Cruisewirral Rolling Road Day



Date : Saturday 5th March 2005

Time : 9:00am

Location : A & I (Peco) Acoustics Ltd
Sandford Street
Birkenhead
Merseyside
CH41 1AZ



The normal cost is £40 + VAT (£47:00) but with a group booking we have managed to reduce the cost to £30:00 in total per car. 20 cars are required to secure the reduced cost.

What do you get for your £30:00 ?

Your vehicle is checked for safety, oil and water levels, tyre conditions and pressures and One power run on the rolling road with a graph power (BHP) and torque printout. Peco's technician will drive your car to the Max to obtain your BHP & Torque figures. He will only rev the engine to what you tell him.

You will be entered into the Cruisewirral League table of results.

This rolling road is only suitable for 2 wheel drive cars.

We require a small deposit of £10 to confirm your booking (Payable in cash to Scooby at Autosafe Garage or Sally at the Cruisewirral Meetings).

Your £10 deposit must be paid at our next meeting at the very latest to confirm your booking (3rd March 2005) and the remainding £20 to be paid on the day.

I will provide everyones standard BHP figures before we go therefore you can compare your standard figure against your actual figure.

Possibly looking at a prize for the most increased BHP figure :go: :go:

How long will this run on for? I work the night on the friday and will be far off in the land of nod at 9am saturday, what's the latest (safely) that I could turn up?

Also, will they give a torque read-out?

It starts at 9:00am and runs until everyone is done. Each car takes approx 20 - 30 mins (20 cars x 20 mins) will finish approx 3:30 pm maybe. Its hard to judge really.

You get a BHP & Torque printout Jimbo

We need one more car peeps, Tonymk2 has dropped out now

Aaawww no.We need more people,not just one,loads. Lets make a day of it lol. What would the price be for 29 cars scoob??And what would the price be for 30 cars??

Im DEFFO comin to this event!!!!

If we got 30 cars attending we could probably reduce the cost by £5.00 per car but i would need to confirm with Peco first ??

I think the CW van will push out approx 68 bhp

What do you think your car will produce ??

well ford state 74 BHP standard.So i think that mine is now 75
(take into account the 57i,cat back,larger pipe all the way back to twin 6x4 ovals with no silencer in the middle then its a tiny gain.The age of the engine would have reduced the standard figure tho and its only been modded for 15000 miles worth.)
Will the RR give a figure close to this or will it be 25% less (which is what i hear rollin roads display as its taken from wheels not the flywheel)

There is a calculation you can make to work out the flywheel BHP from the rolling road figures.

<b>If members wish to post there car details i will reply with BHP figures as standard so you can compare figures on the day

Hopefully will have exhaust fitted by then. I will pass by your place Scoob and drop in the deposit.

Tony : This is only for people attending the rolling road day

Do A&L have a phone number as i need my speedo calibrated and they may be able to do it on there rolling road

im trying 2 get the day off work to come along. i want to have mine tested cos i was told my car is 140bhp even tho all the dealers say they are130. I plan to get the ECU remapped in the future so its handy to know what i have gained.

Will be working i'm afraid but may see if anythings still happening after 3 and pop up too watch.

Suprised everyone who doesn't have comitments aren't up for this, fantastic chance to get the read outs and finally kn your true bhp with all mod's.

The rolling road facility will not be able to calibrate your speedo, however i have a mobile GPS unit that will read your true speed via Global Positioning System 100% accurate matey

BHP 170 : KW 125 @ 5,8000 rpm

===============================

BHP 60 : KW 44 @ 5,000 rpm
Based on 1300cc hcs engine
1600cc CVH varies from 65 - 90 BHP depending on engine number.

===============================

BHP 64 : KW 47 @ 6,000 rpm

No Data Available

Dave, can you attempt to find out the relevant info via your contacts ??

I would love to run mine to see how it is performing as it does not seem quick enough. Cant i turn up and pay on the day as a extra.?

Alias

This event is Pre-Booking only at the moment, however we are one short....

It may be possible for you to pay on the day however it would be the full price of £47.00 instead of the reduced price of £30.00 for our group booking.

It would be great too see you there but you really need to Pre Book in advance with Cruisewirral to get your reduced price

All you have to do is pay the deposit of £10 before friday next week and thats it mate.

