V8 Air intake ducting

[Deeman]

Hi Guys - I still have the manky old ribbed fabric ducting between plenum and AFM and AFM to induction pipe (the one with huge 45 degree elbows at each end!). Is it really worth upgrading to Silicone jobs, and what sizes did people use? ACT seem to do stuff for the Chim/Griff but it doesn't look the same shape/set up in the v8s. Saw Barky Choc stating there is a need to find a 80 to 70 converter. Just wondered what sizes people have used and which company, when they changed the ducting? Pete

Max - you've got the same "Arkansas chug a bug" type of chimney stack intake pipe as I have, unlike Joe's curvy job - there is also a weird link between your plenum and AFM joe - a tornado arrangement perchance?. The "talk" seems to be about smooth air flow equalling torque and a couple of horsepower - does smoothing it all off really help? Some great shots Joe (and Green v8s - phenomenal engine!). Come back to where did you get the silicone and what sized bores - 80 to 70 converter in short space, seems an odd one.
