if 40 deg. C is ideal, why is there not some sort of heater for cold days?

think stavros summed it up nicely by calling you a clown

Deleted by Request

Mate its not me you are calling a clown


..but i do accept it aswell

Its not my fault the internet is full of spaccos as Stavro puts it

Garage19

Really???? Where did you get that gem from?

i always thought the colder the air the better, as cold air is more dense. the hotter the air, the harder it is to combust? Is that right or wrong?

So by my reasoning, if the air charge is 30 deg c, thats better for power?

Do you have an intercooler before the turbo as well then Phil, or do you think it makes no difference to the turbo if its sucking in hot air?

CossieRich

iTrader: (1)

i expect he got it from the fact that most cossies are set to trigger water injection (if you have it of course) at the 40c mark?

i put a cone on my saff when i first got my saff and it made it feel unresponsive to me.im an airbox fan myself.i have mine drilled at the lower section of the front and up the underneath where it sits on the inner wing,plus i have the centre light out of my quads for airflow.

plus if cones are so good why didnt the 500odd bhp touring cars run them?
and i much prefer the look in the engine bay of the box

Phil,
APMSLOL at your comments. Obviously Euan's 30bhp gain when ditching his cone for an airbox was a figment of his imagination .

I measure underbonnet temps and in high ambients, you wouldn't believe what they climb to (on track) . Obviously a cone would be ideal for you, as the noise and the fact that you never work you cars hard would mean you wouldn't notice the loss of 30bhp .

Thats right Rich............. But i'm just a shipping manager!

Stavros

Because ABOVE that is BAD, below that is acceptable enough to not need to go to big efforts like WI.
Remember, this info is coming from GrpA/WRC Escorts, and its a trade off between weight and power, if they injected water below 40degC theyd need a MASSIVE tank, so the decent comprimise was 40degC.

But 10deg is WAY better than 40deg in reality.

Unless you listen to the expert there

Cossierich, the issue is that if the charge temps drop too low you can start getting issues with fuel dropping out (ie condensing)

But Phil is of course spouting shit about 40 degrees being the mythical perfect figure.

Bullett

iTrader: (2)

exactly rich,the more dense the air the more fuel you can burn which in turn means more power.

CossieRich

iTrader: (1)

Chip,

how low do you have to go before fuel starts condensing or are we talking the north pole sort of temps well into minus figures lol

Rick

childish question - does chatter totally dissapear when you run an airbox?

COSSIE CAL

soall round its best to run a standard box?

Stavros

The "too low" temps are proper north pole spec, actually they are impossible on a turbo car really considering the heat a turbo puts into the inlet charge.

No, tho it does a good job of muffling it.

Franco

iTrader: (2)

Oh Rainbirds going to love answering that one!

Bullett

iTrader: (2)

nope,especially with the recirculating cuntvalve out.

Chip

iTrader: (3)

It varies depending on the AFR you are running and the design of the inlet.

And also if you are looking for optiumum for economy or optimum for performance.

40 degrees or more is a good place to be from an economy point of view in most instances, but I cant imagine any car will make max power at that temp.



Its a very very complicated subject, as the heat of the charge effects the burn rate, which in turn effects how advanced it can be iginition wise before seeing det, which then effects where you can position the PCP in the cycle etc, seriously you could write a PHD on a small part of the subject of intake temps!
(and I couldnt, hence im not going to try and name numbers, lol)

But 40 on a YB is definately a load of shite for optimum power, its way lower than that im positive, so ive no idea why Phil is quoting it, unless for some dum reason he really believes that!


Compression ratio also effects the amount of heat you want to see or not, so if you combine that into the equation Phil can probably come up with something so innacurate it risks putting the planet out of orbit as a result of the enormous wave of stupidity rippling out from everyone's screens

Micky The Finn

nope,you want to here mine when being used to its potential,sounds strange but even with a peltor on you can here it chipring away to itself.

Deleted by Request

As said its not from ME..but from a proper pro I bet it really irritates the book worms i am blessed with such knowledge...40c is where its at for optimum power on a YB.

Whats your view on this Mike as you know the person who told me

Chip

iTrader: (3)

Yes Phil, thats right, 40 degrees no matter what turbo is fitted, no matter what boost its running, irrelevant of cmpression ratio and nothing to do with what AFR its running.

They ALL work best at 40


You didnt misunderstand anyone at all, physics really is that simple

Deleted by Request

What on Earth are you banging on about Chip?...if you can get 40c air charge temps no matter what spec you will have the optimum burn...so please stay off the books.

Chip

iTrader: (3)

Phil, you really do believe that you have understood that correctly dont you?

Deleted by Request

...who cares...its still 40c.....its also the best temperature to wash your clothes at

Mike your very quiet?

Chip

iTrader: (3)

Even that varies phil, depends if they are colour fast or white etc

Best Airbox I've seen was the works one I got from Tim Finch

Which was a carbon lid with 70mm outlet on a modifed Sierra sized base



Hows that for air flow




But was no good to me as I had standard headlights so I modified another sierra base to take the original Esc Cos feeder pipe drawing from behind the foglight grill



My question is what benefit would I have to having a hole cut in the box behind the standard headlight? I can't see how it would get any airflow? I can understand the morrette users with the ducts

Mate you never read.. you must just look at the pictures

No i have to work as well as read!!

So yes i just look at pictures!!

Undoubtably amhed is a wealth of valuable info.

Also undisputed though is that Phil trying to repeat him ISNT

Ha

We should write that!

if its 40 deg,why bother with nos
