Cold air intake VS. Individual stacks? (ITB)

I'll also need to address how air comes in and exits the engine compartment, like you mentioned.

Bingo! The Kinsler unit. Very nice!!

Where do the air intakes drop down to right now? If you remove those can you replace them with a fabricated "scoop" to get air from the same areas and just flood the engine compartment with good cool air?

itbs with properly designed airbox and a big enough feed pipe will be superior to open filters in the engine bay

look closely at the McLaren F1 engine above

those surface area calcs are bunk, remember that one cylinder will breathe at a time, so the surface area of the single throttle plate is fine, ITBs work by allowing pulse tuning/ tuned lengths. however with a 90 degree v8 the pulse tuning doesn't work as well as something like a ferrari v8 with a flat crank

I don't really know which direction to go, back and forth. The old set up worked so I'm thinking (with my wallet) maybe fix the box?

I don't know?

Bingo ! Just fix what you got, is the crack on the top, if yes maybe switch the box to teh other side and then it is on the bottom, you wont even be able to see it.

Good idea, thanks. Harrop did locate me a set if I need it (them- need to buy the set). Still doing research on the cold intake vs. the stacks (trumpets) Seems to be lots of varied theories.

Legend thanks Maclaren I'm sure did the research, sick looking engine!

Dave,
Did you make any decisions on the intake yet?

[monza]

I did here you go: (sorry three year late reply...my kids- 3 and 5 and work took over priorities for a while, I'm back working/playing with FuEL)

I cut the existing boxes up and rebuild them bigger and way stronger the 3" has gone to 4" on both sides and 2" fatter through out every where else. Now to just make some 4" tubes running to air filters in similar location as the old air filter intakes...

Slowly tweaking other things as well.

I noticed this on a Ferrari and how they reduce air intake turbulence, the red extensions do nothing except mellow out the air flow. Sorry for the Ferrari pic but I thought it was interesting.
