Air Intake Air Ducting

[TomoHawk]

Can you get the plastic Air duct tube that I see in the FSM for the 280Z? I think it might be good to have one because otherwise it's sucking hot air from the underside of the hood. Maybe you could even substitute something else. Other that that, trying to get cooler air to the intake system requires a ricer-type c.a.i. system.

thx

correct me if I'm wrong but the plastic air tube that connects to the end of the filter box just extends it and DOES END UP PULLING HOT AIR FROM THE ENGINE BAY. Dont know if they are available or not, but should be lots of used ones aroun with the peeps converting to the CIA.

That depends on how you look at things. There's probably more pressure in front of the radiator, and behind the radiator support is less rain, which is why I think the tube was used. There probably isn't any one best place to get air, so you need a good filter to shed water and continuous fresh air.

If you wanted to do a search on eBay, what words would you use?

thx

Got me on that one, but if u cant find one, give me a buzz, might have one or 2!

TomoHawk,

Autospeed did an excellent series of articles on intake modifications.

Thanks Will.

I'll go look into it.

also, thanks to TBK1 for the offer. I think it might be easier to just go with a c.a.i. system. Unfortunately, as much as I think about it, I just can't seem to think of a place that has high-pressure cool air, that's not in an awkward place, like the bottom of the windscreen (Will's favorite spot).

I keep coming back to the idea of a cold air box above the engine, like muscle cars had.Again, the plumbing would be compromised with sharp corner(s).

thx

Do you mean Autospeed on here or Zcar.com, or where?

Will, you gotta turn off your computer, so you'll have time to do the stuff you need to get DONE! I loaned out my laptop once for a week, and you would NOT BELIEVE how much stuff I got done!

Yeah, I found it a while ago with a little searching, but thanks. there's not much directly pertaining to a 280Z, but maybe they some stuff on intake mods like you said.

thx

Instead of having ALL the air going through the AFM, do you think you could split things so that you get some through a hood scoop and some the regular way? One probably has a higher pressure, but by splitting the source, you could get MORE air though at lower pressure. You'd have to do a funky recalibration of the AFM tho.

Yeah, they have a bunch of articles on Intake mods, filters and such, but you only get to read enough to get interested, and then they tell you to subscribe to get the rest of the article...

So you'd have unmetered air in your system. And you think this would improve things how? :stupid: Now I'm sure you've seen as many or more posts than I have about vacuum leaks and the like in a FI motor, so why make one?

IF you did manage to do it, the only way would be to make sure the rates of induction where exactly the same at any given time, which defeats the purpose of the exercise in the first place.

I wonder sometimes
