Regular Intake to Ram Air? Hi all!
I have a 1995 Trans Am LT1 A4 and I was wondering if anyone has or has thought about experienced...... etc. on changing the regular intake to the WS6 style Ram Air? Is this possible and about how much would the stuff run??
Any help would be great!

I played with that. The K&N set up is worth a few hp. I dynoed one (3 pulls) then installed the K&N while the Camaro was still sitting on the dyno. Three pulls, averaged 6 or so (been a few years LOL) more rwhp with the K&N. Thought "Wonder how much more the straight ram air box off my ram air TA is worth over that curved K&N ducting?" Surprise! Nothing! Made identical numbers.
So, I wondered how much power the ram air is worth? Friday night test & tune: ran it with the holes in the hood open, then taped up. Another surprise! Ran the same. I do what I call A-B-A testing like that. Ran the ducts open, taped over, open again. Found no difference. In different weather there may be a little.
So, it appears the K&N kit is as fast as a ram air hood, etc. These cars won't run fast enough to "ram" more air into these engines at WOT anyway. They suck air in at a much higher velocity that any ram air effect we will ever see. Cooler outside air would be where gains would come from. So different weather might show a little bit.
Long as I have done this, I still find things that surprise my that either help, or was sure would help but don't seem to matter.
I about wear my **** out testing, but I still like to learn.

I think Ed covered the performance explanation, this will give you a good idea of the cost, $865 for hood and intake, before upgrade to chrome insert. http://www.xtremeautosport.net/servl...,-chevy/Detail
The K&N FIPK is more then enough air for a 350ci LT1.
During my dyno tune we pulled the elbow off my TB to chase a dip in the graph that my tuner thought may be an intake restriction, and I was surprised to see an open TB only dyno ~2rwhp less then my FIPK - and even that was mostly due to the filter starting to get dirty.
I got my TA with the WS6 functional hood and airbox and it looks cool and you can hear it breathe...but damn is it expensive and I doubt it is worth any power (maybe at ~150mph? That is where sportsbikes list increased HP numbers, and their ram air scoops are perfectly engineered to be in the correct spot).
I definitely wouldn't do the swap looking for power, only if you want the look and easy to clean filter

of course its possible, the only real modification i did to the car was slicing some sort of wire loom open a bit so i could get more slack for the MAF to come over since it sits right between the ramair box, a short piece of tube and then another short piece of tube going to the TB. Its an expenive CAI since your buying a hood in the process, but it looks awesome.

Verdad Gallardo The scoops on the lt cars are too low and far back to be in the airsteam to get any ram air effect going. ive tested the slp kit and jaam ram air kit with a.water column gauge.and the intake is pressurized. Then theres a bunch of results with the ls guys picking up mph with ram air kits.
I have logged enough runs that I can tell you your intake temps drop as you go down the track. Too far down to help ETs, but a little MPH. Less than one MPH for my race car. No ET. When I say no gain, I mean ET. Only thing that matters to me. MPH won't win a race. ET will.

Thanks for all the responses guys! Yeah, if anything it probably would have been more for the look versus any actual performance. So, the K&N set up is the way to go? ANd weren't the 96-97 LT1 WS6's the only ones with "true" ram air? I thought I read somewhere that the 98 and up WS6's were not.
The Lingenfelter Supertube is a very nice cold air intake, I've run one for 5 years now. No fitment issues and looks OEM. Check it out and they have it on sale now for $140 bucks!!! I hope they aren't discontinuing it.

Ram air lt1 Here is a ram air setup on my lt1 ws6, the orginal airbox was rotted out. So I switched to a K&N Fipk with a cnc cut one piece that was bent and not welded nice and light. It has been painted black and more weather stripping added since pics. It seals well to hood.

Right, I understand that the it had the Ram Air hood but I thought I heard somewhere that 98 and up were non functional. I could easily have heard that wrong!
98+ trans am were ram air still, they have a raised lip base for the air to flow through. It is the 98-02 camaros that aren't functional, but the 96-97 ss's were functional, although a horrible setup.

Thank you for clearing that up for me. I think I am going to go with the Lingenfelter one CAI, but before I do that, I need a new fuel pump. As I understand this is a bit of a laborful task. ANy tips there?
Oh, yea, 93-97 LT1 Firehawks also had a different ram air hood, air box as well than the 96-97 WS6 cars...not sure which of those is superior.
Car and driver:
"Lurking behind the Firehawk's beak is the Trans Am's stock LS1 V-8 fitted with a type of Ram Air induction that uses a lower-profile airbox than that in the WS6. It snorkels through SLP's own composite hood, which mercifully has smaller openings than the WS6's wildly flaring nostrils."
