Done with Mina Intake. Where to buy Cold-Air?
 
Hello All,

I have been using the Mina Gallery Intake for about a year now:icon_no:. I have noticed that on hot days my car is losing power most likely due to the heat in the engine bay getting sucked in to the intake.

Does anyone know where I can purchase a full cold-air intake?:icon_denk:

Thank you for your help, alex

I think the only option is building one yourself.

WhiteXKR 12-17-2011 10:19 PM

This is the only one I am aware of:
Paramount Performance Ltd - Jaguar XK8 and XKR Engine Upgrades other than custom. I think it is actually somewhat of a generic BMC Carbon Dynamic Airbox and filter though.

The factory box is actually a cold air intake...you might just consider using it with a K&N panel filter.

avos 12-18-2011 02:49 AM

+1, the stock airbox is a cold air box and works fine with a K&N panel filter.

Reverend Sam 12-18-2011 08:55 PM

99% of the "cold air intakes" I see advertised are actually hot air intakes. A cone filter in the engine bay is just sucking in hot engine bay air. The intake on the XK8 takes in air from outside of the engine bay between the front left fender and the left "wall" of the engine bay. You can see where the actual intake point is by removing the front right wheel well liner. About the only way you'll get air that's any cooler would be to run a pipe up to the mouth in front of the radiator, but then you're going to have to deal with the friction from the extra length of pipe. Then engine is going to have a harder time sucking in the air unless you make the pipe much larger in diameter, and I don't know where you could actually fit the pipe.

Cliffs: The existing intake is about as cold as you're going to get without a lot of metal work.

XKRacer 12-19-2011 02:06 AM

This is what I fit which is a CDA box, you dont have to have the induction pipe you can re-use your own....

This is then piped down to the front of the car

How do you have the induction piped up to the front and how did you mount it. Is it in the grill? Could you list the parts you used? Also were did you get the Polished Covers for the strut mounts? Clean touch and I like it.

1. XKRacer is the king of the XK.

2. Check out his website at www.paragondesignuk.com, and your questions will be answered. You will also be tempted to ship your car to England and be relieved of vast sums of money. But your car will be the best in town when you get it back.

:icon_redface: You make me blush :icon_cool:

But Coupe is correct I make all the stuff you see myself, but to be fair I did get the coil pack covers made by someone else this time, just takes too much time.

You do need to remove some metal, like this

Attachment 167920

This is so the pipe clears as much as possible the wheel arch liner and the headlight, take a look through my photo albums, you will see plenty of XKs I have done there.

I am changing the location of my air box again to something similiar to avos and put my air box inside my front bumper, not sure if I will go enclosed of exposed, I will have to ponder that.

Some more bling to entice :icon_wink:

Have no direct experience with the CDA one, but you would also need to have a bell house shaped inlet (or is that included)? Anyhow I never considered this one as the surface area of the filter is only about 50% more than stock (might be enough for some though).


I use now a K&N RE0920 cone filter that fits nicely direcly under head headlight in the bumper. No need to enclose it, and it has another advantage that there is no bend anymore in the intake from the maf downwards. And last but not least the RE0920 has about 120% more surface area ;-)

XKRacer 12-20-2011 05:18 AM

The CDA100/150 is the one most fit, the next size up is too big to fit in the standard location, I do remember reading these filters are good for vehicles in excess of 500BHP but no more than 600, so for most XKRs it is fine, if you are going over 450BHP I would not recommend one but go for something bigger like avos has mentioned or maybe a large ITG cone filter

avos 12-20-2011 05:35 AM

Remember that even a stock 4.2 is producing about 470 BHP (400 net and about 70 for driving the supercharger).

