Will have a look later... you not get any footage of anyone else then? how rude...

good results there though, looking forward to the rematch with the chuckle brothers :lol:

no martin did everyone else..i only had a 32meg card to record onto. its full after 5mins.

Good vids mate. You sure yours aint had a re-map Northy? It went past the limiter again :wink:

northy
13-02-2006, 15:07
nope.... :D tbh most were going past the limiter.

andys and fatboys for definate.

I will be able to see if everyones did when i get the official list.

Andyvalver
13-02-2006, 15:09
:? How can most go past the limiter? Thought that was the point of it lol.
Is there something your not telling us :wink: Youve got a gunner chip havnt you :roll: lol

J o n
13-02-2006, 15:09
pah, you cheat... so that's how you keep up... :roll:

northy
13-02-2006, 15:14
well it only happens once the engine is warm.

On the way down andy had a quick play with me

4th gear around 65mph - we both accelerated at the same time and there was nothing in it untill i hit the limiter (never saw it approaching) changed into 5th and andy kept on and pulled a car length straight away, then he changed into 5th and the gap stayed the same.

i got a text off him saying that he changed at 6900rpm. mine came in at 6500rpm.

So its mad. They were both warm - but certain gears the limiter does change.
Ive discovered to change on the first nudge of the limiter now rather than looking down at the dashboard for the 6500 limit.

J o n

hmm, so both the Northrops are running none std ECU's then... thought your kids was a std quickun? :wink:

northy
13-02-2006, 15:59
andys well beat my on the torque in the low rev range, but at the top end mine panned his

andy needs to get a cat back on to unleash the bhp.

Andyvalver
13-02-2006, 16:03
andy needs to get a cat back on to unleash the bhp.

Is that right^^^. Do you mean a de-cat?

northy
13-02-2006, 16:05
yes.

he has a decat - but he still has the original exhaust from the cat back.

a custom one will see some good gains.

I want a williams :cry:

J o n

no, I think he needs to drive it to unleash the BHP... :roll:

13-02-2006, 18:29
have a word with him Richy, you weren't this bad and he used to rip you all the time for it... he's missing out by not driving it and it will lose power just stood all the time

i wanna watch these but they wont load enuf, it plays for aboot 1 second then starts buffering again :(

Martin

Andy's made 122.8 corrected not 121 ...

northy
14-02-2006, 15:06
still impressive for only a decatted car.

J o n
14-02-2006, 16:52

less than std power ATF that mate :shock: i make it 147bhp... doesn't sound right at all that

northy
14-02-2006, 16:57
dont forget that corrected jesus. Nicks machine was set to 15% correction.

have you watched the full footage yet ? its on there what it made.

J o n
14-02-2006, 17:32
eh? what is correction then??? and why do you have both figures? which is the meaningful one in other words??? i just want a RR of how powerful the car is when mines done again, not bothered about all this ran 130, but if it was Wednesday it would have run 200... :lol:

northy
14-02-2006, 17:39
there was two readings.

A. the result on the day
B. the result with a correction added to get a 100% correct base. (so no matter when the car is next run, aslong as that same correction is entered u will get a same result regardless of weather)

The lower readings are the ones i would use jesus as they match up with RE and MiniSport.

J o n
14-02-2006, 18:00
i still dont get it, if it's accurate why have a corrected figure? it's meaningless by the sounds of it :?

northy
14-02-2006, 18:01
the correction is to level out any variances weather may have.

if its red hot one day u run the car - the readings will be low.
if its sub zero the readings will be high.


if u run the car corrected - it doesnt matter when its run. the results will always be the same. Think of it like a level playing field.

J o n
14-02-2006, 18:05
see what you mean, but if its a cold day why are the figs going up? :?

think i'll not bother getting my car RR'd, the figures make no sense to me and no one is able to just explain it all. it seems illogical that on a cold as feck day you can correct figures upwards... how much colder can this country get ffs? pmsl

northy
14-02-2006, 18:09
the colder it is the better the engine can breath. its a bit like N2O on a car thats really cold. cold air equals BHP.

hot air takes bhp away.

Think of a induction kit in the summer. its red hot and your in a tail back. once it clears u accerate but the engines pulling in hot air and u have flat spots.
if it was sub zero - the car will fly.

the corrected readings give a set temp for air and the results are worked out accordingly.

This is a northy way of explaining it. Nick Hill or Ben R will know what im on about heehee and will probally do a better job than me.

J o n
14-02-2006, 18:23
all that is what I thought, what I'm confused by is the OBS power thing... is that corrected or is the other figure corrected???

MatBrown
15-02-2006, 02:24
The Observed figure is what the car achieved on the day, the other figure is corrected so that the car can be compared on different days.



Mat.

J o n
15-02-2006, 10:02
gotcha, i'd have thought that would be the figure to go by then, the corrected sounds like a worse case scenario?

stew
15-02-2006, 11:39
Im confused also!

If you take 15% off the observed reading for the corrected power, then each and every time it will give a reading 15% lower no matter what roller, if its hot or cold etc. Seems random..... :?

If all rollers are corrected by say 15% then they will still surely be differences in the power from one to another.

2 live
15-02-2006, 12:05
but wont the corrected figure, if worked out as a % or worked out from the readings of teh day, change again if the weathers diff?? so no point in the corrected ?

i.e on day it runs 120 bhp, corrected it runs 115 say, how is this worked out?? if its a percentage, the corrected figure means jack, as its a percentage of the figure read that day, which will vary between days, so the percentages will be diff.

northy
15-02-2006, 12:12
no idea.

ive asked nick to answer your questions lol

2 live
15-02-2006, 12:35
cheers



jus hope he can help clear the misunderstandings up.



oh and btw. were the rollers calibrated b4 and after each run, and all the calibration equipment callibrated b4 and after each use as stromba says they are and shud be??

northy
15-02-2006, 12:40
no idea....nick had been walking around on his feet all day and his trainers might have gone out of calibration since he had fitted them in the morning heehee

having all the cars in one place and run the same day is a very accurate way of measuring the power....the resuslts match minisport and re jon so u know there settups.

