ok well i cant find what i am looking for but i did see it on this forum, i saw a pic of a nb with the cai located on the left side of the engine bay, it was red! not sure who it was though, i wanted to get something like this done myself and wanted to know how it was done etc any help will be appreciated

FOUND IT! how did he do that :shock:

anyone know if the wires are extended ? what about teh airflow meter being moved?

I think this was a dodgy day solution
can anyone varify???
looks like the wires were extended and there is also a sensor inside the stock airbox on the opposite side to engine that had to be moved
if you look closely it is in the bend of pipe (in bevan's) there is a hole there for this placement
edit:
found all the pics so here you go

wow, cheers SM.

just out of curiousity, does that make any performance gains? seeing that its away from the extractors (which are generally the hottest thing in the engine bay) it should get some cool air ? Mania have that K&N thyphoon kit, but i think it would be worse having the filter exposed when set up next to the extractors then having it sealed like the stock airbox, eitherway i hate the rubber hose on the airbox, it has to go !

no idea what the gains would be like (I've only dríven stock mx-5 NB's)
would be interested to know though
doesn't look like too hard a DIY job

and I'm guessing the pipe is painted white to help reduce heat as well 'shrug'

It's white cause it's dunny pipe PVC! :mrgreen:

well that definately is a dodgy day :lol:

so anyone know the gains out of this? its far FAR away from the extractors which is what i want

Bevan found that it used considerably more fuel than the hot side version and reverted back to that, I think the power levels were similar - at least there wasn't a huge difference between the two. It was 'cost effective' though, a dunny pipe elbow and a couple of lengths of wire and connectors... can't beat that! Took him about 3 hours to cobble up. must be time for another dodgy day soon....

ive done a similar intake on my nb8a.

dont need to extend wires on the 8A just have to seperate the ones you need from the jumble of wires heading to the other side of the motor.

i used dunny pipe to make an air ram from the front bar to an alloy checker plate air box then had an open fillter and pvc elbow much like bevans.

i have since made a new elbow and used a matt black colour rather than the dodgy wrinkle paint thats in that picture and have a stainless fitting for the valve cover breather line. not sure if its just from my driving but i do find the elbow tends to warp from heat after awhile and can come loose.. im looking into other materials for the elbow. but for now i just replace it when it gets too bad.. only had to once so far.. and its been on there awhile now... maybe a year or so???

theres some dyno sheets at my car domain site, but i have also replaced my exhaust system.. so no direct comparisons on the returns of just the CAI. however i do believe it makes a bigger difference than the headers.

went from 73 to 83 rwkw with full exhaust system and CAI though i did post a 91rwkw at mania but their dyno had recently had new hardware installed so... cant believe that one..

this biggest gain is in throttle response if you jab the throttle you can hear the motor gasp in air, and it works really well at high revs and speeds. it also can get a tad noisy with the stainless mesh filter i have... sounds super charged :lol:

but im very happy with the way it goes and sounds...

have you done any other mods to the car?? would be interesting to hear it with a standard exhaust as ive heard people say a CAI can make the car sound as though it has a mild exhaust mod
