I am in depending on final design quality and no radiator obstruction.

 

 

^^ That part. I'm more interested in gaining SC sound...

However, snorkel modification is a great idea, will follow this project!

 

Has anyone got any images of the V6 & V8 snorkel behind the grill so can see how they compare to the SVR ones please?

I guess a solution to fit all cars if the air box end is the same on all cars is a complete snorkel that replaces the current one and fits into the airbox, I suspect that will cost more though as its a lot more material.

 

Or just come up with different methods of cutting up the snorkel to make the aftermarket unit fit in various set ups

 

 

Count me in on the ram air, and also interested in the baffle mod/delete.

As much as I want to jump on the bandwagon, I "need" to see some performance impact numbers first, life as an engineer has it's burdens.
However, I definitely notice a change in performance on very hot days and I am pushing the car. Note, I have the VAP tune+pulley, but the stock cats. So Unhingd's comment on the hot air has me thinking maybe this could help some. Or maybe it's just a way to justify it.

 

I feel this is pointless without removing the other bottlenecks in the system, as others have mentioned.

 

Reducing intake air temperature is definitely not pointless, it help prevent the ECU retarding spark.

All car ECU's have a advance/retard tables based in IAT, if outside ambient temperature is 25c, but under the hood is 50c and the car is breaking in a mix of underhood hot air and fresh air it could be pulling in 35-40c intake air.

With the snorkels its possible to get that closer to ambient which will mean less retard on hot days and more advance on cold days, more spark advance is more power.

If anyone has datalogging equipment a simple log would show intake temperature versus VS ambient temperature, might be a case of temps are already close to ambient and this might not be much use or may show we can reduce IAT's a little.

Then at high speeds its possible to get some RAM air effect which makes more power, but of course only works at high speeds.

 

The stock intake is already quite cold air efficient. Adding two silly snorkels isnt going to change much, that much I can promise. Any drop in temp from a "ram air" effect would be noticed as air was rushing past the stock intake already. The "ram air" effect has shown to be about 5hp on big V8s pushing 400hp.

Im completely down for a new air intake system (hell, we are trying to create one) that provides more sound, and maybe a few HP at most. But this is only addressing the easiest to change, least restrictive part of the entire air intake.

 

Same!

 

I'm in, but just as an FYI...you can't add a "ram air" effect to a forced induction engine.

i applaud the effort, but this is a 1% mod

keen for the modified inlet purely for the added whine

a fun watch

 

Let's focus on the SC whine. That silencer has to go.

 

If you want to improve inlet air flow and reduce inlet air temperature a good place to start would be to measure existing flow and restrictions to air flow then when you have determined the restrictive part by measurements you know what to change and you have a reference value to compare to your 'improvement' to check that it is actually an improvement.
Same principle with IAT, measure temperature before and after supercharger. Reducing temperature, if possible before supercharger could be worthwhile, however if when under significant boost or higher ambient temperatures the charge air cooler is allowing temperature to get high (measurements again) then slightly cooler air before the supercharger may well make little difference and more benefits may be obtained from improvement in charge air cooling after supercharger.

I have heard of people 'upgrading' charge cooler electric water pump for a higher flow rate. Others have discussed replacement of charge cooler with a Laminova core (probably non trivial).

Or if you want serious bhp and have very deep pockets you might consider asking a supercharger manufacturer such as Magnusson or Harrop to custom build a TVS 2650 to fit the V8 Jaguar inlet manifold.

Another fantasy modification that's appealed to me with regard to seriously reduced IAT would modify air conditioning to use it to reduce inlet air or charge cooling water down to ideally 4°C.

Right I will get back to reality now, would I like substantially more than 550 BHP ? certainly, would I be able to use it for more than 1% of the time I drive the car ? very unlikely, although fun to try!

Almost forgot to say, interesting thread and I appreciate photos of the parts that you're considering replacement of .

 

I think you'd get a larger power gain simply by turning off the A/C.

 

Leave the a/c on & use this. I installed one on my 2000 XKR & the results were amazing. When I would accelerate the discharge temp of the coolant would go up to about 170, as soon as I started to back off on the throttle you could see the temp drop. I was running 20psi of boost with one of Avos's Twin Screw kits.

The Project 8 seems to have loads of supercharger whine based on the videos posted by JLR... it also has a different intake tubing system to the V8 F-type. I'd bet they removed the silencers to get that effect. Would be nice if the Project 8 relevant piece of tubing could be ordered as a part from JLR and fitted to the F-type.

 

Good shout!
Quick google does indeed reveal the Project 8 does not have silenced intake tubes, also air boxes higher up so no doubt create more noise, image attached.
