I am looking to purchase a cold air induction system for my C6. I hear the Vortex or the lingenfelter are the ones to buy. Does anyone know which cold air induction is the best for the C6?
Thanks
Rick

 

Do you think 10-15 hp will be noticeable on a 400 hp car?

 

The one that doesn't risk WATER INDUCTION into the intake. All of the systems that put the airbox on the fan shroud run this risk. While some of the manufacturers have gone as far as to state that their systems have "minimal risk", NONE will state that there is no risk - not do they warrant against it.

ALL have the systems generate very similar horsepower gains on a dyno - the advantages of putting ambient outside air into the intake are only seen when MOVING.

That being said...

The Halltech Stinger & Halltech CAI are (though my research and in my opinion) the ONLY one's that don't put the motor at risk. The Halltech CAI mods a stock piece under the radiator to allow cool air into the engine compartment. While it doesn't directly duct air INTO the intake, you get the added benefit of increasing airflow through the engine compartment, and it's proven to put ambient temp airflow across the filter element. The opening it creates is on the bottom/sides of the fan shroud, in such a way that you'd have to submerge the grill area at speed to drive water far enough up into the engine compartment to risk ingestion. While I'm not going out to test it, you'd have to drive through a foot deep puddle, real fast - and even at that, it's still unlikely you'd suck any water into the filter element.

In contrast - the other "bottom feeder style" intakes would actually DIRECT WATER INTO the filter element, by thier design - and this would only require hitting a puddle fast enough (and shallow enough) to drive wake from the wheels into the fan shroud.

I do enough things to put my car at risk (like driving real fast) without buying aftermarket bolt-ons that add to that risk.

I am NOT an employee of Halltech, just a satisfied customer. Shame on the other vendors who have side-stepped the "water ingestion issue" and continue to put thier customers engines at risk.

 

Rick is definately entitled to his opinion, after all, it's his car.

There is a risk of ingesting water into your engine with any type of car.
Don't believe me? my mother ingested water in her 1990 Buick skylark before it was fashionable to do so

The point I'm trying to make is, you can ingest water if you try hard enough, no matter what you have on your engine. If your that concerned, and think you might be at too big of a risk, then don't buy one.
But don't be sucked into the belief that putting an LPE designed part on your car will ruin your engine because it's just not the case.

Feel free to let me know if I can answer any questions for you,
Ed

 

Sorry you felt impuned Ed. I never implied that LPE or any of the other manufacturers INTENTIONALLY designed/sold products that were designed to ruin your engine.

Just that none has ever discussed what methods were incorporated in their designs to MINIMIZE the increased risk that "bottom breather" type intakes impose by their very nature. When asked about this, numerous vendors simply side-stepped the issue, or never answered the question at all. If anyone sold a bottom breather system that included some means to offset the greater risk of this type design, I would very likely have considered it for my own C6.

Due to the similar gains of ALL the intakes designs, I simply suggest that the one which pulls air from lower, and has the added benefit of cooling the entire engine compartment (and not just intake air) would be the better (or best IMHO choice). FYI - the Halltech is actually a very simple (and very inexpensive) DIY mod for those that aren't as LAZY as me. Jim just thought of it first.

That being said, Ligenfelter has a sterling reputation in the Corvette aftermarket, and I doubt would design/vend anything that would intentionally harm a customers car...

The LPE intake seems to put up the best numbers for a bottom breather. Though it does run the slight risk of water ingestion.

I personally like the haltech stinger + CAI option. However, the CAI shroud is a PITA to install

 

10-15 here - 10-15 there - before you know it you're in C6 Z06 territory But the best HP to weight gain for me is to loose a few doughnut related lbs.

No hard data to my knowledge.