Make : Ford
Model : Escort
Year : 1998/99
Engine size : 1.6
Engine number or code : S514 VUK

Should be 90PS which works out @ 88BHP from the 1.6 original standard engine

dazza ive seen 1.6 escort stats that say its 90bhp and others that even say 94bhp.....

90PS = 88BHP fella!
Most Zetec engines are measured like this/

i've heard this from a million and one different places, i've got that engine, know a lot of people with that engine, and thats what they say too

Still looking for one more?

I wouldn't mind attending.

AX_125 Copy and Paste your name into matey, aslong as you can come up trumps with the £10 deposit before Friday

Yeah no probs, I am just checking with the better half if i can come, cant remember if i have plans or not.

Will be interesting to find out the actual figures, parkers says 123, handbook says 127 other sites say 125.

Wont be able to make it now sorry guys n gals

Ax, you would be welcome at this event, would be good for you as several Civic's are attending

You can pay the deposit at Autosafe garage if you want, latest is thursday to confirm the booking.

Cheers mate, i can pop in today, can i pay the full amount today or do i have to pay the rest on the day?

you can make the full payment if you wish, no problem. A minimum £10 deposit is required though.

Another Civic

Scooby, I'll probably come. I'll have to see about work first. I'll speak to you on Thursday.

Rich

Paid up, see you guys there

Make :Honda
Model :Civic
Year :1998 Coupe
Engine size :1.6i SR
Engine number or code : SOHC VTEC

I cant even be a passenger to this, Im too busy with Vicky and Kara that day

I can come, but it's going to be around half 1 before I can get there from work. Will I still get a place?

Rich

To Hold the discounted Price, Deposits are required in advance.

Read over this topic as a simular question has been answered.

But get the deposit paid first is the most important part or you would have to pay Full Price on the Day.

Hope this helps.

I'm going to pay my deposit tonight. I just wasn't sure if there were actually any places left, let alone one that late.

Rich

More the Better

Anyone is welcome Providing there Deposit is Paid up buy Tomorrow at the Latest.

As the Rolling Road is being Booked at Lunch time.

This is an Exclusive Cruisewirral Day at Peco.
Only Deposit paying members can take advantage
of the Discount cruisewirral have secured.

Members need to ensure there deposits are paid in advance, to qualify for this great discount.

Its going to be great Fun

:go: :go:

I have been to Peco today and Wow

They have one tidy little set-up down there

See you all there peeps.....

are we meeting up somewhere first and convoying in?

or just go straight there

Rolling Road Day
Good morning and welcome to everyone from 'Cruisewirral'.

My name is Dave Jones and I look after the Research & Development. department
here at PECO. As such I'll be the one who's going to put your car through its paces
on our rolling road today, promise to treat it gently!
I'm sure a lot of you have been to a rolling road before, but for those of you who
haven't, I've made a few notes to help you understand what it's all about.

What is a Dynamometer?
A dynamometer is a tool used to measure power and torque produced by an engine.
There are basically two types of dyno, an engine dyno and a chassis dyno (rolling
road).

Engine Dyno:
With an engine dynamometer the engine is attached directly to the dyno, the power
and torque produced are measured at the flywheel of the engine, hence the term
'flywheel power'. This type of dyno is mainly used by manufacturers and engine
builders for testing purposes.
If you want to see what it looks like, just ask, we've got one of these here at PECO as
well.

Chassis Dyno:
With a chassis dynamometer the power and torque produced by the engine can be
measured with the engine still in the vehicle. The main difference being that the
power is measured at the drive wheels and not the flywheel. Because of this the
results produced are always less than the results produced from an engine dyno. This
is due to the power lost through the transmission and tyres.
Most rolling roads these days will calculate flywheel power by measuring the drag on
the overrun, as will ours, however these figures are not, and can never be, truly
accurate.
Because of this I will not bother doing this test.
What really matters is how much power you get at the drive wheels, if you want to know your true flywheel
power then take the engine out and put it on an engine dyno.

How does a Rolling Road work?
There are two basic types of rolling road.

Steady State (Brake) Dyno :
The cars wheels drive a drum that has a brake, attached to it. The drum is rotated by
the cars wheels to a fixed speed. The brake is then applied to the drum until the engine
is no longer able to keep it spinning at the same speed. When this point is reached the
computer is able to calculate the power that the engine was producing.