I have a live recording of my run coming from nick - hopefully i can post it up here for u all to admire.

MatBrown
15-02-2006, 12:43
The corrected figure was not just a percentage of the observed figure, it was worked out using the weather station attached to the computer so the actual amount corrected will vary everytime to give you a constant reading whenever you run the car.



Mat.

2 live
15-02-2006, 12:45
lol.....jus curious.



121@ wheels...is wot my old valver put out on minisports r/r, 135-149 willy on re's.


and as for measuring power........how come, on most r/r days weve had, not jus this one....lol.......the power on the rollers isnt always released when on the road?? e.g some cars make more power on the rollers, but are actually slower by quite a margin on the road.

Mat.



so how does the weather station come up with the figure?? surely for this to be precise it should be run in an enclosure??

northy
15-02-2006, 12:48
well take martins, its running 14.1's to 14.3's and has less power than mine running 14.8's - 15's

but thats down to the wait of the car. Mine has all the gay things added to slow it down.

I don't know what programme they are running to calculate the differences.

yes mate i know weight plays a part lol. but in similar weighted cars , i.e fully trimmed williams' can put out 2 diff power outputs on the rollers, but, the lower reading powered one will usually be quicker than the higher reading one. hows this work??

J o n
15-02-2006, 12:59

assuming you mean the driver? :lol: :wink:

15-02-2006, 13:55
jus bin thinkin how much diff the weather will actually make.


usc last year...pod....35 deg heat....runnin in full spec, ran 14.5s on bone dry, sticky track


couple weeks back........runnin down on power, and on a slippy track, but at 13 deg heat or summat, ran 14.8s....spinnin in 1st 2nd 3rd, a bit, and on upchange to 4th


less power....more speed again lol.


so if i could get the way that the r/r calculates the corrected figure, i could work out what mine would run at pod in its old trim but on a cold day. :wink:

so far its lookin like it could be anywhere between 13.0 and 15.4 dependant on weather

Martin
15-02-2006, 14:08
The corrected figure is'nt a % ....mine had quite a large difference between obs & corrected as I was first on the rollers when it might have been slightly cooler..

I ran 131 corrected 148 OBS
Northy 132 corrected 146 OBS

J o n
15-02-2006, 14:12
i dont understand any of it tbh, as long as my number is higher than you lot i'm not arsed :lol:

2 live
15-02-2006, 14:13
so if itd been a really hot day instead of cold........ud be lookin at wot??


131 corrected 114 OBS??

Martin
15-02-2006, 14:15
It is a touch confusing..I don't mind using the lower figure tbh as it seems more realistic to me.....

Martin
15-02-2006, 14:17
so if itd been a really hot day instead of cold........ud be lookin at wot??


131 corrected 114 OBS??

yup although I reckon it would to be r/r'd in the africa or some shit to get a figure that low

2 live
15-02-2006, 14:17
a straight 1 fig at the wheels is good lol.............saves all the confusion.

would be good to know the calcs made tho... if nick ever reads this

Chris n`nic
15-02-2006, 14:19
I think the temp will make a diff but not as much as you`d think....when I got a 14.1 @ York I was running a cone filter and it was 28 degs! I think the advantage of a grippy surface overcomes the disadvantage of the air temp.

Chris

2 live
15-02-2006, 14:26
but my time at pod is only 0.3 secs slower .....1 on slippy as fuk track, 1 on sticky as fuk track....with severe power loss between the 2.....



so ....less power..less traction , 0.3 secs slower........only thing in my favour really was the diff in temp.....surely my cars not nearly as quick as it once was.......i know it isnt thru the driving of it, but the times there would suggest its probably quicker.


strange.

J o n
15-02-2006, 14:30
if it is as quick as it was I'll be running 13's all day long after a remap... so I seriously doubt that!

Martin
15-02-2006, 14:50
I really doubt I'll run such a high terminal speed again on a hot summers day...even with bonnet off to keep it cool....but the incresed grip makes up for that 5 times over...

I like Pie

Martin
15-02-2006, 16:21
wtf lol

J o n
15-02-2006, 16:24
I like Pie

more importantly what kind? i'm not fussed as long as it contains animals and no onions...

FlamingMonkey
15-02-2006, 16:36
Ah I beg to differ I like animals in my pie WITH onions or maybe sometimes WITHOUT onions

Martin
15-02-2006, 16:39
no onions in my pies lads just dead animals & a touch of veg maybe

stew
15-02-2006, 16:47
onions, veg, just chuck it all in!

cant beat a good forfar bridie (famous scottish pasty type thingy for all you ignorant pom's!) :wink: :wink:

its strange mine and northys are dead even on the road

so god only nos

That abs & sunroof must be weighing northy down lol

Tis very weird....i sure as hell would'nt want to guess the quickest cars from r/r results....

Andy
15-02-2006, 18:20
dont care what it says im quicker than him

Martin
15-02-2006, 18:21
lol cat back is your solution to start panning ricky... :wink:

northy
15-02-2006, 18:23
pahh, he needs to try before he buys

think mandys a standard boy lads...heard talks of the cat going back on.

no point in preserving a willy 2 :wink: get it modded mandy :wink:
