will it work with a stock LT1 hood? i want to do this but dont know if it will all fit. thanks

 

No, there's not enough room under the hood for the airbox.

 

It would also be a big waste of money. A regular CAI would provide much better results

 

I'm gonna have to disagree with you on that one. A straight-in design would be alot better than the (2) 90 degree bends in a regular CAI.

 

The only straight in design you're gonna find for an LT1 would be any of the firebird ram air hoods, or the SLP Ultra Z hood I believe it is for the camaro. Even that's been debated as to whether or not it's better than the CAI.

With the Ram Air, you're getting the straight in shot, but what if it's hot air? Also, with the Ram Air, you're not really getting the "Ram Air" effect as advertised until at least 80 mph. It's more of a direct air system.

With the cold air, you definitely get the cooler air from the fender area, but you have to subject said air to a couple of bends.

There's plusses and minuses with both systems, but either way you look at, it's better than stock!

 

Yea, what I was saying is to convert the entire radiator shroud as well to the LS1 style. Otherwise there wouldn't be much point unless you have a Ultra Z hood.

 

Those Ram-Air-Boxes aren't straight through, atleast not the ones I saw. They are that box and then they make an easy 180 into the elbow.

 

Well, iv thougth about it and your probably right when you say you get colder air from a CAI. But what about the bends in the CAI and the amount of distance it has to travle before it enters the intake? It would seem since with the CAI it has to travle more of a distance to get to the intake that it's exposed longer to under hood temps then with the ram air induction. Pluse dosen't it seem that you'll get better air velocity with a ram air induction do to it's straighter flow of air then with the bends of the CAI? I think either way you go there is very little differance in preformance between the two. But if you'r running in the 1/4 and the ram air effect doesn't kick in untill about 80mph then it still leaves over 20+mph left of accereation on the table to benifit from the ramair set up befor the 1/4th is over, seeing how we usally trap any where from 100mph to 115mph on stock motors. I think you'll see better gains with ram air in the 1/4th over CAI. But then equal gains vs. the two in the 1/8th

 

A 180º huh? That must be a nice bend

 

That's on the Camaro hoods. Look at the Trans Am hoods. Once you cut out the baffles, you can look directly through the hood into the throttlebody, provided you take out the filter.

 

a Cold Air Intake or CAI doesnt funnel in cold air. its only cooler air relative to the stock air box so a CAI doesnt actually cool the air.. its the same temp as whats outside. i am sure the same applies to ram air setups.

I too have to agree that the ram air designs on the WS6 and alike hoods that its the best induction system you can get. not only does it actually function as a ram air but its a straight shot into the intake with a distance of less than a foot i believe. the surface area of those WS6 air boxes is also about twice that of the SS air box and probably close to that of the filters put on CAI kits.

 

Defeine Ram air effect.
In order for a scoop to begin pressurizing air the vehicle would have to be going well over 200 MPH.
In fact I recall a very consistant 7 second dragster after running his dial in several times turned his scoop around to prove apoint and ran the ecaxt same time. Think about this. every time a cylander draws air in it draws in air from the intake plenum and intake runner. there is ample time for the plenum to refill at anything short of 9k RPM on a large dispasement engine provided the throttle blades are open. My point is. Those bends in the CAI are so far back in the system that they do nothing to effect air velocity or flow volume by the time you reach the runner. CAIs help because they draw in cooler air. not because of better flow. Mabye at 10 or 12 RPMS a CAI would begin to become a restriction. But I dont think any of use have to worry about that.
A RAM-Air system is the same as an effective CAI. If anything, the only reason it helps at higher speeds is not because it pressurizes or flows better air, but because it removes air in-front of the vehicle createing a lower pressure area there that is easier to push through.

 

the best setup is a Ultra Z hood or a WS6 hood with a LS1 K&N FIPK and a radiator shroud cut underneath.

Yeah ALL of the SS hoods are a complete JOKE.

 

Where are you getting this stuff about 200MPH and 80MPH? "Ram air" isn't something that turns on at certain speeds. The problem is that its effectiveness varies with the "square" of the speed. Go twice as fast, and you get 4X the "ram air" effect.

The pressure gain available through ram air can be calculated using the concept of "velocity head"... and with some crude calculations, it can be demonstrated that at 100MPH, you could gain abour 1%.... or only 3HP in a fairly stock engine. Cut the speed to 50MPH, and the gain drops to 0.75HP. Increase your speed to 150MPH, and that 3HP becomes about 7HP.

Also not sure why most people think a CAI is supplying colder air than a scoop mounted at the leading edge of the hood. At best, they are both pulling air from the same source, so the temp will be equal. At worst, you will be seeing some air temp increase under the car, when hot sun runs the asphalt temperature up to 130-140degF.

The WS6 or SLP Ultra-Z hoods are not very free-flowing, as received. The double baffles force the air to bend down under the front baffle, to throw any water out and through the drain holes, and then bend 180deg up and over the rear baffle. Removal of the baffles completely leaves a fairly irregular flow path, and allows substantial amounts of water to flow through. I have both baffles completely removed, and when I tow my car, I stuff the scoop with foam rubber to prevent water from getting into the filter.

I think the main advantage of the "ram air" type setup (and I don't think even Chevy ever claimed "ram air" capabilities for the pretzel shaped SS setup), woudl be the shorter path with less bends. I don't think it can get any straighter than this.
