce collecteur a été conçu comme un système complet. L'utilisation d'autres up-pipes ne ferait que compromettre les performances, et personne ne veut cela.
Fonctionne avec les carters d'huile OEM EJ25 et le carter d'huile en aluminium Killer B Motorsport Performance !
Convient à tous les moteurs WRX et STi de la série EJ. Conçu pour fonctionner avec un turbo en position OEM.
