do88 prestandaintercooler designed for drop-in fit in your BMW M2 / M3 / M4 F8X
BMW M2C / M3 / M4 F8X has a dubbelturbo-motor (S55) that uses a toppmonterad vattenkyld intercooler instead for a ”vanlig” luftkyld intercooler. Original intercoolern has a Tube & Fin core with tankar gjorda of plast that klämts fast. This konstruktion has sina nackdelar because the is benägen to spricka and begin läcka kylvätska in in engine's insug or läcka boost pressure ur tätningen between plasttankarna and cellpaketet.
Our mål when we startade utvecklingen of our nya intercooler var to eliminera all svagheter in originalintercoolerns design and naturligtvis increase prestandan rejält. Under all tests that we utfört under utvecklingen of entire our BMW F8X M2C / M3 / M4 produktsortiment ser we tydligt hur power is directly sammankopplad with insugstemperaturen.
For to few a exakt 3D-modell of it tillgängliga utrymmet for to designa our intercooler in gjorde we a detaljerad 3D-skanning of motorutrymmet in our own BMW M3 Competition. IN our Solidworks CAD-mjukvara laborerade we between flera different designkoncept for our nya intercooler with hjälp of the 3D-skannade modellen.
It slutgiltiga designkonceptet bestämdes after we gjort flera CFD-simuleringar in our Solidworks Flow Simulation mjukvara. IN this mjukvara can we simulera air flow and mäta pressure drop and air/water-fördelning over cellpaktet. We bestämde oss for to not inkludera interna luftstyrningar because flera of our simuleringar visade to they gjorde more skada than nytta. Luftflödet fördelas perfekt over cellpaktet with our tankdesign without inner luftstyrningar that many andra in branschen påstår is good. Our slutsats is to in this case orsakar these luftstyrningar turbulens and störningar in luftflödet.
The slutliga designen has a bar-and-plate core with TIG-welded tankar of aluminiumgjutgods. This provides a sinnesro for all with high power target (high boost pressure). We lyckades use oss of a core that is entire 85% larger than original and also minska (16% lower) tryckfallet. Trots this bibehåller we a drop-in installation without modifieringar. Minskat pressure drop over intercoolern has flera advantages, to exempel to turbon needs arbeta smaller for to achieve begärt boost pressure / bidrar to lower temperature / improves gasresponsen. We has utrustningen for to beräkna tryckfallet in our CFD-beräkningsmjukvara and also mäta this in verkliga tests in our Superflow SF-1020 flow bench. For kylvätskan ändrade we flödesvägen so to the passerar through cellpaketet two gånger innan it lämnar intercoolern instead for a gång that it makes on originalintercoolern.
IN cellpaketet uses we a offset-kylfläns with high densitet on both air- and vattensidan. Flera tests utfördes for to hitta a optimal balans between air- and vattenflänsar for to few maximal heat transfer and samtidigt lågt pressure drop. This provides our intercooler a enorm increase of the aktiva kylarean compared with original.
Because this is a do88-prestandaprodukt has we naturligtvis utfört grundliga tests for to utveckla this produkt for to säkerställa best performance. No compromises have been made.
Everything this hårda arbete we gjort resulterar in a produkt that on a or annat way really will to improve fordonets performance oavsett if it is a standardbil or a kraftigt modifierat monster! On väg, on gatan, on banan, will this intercooler to vara your sanna följeslagare!
