Cliosport power loss

[gaz44]

A lot of threads recently have been talking about power figures.

If, as stated by many people on here, Cliosports don’t make their stated power, does that mean they don’t make their stated 0 to 60. 100, whatever times? Rolling roads are apparently not accurate, so how is this being measured or is it just a CS myth?

It also got me thinking…when we read about 172 Cup v CTR and the there is “nothing between them”, does that mean that the CTR’s don’t make their power as both vehicles have approximately the same bhp/tonne on paper?

At the EA RR day nearly every Clio was underpowered, the same RR also RR'd a standard Mk3 1.2 turbo which run at 100bhp standard off the shelf and that made 101bhp, so that must be a good thing!

I do laugh at ppl with a filter and exhaust that say some RR gave them 180bhp from a 172, rofl. More likely around 170bhp.

you will struggle to find any car that makes it exact book figures. Of course there will be a few here and there but they are never that accurate. i have never seen a standard car make quoted BHP figures on a RR

I have but only one! A basicly brand new mk3 1.2 turbo at the EA RR day, was impressed.

... i have never seen a standard car make quoted BHP figures on a RR

My last car did infact it made over book as some of them do.

A standard 5 turbo should make 115-120bhp, when I RR'd mine with lightened and balanced flywheel, alloy IC and green panel filter, everything else standard made 117bhp, almost 15years old which I didn't think was too bad.

At the EA RR day mine made 171 with different airbox, compare that to quite a few that had exhuast, decat, filters and RS Tuners that still couldn't break 180, highest was 177 I think. It all depends on how they were run in and how well they are looked after/serviced etc. It's not as simple as every car making book figure. Civics will have the same problem

Yeah - sorry to clarify, i meant some over some under, not all under.

My Clio made it's power on the nose but at a different RPM than quoted by Renault. Torque let down but the exhaust as it leaks a little at lower loads/rpm.

Roller seemed to be producing accurate enough results. A couple of JDM Integra Type R's were coming in below book at 195bhp. VR6 Golf's, Subaru's and diesel Fabia VRS' all made book figures where standard and slightly more where modified.

The chaps at Wallace Performance said they'd had a few Clio's that made below book and were aware it's an issue.

 

[Tobs]

was your car standard?

 

[gaz44]

So is it inconsistent manufacturing that causes the power loss and is there always an expected power loss percentage expected on every car built?

Seems it's common knowledge that Cliosports tend not to make their quoted power.

 

[Tav]

was your car standard?

Yup, had 26k on the clocks. Standard everything, recently serviced. It might have been remapped as it revs quite high but I'm not sure the if that would have been something the previous owner would have done. He was a BTCC champ so that's prob. given it a few extra BHP haha

 

[TooneySonic]

they are all different, a strong 182 should see just above 170 on an accurate set of rollers, a 172 around 165

 

[Inferno]

There's only one way to know the true power and torque that an engine makes, and that is an engine dyno. Rolling roads are only good for comparisons with other cars on the day in question.

I have never heard of a standard Renault 1*2 lump being put on an engine dyno - it's simply too much work.

As for the 0-60 times, Renault were quite reserved with the figures. I believe they quote something like 7.1 and Evo magazine independantly tested a 182 cup that achieved 6.5.

I'd say that even with the variations of production, all 1*2's should be able to achieve a 7.1 second 0-60mph time provided it is maintained correctly.

yes that was very random lol

meh my 182 only made 161bhp but the torque was mad!

 

[Martyn_182]

tav how much did wallace charge for your rr? wouldnt mind finding out how much power my 182 has

 

[Tav]

I went with EastsideVW as part of a rolling road day so it was £30 I think as there were about 20 of us. They have a website so have a gander on there, should have prices. Would be nice to compare results of two 182's on the same rollers.

 

[Martyn_182]

might have a trip up soon. my cars just standard apart from someone has put some airfilter on it. think its a pipercross viper. the v6 airboxes any good?

i dont know if people have figured anything out but if you stick your hand out the window doing 100 mph and sticking it in front of them fans on the rolling road there is a alot of difference, the fans cannot replicate that kind of airflow, the only place would be in a wind tunnel that formula 1 teams use, especially turbo cars.
why do people worry about how much bhp there chucking out of there cars, when they usually have only a few mods.
why do the clios keep up with other cars in all the threads that people put up,maybe renaults dont work to well with rolling roads.
what do you lot think of that maybe i am wrong.
something to think about

Eh...not sure what you are asking here?

Do you mean the fans don't replicate wind speed at 100mph and therefore don't allow enough air into the engine?
