LOL @ u lot

Get yer han bags away
An OI!! T-UK NO!! U gotta *** up wiv a better 1 than that 2 egg me on m8ty (2 much management trainin 2 rise 2 that ol chestnut )

BTW yeah big red will b @ crail n hopefully runnin a lot better
than she was on the rollers.
Sam, i`ll fit an airbag on u r side so we can get her mapped right up an c wot this TD05 will really do (are parachutes any good 4 braking)??
Was talkin 2 Dave an it sounds like 1 of my gaskets has gone, wot a barsteward. All goin 2 plan though may ave the new twin zorst system on so no power loss there, gaskets replaced / upgraded,
all silicon under bonnet, an a few odds n ends

Yeah it`ll b interesting 2 c Daves n my motas on strip.

So see u guys there if u wanna kick some wrx butt LOL
BTW still hold the top scoob terminal speed @ Crail 105mph
jus so u know what u r up against (that was b4 the last
round of "upgrades")

L8r if u got the pods
Pete

Late shift this week, don't sleep till 2am

New track at Crail this year, nice n smooth

Sam,

U r on the money m8 it is indeed insomniacs night (same as every other night 4 me, only sleep max 4 -5 hours)
Crail, hell yeah lets give that monsta of u r s summin 2 remember

Andy,
Flat surfaces r only any good if u actually come in2 contact with them That mondo rear wing on mine aint 4 show m8

Running 2 PSI more boost and a tightened actuator compared with last time and also getting them to turn the load on at the correct time - my car showed peak boost at 3100rpm but peaks at 2400rpm on the road - I think that would affect my torque figure somewhat. Oh S**T I've given away all my secrets! Not that they were that good or secret anyway.

Depends on which figure makes the "king" I suppose

Yes, your car did have good torque...

Took my Scooby down to Star Performance in Glenrothes today to get a power run to see what my latest mods have achieved.After a couple of power runs, Jim took the time to demonstrate some of the other features of his Rolling Road.
Firstly he checked the calibration of my speedo by running the car up from 20 - 100 mph, and storing the results for every 10mph increment.Then he printed out the graph which shows the actual & measured speeds.It showed my speedo reads 3 mph faster than I'm actually going.....handy to know.
Then the fun started....
To get a measurement of how my performance upgrades have improved the car in relation to book figures, he did 2 runs from 50 - 70 mph.The first was in 4th gear, which was a time of 6.2 seconds..sounds slow, but remember UK gear ratios so it was only just coming on boost @ 70.Second run was done in 3rd gear, which was a more impressive 3.2 seconds (plenty boost & revs ).
Then the best bit (Jim was smiling ear to ear at this point) he did a 0-60 run in 5.8 seconds.Suprisingly there was no signs of wheelspin, and it was well impressive to watch.The car squatted right down at the rear & looked poised to jump clean off the rollers He commented on using a better strapping down method for next time I think if he'd had a few more tries at it to perfect a quick 1st to 2nd gearchange then a sub 5 second time may have been achieved
It was quite a sight to see & hear your car sprint from 0-60...and not go anywhere

So to get a bit more information on your cars performance, why not give Jim at Star Performance a ring & book an appointment.He wont offer this service at our sunday RR meets as theres too much setting up time involved, but happy to do this by appointment.

And if you're interested..My scoob got-

287BHP - max power at 108mph/6040rpm
200.5 BHP @ Wheels (over 200 at last)
67.5 BHP drag
280 lb-ft torque at 3800 (holds flat line up to 5500)
1.3 bar held from 3500-6000+ (at shut off point)
*solenoid disconnected-using superchips bleed valve only*
and 10.4% CO on boost

now all I need is that fmic......

Hi Dave, I take it you would recommend star then. Do you have their number as I have been trying to find it so that I can get my car setup at last.
I will see you on friday when I am in at awd getting my blitz filter fitted.

cheers
sandy

Dave Brown

Hi Sandy

There number is 01592 770377 or www.starperformance.co.uk

See you on Friday m8

Do you know why, when doing a power run at Star, the time spent on full throttle from 2000 rpm to 6000 rpm is more than double what it would be on the road ?

It would appear that from what you say Star have the capability to let the car run up to speed as it would in 4th gear simulating road conditions.

I would have thought this was what was required for a power print ?

From prints I have seen from PE rollers the car runs up to speed at around 300rpm/second. I timed it at Star the last time and it was almost double that ? Is this something that Jim can adjust/control ?

