Forced Air

Water injection is still used...

From Kennedy's Dynotune:

History of Water Injection

Water injection isn't new technology. It was used in WWII to help performance on supercharged fighter aircraft. We have applied the same principles used successfully in WWII to the modern automobile. Kennedy's Dynotune has taken an old idea combined with technology and achieved impressive results. As an example, one of our customer cars is a street/strip LT1 Camaro that makes over 700rwhp with water injection and without an intercooler.

That's just one of the places that specialize in water injection.

Don't shoot the messenger

Skant, I'm just reporting what I saw happen. It was a real shame being in BG and all. The air dam is 4 inches off the ground, and if you have a cut shroud Vortex and hit 6 inches of water it goes into the intake.

The diffuser intake is 16 inches. You could find water that deep easily. The intakes on most cars ingesting water is a non issue. Of course you can drown any vehicle. I think ram air is a waste of time anyway, but it opens up catastophic possibilities, however improbable it may seem to you.

I have dripped water into carbs many times to burn carbon. But gulping a gallon will kill an engine at moderate revs. As stated before most modifications carry potential consequences. A supercharger or nitrous can blow your engine etc. etc.

Still friends?

I'm not upset. I hope you aren't. If I sounded angry, I certainly didn't mean to. I apologize if that is the case!

I just happen to think that driving any corvette in any conditions where you would run it through 6 inches of water is not a good idea. There are several other components besides the air intake that will be damaged by being drenched or submerged in water in a car with only 4 inches of ground clearance.

So I agree that the lower intake makes the car even more vulnerable under such conditions. But I point out that the car is already going to get wrecked by water that deep for other reasons.

If someone does drive a corvette in conditions like that, well... then I'd certainly avoid getting any sort of lower intake in the car. But I also question the wisdom of driving this kind of car in those conditions at all.

Just to repeat... I'm not angry. I hope I'm not making you angry. I'm just expressing my opinion. I'm smiling right now. Really!

Sorry, but a brief hijack is in order I think. I tried to either PM you, or send an e-mail Skant, but you don't allow it, so I gotta do it here.

I'm not upset. I hope you aren't. If I sounded angry, I certainly didn't mean to. I apologize if that is the case!

After seeing such a polite exchange here, it caused me to wonder abiut a comment I made in your "rear gears" thread, about your choice of "Skant" as your moniker here at the . I hope I didn't upset you with that comment, I certainly didn't mean to. And as you say, I'm smiling right now.

Air Dam

Tlong, The air dam for the radiator is 4" off the ground, what the debate is here is abut the license plate area being used for the air duct which is about 14" above the ground.

Getting caught in a bad thunderstorm and flooded roads at night on a very dark country road has nothing to do with a person being wise or not. This is a bad combination, especially if the person driving does not know the roads. Most people can't see the large puddles on back country roads, it's way to dark.

 

[garycr14]

Rain drops keep falling on my....

Well Steve, I will have to agree with you, if you live someplace where it rains a lot, and drive on dark country roads, and there tends to be a lot of puddles that are a foot or more deep, then you probably wouldn't want to consider this upgrade. Manassas falls into this catagory, at least outside of the town. But for the rest of us, this is a cheap way to get an increase in horsepower without having to give up much in the way of fuel economy. I try to avoid driving mine in the rain, although it's not a garage or trailor queen, and I have got caught in the rain. Just hate cleanning it afterwards, the dirt finds its way to the smallest corners of the engime compartment.

 

[Grizzly]

Well folks I had a 77 Jeep Cherokee with a hose running from the grill area to the carb to give it cool air (stock item) and it would flood out in a bad rain storm. That pipe was more than three feet off the ground. After the second time I took it off.

I installed the "forced-air" on my 92 and it looks great.You can definately hear the sucking sounds and if you don't drive it in the rain(like I don't) I don't think you will have a problem.I had it professionally installed.The mechanic told me that it wouldn't make that much of a difference in power because I didn't change the throttle-body or any other intake parts.I mean he said it couldn't hurt......I did it for the "look" really.Some mustangs take one look at it and just idle away....It's intimidating to them.....:L ......I can't wait to take it out for the summer......I hope I can eventually learn how to post a pic or 2 on this site:cry

 

[mattyg92]

if you could post a picture of it or send me one that would be great!

