Just Lid vs Whole Kit Im looking at the SLP Cold Air intake kit vs Just the lid. Ive heard stories about how the metal box and the belows give an extra X horsepower and then theres the stories about how it gave nothing and you can just save the extra 100 bucks.
So Im here to ask the experts...has anyone ever dynoed just the lid vs the entire kit?
I have a 98 Formula with just the Regular firebird hood that I plan to eventually fully build but for now its just getting the exhaust and Cold air mod plus the free mods

The Slp lid is a great start you will gain about 4-6 horse power to the ground but you will gain low end tourqe and you will definatly gain throttle response. the metal box you're talking about will get you more air in, but its really not nessisary and you will not feel much of a difference cause you gain volume but not enough velocity. With the SLP lid your gain velocity cause the volume you already have is plenty for a stock intake manifold, throttle body, and stock MAF sensor. Once your intake manifold, throttle body and MAF sensor are larger then 85mm thats when the "metal box" mod will have its greatest affect and thats when the stock air lid will restrict you the most... for right now i say get the SLP air lid and once you port and polish your throttle body and MAF and once you get a larger intake manifold do the metal box mod so that you gain a bit more volume for their larger size.... not to mention it will make your engine louder

No difference on the dyno. People have reported a bit of improvement on the track and at speed however with the kit, say FTRA (Fast Toys Ram Air kit). Only downside to the kit is it blocks some of the wind that would normally hit the radiator to scoop the air from under the car and routing it to your air box.

Maybe you can explain something to me, that I've been wondering about for sometime. I fail to see how your product improves airflow over the free ram-air mod alone. With FRA alone, air is caught by the front air dam, and forced up in front of the radiator, and sucked directly into the now exposed air filter. In contrast to a setup with your product where only the air flow that happens to be caught in the very narrow "tube" (for lack of a better word) and then gets forced up to the airbox. But, all the air around the tube that, in a FRA setup, normally would be forced up to the airbox, now has no where to go. In fact the only plus i see to your product is that it makes it easier to seal the airbox, so only air coming from under the car makes it to the airbox, sealing out the air from under the hood. But that hardly seems worth $180.
Free air mod is not even close to the FTRA

Gains
E.T. 0.073
MPH 0.456
not real good for the price

At the 1/4 you are probably looking at 10-20 hp or 1-2 mph gain!
Kit is definitely pricey though
They need to make it out of plastic and sell for 100, I'd bet they'd make a killing

Verdad Gallardo ^I agree to that too. less heat soak from the radiator.

All the gains from install university are from the 1/8 mile as stated in the other posts. With that being said, ram air effects increase with speed so if you are already seeing a gain in the 1/8 mile, you are going to have an even bigger gain the in the 1/4 mile.
Take a look at the VE improvements and also the fuel economy improvements as well. The FTRA is working very well.
We made the kit out of T304 stainless so it would last the life of the vehicle. There is another company that makes something similiar out of plastic but they have had some issues with the product being damaged on curbs and it also sells for a higher price and does not include a block off plate to disable the kit for bad weather or testing.
When we did our own testing, all gains were over and above the FRA mod. Other kits that we tested that do not go all the way down to the air deflector to directly channel air did not show any improvement over the FRA mod. Other kits also did not properly seal the air box which mean they can never build any kind of positive pressure.
Considering the FTRA will pay for itself in fuel economy savings, provide a very good performance increase and will last the life of the vehicle, we feel it is a very good bang for the buck.
