ickle Ibiza on the Dyno again @ TSR

[ibizacupra]

Was on TSR's dyno today with CGTi on their 16v dyno day (+8v's and G60's)

Not been on their rollers for some time... mods to car since then. Goign to be an interesting comparison with Jame's (JBS) rollers which I am due to run on tomorrow with UKMKIV's.

ATW figure of 320bhp & 325bhp with massive wheelspin no matter how many fat blokes we could fit on the slam panel. Mr B driving it on the dyno cos of my sequential g'box. - TSR's (Neals) 2.7bi-turbo Passat with big turbo's, Motec etc recorded the same peak number, but sagged with heat on repeat runs slightly. - Both cars spinning up.

Watch this space for more dyno lottery after tomorrows run @ JBS

 

[Madmile]

Cool, i look forward to the Jbs results.

 

[Madmile]

Oh and good luck!!!!!!

 

[Madmile]

what boost u running now bill?.

 

[gillm]

yeh top morning . i had 102bhp @ the wheels . ha ha . nice to see the ibiza on the rr mate phat power

So the FMIC held up??

Good figures,

Ran again yesterday @ JBS...
Took a lot of fiddling with setting to prevent it lighting up the tyres when power pours in... Tried initial settings as wilko's IHI'd Golf had been using, but they span up as soon as boost came in on the ibiza..
Sequential box made for loud CRUNCH noises as James got to grips (kinda) with it

Coastdown losses made no sense as the g'box for some reason seemed to confuse the rollers software.. so atw mode was used.

3 runs when the settings were finally sussed to be consistent enough... (many more in reality to get this far)

328bhp twice and 330bhp @ wheels with 320lbft torque.

TSR's seems consistent within reason to JBS..

The A-M-Motorsport FMIC worked well. (still gong to get bigger core to recover some loss psi) but cooling seemed fine during the many JBS runs.. manifold remained only luke warm to touch.. Well done boys

Sounds nice
RoAr - Hissssssssssssssssssssssssssssssssssss

Thanks to James and UKMKIV's
Top day.. cheers Josh.. Burgers were nice too (yum)

sounded like a good day, hope to make it to the scn one

Sounded decidedly effin scary if you ask me. A bit like a jet fighter lining up for take of with a nice bang on the over run.

Cool. So any guestimate on the flywheel power?

As an aside, how does a rolling road know how many revs you are running?

I guess they have to take it upto a known rev level in the run gear and then press a button, and from that the RR knows what road speed equals what revs and so knows your ratio and so knows your revs through a run as a function of speed?

i think they just put a sensor on the coil pack wire that can read each spark,one spark equals one rev. then it does the maths.Or they can put a reflective tape on the 'crank' i think it is, and point a lazer @ it and it can count each time it goes round.

i might be completely rong mind

Depends on rollers... and software.
think James's did start speed (rollers) and stop rpm (test) and it calcs gear ratio.. then start run in gear to be used for test, set them to synch and go.

OR

Set start speed on rollers.., run car to that speed in test gear, press OK and then do the run.

Not off coil packs

Repeat run @ Raceshack on saturday.. FMIC testing under load

Was @ a new place in Tewksbury on saturday running ickle ibiza on their spangly new USA Mustang Dyno.. (huge thing)

Datalogging induction temps with FMIC, as a before measure, for Aquamist which I am fitting shortly.

Interesting results...
Dyno needs to know vehicle weight on their software so 1st step is on the compu-guages for phat ******* & ibiza to be weighed. Its heavy!

Roll onto 4 poster ramp, and up into the air, and onto the 5 foot diameter rollers. You sit on top of a single roller on this type, same contact(ish) as tyre on road. Strap ity down and run the motor up to find best gear for close to 1:1 ratio.. for me is 4th.

They programme in vehicle data, weight etc and the runs begin.
1st run is on my lowest boost setting... 8psi to settle car & me onto dyno. You run your own car on the dyno.

2nd run on high boost ~23psi and rips up the g'box and speed..

to the figures..
212bhp @ wheels on high boost with 189lbft torque....

Erm... not really.

Ran again, same results...

Now for the fun stuff...
simulated 0-100, 0-60, 1/4 & Vmax on the rollers... I only did 0-100 and 0-60 repeatedly..
Weird sensation trying to launch the car from standing on a static dyno.. Best 0-60 I managed was 5.33s.. 0-100 was hampered by 5th gear change again!!!! Arghhhhh fecking quaife!

Lots of logging and lots of induction heat. 60'C on full chat up the box runs (like it gets on track) - Aquamist and larger FMIC core needed.

Back to the power figures.. Had a long chat with them, as was going to arrange a SCN RR day with them... but with figures like these coming out what would be the point. Only relative to the other cars on the day. Silly low figures.
They insisted the USA software and Phd guys at Mustang were fixated on accuracy of engine power and the dyno was kok on. 212bhp, 189lbft torque from mine, did'nt equate to 0-60 times nor 0-100 times using their same arguement that the race cars who use their dyno (drag cars) log the same times as the dyno reads power. (they calc acceleration runs to derive power and the logged acceleration runs from the drag cars matches the atw dyno figure is their arguement) Hmmmm

I posed the question how a 212bhp car could outdrag a Porsche GT2 or Ferrari 360 in a straight line sprint.

Its a nice bit of kit, needs much better cooling fans, and reads low power figures, but is fun for the simulation acceleration runs.

Bizarre.
Will be back there in a while once Aquamist is on for setup and further logging.

[Shock_Xe]

erm, figures just a tad low, that torque is just about standard cupra R Ibiza power isnt it?? Deffinatly not right!

 

[BenS1]

How can so many RR's give such MASSIVE differences in results? And they all insist that theirs is the most accurate one available and everyon elses RR's are completely rubbish!

When you this ammount of variation in RR results it makes you wonder if there is any value in them at all (Except for comparative results).

Dyno needs to know vehicle weight on their software so 1st step is on the compu-guages for phat ******* & ibiza to be weighed. Its heavy!

You seem a bit cagey there Bill, how heavy is it?

Ben

 

[m0rk]

or maybe the better question is what did they weigh it with.....

not like their dyno was accurate, so why should the scales be.

I know kev's (with cage, but not a lot else) but brembo's & ARB's was about on the money full of fuel.

I'll post this up l8tr when I have looked at the paper note its written on.. and deduct phat b'stard me off it to get car.

2800lb's ish.. will post numbers and diabolical corner weight numbers later..
will add it was full tank of fuel, spare wheels, 2 x 5ltr oil cans, laptop so need to weight these and deduct them to get cars weight.
thinking as I type that lot.... thats a lot of weight alone.. maybe not so far off after all? Got to find out now.

This has to be the most inaccurate low figure ever... bizarre.
even by their own reasoning... a 212bhp car could accelerate in the times it did on the same dyno, and yet the dyno was dead accurate..

Stunning.. how far off the mark it is and them not see it for themselves.

off the top of my head thats 130kilos in "bits" roughly
