I have a 1.8i V40 (non-turbo, non-GDi). On this web-site, under Induction Tuning, it mentions that on smaller engines, replacing the airbox for a competition filter or Cold Air Induction Kit can actually LOOSE you power.
Why is this?
Why does this only happen to smaller engines?
ChipTuning (Volvo tuners) also told me that replacing the airbox will loose me power, but they won't reply to my enquiries about WHY this is the case.
I have modified a scrap airbox base, taking out the hot/cold air flap and replacing the induction 'flute' tip with a larger bore duct (in both cases to reduce any restrictions in the airflow). In the light of the potential power losses mentioned previously, I can't help feeling that I'm again loosing power!
Can someone tell me why / how smaller engines loose power when they have their OEM airbox replaced, when larger ones positively benefit from it.
Thank you, fine Volvo Peeps.
