Are Ram-Air Systems Worth the $$$? I'm considering purchasing a ram air system for my car, most likely the SSRA, but I've read that these kind of systems don't make a lot of improvement. Is this true? Do any of you have any before and after dynos?
Thanks,
Josh

Re: Are Ram-Air Systems Worth the $$$? The improvements show when the car is moving at least 30-40mph. It really won't show on the dyno if thats what you are asking. 
I would rather get the FTRA myself.

Re: Are Ram-Air Systems Worth the $$$? I disagree with ram air kits not showing up on a dyno. Stock my car made 299.9rwhp. I then put on the Super Sucker Ram Air. I put a construction fan/blower right in front of the scoop. We did this numerous times. The best increase was 13rwhp, with the average 12rwhp.

Re: Are Ram-Air Systems Worth the $$$? im getting the ftra this week but i dought i get to run just that this weekend because im planning on putting my cam and stall in this weekend but ill see how all that goes. i ran 13.2 one week, then took out my filter, jack and tire, and still ran 13.2? so i didnt see anything without the filter!
Re: Are Ram-Air Systems Worth the $$$? Big difference from lowering IAT on these cars,
both from the cooler air itself and the PCM's
response to it. There may be minor pressurization
effects but these have never been quantified to my
knowledge (ETs maybe but no direct before-throttle
PSI numbers).
Various ram air mods have different effects on
IAT; I notice that a FRA-like setup (I hacked up
an SLP CAI piece to draw from the nose area) has
a higher IAT than my SS hood alone, under low
speed conditions. Under-car air is pavement temp
at worst, and Florida pavement is slightly warm.

Re: Are Ram-Air Systems Worth the $$$? Is there any problems with having water getting in it when it rains out. Does it get inside and everything else. I know the mustang ram air would suck water in on the fox bodies. Wasn't sure about this one.

Re: Are Ram-Air Systems Worth the $$$? when we had that bad rain these last couple of weeks in nebraska i drove my camaro in it even through a couple big puddles and i have the ssra. my suggestion if you happen to go through something like that go very slow and you should be fine.
Re: Are Ram-Air Systems Worth the $$$? Ive been thinking about the supersucker ram air too, but the water suckin is what im kinda worried about. I think ill do it and put in a blocker of some sort to keep the water out in the rain. Harwood makes all those scoop plugs, they cant be too hard to make. a lil fiberglass in the house : ) Ive read 15 rwhp at 60 mph. This was done on the dyno with a huge fan in front and something measuring wind speed at 60 mph, and a 15rwhp gain. not too bad for 200 bucks...cheers to the ls1!
