cold air intake Sun, 13 March 2005 08:54 Go to next message
i've been reading/thinking a fair bit on this subjet lately.
found an interesting article here...
http://www.autospeed.com/cms/A_1023/article.html?p opularArticle

my plan now is to have a filter box like this off my twin carbies
http://img168.exs.cx/img168/4290/filterbox8jx.jpg
from that, run flexible pipe to a custom enclosed filter housing made of alluminium/stainless steel with a pod in it, located in the front drivers side of engine bay
(i'll have to move overflow and washer bottle for this)
from the bottom of this filter box, run a 2-3 inch pipe thorough the wheel arch Twisted Evil (cutting holes in my body is always an option with a t-18) and out to the front of the car just under my bumper?

ive only seen this done on one other car before and am not sure if its a good idea, only reason i can think so is that it might take too much dirt in.
so i thought if using PVC for the intake, just get a cap for the end of it i can leavin in the glove box to wack on the front for those dusty times Very Happy

so basically just wondering what everyone thinks of this intake feed to the front of the car, and what everyone else is using for intake?

They are a good idea, but is the surface area of the inlet to your filter box larger than the combined surface areas of the carby throats?

ie. will it be a restriction?

x4 40mm carbie throats, so the size of my intake pipeing thoroughout the hole system would need a diamater of 80mm or more?


i worked that out the hard way i think-
pie x radius squared x4 = 5, 000.548246 mm squared
/ pie = 1600
square root = 40
x2 = 80 Confused


thats not very big at all
would there be any gains by having the pipe any bigger than this?
