Vararam Industries LNF Intake Update....
. I got it to a point where i've rotated the filter in such a way that I get negative stft's on cruising and when I go full throttle it goes to 0.0 and stays at 0.0. At idle, its -0.7 to 0.7. The K&N intake has a offset fiter, I discovered rotating the filter changes the fuel trims.I know that sounds crazy but I gotta get a video of this I guess.

Patrick @ Vararam Industries: LNF Intake update.
I spoke with Patrick yesderday evening and got an ear full in reguards to the research that is going into this intake. From our conversation, this intake is hands down going to be the most advanced, well though out intake on the market today. From plenum boxes to multiple air straightners and the ability to support 600+ hp, this intake is going to be worth the wait. Other features will include ram air functionality and an air cooling effect that will cool the intake air temps lower than ambient air temp. He has been working with the Duramax and Camaro V6/V8 engines recently and has learned a bunch in reguards to how the MAF sensors act under certain conditions and will be adapting several tricks learned from these applications to the Cobalt. Particular attention has been focused on MAF screens of different thicknesses, materials, and cell sizes in hope of keeping the MAF happy during partial as well as full throttle acceleration. Actual assemble of the first prototype is scheduled for next week and he is excited about it in the sense this has proven to be one of the most challenging intakes to build yet.

do they have a eta for this? end of the year or fall?

Yeah, I too am eager to see pics and hear more about it's design and expected timeframe. This is one of the last mods I've been waiting on to do, and I'm getting antsy... especially if this particular product ends up being as good as it sounds.

why would we ever need any air cooling effect on the intake?
its going to go into the turbo and heat up.
we need to focus on more intercooling. as far as the intake, hopefull this will be a good alternatives for those that don't want their trims skewed by the maf change.
i heard some positive things about the new design from the new k&n intake so it may have some comp. either way i decided so say screw it, and relocate my maf to the cold side that way my hanh intake isn't an issue, neither will a bov later on down the road
I like all the features on this intake. The cooling lower than ambient is kinda fuzzy to me since the intercooler is never going to be cooler than ambient so the air entering the intake mani will only be as cool as the intercooler can get it. I may be wrong.
Im sure that the cooling effect is just a by-product of some of the other great features of this intake.
Cant wait!

With a lower intake temp, the air coming out of the compressor will be slightly cooler. As no air-air intercooler is 100% efficient (removing all the added heat from the compressor), the cooler inlet temperature of the air entering the intercooler is likely to result in a cooler outlet temperature as well. This is probably a very small change in temperature though, given the nature of the cooling effect.
They are saying there is an air cooling effect present in the intake before the compressor that reduces the pre-compressor air to below ambient temperature (from my understanding)

As it is, my IAT2s (post-intercooler air temps) are cooler than my IAT1 (air going in the intake) during normal driving. My Hahn is already sucking it up for the intake temps already, so not that worried about a few more degrees. I've got an idea to help with that too though.