This type of dyno is useful for calculating correct fuel and ignition settings at
particular engine speeds. Steady State testing however does not simulate the real
world. How often does a racing engine operate at a steady speed? Almost never, from
the start of a race to the finish the engine operates in an almost constant state of
acceleration or deceleration. The thermal dynamics of intake and exhaust flow,
combustion and mechanical components are much different under these conditions
than at a steady state.

Inertia Dyno :
The cars wheels accelerate a drum, which has a known mass. The computer records
how fast the mass is accelerated and calculates the torque generated using Newton's
law - Force = Mass x Acceleration.
The computer then calculates the power using the formula-
Horsepower = Torgue x RPM
5252
Simple isn't it?

Another advantage of an Inertia dyno is that it never needs to be calibrated, as the
mass of the drum cannot alter.
How do I make sense of the Graph?
The graph I will give you after your run will have two lines on it, one represents
Horsepower and the other Torque.

Horsepower:
This is measure of how much work your engine is capable of doing.
This is usually, but not always, the highest figure on the graph. Since it is a function
of torque and RPM it will generally rise steadily over the power run, ideally it should
be smooth and steady with no spikes or steps.

Torque:
This is a measure of turning force that the drive wheels are applying to the ground.
Torque is what makes your car accelerate. If you have a lot of torque your car will
feel fast. Torque is measured in Ib.ft. To visualise 100 Ib.ft. of torque, imagine a bar
1 ft. long attached to the centre of your wheel hub, then put a 1001b. weight on the end.
The weight would make the wheel turn. The more weight you applied the more torque
would be generated. Again it is desirable to have a smooth torque curve, an almost
flat curve would make the car easier to drive.
The torque and power curves will always cross at 5252 RPM. Remember the
Horsepower calculation? Horsepower = Torque x RPM
5252
so the BHP and Torque figures will always be the same at 5252 RPM.

PECO '8 Rolling Road
The rolling road that I will be testing your cars on is a DYNOJET 248x inertia dyno.
This is capable of accurately measuring up to 1800 BHP at speeds of up to 200MPH.
So no problem there then!

Most rolling roads have two small diameter rollers and the tyre sits between the
rollers. This encourages tyre deformation and wheel spin as most rollers that have
been used for any length of time have a polished shiny surface.

As you have probably noticed we have only one, massive, 4ft. diameter roller. The
tyre on your car will sit on top of the roller, that is almost a flat surface, as flat as most
roads anyway! The surface of the roller has been knurled so there is little or no chance
of any wheel spin.

What are you going to do to my car?
First of all there are a few basic checks:
Check your oil level, top up if necessary.
Check your water level, top up if necessary.
Check your tyre pressures, a few PSI up is ok, a few PSI down is not.
I'll have a quick look around the car, if the engine's making any strange noises I'll
probably recommend you don't carry on.
Next I'll position the car on the rollers and tie it down so it can't move. We don't
want to end up in the River Mersey do we!
If your car has a towing eye that screws into the front bumper, I would be grateful if
you could find it and screw it in before bringing the car in.

In order for the computer to do its job it needs to know how fast the engine is going.
This used to be a simple task of clipping a lead to one of the plug leads. However lots
of cars these days have direct ignition and therefore haven't got any plug leads. If this
is the case with your car then I will have to try and find a low-tension ignition lead to
connect to. Not always easy but I will try. If your cars' ignition system is hidden by
plastic covers it would save time if you could remove them before bringing the car in.

Next job is to position a large cooling fan in front of the car and a smaller exhaust
extraction fan at the rear.
Well we're almost ready to go. I'll need to know from you what the maximum RPM
you want me to take it to and then we're off
I'll drive the car through the gears up to 4th gear and then slow down to about 1500
RPM, floor the throttle and wait for maximum RPM, lift off the throttle and apply the
brake on the roller. Within a couple of seconds the computer gives us a graph showing
your cars brake horsepower and torque.

I hope these notes give you a better understanding of what it's all about and you have
an enjoyably and interesting day.

Dave Jones.

Just gettin ready carnt wait had a lot of problems with the car this week it must know its in for a beating cos 2day its a rolling road and next week (13th) its a airfield day unluck to the car. ( and if all goes t#*ts up my wallet)

On my way in a bit, just woke up

You were all lazy!

8:47am and 8:58am?!

I round the corner from the place trying to show Sporty the way at that time

Top day, review to be posted up soon
