Bristol group RSOC rolling road shoot out today at powerstation no stage 3 cosy made over 300BHP

almost all the cosys were 40/50bhp down on there figures

last time mine made 320bhp(hot summer day) about 1000 miles ago

since then all i fitted was a Proalloy RS500 cooler(more power) damp cold raining nov day and now the figure was 284bhp almost 40 bhp down.

Why are rolling roads so fooked up

Jimboxr4x4

Was that at the wheels though?

DOO

both engine bhp out put.

Chris Honeywell

Thats powerstation for you m8 that why i stayed worked rather than drive up there
they figures are always wild..
Remeber last year they had daves on the rollers and after running it up to 2bar boost they decided that only 4 of his 8 dark greens were working and would not run it again..
needless to say all 8 were working

DOO

TBH mate i wish i stayed in bed

All the cars where well down on power


Also had the cars on and off in min`s just all rushed IMO used to give the cars 2 or 3 runs one run and that was it today
TBH i don`t think they can be fooked with the good old cossys now a days there well into there scoobys now. shame really

St3V3_C

Funny I've put a 500 cooler on and lost 45hp as well

Don't worry about it mate - it's only a bit of fun, and I still beat you


*/ducks to avoid flying shoe

DOO

Never mind mate you win


Prob have less power soon when i fit the baby turbo back on

Rhys

Shame they didnt put CO meter in etc as i would have like to have seen that on if my car was on the rollers etc.

St3V3_C

I think Simon did say they would if you wanted, I wasn't too bothered - if there was something wrong I would have blown it up long ago

DOO don't do it - get a t34

DOO

Never mind it would all be printed for the world to see(FAST FORD MAG) how shite are cars are not how shite the rollers are

Rhys you right mate only did not see them use the co meter once

DOO

I don`t want the lag mate and want to a small turbo back on like it`s meant to have.

Got a new T28 hybrid 360 bearing waiting to be bolted on then a live map set up etc..

Stavros

Powerstations rollers have always been totaly bizzare and rushed, like the rest of their work They seem to guess a lot of things with no basis for their thoughts, like the 4/8 inj thing that was mentioned.

I had a nice lie in, then did some work on my car, then aranged tonights and 2moro nights drinking/birds plans.

And did the washing up

MarkTurbo

I went to a Gti-R owners club rolling road day there earlier this year and it was exactly the same

I doubt any of the cars spent more than 5 mins on the rollers and even with about 20 cars there it was all over in no time

Powerstations rollers are well known for being a bit on the conservative side as far as power readings go anyway

Ooops

Glad I stayed in bed then.......lol

Rolling roads are only good at estimating power they are inherantly
inaccurate due to losses through the transmission/tyres/tyre pressure/clutch etc.
Only comparisons on the same day at the same enviromental conditions should be
used (good for setting a car up as you make adjustments).
Also, BHP power correction needs to measure humidity, ambient air pressure,
ambient temperature and accurate RPM measurement (via ignition pickup).
Hardly ANY rolling road I know off has ALL these facilities if any at all.

What is consistant about todays results is that all similar power cars are
down on power which kind off backs up what I am saying.

Stavros

RRdays are bollocks, facto, mainly for the reasons mentioned above, total guesswork, esp flywheel fiugres.
If people wanna prove how quick there car is a group day at a RWYB would be far better, and more fun too.

That said, some RRs are more consistant than others, but Powerstations ones have always always been incredibly inconsistant.

DOO

Thats sounds better mate RWYB group day any ideas on price for the day morning or afternoon any other places the more local the better.

Or is it just santa pod.

Stavros

Shakespear County raceway on way to Stratford from Cheltenham, i prefer it to Santapod actually for the track etc, about 20min drive from Chelt.

Cant remember prices off top of head but less than 20quid for unlimited runs on a RWYB, and you will get LOADS of runs too, as many as you like, unlike Santapod RWYBs where it so busy youl be lucky to get more than 3 runs.

