Hedman Hedman er en amerikansk producent, der har specialiseret sig i headers, altså grenrør, der samler udstødningsgassen fra hver enkelt cylinder og fører den videre ud i bilens udstødningssystem med så lidt modstand som muligt. Mærket har eksisteret siden 1954 og har gennem årene opbygget en solid erfaring med at konstruere grenrør til amerikanske motorer, hvor både holdbarhed og en gennemtænkt rørføring vægtes højt. Grundtanken bag et Hedman-header er enkel: jo mere ubesværet udstødningsgassen kan bevæge sig fra cylinder til udstødningsrør, jo bedre fungerer motoren som helhed. Foruden headers indgår der også enkelte dele til ophæng af motor og gearkasse i sortimentet, hvilket viser, at Hedman ikke udelukkende tænker i udstødning, men også i de øvrige komponenter, der holder drivlinjen på plads under motorhjelmen. Det er dog headers og tilhørende udstødningsdele, der udgør kernen i det, mærket er kendt for, og det er også her, den tekniske detaljerigdom er størst. Et header er i sin enkelthed en mekanisk løsning, men udformningen af hvert enkelt rør, buer og samlepunkter kræver en del erfaring at få rigtig, hvis resultatet skal fungere godt i praksis og ikke bare se rigtigt ud. Typer og udførelse Hedman tilbyder flere forskellige headerudformninger, og forskellen mellem dem handler primært om rørenes længde og deres vej gennem motorrummet. Fuld længde headers har lange, jævnt formede rør fra hver port og giver en ensartet gasstrøm hele vejen til samleren. Shorty headers er en kortere udgave, der fylder mindre og derfor ofte er nemmere at få til at passe i trange motorrum, mens fenderwell headers er formet til at føre rørene ud mod hjulkassen, hvilket kan være løsningen, når pladsen omkring motoren i øvrigt er begrænset. Materialevalget spænder fra almindeligt mildt stål til T-304 rustfrit stål. Mildt stål er det mere traditionelle valg og fungerer fint, hvis bilen holdes tør og velvedligeholdt, mens rustfrit stål i T-304 kvalitet står markant bedre imod rust og fugt over tid. Flere modeller er desuden udført med en samlerkonstruktion uden pakning eller med en kugleledsløsning, hvor rørene mødes i et fleksibelt led. Begge løsninger gør det lettere at tilpasse resten af udstødningssystemet, uden at samlingerne bliver stive eller svære at få tætte. Den kugleledsbaserede samler har den ekstra fordel, at den tillader en vis bevægelse mellem headeren og resten af udstødningsrøret. Det betyder mindre spænding i systemet, når motoren sætter sig ved opvarmning og afkøling, hvilket over tid kan skåne både samlinger og pakninger andre steder i udstødningen. Sådan vælger du det rigtige Hedman-produkt Valget mellem fuld længde, shorty og fenderwell headers afhænger i høj grad af, hvor meget plads der reelt er til rådighed i motorrummet, og hvordan bilens øvrige opbygning ser ud omkring motor og hjulkasser. Er der god plads, giver fuld længde headers ofte den mest jævne rørføring, mens shorty og fenderwell varianter er værd at overveje, når montering ellers ville kræve indgreb i karrosseriet. Dernæst bør materialet vælges ud fra, hvordan og hvor ofte bilen bruges. En bil, der køres året rundt og udsættes for fugt og skiftende vejr, har mere gavn af rustfrit stål end en bil, der primært bruges til bane eller opbevares tørt. Endelig er det værd at kigge på samlerkonstruktionen, da en pakningsfri eller kugleledsbaseret løsning kan gøre det enklere at tilpasse headers til det øvrige udstødningssystem uden ekstra tilpasningsarbejde ved monteringen. Sammenholder du disse tre forhold, ender du typisk med det rigtige valg til netop din bil.
