Posted January 15, 20187 yr comment_539787 Hi! Im thinking of installing an airbox or an heat shield (haven't decided yet) on my Triple carb setup and wanted to see your solutions and what (if any) difference it made. //Andreas Link to comment https://www.classiczcars.com/forums/topic/59369-triple-carb-airboxesheat-shields/ Share on other sites More sharing options...

January 19, 20187 yr comment_540253 Getting the right amount of air to all three carbs using an airbox that hasn't been designed to do so could cause performance issues and lead to engine problems due to A/F ratios. If you look at the ITG fiberglass or CF boxes they have a taper to them that speeds the flow up as it moves towards the rear carb. A non-tapered box could end up having you jet each carb differently. Depending on the box you would need to select a shorter velocity stack. A foam full length ITG filter out performs the ITG box (based on dyno runs@Rebello's shop). I have my headers heat resistant powder coated (inside & out) and use an under tray heat shield as well. The street and race cars both have louvered inspection doors and you can feel the heat coming out.

January 20, 20187 yr comment_540279 That’s interesting fact. How about smell? Is ITG box less fuel smell than foam filter?

January 20, 20187 yr comment_540282 I'd look at what the performance cars of our family did. I'd like a ps30 style airbox. Link to comment https://www.classiczcars.com/forums/topic/59369-triple-carb-airboxesheat-shields/#findComment-540282 Share on other sites More sharing options...

January 20, 20187 yr comment_540284 If you jet without an air filter, then add one that is restrictive, it will act like an old fashion choke and move the manifold vacuum further up the throat of the carb and cause richness. Make sure your filter flows freely and check a/f after adding.
