As said the base map we nicked for it came from a 472 hp car done on a super flow
and iv also already said they arnt std greys they are big spray pattern ones ..
Weve flowed a set of these before and seen 620 cc so do the math,its capable of 490 hp at 100 duty and these are running 95 % so there you go...

sarcasm is a funny thing!!

M8 its way way above my head, im sure Danny or Jimbo will fill us in.

Power is the key to a powerful car.

Power is a function of torque anyway

 

It has 480 lb ft of tourque and follows the hp line untill around the 4.7k mark then drops away a bit,look at the right hand scale and read its way higher than the left scale..
Also it looks a little lazy but again look at the scale on the right it has more torque than a std cossie at 4.2k and climbs by double that by 4.6k so pretty mental!!!It still has 370 lb ft at 6.4k!!!


cheers danny

 

Correct power is an equation of torque!!

cheers danny

 

i thought it was torque that got you away quicker?

 

im not trying to be funny bud !
just saying what a set of greys do on our dyno

the only greys i know of are the ground nozzle ones that are around a 12degree spray, if they are them i bet it drives horridly ?

as said, power is just torque x revs / a konstant, being 5252

this is the point in which torque and power cross

the longer you can keep that torque up across the revs the more power basically

 

Motorbike/F1 car, tiny torque compared to power but revs like fook and makes power at high rpm

Diesel, low rpm huge torque comparatively shit slow

 

It is the 12 degree ones and they are fine once mapped properly ..

cheers danny

 

Great result folks, looking at the graph i can imagine it to be a handful on the road

I have to say i feel for EP as they seem to go out of there way to help & advice people on here but continue to get slated for it

 

When you look from 4k-4.6k it jumps 220bhp, i bet that gives you a big kick up the arse lol,

I dont think you could find a better bunch of guys than those at EP, and why on here everyone has to keep on with the slating is beyond belief

On a plus side if my car comes with a graph like that and drives as mental as it would suggest i will be more than happy with it

Any one for a big No11 lol

Steve

 

Made very good power for greys and supposed standard head. Hurry up and blow the box and make it 2wd lol

 

They are very friendly and helpful

Steve

 

What boost control is being used on the car?

 

nice power!

 

Nice result that Lee, you saving for the transmission now mate

 

Fair play if its right its right well done & if the car feels better

 

i couldnt agree more with you chris ,danny is ever present on here with advice and going by that vid of his escos at coombe ,he can make cossies go very well indeed

hope you enjoy the car now lee/sarah,must go well

 

hey mate, been thinking about it, what fuel pressure you run

 

dan is away for the weekend now mate .. 3.3 bar on vac obviously rising on boost..

 

to be honest it doesn't matter what e.p do they get slated.

so if your good at what you do and get that bit extra you get slated, if your average you get respect, doesn't make a lot of sense and you won't meet a nicer bunch of guys.

iv used e.p and im more than happy at what they do and as said worth the journey as they don't rip you off with labour charges etc.

Pete

 

wow how good is that figure. I hope your well happy with it now.

 

ok so near standard slightly lower

see ive now got it in my head , and today had to flow a injector of 12 degree spray against the normal grey

quite interesting in what i found thought it might be good for you to see


standard 52 psi static fuel pressure



the two spray patterns



automatic injector drive simulator



the two mid flow test



and the end result which are within 1 cc !




thought it might interest danny as to my findings,

 

Jimbo can you tell the lesser educated mere mortals here what the findings mean? I'm guessing as they dont flow anything drastically more than a standard set of greys that theres no way in hell that car will make 480?

 

all that tells us is that the greys both flow 73 cc over a set program being identical, not saying they didnt see 480 on the rollers just saying that the two greys flow the same

 

the spay on the right hand injector is shit imo.

 

the spray on the righthand injectoris very goodfor certain applications

 

isnt it better the spray pattern ie left injector the better the power and driveability??? light blues have a nice pattern dont they??

 

the left injector is better for driability and equal on power to the left

the right injector is good for set ups where the injector is far from the valve

 

you mean the right injector is jim



sheesh




beef

 

least you know what i mean

 

ill keep you on the straight n narrow fellow !!!

 

show's what i know lol, but wouldnt it cause pooling ? i would of thought the left would be better for that as it mix better in the air flow on its way down to the valve?

 

nice lab test jim but its a well known fact the 2 sets of greys dont flow more just one set atomize better than the other , so you had to do all this to prove a point Jimbo your young you should be out shagging rather than this

thats out of this world power for greys and a standard head

 

yeah you are right but like i say if a injector is far away from the trumpet then the big spray pattern can actually miss the trumpet with a fair bit of fuel and you end up with fuel in the inlet manifold, hence you have the straight injectors for inlets with this set up

its rare people use them but theyre there if people do

ahaha

 

That was a cool test and shows how different they are,theres also a 3rd grey injector too but i dont know what it does if any thing better than these???
That test was done at a static std pressure the big spray pattern injector will cc more than the std one as the pressure rises ie on boost..
Id like to see the test done again at say 4.8-5.2 bar and then see the differnce as when joe done this same test before on the same machine as jimbo has used theres was a bit more difference...
Im no expert on this just know what works but its also very important to have a good fuel flow,so uprated fuel system tweaked fuel pressure = more cc from the injector..
Tell me your opinions on this jim???


cheers danny

 

i thought it was quite good too

true i didnt do a higher pressure test although i will do as theyre in the tester,

 

Before i gave my engine a freshen up and on its first build i had a set of indy car orange injectors on my secondary rail because they were such a nice mist type pattern and cc alot and i can quite honestly say they are horrid on a yb and the 55lbers are much better,i thought it might just be because they were so big but iv put them in a monster evo and they are horrid in that to so yes the harsher pattern seems better in some applications..
It also depends on how good you management is too as on my f88 rs and others the 720 sync and batch firing changes the way the fuelling works too..

Id like to put some 83lbers in dickos engine to see what more power is there because we ran out of injector duty at 2 bar boost so still more in ther and like iv already said cant see how its std as thought!!


cheers danny

 

Rolling rd is a diagnostic tool only the owner can show whatever power they want aswell.
But aslong as car goes well thats all that matters. These tuners seem sound though even though that car is NOT that bhp.

 

Phil as usual you are wrong!!!!
a dd rr calculates power in the same way as a bench dyno does and is very accurate..

We dont fiddle the power figs and every run has its own code so can be verified as this run has been..

Do what you sometimes do and have a read about dd rrs and learn something..


cheers danny
