Improving the stock intake: More flow, lower IAT's & More SC noise!

Hi there
First of all let me tag @Stuart@VelocityAP as he has already started to look into this for us as it will indeed require his expertise and production abilities to turn this into a commercial and viable product for us to purchase.
RAM AIR & Lower IAT's
I did this on my Mustang, that car has the ability to monitor IAT (intake air temperature) displayed on the dash, by doing this it helped lower those temperatures 3-5c and on the flip side if the car had been stood a while, say whilst waiting to run at a drag strip the IAT's had dropped back down to ambient more or less by the 1/8 mile, as such the ECU was less likely to retard spark resulting in more power available. Can be worth a tenth or two quite easily if you've been idling or engine off a while and everything is heat soaked.
Also if you can force air into the sealed air box as they are on our F-Types you can create a RAM AIR effect, which manufacturers like Porsche incorporate on most of their cars now as they claimed at highway speeds it can gain around 10BHP.
As such today I visited Jaguar to have a new gloss black grill bar installed due to removing my plate the old one had holes in it and well I did not like the holes, so I took this opportunity to thoroughly look over the stock F-Types air intake system and where the snorkels for sucking air in are positioned, let the pictures do the talking:

![](https://i1145.photobucket.com/albums/o504/Gibbo205/SVR/11.jpg)
So as you can see that are indeed two snorkels positioned behind the bumper support bar, so quite well positioned but of course air is not been rammed down their throats, they are simply sucking in air from their surrounding including hot air from the radiators/intercoolers.
If one was to essentially build upon these so they can only suck car from the front area and even better extend them towards the grill would result in a ram air effect and of course lower IAT's, the only risk is more water ingress but the airboxes do have holes in the bottom of them as even the stock design lets water in when at highway speed in heavy rain, so this is not something to worry about.
I am probably going to make some make shift (cowboy) direction ducts to feed only cold air from the grill out of some cardboard, which I shall spray black and then waterproof until a more professional solution is available from Stuart at VAP or a company known as Velossa Tech Design specialise in snorkels, they made the one for my Ford Mustang and it fitted very discreetly behind front grill and worked a treat.
More SC Whine!
I know we already have a thread on this but makes sense to also include it here and Stuart at Velocity AP has already agreed to work on this project for us.
The stock intake tubes after the maf tubes have sound resonators/mufflers in them to kill intake and SC noise as can be seen here:
![](https://i1145.photobucket.com/albums/o504/Gibbo205/SVR/12.jpg)
![](https://i1145.photobucket.com/albums/o504/Gibbo205/SVR/13.jpg)
You can see the very thick walls which accommodate the baffles with sound suppression holes in them to kill intake noise, well many of us here want more intake noise, particular SC whine so inserting and welding/gluing a sleave in would bypass them but even better would be just some nice thin walled (strong) aluminum tubes in matt black ceramic coating to give a factory look but along with more intake noise and maybe a touch more flow rate.
MORE POWAH!
Well not necessarily more power, but lets say optimal power, so replace the two paper filters in the stock air boxes with a K&N element filter for those who do not mind oiled filters or a foam performance filter for those who dislike the oil type, along with the RAM air snorkels at highway speeds there could be realistic gains of 15-20HP.
I believe this is a way of improving our stock factory intakes, so reasonably warranty friendly but more importantly more noise and the car making its true power more often due to lower intake temperatures.
I hope Stuart or Velossa Tech Design can help with the snorkels and we know Stuart has the rest covered off.
As I believe all cars runs the same intake setups in theory this modification will work on all the V8 models and possible V6 models too, but am unsure on the V6.
I am confident with the above and the lighter 2PC brake rotors I've organised with Wortec I can run an 11.1s quarter mile which for a stock SVR I think will be going very well.![Smile](https://www.jaguarforums.com/forum/images/smilies/smile.gif)

UPDATE!
Yep I don't mess about, just had a conversation with the designer at Velossa Tech Design, attached is an image of the kind of stuff they can do.
Anyway in short he says he could make us snorkels for our intakes and in short were looking at the following:
1. He needs an F-Type V8 or V6 (If snorkels same) in South Florida area for a couple of hourse to do 3D Scan
2. Group buy, needs about 20 people!
3. A rough price of around $250 for the dual intake snorkels in any colour you wish.

You can have any colour, that is not an issue.
The reason he needs 20 is for the cost of mould etc. but you guys can have any colour finish you desire.

Can we make it work so that it is compatible with the eventuri intake or other forms of aftermarket intake? The stock snorkel does go to where the eventuri intake would be.

Yes parts 11 & 12, the Velossa Big mouths shall fit on the top of them and sit directly behind the front grill next to wear you can see the foam behind the grill.
That foam by the way is for pedestrian safety, of course it can be easily removed, just pulls off, weighs nothing and it then leaves the painted bumper bar exposed so if you did remove it have some gloss black paint to hand.
Are parts 11 & 12 the same on both V6 and V8?

okay I see, so it turns the snorkel from a vertical position to a horizontal ram effect position.
I dont know if v6 and v8 are the same, I think on my v6s the snorkel goes further up than what you are showing me on your pictures, but at the same time, I am sure cutting up the plastic snorkel is easy to do.
The other thing I am worried about is water. If the stock snorkel is vertical that means water can't really get in right? If it comes horizontal towards the grill doesn't that mean water can get into the intake? If this isn't an issues and has been tested and the part can fit the v6s then sign me up, I want it in white, thanks!
Although, ideally, if they can replace the entire snorkel instead of adding the big mouth onto the top part wouldn't it be better overall? Just a suggestion

Replacing the entire snorkel would dramatically increase the cost.
Water gets in the stock design, that is why our air boxes have drainage holes in them.

The silencers are identical for the V6 and V8 alike.
Count me in, dependent upon the final design. I want to make certain that the placement does not limit airflow to/through the radiators.
Of higher interest to me would be a tube section that eliminates the air tube silencer (numbers 5 & 6 on the diagram).

Stuart at VAP is already looking into that for us and was gonna make some out of aluminium which are then ceramic coated in matt black to look factory, which I did put in my OP.
All been well VAP will supply modified air tube silencers to give more SC whine along with higher flow panel filters.
Velossa Tech will supply the snorkel add-ons to catch more cold air and create ram air effect.
Lastly can someone confirm if the V6 and V8 snorkels are the same please?

Hello, I just wanna make sure we are talking about the snorkel going into the stock intake airbox. On my v6s, the snorkel goes all the way up to upper part of the intercooler/bumper
Can we make it work so that it is compatible with the eventuri intake or other forms of aftermarket intake? The stock snorkel does go to where the eventuri intake would be.

Gibbo, the snorkels on your SVR look to me to be a lot different to the stock snorkels on a V6 (see post # 10, parts 11 and 12). Different shape at the end (cut away) and maybe shorter and sitting lower down behind the grille. It could be that the "cooking" V8 and V6 snorkels are all the same and it's just the SVR ones that are different.
Velossa would need to get a stock V6 and a stock V8 in together to look and compare with each other and with your SVR.

The V6 and R use the same intake ducts (snorkels)
The R and SVR use the same air filter boxes.
This means that the inlet port on all the air filter boxes are the same and an integrated ram inlet duct that is designed to attach directly to the air filter box will fit all models.
P.S. I suspect that the ram air effect on power will be negligible with a supercharged engine. My interest would be to minimize drawing in hot air from around the radiator.