Vortex - HalTech - Honker

I went with the Calloway Honker cuz

Just logged on before I'm out for the evening. The Lingenfelter High Flow System is by my estimation the best on the market to date. I just don’t buy anything without thorough investigation.
The largest air filter, Smoothest transition from filter to throttle body, OE look and fit. After I installed this unit I took a run on the interstate. While out about 15 miles from home it started to pour buckets. I was running at 70 mph for 10 miles and 35 - 45 mph the rest of the way all-the-while it was still raining. When I pulled into the garage I was worried about water and popped the hood to check on everything. Besides a little wetness at near ground level there was no detectable water near the filter. I have this dampness probe used to detect moisture in wood and other materials and the meter read only 3.6 on a scale of 15 (15 = soaked). Acceptable reading for just a humid day. I don't know Ed or Lingenfelter any other way than this one order; but I will tell you that they are one of the very few merchants I've dealt with buying Corvette supplies (Zaino was the other) that has lived up to my expectations. I cannot believe anyone would regret purchasing this HFS from Lingenfelter.

 

Great post - we need more of this then some others!
[B]Geez OMG! Too much!

 

Perhaps one of my daughters will suite you mo betta

IMO the water ingestion fears from the current aftermarket high flow intakes are overblown.

most of the aftermmarket intakes I've seen are either a large filters sitting behind the shroud (Halltech, Blackwing, etc.) or a box at the top of the shroud (Lingenfelter, Callaway, Vortec, etc).

each of the setups use a high flow filter.

the units that use just a large filter all have a downward pointing filter. any rain that would enter the engine compartment will continue to flow down toward the ground and not be sucked into the engine. the water is not captured or retained or allowed to collect enough to be sucked into the engine.

the units that open up the shroud and use a box at the top of the shroud will not capture enough water to cause the engine to ingest water. these systems use a downward facing box. gravity helps these systems. water that enters the engine compartment from the top (hood) will pass by the box and fall towards the ground. water that would be pushed upwards toward the filter will not collect in sufficeint amount to be ingested into the engine, the filter will actually stop any water mist from entering. the filter may get wet but anything that passes through will be mist and not harm the engine, it may actually help clean it, but that's another post.

in order to ingest enough water to harm the engine from any of these systems you would need to drive though deep standing water. driving through deep standing water will cause any engine (save for the hummer ;-) ) to ingest water regardless of filter setup.

the only filter setup that is currently ava. on the c6 that will and does collect enough water to permit water ingestion is the modified stock setup. if you remove the rain guard the stock air boxes will collect water, the filters will get soaked and water will pass into the airboxes and collect in sufficient amount to actually fill them, causing the engine to suck in water. notice the difference with the setups. the modified stock setup has aircans or boxes that open upward and permit capture/collection of water while the aftermarket intakes has downward facing boxes that will not collect water, due to gravity.

 

Interesting though, West Coast Corvettes comments on their intake:

I don't think anyone has said "put a bottom breather on, and blow your motor". The object of the fan shroud is to direct/force air through the radiator, condensor & oil/tranny cooler. By placing your air intake in this path, one attempts to take advantage of this "directed" flow. Unfortunately, this also includes any moisture. It's likely a very rare occurance when enough water will be directed into the intake area for ingestion to occur. The main point that I (and others) are trying to make, is simply that of increased risk of this possibility. So far, the WCC site is the only one that even addresses this issue (though I'm sure many of us would like to know just how this was accomplished). Many of us try to minimize our rain driving, so this becomes less of an potential issue. My C6 is my daily driver, and I live in the land of daily rain - so this was a greater concern for me - thus I went with the Halltech Stinger/CAI - which I believe delivers a similar ambient temp. airflow, at less risk for potential ingestion.

My point(s) are not meant to scare anyone (or cry wolf). Many folks comment on these "what is best" type threads, without stating the justification(s) for their opinion.

understood...

I just wanted to make the counterpoint. In the end I (and I assume so do you - at least that's the impression I get) feel it's up the the individual to decide if they want to make any mod. which, by the way, can give the general reason to deny warantee work. It might not be right and legally they have to prove that the mod. caused the issue but most of the time it's more difficult for an individual to fight the dealer than it is to just pay for the repair.

 

Be careful when you defend a position. I've had hydoloc which cost me 11.5K and change.
Conditions:
less than 5mph
less than 3" of water in puddle
traffic behind me
no where to go
water wake from front wheels caused water to hit filter
two rods broken
two corresponding holes in block
Have docs to prove if you still doubt along with video of blowen motor

 

Buy a supercharger,you'll get all the air and h.p you need!

 

how much $$$ are superchargers going for ? and whats the best type. thanks mike
