Robbie C's Ibiza Cupra

[PhilW]

Ive said it before, ill say it again. JBS = FULL OF ****


On a side note, you think this could have affected the power run you done at Bills vs. Craigs?

 

[Robbie C]

This is just awesome mate

On a plus note, the car looks really smart mate

Thanks

 

[Cupra-Martin]

I´m happy that i not have ordered my manifold yet when i read this...

It's an interesting point about the RR, but impossible to speculate anymore than what's already been covered as I see it with regards to the difference in RPM scaling.

The logged airflow seems to tie in with the figures - I still think ambients are a big factor which is why I'm interested in getting a comparative run in winter to see what margin of difference it makes. That should give a more definitive answer.

I'm going to replace these bolts with a set of Nordloc washers to try and keep them in place, then I just need to get the car ready for Combe next month with a fresh oil change and a new pair of track shoes

 

[PhilW]

Jog my memory, did you log airflow when at Craigs?

Whats at Coombe next month? Rally Day? Tempted to go down this saturday?

 

[Robbie C]

Unfortunately not, just blocks 118 and 020.

When Bill was logging the car in December during remapping he saw peak g/s of 227, and 215 on the power runs with much higher ambient temps. There's no way of knowing for sure at what point these bolts became loose though.

There's a Javelin track day at Combe on 4th October, open pit

Yeah I'll be at the rally day on Saturday but not in my car now... you going along mate?

 

[PhilW]

So with the same gear, same ambients, logged air flow and a manifold in place the result could even out.

Im thinking about going to the action day this saturday and the rally day yeah, ill let you know.


Hope it all gets sorted ans JBS pull their grubby little fingers out and at least go some way in mending that awful reputation they are gettin.

 

[Robbie C]

I would say it's difficult to fully account for exactly how the RPM scaling skews overall figures (other than the obvious transition as shown on the plots, which outlines to difference in RPM ratio between what we believe to be 4th and 5th), though Craig commented that peak flywheel power should remain fairly consistent.

Without boost or air flow figures from my initial run to compare against then it's impossible to take too much away from this as acknowledged by Bill, but another run in Winter with everything believed to be running 100% should be interesting just for comparison though I'm not getting too hung up on numbers

Nice one, would love to see yours in the flesh again now - not to mention a thrill ride to appreciate just how it feels!

Don't do it Robbie, you know once you go out in Phils that you will want more.....as we discussed at E38

 

[Robbie C]

hahaha, yeah a potentially very dangerous game, though intrigue is getting the better of me!

I went out in a colleagues Tuscan at lunch, but it actually had the reverse effect I imagined. Admitedly a very nice quick car with an abundance of torque (and my god what a noise) but when I think of the money he must have paid for it vs the relative performance of mine then it made me happy with what I have.

By his own token, after coming out in my car a few weeks ago he commented that the Cupra "felt" almost as quick - but they are two very different cars with different deliveries of power. Not forgetting a valid point that my car (along with many others on here) was never intended to deliver so much power from the factory so the feeling is perhaps heightened when sat in it, for an outsider who doesn't expect it from a little hatch. Don't get me wrong, obviously I'm not disillusioned to believe it is as quick as the Tuscan, but I don't necessarily believe it would be out of his rear view mirror either.

I think my point is to replace the Cupra with something equally as quick with more desirability/status on the road would require a very large cheque book so I'm content with what I have

Great point Robbie, you can't beat the feeling of someone coming up to you at the lights in there relatively large/ powerful car and getting a slap in the face when a small hatchback stonks past them lol in a Tuscan people expect it

wow mate looks soooo nice wish it was mine

 

[Robbie C]

Hope it all gets sorted ans JBS pull their grubby little fingers out and at least go some way in mending that awful reputation they are gettin.

I've followed up with more emails but no such luck Phil.

Thankfully Bill has been more forthcoming to help (anyone noticing a pattern here?)

Change the title of your topic to "JBS are full of ****" and when google starts showing that in search results they'll soo change their tune.

 

[turbo009]

Quite a few people are moaning about JBS lately I here. Read this on another vag forum somewhere

 

[ibizacupra]

i dont think they were loose when on the rollers, we would have heard it i'm sure

 

[Robbie C]

Agreed. On the way up to Edition I did hear an occasional noise that indicated something wasn't quite right, and the car has covered ~400 miles since being on the dyno.

there is a difference in the original dyno run from the report run, as it reported 5th gear as test gear, but also reported the final drive ratio, which was for 4th. Given there were traction issues, and the over wishbone strapping points were'nt there back in feb, the climbing up the front roller would likely have been occuring. Craig added more strapping points for my visit with my ibiza in May, so I dont think the over wishbone method could have been employed in feb by this token. It works, and was good advise by craig to employ this method, as we used it on robbies car on sunday and on dales corsa turbo, and wheelspin was'nt an issue once warmed up. choosing 5th would have helped tame the power delivery, but its a different load, and if the rpm scaler was different from the 4th/5th change then this would skew the rpm/torque readings.
I know when I change the ramp rate for a slower ramp rate, the plots all shift to the left, not to the extent of the difference between Febs plot and sundays tho.

hope this explains
bill

Hi guys, just want to try again to shed some light on this...

Bill - Bare in mind that if you calibrate the dyno for say 4th gear, perform a run and save it, then re-open another run overlaying the 1st run but re-teach 3000rpm for a different gear, it will only report the most recent change on the customer printout for calcualted MPH/1000rpm for run1 and run2, but the 'gear used' simply displays the gear you have told it you are using when last taught. You can tell it your using gear 1, as long as you teach it in your run gear the results will be correct.
Next time your on the dyno teach a car in 4th and perform run 1, then immediatly perform run 2 in 5th gear, you will see how vastly different the dyno will report RPM as it is derived from roller speed and my reasoning for saying that the dyno wasnt calibrated for one gear and ran in another. Please report back results to confirm, this is off the top of my head, i havent tried this so im interested in the result.

The reason i only took Robbies car to ~ 6500rpm was the steep drop off in power at that point, i dont search for rev limiters if the power has already dropped off.

You know whats going to really confuse people, come for a run on my Mainline and try and compare all 3 runs ........ LOL

 

[ibizacupra]

I will try this on next car IU have on there.. will report what happens.
the single loaded report from feb, on the print out, showed the feb results tho, as I did not run the car in 5th at all on the day robbies was with me, it loaded that data from the feb saved runs.

its very repeatable.
playing with ramp rates shifter the torque to the left of the plot (more load obviously) but did'nt increase the level of it.

I cant account for why the dyno now reports less torque that it used to when yours, but std cars still remain bob on when run. good ole lottery..

 

[Robbie C]

Thanks for the continued input Craig/Bill, it's good to hear your thoughts on this.
