Guys I am a new-comer to the forum and have been reading thru the previous posts with interest. I am a month away from getting my 6.5 optimiser n/a conversion back from Brunswick. I have however already started to plan the installation of either an additional oil cooler or a fan cooled unit, plus have selected a couple of bonnet vents for heat removal.
I read some interesting history regards the effectiveness or otherwise of bonnet scoops and decided since hot air rises and air is being forced into the front of the engine bay already it's counterproductive to change its direction.
I am also looking out for comment regards the effectiveness of the standard safari snorkel on the 6.5. Mine is fitted with the 76mm inlet and ram head. I have a small Donaldson dust spinner however the literature suggests I need a unit to handle at least 300cfm, and the little one won't. Also as I suspected this style is suited more sor statioary plant than 100kph travel - what are your thoughts? I don' t know if my conversion will come with the Donaldson under bonnet canister or the other washable style element - having a brain freeze and totally forgotten the brand - expensive but good. I guess as I wait for the toy to return my planning juices start to run amuck. PHIL
