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...

 

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

 

@workoutman0011

This is exactly what I am looking for.

Thank you

 

Here a a few photos of polished charge coolers, they were not clear coated just polished.

 

That intake pipe looks very similar to one I may have produced.

 

Very nice set up! Looks great

 

Now that looks SHARP.... Polished SuperCharger...

Its on my Honey-Do-List

 

I see you fitted the coil pack covers, look very nice, have you fitted that front bumper yet??

 

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.....

 

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 ;-).

 

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

 

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?

 

It does a bit.... But that is my intake for my air box

 

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!

 

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.



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.

 

Look at this pic I posted on the last page



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