Oh no, that didn't upset me at all. In fact, I have the same problem with the Skant name. All of the misreadings of it are bad things. And there's even a cut of modern blue jeans that uses this name now, too. Bleah.

Basically, "Skant" was supposed to be a temporary character the first time I got onto an internet MU* system... figuring that I'd mess up my first character. But instead, I became rather well known with this name. So I've been stuck with it forever. Most of my friends know me by this alias. It was just a random syllable off the top of my head. It's not supposed to mean anything. It was supposed to be unique and temporary.

Ah well. It's my minor curse.

As long as I'm interrupting this thread... let me toss in that I really like these rather flame free forums. Corvette owners are a good bunch in general. And Ken and crew have done a good job keeping it all nice and friendly.

Okay... enough off-topic... we now return you to corvette discussion...

Ill open myself up for a bunch of crap here BUT,Has anyone (other than the manafacturer) ever done a REAL test of some of this JUNK!!! Now,IMHO if you were going out on the salt flats,and were going 100mph or faster at WIDE OPEN THROTTLE you MIGHT be able to record a difference. Any airflow getting into the engine still has to go through the throttle body, and as small as the T.B. openings are, the ONLY way to force feed it air is with a BLOWER or TURBO!!!!! Dont believe me? Put a pressure guage into the intake manifold,Ill bet my last buck it will show 0 psi. and 0 psi is 0 added power DUE TO FORCED INDUCTION, And thats ONLY at WIDE OPEN THROTTLE!!!!!! IMHO not a good investment for a street driven Vette!! Save another $3000. and put a blower on it, THATS BANG FOR THE BUCK!!!!!!

Just to make sure where on the same page here(so to speak).I was-am talking about a C-4, Which has a fairly good (but somewhat restrictive) Cold air intake system rite from the general. The air filter housing mounted in front of the radiator and just above the airdam is near perfect!!!!! Nice cool air (not under hood temp) And fed from the airdam. Now add a Quality air filter and modify the filter lid and for 50 bucks your GOLDEN!!!!! Same temp air as the ram air system and same Volume of air. I still dont think ANYONE can show a positive pressure inside the intake manifold, and without PRESSURE, NO H.P. GAIN. Sorry but thats my story and im sticking to it.

Ram Air

On a C4, at least on my LT1, the air dam below the front bumper only draws air up and into the radiator, and sends the air behind the the air cleaner, not into it. The air cleaner draws air from the front of the engine compartment, warm air. The Forced Air system that is being discussed here is through the license plate housing area, and draws cold air from outside the engine compartment. Another factor to consider is the system is designed by it's angled shape, to compress, and force air into the engine. If you don't think this can work, then you can't believe a supercharger will work. A supercharger forces air into the engine, and will improve performance evan without opening up the intake system. These systems work. You can feel the power especially at higher speeds. I have one, and I'll be glad to match up against another LT1 or LT4 without one at the drag strip. You might want to drive a care with one installed before you discount their value.

Well I just got my kit and I cant wait to install it!!


Garycr14, was it hard to do? do you need that 5 1/4" drill bit like the instructions say?
do you have any tips from doing it?
thanks

Tools

It was not really that hard to install. Mostly my nerves got in the way because I didn't feel good about cutting a hole in my baby. I didn't use a 5 1/2 in bit, I drilled a few pilot at the corners of a rectangle the size of the opening I needed, then drilled a buch of holes to between them. Then with a hack saw, the kind with a blade and a small handle, and connected the dots so to speak. It's just fiberglass and syrafoam in there. Went fairly fast. The difficult part was cutting the crossmember which is part of the bumper. I did that with a Saw's All. I haven't had the cross member rewelded back together as of yet, but I think I should. You'll see it as you go. I didn't have instructions as I bought mine used, got lucky and found a used Torch Red one that someone didn't want. Matches my paint perfectly.

Good luck! You'll feel the difference.

Matty.....I'm sorry if I didn't post a pic of my ram-air for you on this site.The reason is that apparently my pictures are too "big".I could e-mail them to you but I can't seem to find your address.Like I mentioned before, I had mine professionally installed and painted.It looks great and I "feel" a difference.I didn't do a 1/4 mile test before so I can't give you any concrete evidence.I hope you can do a before and after test.....it would give the non-believers a little info :argue ....I did it mainly for the look but my mechanic JPL PERFORMANCE told me it would help at higher speeds.......I'm sure you'll like it.....I do !!!