Need a helmet for 100mph+ terminals.

Santapods not too far tho, 1.5hr from Chelt, so only 2ish from Bristol, but ShakespearCounty is better IMO.

RANJ

wasnt there a claimed 600hp car went home with 348 or summit

Fagin

If you want a high figure go to Power Engineering.... if you want a lower figure go to Powerstation. TBH I will stick with an under reading any day of the week.

Steve,
Thats funny as PS seem to have the same impression about you as well!!!

Simon,
To correct figures to DIN 70020 requires exactly what you have stated. Unfortunately the rollers at PS have this, but the extrenal box that takes all the readings is mullered hence why there BHP @ Flywheel figures are uncorrected.

DOO

there was a claimed 600hp car there but don`t know much about the spec


adi car was there MAD altronics gt28 etc.. flint grey sapp should of been well over 500bhp was 440 on the rollers.

Stavros

Only person i know from PS is Curtis, AKA Penfold, and hes well known for being king billy liar of the town, and he looks like Dangermouses Sidekick, so does anything he say hold any relevence in the world? No, exactly

gurnE

I think the thick layer of rubber the thing left on the rollers was the reason for that reading tho

Even with 2 peeps on back seat and 3 in the boot

Fagin

My car was a claimed 1000bhp (according to the laws of IMA), but I only achieved just over 500bhp on PS rollers.

Steve,

DOO

you should of ate thoses 1lb burgers before the shootout he might of got some grip then

RS Bowk

glad i didnt put my car on in the end as they jus didnt seem 2 care 2day jus seemed like they wanted 2 go home 4 there diner!!

but hey it was a day out!

rs_daz

Yeh it was abit rushed today ,was a good laugh tho

That r5gtt :
Pissin water and oil out after the run.

who was that guy wiv the red jacket on calling the next cars?? pmsl when he shouted get that thing out the unit! its fucked lol

mates RST made 160bhp there on wednesday on 7psi, and all thats got is a piper T285 cam and a shitty pace I/C must be a "randomator" correction figure going on

DOO

Glad it was not just me who thought it was rushed etc..

Steven_RW

Why not just go with the wheel figures and compare car against car on the day.

If a car wheelspins it OVER reads not under reads. The rollers have a set resistance on an accelerator style test and the engine rpms are measured by the computer and if they raise really quickly the r/r believes the car has loads of power to accel that load figure so quickly.

Thats why accelerator tests on a rolling road result in innaccurate figures.

A nice loaded up figure, up at 500 rpm intervals or 1000rpm intervals and held against the rollers at those rpms tends to give a steady figure.

RW

gurnE

Engine RPM wasn't measured.

They were just being slung on and run up.

Not even monitoring fuelling

Steven_RW

Gurne,

sounds like a pro job then!

How did the wheel figures compare with what people expected?

RW

Stavros

That 442bhp car, looks like its got a small turbo escos inlet and a smallish internal wastegate GT series on it, so couldnt see it ever being over 500bhp, no way the 600bhp mentioned, so i dont see whats THAT wrong with a 442bhp reading myself as very few "500bhp" cars get near that on the rollers.

PowerStation flywheel figures have always been really really inconsistant, dunno about wheel figures mind

rs_daz

Didnt even seem the cars were warmed up well.and i only saw that fuel monitor unit used on 1 car the s2 wiv yellow bonnet vents

B19-TRB

steve it sruns the eco tech throttle body correct as it is larger!

its a gt30 internal wategate turbo aswell!

Mr Shead dyno'd 1 the same with less boost than ade rusn 7 it made 521hp! so ade's should be aorund the 530 mark!

the 600hp car that Ranj was talkin about was not supose to be 600 lol!

but it did run a GT35 & external wastegate same setup as what daves had i beleiev when he made 550hp

St3V3_C

Which one was that? I didn't see it - must have been outside.

B19-TRB

moonstone 1!

the 1 with the subs in the boot lid!

St3V3_C

Ohhh, I did see the car.
