Ram air...HP and problems?

hey i have a 94 TA and for this xmas season i wanna get a ws6 stlye ram air hood for it. I was also kinda interested in VFN's 4inch ram air cowl hood. Either way i have heard about people having problems with any ram air hood hyrdolocking their motor bec water goes through the nostrils and into the air filter. Does any one know of this being true for sure, and wouldn;t it be worse on the vfn hood? Also i was looking at suncoast creations hoods and saw 20-25 rwhp gaurunteed. I even called a rep from there and he agreed, bec of the size of the filter and box and he said i would gain at least 20 with stock exhaust manifolds and everything else stock. I then asked how would it be with their pizza box of an airfilter box on a different hood, and they said it wont work on a different hood. Does any one know why this is, if its even true, and has ne one had experience with making a glasstek hood functional? Another thing i have heard from a lot of ppl is that most CAI kits these days for the lt1s make more hp than the stock ram airbox. I wanna hear ur guys opinions and facts if u know ne thing or expereinced this stuff first hand.

From what I have read many people prefer the CAI kits over the ram-air.

Re: Ram air...HP and problems?

Do a search man, firebird ram air hoods (like the ws6) with airbox are comparable to a CAI. As far as XXX MFG's claims of 20hp gains with a ram-air hood? No.

And Hydrolocking is not really an issue, do you think GM could get away with releasing hundreds of thousands of WS6 cars with the potential to ruin engines when it rains?

Re: Ram air...HP and problems?

I agree, hydro locking is not anything to worry about. If you look at the design, almost all water is not even able to get to the filter...

Thats with the Camaro's, and their more restrictive "Ram air" (not really) SS hoods.....

Re: Ram air...HP and problems?

if you put the suncoast intake on a non-ram air hood, you would choke your motor! (not sure if that was what you were talking about) But, I am not sure if the box would work with a different hood.

Re: Ram air...HP and problems?

get the hood for looks

keep your CAI

you won't see enough of a gain switching from the CAI to the ram air to warrent the cost, even if you can sell you CAI later.

maybe in situations above 100mph the ram air would start to show a benefit, but around town not much.

and of course the tech guy at the company is gonna agree with the "claimed" 20-25hp from the hood...he wants to sell his product.

Re: Ram air...HP and problems?

I went from a CAI to a Ram Air Set-up. I bought a non functional hood, and cut everyting out myself. So there is nothing between the scoops and the filter. No pieces to help block the rain. I have had no problems with it in the rain, or even when I was my car. I also could not tell any difference power wise between the two of them.

Re: Ram air...HP and problems?

Hydrolocking from the hood... ROTFLMFAO.... yea...

I've got all the rain baffles cut out of my hood, and even driving in the rain there are no issues (Although I do not recommend this at all).

As for CAI Vs WS6 RA setup... it's been argued over and over and over again, and for the price it's not worth it to most... but from an engineers standpoint the WS6 RA setup is the best CAI you can get, hands down.

*Note: if anyone wants to argue that fact again, I'd love to see someone with an actual Engineering degree (Other than myself) who knows fluid mechanics explain how they are equal by any means.

Re: Ram air...HP and problems?

we need an "im with stupid" smilie!!!!!! because I agree with ^. It IS the ultimate cold air intake! Think about it... the air coming in is about 2-3 feet above the hot tar. Where do you think the air is the hottest? AT THE TAR. So, that cold air intake is sucking up hot air. Granted, its better than hot engine compartment air, but still. 3 feet above the surface is much cooler, plus the wind has had a chance to bring the really hot air off the tar by that height. With all that said, ram air is the best route for a firebird. But~its extremely expensive.
Basically, if you want it, scour the junkyards! I got almost everything from there, for about 10 percent of what the dealership charges. The only thing I had to buy from the dealership was the box bottom, and that way 136 my employee cost! Just shop around, otherwise you will spend a boat-load!

Re: Ram air...HP and problems?

As far as performance gains, I do not think there are any. I remember reading something saying GM did not actually see any horsepower gains from the ram air or SS hood until they reached speeds of 110, or around there, or higher. A lot of people hardly reach 110 before they are at the end of the quarter mile.

Maybe if a http://www.turbonator.com/ is installed you can get lower MPH gains.
Ram air+turbonator=

If I install one of these in my exhaust pipe, I wonder if I will need a blow-off valve.
LMAO

i would also like to know if a suncoast box would work with a different hood. I bought a ram air box and they guy i bought it from said it was a factory box and when i got it, it was a suncoast box and i just ordered a SLP hood so i hope they work together.
