cold air intake on a ghia
I have an EF2 ghia and decided to take some advise from the guys that have direct cold air intakes on their cars. I used the 2 x 2.5 inch pipes tied together for this. (note: i am still using a standard panel filter in my air box). I cut a hole out of the side of the air box to fit them in, pushed the piping down past the engine and brought it around to fit through the housing of my fog lights. I had to remove the plastic wheel arch which sheilds the electrics of the headlights from the wheel to get the piping through. I didnt want to cut a hole in the plastic wheel arch sheild.
The sound i have get now from the engine sounds like a deep drone which sounds pretty good compared to the standard high pitched drone. Its weird, when i plant it in first, it sounds deep up until around 4 grand then returns to its usual highpitched self. (note: this happens in 2nd gear aswell) I have noticed a definite improvement on fuel economy as when i hammer the car around it usually drinks a shitload of petrol according to the computer. I havent noticed much more in performance though, yet the revving feels heaps more cleaner, until it hits 4 grand. The car feels like it pulls heaps more when it hits 4 grand aswell... i know peak torque could be up around thereabouts... could the new air intake piping cause less power?
Can anyone give me an answer to why it would returned to its high pitched self once above 4 grand??
