Re: 96 SS LT1 Air filter
you def hear a difference at speed and higher rpm then just rpm.
why does this even matter stock op temps are so high on the motor that I don't think air has a chance to stay cool all the way to the combustion chamber.

Re: 96 SS LT1 Air filter
LOL @ the 90 deg bends.
Don't most CAI's on the market have 90 deg bends in them? Isn't the tube between the MAF and the TB a tight 90 deg bend?
I run the ram air hood on my 94 T/A with a stock ram air airbox. Before that I had the SLP CAI. People told me there would be a significant difference, the ram air would be worse, etc. It wasn't, according to the dyno I tested on at the time. It wasn't better either.
I'm sure a person can argue that either ram air setup doesn't really pressurize the incoming air. I'm sure a person can argue that the ram air system yields cooler air to the engine Vs the CAI since the inlets are well above the hot street. I'll bet there are a few other things as well. Bottom line, I doubt it makes much difference at all which you use unless you have an all out race engine...

WS6 ram air hood? No question about it, straight shot, it works. Don't compare the SS hood as they are different.

Re: 96 SS LT1 Air filter
Why would anyone even consider getting rid of the SS induction? Doesn't make sense to me. It was my understanding that the stock '96 Z-28 put out 275 HP. The SS with the direct air induction hood and SLP exhaust puts out 315 HP. I am not happy about trying to find a replacement air filter but I am not going take a step back in HP to install the stock air induction set up.

Re: 96 SS LT1 Air filter
You need to compare the correct numbers.
Dual-cat LT1's in the Z28 96/97 were rated at 285HP. The base SS package increased it to 305HP. It was only 315HP if you ordered the optional high flow exhaust system.
No one is suggesting that you replace the SS induction with a stock induction. What they are suggesting is that you may get better results with a CAI that was intended to replace the stock Z28 induction. Both offer the advantage of colder air. The dispute is whether the SS induction, being directly on top of the engine, suffers from heat soak, and whether the complex bends in the system (air has to find its way through the scoop baffles, and then make a series of turns totalling 360-deg) reduce flow. Is the SS induction as effective as the typical CAI that has less bends and no baffles?
Then there's the issue of whether the SS scoop is in a good location. Typically, once the air hits the front edge of the hood, the flow separates and leaves a dead zone immediately adjacent to the sheet metal. That's why NHRA Pro-Stock cars move the scoop opening about 15" above the surface of the hood.
It's not as obvious as you seem to assume.

Re: 96 SS LT1 Air filter
you might see like 1/10 of a hp differance... and if your intake is getting so hot that its radiating heat through that thick material the air intake is made of you have other problems beside what cai to run 
and its not like even on say a moroso or K&N your "forcing air" your motor is still pulling air in. and at 1 instance i had a moroso cai on my Z28 and the factory SS intake on my 97 SS...(obdI conversion) ran my data master on both cars running side by side and there wasnt a significant differance in the ait... but as for a filter if i remember a K&N from a jeep fit in the box. at that time K&N didnt make one for our cars
