Cooler Air Induction on an L Series (Snorkel)
Posted: Tue Jan 30, 2007 4:37 pm
So what does Jaffa do when its 40+ degrees and its decided that it is to hot to go 4WD... you attempt to kill 2 issues at once, 1) Attempt to find some cooler air for the engine and 2) prepare for the wet seasons numerous water crossings of course.
This is not the most elegant thing I have ever made however its not PVC and so far its working. Actually I am not sure that the pictures does it justice, it will be interesting to see if it remains as well – I am not about looks (com'n I 4WD in Pugs) but for a first draft/attempt at a working model at this stage i am ok with it.
As we know these things are scarce for a Subaru and i wanted 1 with as few bends as possible, hence it not going into the panel closer to the door, with this design i have also been able to retain the original air box set up. The other bonus was that this was WAY cheaper then the factory thing.
What it has done is increased the impressive induction noise as you can now hear the turbo spooling up in the snorkel pipe and the air being rammed/sucked in - hmmm impressive induction noise, well for an EA82T it is ;-)tehe
This has so far proven to be noticeable but not invasive, and i took it for a drive in some monsoonal rain we had here the other night and it appeared to drink very minimal amount water (like about half a tea spoon) and there is a small 6mm drainage hole in the bottom of the air box and the small amount of water was heading it that direction anyway.
As you can see from the pic's it could be better but and could possibly do with some minor tweaks, so i will see. If other have some feedback (positive or negative) and/or suggestions i am open to hearing it - i have only posted on here at Subarino's request (and thanks for hosting the pics Dave)
As for performance, like Subarino, i have not noticed a huge spike in power (nor would i have expected to) however it has increased a little bit for us as i have a 3" pipe feeding air (to an original air filter and not an after market unit) as apposed to a little piece of plastic picking up air on the inside of the guard. In addition to this i also know its clean cooler air.
Now all we have to do Subarino is find some deep puddles (and maybe move our stereo gear off the floor).
Note - I would also like to thank those members that were willing to discuss some of these issue with me.
