View Full Version : rolling road - oh dear!
as you may have seen in another thread, my cordy came up with a dubious power figure of 158bhp...at the flywheel :(
seeing as it came up with 170 odd befoore the chip at TSR, either the reading was wrong or i've got a bum chip.
all that money and effort for 8bhp...needs investigation

Chuffin bargain, ahem,
think the rr was a bit of a mistake cause everyone is disapointed bar maybe a few regarding their results. At least its experience, will help next time!!! my cordy aint even chipped yet, so id be well shittin myself if i was there!! hehe probably 60 bhp at flywheel or summat !!! heheh
scott ,got me wires croosed m8 thought yours was less than mine ,i think the whole thing can be put down as a non day,1st time ive been to one and now the operators are being blamed for not accomadating the intercoolers on the 20vt engine but what can be said of the n/a engines
neil was happy
martyn was happy
jason was well happy
scot ,it seems you may be right in the duff chip i would have thought that your cordy would be at least matching neils :confused: :confused: :confused:

Whats your spec Scotty?
What chip is it?
What registrations should I be looking for from Saturday to compare RR figures. There was one which had a very lean patch during the power run.
Give me some info and I'll have a closer look for you.

Well, although I was happy with my RR fig, im not too happy now. After I drove the car off the RR the idle felt lumpy as f*ck. The lumpy idle is still there and im getting slight dips in power through the gears.
I did have a very similar problem before xmas, it turned out to be a faulty lamda probe, which was replaced by Amethyst.
Same problem? F*ck knows :rolleyes:
Another trip 106 mile trip to Amethyst methinks!
thanks Bill,
my reg is P642 RNV, the spec is:
Gas flowed head,
fast road cams
Amd chip
supersprint cat back exhaust and rage backbox.
Neils reg is R730 CVV and he has a similar spec to mine.

What duration and make are your cams?
Makes a hell of a difference.

and another one for you.

We've updated the website too. Plenty of pics and vids to checkout including that mutant TT :D
We'll be adding more over the coming days. :)

hmm, thats the point - I was sure that they were reprofiled by schrick to 268 and 272, but apparently they don't do those durations? argghhh i'm confused - it does seem to be running lean, but shouldn't the chip control this?

Hi
Dont think Schrick reprofile cams - are you sure ?
They do 260's, 268's, 276's and then off into race spec 290 / 300's. You can buy each as exhaust or inlet and mix and match if you want - e.g 260 inlet, 276 exhaust. All are made from blanks I think.
The problem with 'chips' is that unless they are written specifically for your engine (and most engines even of similar spec are slightly different as evidenced by the variable results from std cars on the RR Sat) - like what AMD try to do - they will invariably be less than optimal. They will be way from optimal if you are unsure exactly what your engine spec is. The best , but expensive, way to go is am aftermarket programmable ECU (like DTA / lumenition / MBE / Emerald etc). If you go down this route however, you can loose all the features such as ABS, immobilizer etc (lots of post on this before).

RPm have done all the work on the car, and supplied their recommended combination of chip cams, etc - do you think the results look acceptable, or should I get them to have a look at it? (if they will?) Or do you think this is just a false reading due to my tracking being out?
Cheers.
sorry to butt in here (not RR related), Scott, send me an e-mail with your home adress please...ive got that cheque for you again mate. mike@seatcupra.net
I've just had a look at gerry 16v's standard engine dyno - 162.5bhp! There seems to be somethig amiss, his torque and at the wheels figure is way up on mine. I'm going to have to get it rolling roaded again I think.:mad:

Cheers. I can't comment on RPM's advise to you. They should know what they have supplied, and that the components match and should give a performance gain.
The only definative way is to do a before and after on the same dyno.
Cams and thei specs can make a big difference to the ignition and fuel settings, so the package can only really be optimised adjusting these on your car and blowing these parameters into a chip, if you have a factory ecu, or mapping them directly into a mappable ecu.
Did you get a before and after figure?
Did it feel better to you after the work was done?
Lots a variables I'm afraid.

Bill
I have the before and after figures for the chip (from tsr and PS - 145 at the wheels as opposed to 109bhp). It did feel better after the chip, but hard to say how much as it was running very lumpily and with a lot of lag - however its hard to say the difference over 150bhp as standard opposed to 160 or 170bhp, its all subjective. I think its faster, my mate doesn't, and now i've got some figures i'm not sure it is. My Parents have a standard Cordy SX 16v so i'm going to try and nab it tonight and see what its like against mine.
I'll also try and get a word with Paul, as he did the work and is a decent bloke so should be able to straighten it all out...hopefully!
