Hello folks.
has anyone had bonnet vents cut into their S-type bonnet? Maybe something within the Jaguar family like XKR bonnet vents?
would be interested to see some finished pictures if you have.
Cheers, Mark.

 

To let water in and risk problems & codes? No thanks!

 

🤣😂

 

Ah yes, the typical boomer response I was expecting.. not like anyone has ever manufactured something to divert water under a hood…. “obvious sarcasm”

I’d be interested in this as well, but I’m expecting more responses like his.

 

The S Type spiritual predecessor:

Coombs Bonnet Vents (jaguarmk2.info)

 

If you don't like the answer don't ask the question.

 

Expecting a "participation trophy" for that response? Inquiring minds want to know. (obvious sarcasm here too...)

 

I didn’t ask the question, I simply made that statement because anytime someone asks a question about doing something other than what Jaguar did to the car from the factory it’s met with negative responses like yours. With no thoughts as to the possible benefits if done properly. The link the gentleman posted above depicts the benefits of doing so, with ensuring the water is channeled in such a fashion to where it does no harm. On a previous vehicle I owned they helped tremendously. Granted it was a hood made from carbon fiber, but it had the proper channels for water that would divert it away to a safe location. As a result the car didn’t overheat at all and it ran much better.

 

Perhaps the OP could clarify the need for having a louvred bonnet on an X200.

 

That's false.

In any case, it wasn't negative - it was to caution which is something else.

Now... knowing it could cause issues and saying nothing? That would be negative.

 

Certainly didn’t seem like it. Looked more dismissive of the idea but regardless of how it was meant, I think it could be done properly.

If anyone has done it properly with taking into consideration channeling for water and such is an entirely different question of course. But an interesting one none the less. I would think removing heat out of the engine bay was the main reason why the post was made in the first place but of course no one knows as of yet. Least that’d be my interest with this whole idea in my S type R.

 

JagV8 it's a whole different world my friend. We have to embrace, coddle and be politically correct without offending inquiries posted on public/international discussion groups. Your real world knowledge/experience does not count as its not what posters want hear/read.

Now IMHO if one would like to spend the $$$ or has the expertise to louver a 15 plus year old S Type hood/bonnet with success, I say kudos and please share with the group! I do remember that dealing with an aluminum hood/bonnet is a very difficult thing to deal with, almost a lost art.

 

Sounds like a problem for Dave Kindig.

 

I'd hardly say that's false. Anytime people do something out of the norm around here you get 1 old guy disparaging a different approach and 7 more kowtowing to jaguar's engineers. Eventually you'll get 2 or 3 open minds willing to discuss the merits and downfalls of the idea. Like with most things, hood vents have nuance. Good or bad, could be either depending on execution.

Louvering the hood would be the exact wrong way to go about it. Well maybe not wrong but definitely the most difficult and, just speaking opinion here, ugliest.

 

Is it me, or have we forgotten that we are all on the same side here?
We all ❤️ Jags😃🎉

 

Only one? We need to increase our numbers. After all, it’s been scientifically proven that change is bad.

 

im getting more cool air under the hood by rocking a facelift hood on a prefacelift car. its the longer hood that allows for two slight openings by the grille

 

Maybe he's got plans for some street racing? Here's an example of a BOSS Jag.

 

That brown XJ6 - that's the boys from Hot Rod Magazine as seen on their youtube channel "Road Kill".
Funny, I seem to remember them having cooling issues and could've used some louvers, haha.

 

It's not such a ridiculous idea to add bonnet vents. I believe they were considered originally for the S-Type R. The under bonnet area is designed as a wet environment for obvious reasons so bonnet vents such as those used on the X100 series XKR wouldn't immediately risk durability concerns, assuming some consideration was given to where they were placed. They were used on the XKs without additional issues.

They would also help reduce under bonnet temperatures which the S-Type R can suffer with resulting in plastic parts and hoses perishing more quickly than they otherwise might.

Personally I also dont think stylistically they would look bad. They work on the XKR and would hark back to louvred bonnets on original S-Type racers.
