why has the uk got a bonnet scoop ?

Recommended Posts

When the bonnet is shut, there is a distinct path for this air to follow.

This the top of that path, it moves south quite a bit, to a specific location of the cyl head.

 

Now let's get on with our lives....

 

For your information I don't have a life :violin: and this is the most important thing in it right now :help:

 

Okay, the scoop does something. But not much, as it's only fitted the to UK cars and to my knowledge, the cars that don't have them fitted don't have any problems.

 

So, it just creates more drag at high speeds and fucks the cars aerodynamics :nyah:

 

And I hope you didn't just go and take that photograph to make that point, that would be sad :D

... to my knowledge, the cars that don't have them fitted don't have any problems.

The 'problems' would manifest as more frequent need for rebuilds when used often under sustained full throttle.

 

Hard to point this down as these cars will first fail through turbines spat from the exhaust (or they'll have a single, in which case the whole exhaust-temp balance is very different)

So, it just creates more drag at high speeds

a blown gasket creates even more drag, as it forces you to stop and call for help.

and fucks the cars aerodynamics :nyah:

it does affect aeros, yes.

So do other 'mods' that pass as 'improvements'

And I hope you didn't just go and take that photograph to make that point, that would be sad :D

I've got lots of pics on my webspace mate.

I just circled the alien part for you to admire.

In the States it is sold as a full kit, it is comprised of several Toyota parts actually.

So a scooped car will not require as many engine rebuilds as a non scooped?

 

Surely oil is meant to keep things cool internally, at all ends of the engine. IMO it may aid with some kind of cooling but Toyota obviously thought it doesnt make a noticeable difference otherwise they would all have them.

So never then. With a car this powerful and fast, where, except the salt planes of America, or an INDY circuit would you be able to sustain full throttle for prolonged periods of time?

 

Did they fit them to the UK cars because they thought the UK roads lend themselves to this type of driving?

 

I also take it you mean full throttle in top gear, achieving speeds in excess of 112 miles an hour that the J-Specs are restricted to?

 

Until someone can post something up proving this theory, and prove me wrong......... :blahblah:

We're not talking of sudden failures here mate.

More like increased chances of thermal failure as time goes on.

OEMs have to get it right, because even if it affects 5% of their production run, that could still be a few hundred cars to fix at their own expense.

 

A punter may never pin down this 0.05 probability, as so many other factors come into play for him/her.

Fine. So why only have them on some cars? And please don't say beacuse they were enforcing speed limits more stringently in America at the time.

 

Still nobody can tell me why 'OEM's' only put this crucial thermal stress reducing device on 10% of the cars it manufactured?

Dont know if its a wind up, but I am serious. I cannot see why toyota would only put them on uk and euro cars if it is beneficial to the engine or is it a case of marketing to see what kind of reaction it would get along with the ploy that it actually does something.

Whats FFS is that you cannot answer the question, i thought thats what this board was all about sharing knowledge. I have read the thread and noone can say why there is a scoop - can u.

Thats all I want to know and if there is no answer I'm sure that one will come eventually or never at all. As long as my J spec TT6 is going to run fine then I'm happy.

Someone else raised the question and noone could answer it, I have done some rearch to try and find an answer, whats with your attitude problem.

Sorry but the way you keep saying, "but why, but why"...it just comes across as you want to be spoon fed. If you're not happy with any suggestion and I expect it's an amalgam of all answers....then you'll have to find out from yourself from the source.

I thought thats what the forum was for, help from people in the know. Anyway thanks, I'm sure I will be after more spoon feeding when I get the car

I have the answer! The UK models have a bonnet scoop just because they are a better, superior car (not *** one's though, obviously) than jspec or even US ones and deserve that little bit extra.

 

There simple, glad I could help.

Im Going to call Mr T (no not that one ) and try and find the proper answer seeing as i raised the question , i will get back to you with my findings .

 

I hope you can speak Japanese, as no one from Toyota Europe will be able to tell you, as the car was designed and manufactured in Japan, no one in Europe would of been involved in the cars design, they would "possibly" of been involved in the logistics of shipping them to Europe, but they will not know why the car had or didn't have the scoop.

Excuse me stewardess, I speak jive... I mean Japanese. Nihongo ga wakarimasen, desho? I gave you the answers earlier, if you don't believe me, call Toyota of Japan! Most of the customer service people speak Engrish there. End of story.

 

:woot:

 

:thanks:
