RenaultSport clio 182 Cup
Hello all,
This is my first post on CS, so go easy on me!
I am the proud new owner of 54 plate inferno orange 182 cup 29K miles. The car is immaculate and I love it to pieces!!
I happend accross this thread while trying to find out a little more about the VVT system used on the RS range. I am a Mechanical Design Engineer and have always enjoyed playing with engines, hence my interest.
I am still confused as to what the RS VVT actually does? I have read this thread thoughly, and have no doubt that the long termers like Edde and Polarbert know what they are on about. What is your knowledge based on? First hand experience?
However this very morning I was reading an article in this months EVO mag about the new 197 RS. Included in the article is a short interview with some tech dude at RS. In the interview he says that one of the changes between the 182 motor and the 197 motor is the VVT system; the 197 system is a continuoulsy variable cam timing system, while the 182 system is a two stage system which advances inlet timing by 11degs at 5500 rpm.:S
I am new to RS ownership, so can't offer an opinion at present, but I thought I would throw the info into the arena! I'm sure I'm not the only one to have read the article?
Regards
Dan

182 VTEC???
Oh deary me.
You guys know that VTEC engines don't have a power boost above 5k rpm, but a power defecit below 5k rpm. VTec is s**t for low to mid range power because it doesn't have any.
Most petrol cars make more power the higher rpm they're at, if they don't there's something wrong.
BTW, if you want a real kick, try a Porsche engine
, power from the off, all the way insane power, then comes 7k and it kicks hard that extra last time before you shift, very special cars.

LMFAO, you should be an engineer. I'm sure Honda could use your expert help. They have obviously got it all wrong so far.

I admire the Honda engine for what it does / is... i.e. an engine with 100 bhp per litre and that can rev to 8000 rpm...
However, after having drove one the other day, I am left cold. I am not really sure it sounds as nice as I thought it would, not really better than the Clio for me, and the VTEC "kick" is certainly no more dramatic than the Clio 5k kick. I got to try it numerous times too, not just the once, so i know what its like by now.
The honda makes up for its torque deficit with low gearing + 6 gears.
I read somewhere the Clio's system is quite simple - it reaches 5k and theres like an on/off switch turned to the on position, quite abrupt... forgive my terminology i'm no engineer / mechanic, but its not a VVT engine like the Toyota Celica. Its far more simple & crude than that, but nevertheless, its also quite satisfying in its own way. Apparently the 197 is much more refined in that respect.

I disagree. Theres hardly any difference IMO between the Civic and Clio in performance. As for the integra, again, theres not a particularly big difference and the Clio is faster than some of the Integra R's...

What is "vastly superior" about it?
Nissan 350Z
Fair enough, but the outcome is pretty similar anyway. The 150 kg lighter weight goes a long way to help the clios cause....
FWIW i found the honda engine pretty soul-less despite its rev happy nature - and that goes for the rest of the car too... but each to their own

get turbocharged! love the sound of the turb spinning up! power comes alot earlyer!3500rpm 2nd! 0-60! 5sec!
certainly, in stock trim there are things that limit the capabilities of a road going vehicle. Most 2ltr engines are capable of an easy 250bhp, but you just wont see that.
But there is a reason why the K20 is used 200 times over for racing.
And to put things in perspective, the K20A cylinder head, at the moment with only a few years of flow development, is flowing NASCAR levels of CFM, renault is nowhere near....not even close.
Oh, and a stock K20A can be remapped to pickup absolutely stupid levels of power, in the order of circa 20-25bhp mid range, and swell over the 200bhp with minimal modifications in quite the fashion.
I love my renaults, but boy those honda engines are something else.
