early xmas for the c32 crowd!!
now dont go thinkin you will be able to best the slk32! this may help you guys get close though!
if any of you know about needswings you know rob has top quality mods with all the data to back them up. cheap they arent but worth every penny! merry christmas!out of curiosity, any ballpark numbers over stock or other style intakes?
also....for those of the c32 guys who are basically maxed out (185 pulley, headers, tune, intake, heat exchanger, etc), i would imagine there would be only a minimal increase in power (if any) since we're already at the fuel limit. can anyone confirm or deny (or simply reply to?) that thought?

It's kind of plain looking, but very functional and top quality work.
One may be coming my way soon.

please keep us posted on your findings (assuming you are getting the intake)

Worst case, I'll get myself an SLK fuel tank with an SL55 pump.

And a lil reference thread to go along with it...

we have previously tested several combo's of our CAI/DCAI's along with the stock srt6 intake system, that data is here...
http://www.crossfireforum.org/forum/...flow-data.html
todays testing was also done at ~ 15in/h2o
the sl55 setup we recieved had some trimming/damage to one of the "snorkle" tubes in which i assume he trimmed to fit on the srt6. we did however had a brand new identical (without the trimming done) air snorkel tube here that we did up for a sl600 a while back, anyways i substituted that in place so that both snorkle tubes would be OEM sl55 so the trimmed/broken inlet end would not squew the results. the sl55 setup had paper filters installed (not k&n drop in's) so thats what we did the testing with.
the results were what i was expecting and saying for the past few years but today i ponied up and dropped some coin for the flow bench time so this could be put to rest.
stock sl55 setup with paper filters and stock snorkle tubes flowed between 513-515cfm @ 15 in/h20
i then went for the devil horns setup. now i do not have any of the aluminum tubes that customers have been using to connect the devil horns to the sl55 airboxes so i did make a substitution. the tubes anthony sells have 2 bends in them, the tube i substituted had only 1 bend in it. sorry i made due with what we had here today. to once the substitued snorkle tubes went on we connected up our devil horns. with the horns on and the same flow rate we made 529-533cfm.
the attachment to the flow bench was identical to the setup we used on our previous trip there with the straight 3" tube heading up and then a 90deg silicone coupler to another straight section of 3' tubing aiming towards the back of the bench, this enabled us to attach the entire intake systems. yes the number for all tests would have been increased if that setup was not used for the adaptor to the bench but at that point we wouldnt have been able to test most of these setups. the important point is that all tests were performed the same in a climate controlled environment even though they were done on different days. im sure there is a very slight difference in humidity from then to now but we are talking a very slight difference in numbers if any.
so there is the data, the sl55 setup does indeed flow better then the oem srt6 air intake system but it is no where near the flow numbers of even our single CAI system.
so to get the important numbers together...
stock srt6 intake = 446cfm
sl55 intake = 514
sl55 with devil horns = 531
single CAI with teflon = 602
dual CAI with teflon and big filters = 748

just in case some one you know has a e55 he is the pic of what it will look like.
I will have some 1/4 mile times before and after soon.
of both my car and a friend's e55 jim

Really looking foward to the results!
