I've got a ws6 air box sealed with a chrs1313 and a fast toys 104 lid speed density. My 408 made 555 through that set up. My tuner removed the lid and ran a open bellow and the car picked up almost 16rwhp. He said to unseal the air box in the front. Would I be better off using the true ram air effect or should I seal the front opening to the hood and allow both directions of air flow.

Very interesting! I was under the impression that sealing it was the better way to go

Have you thought about doing something like this? On your setup, I bet you'd pick up quite a bit.

On a dyno, with the lid off it will always make more power even with fans going to it. Though when actually driving the car, you will make more power with your current set up. Dyno fans cannot produce the amount of air being pushed that actual driving can.

Pretty hard for ram air to work when the car is just sitting there.

Also hard for the ram air to work if it's unsealed.

If you really want to know, take it to the track and try it both ways

Completely agree!!


As a former owner of a 1313 non AC version equipped SS, you won't see a damn thing on the dyno. Now, go do some street tuning on a "secluded" road and you'll see the benefits IMMEDIATELY of what that system does.

I still think a custom 4" intake with velocity stack will blow a Chris1313 out of the water on the track.

I had an ac version, switched to a non-ac and saw zero mph gain at the track. Weather was even a tad even or better and the car was lighter. Just as a tidbit of info.

+ however many times it's already been noted. Ummm, how is this a relevant test when the effects of RAM air cannot be measured on a dyno? Chris1313 RAM air has more than proven itself w/ posted track time slip information. Test it there, then the post becomes relevant.

Dyno racing or 1/4 mile racing? In one the car remains in place. In the 1/4 mile the car is moving down the track.

If you think a 4" tube alone is going to outflow a monstrous scoop that's FORCING airflow into the lid (enough to even blow the stacked weather stripping out from the factory lower lid bottom) you are sadly mistaken.


The 1313 pressurizes the intake tract. A 4" tube can't. It's not physically possible.

Dynos are for tuning not racing.

Ram air I just not something that can be dyno'd unless you can artificially produce a 110-120 mph wind against the front of the car.

We'll have to agree to disagree then. All I know is Samsul and Martin at Tick said they picked MPH and ET's at the track. Here is a quote from Martin in Shane's thread.

"At the track mine was worth a good bit to the 1/8th. Nearly a full mph and a full tenth. In the 1/4 I can see the gains being even larger."

And this going from the Chris1313 ram air to this setup.

^^^The only problem I have with that is that my ets and mph constantly fluctuate some. That little improvement is kinda within a margin of error in my eyes.

That could very well be, but I believe that both of those guys have a ton of passes under their belt with both setups, so having a greater sample to pull from both ways helps legitimize their conclusion.

Testing showed the bottom breathing lid setups (SEALED SYSTEMS) produce up to 3psi of pressure in the manifold at the track. That means the ram air actually works, something the muscle cars never got right. Shaker hoods and old school "ram air" produced more power due to drawing in fresh clean air from outside, zero ram effect with them.

I'm sure it limits airflow in low mph such as a dyno, no doubt about that as it is designed to take advantage of mph to create more power where you can use it. Would you rather have more power when fighting for traction or more power when fighting for mph? No brainer take the traction and big end power!!!


Velocity stacks work on a different principle. Apples to oranges IMO.

I picked up power one way or another lol.
