this is what i want for my XKR!

 

I presume you are joking?

 

Difficult to fit on a steel bodied XKR, this is from a aluminium version where there is more room between the hood en engine (and in front of the engine as well...).

 

Attached was the precurser ;-)

 

I have to ask, does it really offer much benefit? Or was it one of those see if you could sort of projects?

 

Still waiting for more info about the 90mm carbon intake...

 

I was not totally kidding! I know that the pictures are in the XKR with aluminum frame, but it could be a good idea to make a similar filter in carbon and have a bonnet cut to create the space needed, making a air dynamic as this....

 

The setup as I have it is more than sufficient for what it has to do (so with the cone filter under the headlight in the bumper), so this is not something I would be interested in.

Maybe they choose this way as easiest setup, and there is probably also some ram air openings in the bumper, but that just as well can be done with the single air tube on the steel bodied cars.

 

I was hoping to see one this month, but as it looks now, it may be next month (not under my control...).

In case someone wants to know what it’s about, see the attachment. This one is made by TLJaguar in the UK especially for the twin-screw kit, and they can be reproduced.

 

I have been asked to do this a couple of times.... Let alone the space issue you have the MAF problem.... A twin intake requires twin MAFs.... It is just not feasible..... The gains would be negligible

 

Avos, do you have any photos of your intake system you would be willing to share?

You can already see the path in the picture shown with the carbon intake pipe, here is another:

 

the question I posed is that normally the suction tube passes over the exhaust manifolds by heating the inlet air to the engine. In addition, with a central air intake dynamic, we have a natural extra pressure in the compressor with the increase of speed.
is for this reason that the jaguar racing Ferlito using dynamic central air vents for their race s-type and XF cars!
I think there is a reason!

 

This is my 90mm induction set up.... still needs dressing and a good polish but you get the idea..... I have had to remove a small piece of the bonnet/hood frame for clearance, nothing drastic





I am designing a special type of cold air feed using liquid CO2, this runs at -80 and the air passes over it should cool down alot.... in theory 20BHP gains maybe possible but we shall see the good thing is it will work on XK8s as well as Rs

You do need to fit some good shielding to protect the pipe from the manifold and cat giving off heat but that is not difficult...

 

It’s one of the reasons I keep much silicon piping (support by an inner aluminum pipe) instead of aluminum as it gives a little extra isolation.

However I personally think the gains of isolating the tube are very little(/neglectable), at full throttle for a stock car (with a 85mm id intake tube) the air is moving (if my calculations are right) at about 45 meter per second, so not much time for the air to pick up some radiated heat.

Also it’s only when you are standing still you get excessive heat form the manifolds/cats that heats up the piping, but much less when moving.

 

liquid helium is -452 F / -269 C

simpler, NOS is -126 F

Just FYI

 

I've got Carbon Dynamic Cold Air Induction in mine - not sure what effect it has but its there. I'm trying to get time to take pics to put up. Not easy though.

 

So what about a de-icer system ;-)