So once you start playing with pulleys on the eaton, you want to biggest filter avalaible. Supercharges are very alergic to vacuum, the more there is the more power they consume from the engine. The CDA is more then $300, whereas the k&n-re0920 can already be had for $40 and will perform better and longer (though with a little more work). You can even make it stock look with the stock airbox to cover where the piping is going. But each to their own ;-)

I am very interested in the top shock mount covers... I checked the website, did not see them. Is this something we can have made? If so, any idea what you might charge? They really look great! Btw, the entire engine bay looks great, as does everything on your site.

They are on my Engine Detail page, they cost £175 for the pair, for that you get the caps, stainless dome headed nuts and stainless washers.

I have a set in stock and enough material to make up another set if anyone is interested.

jamjax 12-20-2011 08:09 AM

Racer;

OK I am officially a goner......I saw the red powder coating on the Super Charger and said to my self that is nice...then the yellow one...oh that is striking....the white again very nice....but the green made me say 'gotta have that' with the green medallions and wheel caps on my car.

But then I remembered I want to do Avos Twin Screw conversion in the Spring and wonder if that uses the same housing as the Eaton?

Yep just checked....score!

'Power and looks' the perfect combo.

Racer ever do a Zircon Blue powder coating on the SC?

The Green matches the Italian Super Model Wife's eyes when she is mad.....try not to see that very often but then she does look even better...which pisses her off even more when I point it out....it's kinda like having a supercharger for green eyed lasers...I just can't help myself.

As my Daddy used to say "I get my laughs but it's risky".

cheers,

jj

I have not noticed a light in the engine compartment... Do you have a fix? Could you fit those beautiful strut mount covers with an LED light?

JamJax- Polish the Supercharger and then clearcoat it with high temp clear... The problem with paint/powdercoat/polish&clear is- it does hold in the heat slightly... Polish and no clear is the best but it wont last...

A polished SC MMmmmmmmmmmmm. Thats Sharp....IMHO

XKRacer 12-20-2011 02:16 PM

At the end of the day you can paint a supercharger any color you like, they do get warm but not hot enough to make the paint come away as long you adhere it well in the first place using an acid etch.


And yes I could fit an LED ring into a strut cap

Count_Damonee 12-20-2011 02:37 PM

XKRacer
 
If you could fit them to my 2005 with a LED light ring, what would you charge for them. On the top of my mounts I do have lines that run close, how do you compensate for them?

I am definately interested in them... Now do I mount a switch in the engine compartment,,, HMMmmm,,, or inside the car?

Where would the easiest place to pull power for this application?

XKRacer 12-20-2011 04:13 PM

The lines you mention is the wiring for the cats suspension this is accounted for with every set of strut caps sell regardless if you have cats or not......

Personally I would run a constant live from the main batter wire connected to a plunger switch so the lights came on automatically when you lifted the hood.

The main wire runs to the starter and alternator on the right hand side of the engine bay, there is another going to the right hand side fuse box in the engine bay, you could either link the lights or run 2 plungers, there are many options.

You may even be able to use the micro switches on the hood release that tell you the hood is still open, you could run something along side, like I said many options

XKRacer 12-20-2011 04:15 PM

Price wise I would guess around the £250-£275 mark

Count_Damonee 12-20-2011 04:30 PM

XKRacer
 
I have 2 coolant lines that are held in place with a stay that screws to the mount bolt on the leftside of the car,,, Our drivers side..

Price- How much is it in Benjamin's,,, US...

I guess I need to pay in Pound Sterling...

workoutman0011 12-20-2011 06:24 PM

miami you probably seen these pics in a different thread but this is a cold air intake. If you look at some others they have this setup but probably alot nicer look. throttle response was defenitly shaper with this compared to stock JAXKR had this and made it look incredible mabe give him a holler

Sean B 12-21-2011 11:09 AM

Has anyone utilized the vents on the R? a dual duct into a short fat induction tube? Or are the vents too far back?
I'd like to see something like a shallow filtered air box attached to the bonnet, that closes onto the induction tube.
How much movement of the rads is there on an XK? can they be moved down for example? Another thought would be a true ram air through the 'mouth' of the XK, using space above a lowered rad package. Ali sheet ducting riveted and a K&N? like on TVR's.....

avos 12-21-2011 11:57 AM

The vents in the bonnet are there to extract air from under the hood, so not a place to block outgoing air and then suck air from.

