The air box is open at the side, therefore, no vacuum nor pressure is produced such that water can be drawn into the intake.

This is the same reason that there will be no ram air effect by adding the scoop. Your only chance of getting a ram air effect is if you seal up the side opening in the box!

If you do not seal the side opening of the air box, then any excess air pressure that is blown into the box via the scoop will be blown out of the side opening...you just eliminated the ram air effect.

 

Sorry for the delay. Our CARB certified Technition has lost his hardrive. Therfore we lost fuel curve and HP dyno information on the 2004-2007 5.4 F-150. Looks like we will need to run it again.

So we will need to run a stock 2w/d 5.4 F150. Must be completely stock. If you are interested let us know? Contact Bill or Daniel at Volant 909-476-7225 to make an appointment.

 

So you are only going to run 1 truck to establish the A/F ratios when running the Volant I would think you would want to run more than 1 truck

 

Let's see, Ford has a budget 10 million times that of Volant. Ford probably tested 100 trucks for AF.

So that means proportionally, with Volant's budget, they should test 0.00001 trucks. So if Volant is testing 1 truck, they are doing 100,000 times more than Ford did!!

 

This kit took about 8 months to build. We tested many trucks. We are currently shipping the (patented) third generation duct after much continued testing. I am not going to quote the claims that we gained without the proper written backup from a certified (CARB) technition. We own our own Dyno and could easily produce this result but would only produce more keyboard B/S. So I thought we would offer a fresh dyno run with a forum member and show the results. Obviously we would give he or her a day at the Dyno and a free kit. Results and photo's to be published, same as we give to Sid

Excuse me, but what exactly are you smoking, 'cause I want some lol!

A small shop like TP has dyno'd thousands of F150's, so the size of the organization means little - it's focus and attention to detail, and doing what is important. Given the acknowledged diverity of the platform - you need to test as many as you can.

Good to see Volant has done many more than K&N ( last count for K&N was all of 3 trucks - wow) ... And if they focus, I'm sure they can resolve any outstanding issues and produce a truly competitive product.

Understanding the unique quirks and testing, testing & more testing, is the key. This approach is proven to work.

And - I really think Ford has done a few more than that .... that's funny right there ....

 

Did TP design the AF1?

 

Not that i'm aware of!!!

 

He did a lot of the R&D - mucho testing, and was a major factor in the tube redesigns for the 04+ 5.4 3V's.

 

Huh that's pretty cool

 

I ordered the volant intake with ram air scoop an noticed a helicopter like sound when running around 3k rpms, I tried several different things to figure the cause , I traced it to the main intake tube from the throttle body to the air box. Still not sure why it makes the sound that it does, has anyone else had this problem? It's also a 2014 stx with 5.0

 

Way to revive a 7 year old thread

 

And way to reaffirm that Volant is still producing the same junk intakes that they were 7 years ago

OP - as you are probably aware, that isn't normal by anyone's measure (although the intake manufacturer would likely claim it is). You've gone and upset the precisely designed NVH that the OEM intake possesses. So yer result is unsurprising.

Yer solution is simplicity itself - return that POS crap fer a full refund. It's not like that thing is providing any benefit whatsoever - The rest is just BS - Marketing Maskirovka 101. Both the stock intake (and exhaust) on yer 4.9.oh-oh already abundantly exceeds the flow requirements of yer unmodified engine. And contains no hidden whirlybirds ...

good luck to ye ...

Now that was a good read, and a good explanation of MGD's disapproval of Volant .

I bought a used Volant kit for $100.00 so it wasn't brand new, bought it to dress the engine bay and make more under hood noise. My gains ( via gryphon programmer 0-60 & 1/4mi run ) stock w/ tune, with intake w/o tune update, and then w/ updated tune, rendered no increase worth the intake. Glad I bought it used . So I find intakes useless for performance. Just dress the engine bay up and sometimes sound meaner. I however did not gain a lot of volume.

I would like to find a Ram Air duct however, didn't know they made one for this generation.

 

Darren, at the speeds you can drive, any ram air effect you can achieve is negligible. Save your money.
