Nitrous isnt just useful for its cooling effect, see this months fast ford for more info in the "N is for nitrous" section

dovboy

but it is used for its cooling effect as well as other things

Chip

Its cooling effect is best described as a useful side effect.

dovboy

oh ffs,ok then have u noticed phil on a very cold night that a turbo car especially ,goes better?

Chip

iTrader: (3)

Did you just use the word "Phil" in a sentance about noticing something for himself, not repeating someone he thinks he understood?

Surely not

dovboy

rapidcossie

Rich...we cant keep the air box cool never mind a cone

rapidcossie

the air box only becomes a restiction at a certain power level.

99% of people on here are not at that power.

Rod uses a cone beacuse he is WAY past it. Rods inner wing is cut out and the filter area is totally sealed when the bonnet is shut

It has ben tested and res tested on my car.

Garage19

Phil,

Have you never seen an EGT gauge before?

Do you not think the AFR would have more of an effect on the burn temp than the intake charge temp??

rapidcossie

No..i still get the chatter noise but its no where near as loud.

dovboy

euan ,my plan was to put an alloy shield up to block the cone away from heat sorces.

thought about then gold plating it as i have heard that gold is good at reflecting heat.
(air in through the inside twin headlight)
good idea? i'm allways thinking of pish like this that might or might not work

rapidcossie

Again just for the people that think a cone cant suck cold air while the car is moving...

The side of my airbox is actuaually melted from the air that surrounds it.

This proves that the air surrounding your cone is VERY hot.

We have tested all this on my car.

i'm going to put mine back on.....my pal has found it in his garage.......cant do any scientific test........ but will see how it feels....hope it dosn't feel better.........like the cone noise.....

Seems like a harsh thing to say about the old cunt

Euan.........do u think the size of ur turbo makes a difference......smaller turbo,less heat.........

...wannabe tuners its not hard to understand that 40c is the best temp for fuel atomisation..and i thought you was knowledgable..especially you Chip

Chip

iTrader: (3)

Phil, you are correct its not hard to see that 40 degrees is good from that point of view.
Its just harder for the rest of us to TOTALLY IGNORE the rest of the picture with regards to air density and detonation characteristics that a change in temp also effects.

You hear one little fact, stick you blinkers on, and ignore all the other aspects.

big_wig_074

odd,and im not arguing with anyone here,but i changed from a cone filter to my old airbox one day (as i beleived the hype about heat soak.)with the 400bhp engine and the damn thing wouldnt run right,PROPERLY restricted!!!it felt like it was hitting a brick wall.all i changed was the airbox.as soon as the cone went back on it flew again. was like hitting fuel cut as soon as the boost cut in etc,just not as harsh.

...chip i know mucho about every aspect of the YB and here i was stating one fact..ignore the other factors around it the point is i was RIGHT and yet you choose to argue

Stavros

Phil, your wrong.

About your YB tuning knowlege AND this.

Im never sure if you really believe you know everything or just go on an on like this just to wind people up.

I guess both.

An engine builder and a tuner are two wildly different things.

And you are neither it seems.

Mike Rainbird

I think you will find that is from when you slow back down to sensible speeds and the airflow is reduced, but the turbo is still recovering from being at 850°C . The radiated heat in this scenario is absolutely IMMENSE.

Franco

iTrader: (2)

Sod this Phil, Answer ya pm's!!

Chip

iTrader: (3)

No Phil, you arent right, becuase when deciding on what will make the most power on a YB or any other engine you cant just choose to ignore a load of factors.

The fuel mix will be even better at 100 degrees than at 40, so do you think that will give yet more power?

In fact why dont you go even further and route your exhaust through the intercooler, that will REALLY get that fuel to avoid dropping out!

foreigneRS

this thread is brilliant

Bullett

i see this is gonna be a big divide between people.and it always will
oh well heres the front of mine with the morette out of the way.
the big holes go all the way up the underside of the box but not on the turbo side.

Deleted by Request

...........40c is where its optimum....nothing more to say.


Stavros a special shout out to you as i hear you write articles...i just hope they aint technical as you certainly know less than me Judging by your recent replies on here?...Lets hope its me thats the Dreamer Steven

big_wig_074

phil: 40 degrees is the optimum temp for what though?the air?the fuel?at what point?as the air will be different temps before turbo,in turbo,after turbo,in intercooler,in plenum,in engine with valves open,in engine as its being compressed,in engine as it has been compressed.im not arguing,genuinely interested in at what point you need this 40 degrees?

FUEL ATOMISATION

big_wig_074

that doesnt answer my question phil.i dont know the answer so i asked.

CossieRich

iTrader: (1)

so why is fuel atomisation better at 40c than 35c?

foreigneRS

if the fuel doesn't atomise at less than 40 deg. C then you have shit injectors

even if it is the best for fuel atomisation, it doesn't mean it's best for power. if all of the fuel doesn't atomise to get a burn with the 'best' AFR to get most power, you would just inject more fuel until it does

how difficult is it to understand that the more air you get in a cylinder fill, the more fuel you can put with it to get the most energy out?

quite simply, colder air is more dense and has more oxygen per volume (which is the limiting factor in an air pump) than hotter air. that is simple physics and cannot be seriously argued against other than by a total clown.

and that is ignoring any effect on reduced detonation risk of lower ACT's that may allow better ignition timing for more power

i don't know why any of us are wasting our time typing really - god has spoken

you're such a cunt cos i never know when you're serious or not

capri-rs

have to say. this is the best topic i have started so far

rapidcossie

it will work a treat Dov as thats what i have now..not gold tho

rapidcossie

he may be old but wouldnt say he was past it

rapidcossie

i did notice a increase in under bonnet temps after i fitted the T4.

so to sum this one up a 90qwid group A filter is a waste of money and just modifi your standed airbox

anyone want to buy a new group a filter cheap or will px for standed airbox