Once you get air from the frontbumper area/fender you are already enjoying air comming in from the nose at a positive pressure, though it will be minimal. There is a high pressure zone close to the window, so there if space would allow you could do something like that.

Not sure if it is worth the effort to make a ram air system when driving under 100 mph, but above it is becomming another matter. I think something like the new XKR-S ram air system is relativly easy to make for someone like XKRacer if I had to name one ;-).

XKRacer 12-22-2011 10:26 PM

This might be a big enough hole to get some air in :icon_wink:

Bhpbug 12-22-2011 10:49 PM

As for the "cold air", I was replacing the front bumper under-cover on my '03 XK8 when I noticed the two indentations on each corner. They look like they were suposed to get corner lights, I cut-out the indented area and added some screening... this does seem to let some more cold air in and up-to the air intake on the right hand side. Call me crazy but, I swear my car does run a bit stronger now... may be my imagination?

I'm not so sure, they look to be more about styling than anything else. After all the XJR's have the same engine package and no vents....with no overheating? I do see how Jaguar justify heat and airflow though.

@ XKRacer - that looks Ferrari 550, dun't it?

I never spoke about overheating if you wouldn’t have vents, but you should know the effects of heat on performance right? Styling could of course have been a reason (I wasn't part of the design team), but it just so happens that the vents are at a spot where there is suction, which aids in the total cooling, coincidence?

JgaXkr 12-23-2011 05:03 PM

I remember when they were first building the XKR a comment was made by a friend of mine who worked for Jaguar. He said they were having a problems with under hood temps. That may be why the XKR has the louvers. The XJR has quite a bit more room under the hood so it may not need the louvers.

Oh lord. Don't tell Xenophobe!

Reverend Sam 12-23-2011 09:08 PM

I'm sorry, but most "ram air" scoops on hoods actually have negative pressure at the opening. The hood basically acts like an airplane wing, and low pressure on the upper surface of a wing is what lifts the airplane into the air. That's why the vents on an XKR work. They are sucking air up out of the engine bay. Someone should really design a pair of copper heat sinks than mount on top of the intercoolers. They would really improve the efficiency of the intercoolers.

The only place you're going to get ram air is very low on the front of the car, probably between the bumper and the ground. Even the air going into the grill probably isn't going to be at positive pressure. I'd bet that a significant portion of radiator cooling at speed comes from air that gets trapped under the car and is then drawn backwards up through the radiator and out of the grill.

I'd guess that ram in XKRacer's pic needs to stick up another inch or two to really benefit from ram air. It looks cool, though.

Here's a pic of the pressures on a wing which shows how strong the positive and negative pressures are above and below the wing.

http://www.mh-aerotools.de/airfoils/images/veldist2.gif

And look at this funny car. They put the intake so high for a reason. Up there the intake is in undisturbed airflow which actually forces air into the intake once the car is up to speed.

Speaking of inlets for air boxes, Tony, have you come up with any sort of grill or edging for the standard one? I stripped off the old foam from around mine due to its rotted look, and am looking for something to enhance it with.

Attachment 167803

It is the same stuff you will find on some of the edges in your engine bay, easy to buy and easy to shape




Getting back to the Rev statement, which he is correct, the best place for an air intake on the hood is at the back, where the screen meets, you catch the air rolling off the screen which creates a high pressure area forcing the air in, but it does not give a good styling look so is not done by production companies but is done by a lot of race cars. The only other option is it has to be front facing and not just flowing over the hood, this is a design alot of companies do use, it is not as good as at the back but does work well.

My hood acts as the lid for my air box and will feed the throttle bodies well, I would be curious to measure the air pressure inside, maybe one day
