dingy

how is that.

rapidcossie

I always thought that DD fly figs are pretty high for the spec from what I have seen but even if its 450 ish you have to be happy

dave cos4x4

iTrader: (5)

rapidcossie

suppose so.

if anyone asks i always say its round about 400 ish,think i will still stick to that.

Dingy

Your car made more power at the wheels mate....

At all 4 wheels....

So what difference does it make if its 4wd.....cause it has more power at the wheels...

Normally 2wd make more at wheels due to less loss's etc....but at the wheels figures are at the wheels figures....so the fact mine is 2wd has no meaning on the arguement....

This just show's me how shite DD rollers are LOL and how mike r reckons they are consistant in power readings LOL....


Like i said PUB talk

Bugger guess i am Due one of these then

You doing Daddy thrash or Retro Thrash mate?

OldDan

I guess 477 at the fly

Dingy

Not been invited mate.

rapidcossie

Like Dingy says RR figs aint anything to hang your heart on, just a bit of fun and sometimes useful to help develope things

Cams and fancy head and some 1000cc injectors next

dingy

got ya, mine would of have had more trans losses that all.

shame about the daddy thrash Steve.

Nash

iTrader: (3)

Any idea why? You not been dipping you wick where you shouldnt have, have you?

Dingy

Whats that meant to mean ?

dave cos4x4

iTrader: (5)

who needs them.

don't want to go that far with it Euan.

its ok the way it is,not much to fix when things go wrong aswell.

Nash

iTrader: (3)

Nothing was a joke bud. Just ment you aint been rocking on of the editors missus world have you, and thats why not invited.

Dingy

Seems a bit of an odd statement to me

3i_gaz

was a bit petrol starved

still goes round corners jsut as fast dave, must be the driver eh

Nash

dingy
No one said i was normal mate.

Just cant understand why you not been invited to the Retro Ford one especially when it must be one of the fastest MK2's.

Gatecrasher

I was always lead to believe that Greys would top out at 440HP is this at the wheels or fly then?

Nice result for you Dave well done

dave cos4x4

iTrader: (5)

3i_gaz

corners are where it matters.



Gatecrasher

i thought that too,but as the graph shows,it was very lean at the top for the afr,hence a bit more power.

well....thats all i can come up with.

Charlie Chalk

Im gonna need a power increase soon to keep up with you lot, Track wont be no fun on my own

Thought this was next week. Only 15 mins away from me too

Good result though Dave

Butch.

iTrader: (1)

great result there dave

Fiecos Dan

good bhp / wheel for spec.



have you got the boost graph?



Who mapped it? as fueling isn't good at all in the mid range. (top end must be the inj's maxxed out.)

dave cos4x4

iTrader: (5)

Butch.

thanks mate.

Fiecos Dan

Dan, the boost map is what you would of been looking at if you noticed the fuelling,its next to it

Mark Shead

Dave

Heres my observations on the graph,
The Intake temp has over corrected this is a typical dyno dynamics action they say place the temp prob in the airfilter but this makes it correct upward, I tested this a while ago and 15c added 2.5% to the total power yours has corrected 42c so the correction is very large,
On the lambda reading sometimes this can be wrong if they have used a short pipe in the tail pipe and you have a small baffle tube in the back box then pulls in air which then will show lean, This could be your problem but I would get this checked,
This is not a dig just a highlight of what I have found using these rollers.

Mark

Karl

Dan, I mapped it.

Dave, you need to turn the boost down or get it back to me for a check up. The AFR is too rich midrange and leaning off quickly at top end. This indicates to me that you are running over the 3 bar map sensor threshold.

For now make sure its holding no more than around 28psi, but I'd advise another check over since you've had the turbo rebuilt.

Fiecos Dan

, didn't even look at that plot, doh.

Fiecos Dan

time for a 5bar.

dave cos4x4

iTrader: (5)

Mark Shead

can you put that in English Mark.

Karl,

i will turn it down and get it checked over

Staffi

iTrader: (1)

Alright Dave

dave cos4x4

iTrader: (5)

Don't 'Alright Dave' me!!



YOU...its all your fault.

Mark Shead

They are great Rollers but the way you are told to run them is place the air temp probe in the air filter so it measures intake temp and corrects the power,
But in practice this gives engines with hot air intake more power but in practice this is not the case as the temp should be corrected for cell temp not air filter temp,
Whenever I run on these RR I have the air temp probe hanging in the cell so it corrects for cell temp.

Mark

Mark Shead

still 'no comprehenday Mark'



have i got 400 bhp,that will do me.

Mark Shead

I would say a easy yes above 400hp and looking at the boost graph you do need the fueling sorting and boost .

Mark

Mark Shead

Easy way to explain you dont have 477hp but you do have a lot anyway .

Mark

kev 3dr

iTrader: (1)

Well done Dave nice figures

dave cos4x4

iTrader: (5)

no shit Mark.


i think everyone knows that is highly unlikely with my spec lol.

is 400 a lot lol.

Staffi

iTrader: (1)

So, hold on then, if yours is wrong Dave, that makes the Evos all wrong aswell..

Karl

Dave,

Seriously Dave, from mapping your car and knowing that the engine can out run the greys when running over 28psi, I think a good estimate of engine power is around 420bhp @ 28psi.

Unless its an error in the exhaust sampling, the AFR is leaning off quickly as the revs rise, indicating that you have reached the maximum duration time of the greys. As said for now turn the boost down to no higher than 28psi, as this is the maximum I was able to map the car to. Above 28psi it started to lean off after 5500rpm.

If you're interested I can simply remap the car on some 750cc injectors and a 5 bar map sensor if you want to ensure reliability at higher boost levels.

dave cos4x4

iTrader: (5)

don't you even go there Pete.

go on MLR and tell them.

Mark Shead

Pete

You will find the evo's have a slightly better airfilter postion and the temp wont be as high so the correction wont be, But you can see this on the graph.

Mark