Good results btw, shows that less boost can = more BHP !!

ps New target for John Banks to aim for !!

Dave Brown

Cosie

Jim would be the man to ask how it all works, I can just assume that the rollers generate their own rolling resistance in order to work out the torque & bhp figures in a power run.
When he did the 0-60, 50-70 tests, he first input the weight of the vehicle, then the desired speed parameters before running.I would guess then the software uses these figures to load the rollers to best simulate road conditions.

He can preset any speed you want eg. 0-100 mph time

BTW his RR was checked & re-calibrated yesterday, engineer said it was spot on & made no adjustments.

I aint no RR specialist, so feel free to correct my babbling.

Dave

Dave/ Cosie,

Most RR's are adjustable for accel. speeds and mass resistance on the rollers, so that the torque curve can be obtained without overshooting the rollers. Imagine one of those Vauxhalls running up in 4th to achieve a reading and putting Keiths monster on next and doing the same, it would spin up in no time and launch out the window. I'm not sure how Jim sets it up, but it'll not be far from the above.

Dave, interesting reading mate. Me-thinks I'll have a go soon

Cosie Convert

Note to self, Speak to Jim and learn about rolling roads

I know I keep harping on about it but I firmly believe that on a turbo car (especially a TMIC one) the lack of intercooling on a rolling road will rob it of power. Extending the duration of the run will cause more heat build up and even greater losses

Perhaps this has something to do with the reason PE rollers seem to give a higher reading than Stars ? I presume they are both calibrated to the same industry standard.
Does anyone know if there is such a thing as a "standard" rate for RPM climb on Rolling Roads ?

I'll try posting a similar question in PE's local section.

Sam Elassar

nice one dave

good results what i want to know is how did you achieve that much BHP? the turbo will not flow that much. the compressor map of the standard TD04L turbo kind indicates around 275 at 1.3 bar at really high efficiency which you would get for example if you have a FMIC fitted. so spill the beans what have you done

sam

T-uk

good results Dave,come on tell us how you got over 200@ the wheels.are you still running the standard ECU,I guess that your car has the black AE800 ECU,really must get one of those .

if your still running a top mount and standard turbo,john banks will be struggling to keep his top spot unless he pulls something out the bag

the way I understand rolling roads is that you can "stab" test a car(foot to the floor) or build up gently,the later is supposed to be more accurate.

john banks

1.3 bar at 6000 RPM is surely the key. You are leaving me behind big style m8. Now tell me what turbo you have on!? If you say TD04L I will eat something inappropriate and buy you a pint and gently ask about temperatures....

B**ger I thought I would be chasing your figures next time.

Compressor wheel required me thinks

[Edited by john banks - 1/31/2002 11:05:33 AM]

john banks

3500RPM for peak boost is suspiciously high for a TD04L me thinks As well as a supsiciously slow time for 50-70 in higher gears.... Put me out my misery and let the dog see the rabbit m8...

[Edited by john banks - 1/31/2002 11:33:18 AM]

john banks

You've got me all intrigued.....

Damn!!

Fantastic results m8.

Now tell me what you ******* did!

Cosie Convert

I've seen it go at Crail, it fair shifts Made a Std UK look like it had taken away in 3rd !

john banks

That was the 1.7 bar version though. I think he has sneaked a VF23 in there when no one was looking

Cosie Convert

John

I think I'll get you to help me with the excuses when Sam thrashes me at Knockhill

john banks

Get rid of that "intercooler" you have and you would go a bit better? What about that one you were on about? I was hoping you would try it first.

A nice upgrade path for me might be TD04 beefy compressor wheel and this intercooler?

Sam Elassar

no john don't do it.

john banks

I will wait to see with interest what Dave has done, and see how I go on track first.

T-uk

laughing gas,may-be? ,I'm sure Dave's still smiling

john banks

Hadn't thought of that....

I could always carry it "for medicinal purposes"

Sam Elassar

usually this is what i am on

Cosie Convert

NOS ? mmmmm now I used to have a kit in the back of the garage somewhere.................

john banks

See what you are dealing with Sam - this bloke actually is a complete nutter

Cosie Convert

I had NOS on my last kit car. Two stage, Stg 1 +70 bhp Stg +150 bhp. But that was a 6.0 V8 Chevy engined kit car.
Wouldn't give a Scoob the same dose ! But as Sam suggests, 70 may be enough

Sam Elassar

ooops

john banks

I have visions of Dave Brown and Cosie Convert teaming up and making a 30PSI 2.5 litre turbo nitrous monster.
