LT1-LT4 Modifications - cai v.slp lid

i am going to get a cold air intake soon and i need to know IF my 95 formula will be able to do the slp lid or if i have to do the CAI and elbow route?

if i can do both where will i see the most gains? (ported intake and 58mm tb in the future)

I've done both, hands down the lid is head and shoulders above any CAI kit.

^This!

A buddy of mine, who I'm sure will post here soon enough, tried the Lid swap and a Moroso CAI back to back at the track. picked up something like 2 tenths and 1.5mph going to the lid swap over the CAI.
I have my lid and ls1 k&n on order for my own swap...

Does the lid fit under the 93-97 WS6 hood with out having to chop the radiator support?

The lid won't bolt right on by any means. The CAI is the easier route to take, but some people have had success with the LS1 lid swap.

I am doing a lid on my 1997 ws6 soon. From what I here its not hard at all to get a camaro airbox and lid to fit, but the ws6 ls1 airbox and lid is taller and will require more mods to fit on a lt1 ws6.

read these, if you don't find exactly what you're looking for, there are many more threads on it. :)

The general consensus many times over basically comes down to something like this:

stock LT1 airbox < Aftermarket CAI/96-97 SS Ram Air < LS1 lid/LT1 WS6 ram air

I am doing a lid on my 1997 ws6 soon. From what I here its not hard at all to get a camaro airbox and lid to fit, but the ws6 ls1 airbox and lid is taller and will require more mods to fit on a lt1 ws6.

Most claim the LT1 firebird ram air (ws6 or firehawk) is nearly or equally as effective as the lid style intake, if you had a LT1/ram air/ws6 hood, it'd probably be a much lesser headache to just go with a ws6 style intake, rather than a lid mod.

Do the Lid, you wont regret it.

True statement!
2tenths and 1.8mph
some people say its alot of work to instal the lid it really isnt any more difficult than removing/installing filter on a cai.....go for it!
Pay attention to this write up and you are 90% done

If you do it right with the ls1 radiator support ect it would be a worthwile mod. Most I see are just hackjobs that lay the filter on top of the radiator and condenser. I don't think people realize how much dirt is going to get past the filter since it's not sealed to the lid that way.

stock LT1 airbox < Aftermarket CAI/96-97 SS Ram Air < LS1 lid/LT1 WS6 ram air < LS1 lid with a sealed tunnel ram

I agree! and I added one more for ya :)

As the guy that did the writeup for fitting this under a stock hood allow me to address this:

1) Putting the filter on top of the radiator and core support is the only way to fit it under a stock hood.

2) You would be surprised how good the seal is on my car. Its all snug, I would not have left it that way if it wasn't.

3) As stated in my writeup, if the seal is NOT good enough for your tastes, you can use an LS1 filter basket laid across the rad/core support and it will seal better.

4) A hackjob it may be, but I'd feel like i was running around with stock manifolds if i didn't have this done... and for me thats worse.

The filter needs to be supported around the whole base for it to seal. Being snug in a few places is still going to let a ton of dirt past where it's not sealing. And the filter tray isn't stiff enough to create a seal on its own it needs the ls1 radiator support for that. Not to mention the lid isn't clamped down to the filter either. If this is a track car that's one thing but to have a street car sucking in all that dirt....

why are you swapping out an LT1 WS6 airbox for a lid? IMO the LT1 WS6 airbox is the best setup for an LT1 car with the LS1 being the second best and easiest for those people who can't find an LT1 WS6 box or don't have a ram air hood.

as someone who added the LT1 WS6 hood/airbx to a non WS6 car, i can say there is no cutting or hacking of any kind for that setup and it's the easiest thing to add if you have the WS6 hood.

Absolutely. The r/a hood and airbox was the first thing I did to my car when I bought it, and I'm glad. If you've already got the hood, track down an airbox setup. They are fairly rare and expensive, but occasionally you can get a good deal.

^suncoast creations sells new ones IIRC, around $300 or so.
