Lack of a 5k kick. Normal?

[-Leigh-]

Test drove a 172 at the weekend, and I'm alreday to put a deposit down on it, apart from one thing that's bugging me.

When I took it out, after warming it up, I put my foot down in 2nd, but there wasn't the normal 5k kick, and it didn't seem that quick. I told the salesman (actually a good helpful chap) and he said no worries, go back to garage, drop him and the g/f off and take it out on my own and give it a go then. I did this, and it seemed quick (115 came up quite quick uphill) but still not that kick as both my 172 and 182 had.

I've read on here not all seem to have it. Only thing that bugs me is, when they got it in, they did the cambelt. Could it be timed up wrong? The plugs on the end of the cams have obviously been removed/replaced but is there anyway to tell?

Or could it just be that this one doesn't have it as much?

Ideas?

I always thought that if it was timed up wrong it would be lumpy/misfire.

Any chance that it's been remapped so that the kick is less noticeable?

 

[richy22]

I have 2 kicks in mine Yesterday on Track it would kick at about 5K then again about 6K..I was like WTF?!

 

[Fletcher]

Since having my maxogen fitted i don't really get a 5k kick, it pulls smoother through the rev range.

Well when I bought my 172 years back, the garage did the belt and it was timed wrong, and you could tell, it was lumpy to drive. This one is smooth, and went quite well when I was on my own.

I don't think it's been remapped, maybe checking to see where the limiter was would have confirmed, I never went over 6800 as not much point.

It had standard filter, and exhaust so don't know. Maybe it's just not as noticable in some?

Only other thing that bugs me is it has 4 good tyres, but made by "accelera" or someone, meaning I'll have to shove 4 decent tyres on it.

 

[Christopher]

It also depends on how the car has been previously driven. The ECU learns and adjusts various parameters to suit. Maybe the car's ECU is just not "used" to being fully extended.

A clip flash would solve this, if so.

 

[JR]

Aftermarket exhaust ?

Increas in I/D or Bore size will get rid of the kick, the kick is actually the end of a flat spot.

So if it does not have it there is a chance it will be smoother through the rev range and have a more linear curve if it were put on a RR'D

 

[Christopher]

He said OE exhaust, bear. Mine still kicks with the Milltek on, too. That's 63.5.

 

[JR]

Cant read = Fail.

 

[-Leigh-]

Exhaust looks standard, although it could be a pattern part, being 5 years old I imagine it would have had a new one, standards are crap.

It may be fine, just wanted to check. Felt ok to drive.

 

[JR]

Mine does not really kick that much any more, but that's due to the Group N map.

 

[Christopher]

I'm betting an ECU flash would have it kicking again, in no time.

 

[-Leigh-]

RS Tuner sort this out?

 

[Christopher]

Yep. You can set it to a default map with the RS Tuner unit.

 

[-Leigh-]

May have to put a deposit on it then.

 

[Chris n nic]

My Cup doesn't have as pronounced a kick but obviously this is because of the mods. Nics std 182 feels quicker because of the big vtec yo style kick where as the Cup pulls hard from low down and then gets a boost a couple of times before the limiter

Mines does.. lol, the joys of VVT

 

[McBunny]

Mines does.. lol, the joys of VVT

but its not vvt lol

 

[Shaunyboy]

but its not vvt lol

?? the one 172 & 182 use VVT, same as the civic type r's. Hence why both are normal to a certian rpm, then the vavle timing changes giving it that kick

Honda's use vtech y0.

Clio's do have vvt, but it comes in at about 1250rpm and has nothing to do with the 5k kick.

 

[f0xy]

vvt is at 1200-1300rpm on 1*2s, its for low down drivability. lol.

edit. beat to it doh.

 

[Jonny1*2]

is it a ph-quick? the rev range is different if so. Power is smoother and less of a kick at 5k over the 182. If it has an aftermarket induction kit on, it might be restricting the engine. Mine changed a bit when I removed the standard box.

No it's a ph2 172.

Ok i stand defeated, so explain what this mysterious kick is then

It's just when the engine is at it's most efficient.

Thought it was 5k that the larger cam engages and hense vvt?

 

[f0xy]

there is no 'larger' cam...its nothing like vtec.

vvt = variable valve timing, it changes the position of the inlet pulley at a certain rpm (1200-1300) to aid low rpm driving.

the 5k kick is purely the design/components of the engine, hence why it sometimes disappears with a map/and or different inlets/exhausts/cams etc.

ie. when I had standard cams with the rstuner grp n map, the 5k kick was gone (map smoothed it out). after fitting my schrick cams, i get a huge surge of power at 4500, because thats the way the cams are designed...

get in ya box :rasp:
the 5k Kick is just it coming on cam (and map flatspot) nowt vtec kicked in y0 about it

+ i hate it been called the 5k kick it makes it sound like its something special when it isnt oh that and the shift light being the optimal place to change gear MY ARSE !!!

Should I have called the thread "Lack of that little surge of power when the revs get to 5,000 revs that happens in the Clio 1*2's, y0?" ?? :rasp:

 

[f0xy]

As mentioned earlier also, it *could* be the timing...Dont know if you remember Burps 172 ph1, used to run fine, just felt a bit underpowered....

He had it rolling roaded at 140odd, then checked the timing and it was out. It can be a certain slight amount out before it starts getting lumpy/getting valve contact etc...Its not a quick job to check though as you probably know...

 

[McBunny]

i dont remember mine having a 5k kick either 4k rattle yes

the exhaust was 70mm though

No need to take that attitued, i wansnt saying about vtec yo, i was stating that i thought the clio used VVT similar to hondas VTEC system, as said i stand corrected

Vtec is an entirely different set of cams, not VVT

 

[McBunny]

sorry it just really really gets on my tits when people go on about it being the same as vtec or i-vtec or even i-vtec i

 

[Christopher]

VTEC is nothing like poverty VVT. LOL

VVT on Clios is purely for low-speed drivability and emmisions regs., as people have said.

VTEC engines use separate cam profiles and lifters, and hydraulic/electronic control to manage the crossover. Renault's VVT is never "off"

And what do you know of V-tec? x

 

[Christopher]

Edited. x

pmsl - nice work.

We never stop learning matey

Vtec is an entirely different set of cams, not VVT

there are a few different vtec systems, but the basics is thus:

Its not a different set of cams, instead of having one cam lobe for each valve, Vtec uses 3, smaller one used at lower revs, the other remaining still, when vtec is reached, oil pressure shoots a pin through all the lobes, bringing the other larger lobes into play, meaning valves stay open longer=more power

sorry it just really really gets on my tits when people go on about it being the same as vtec or i-vtec or even i-vtec i

Sooooooo agree with you there mate lol

vvt emmisions regs just kicked in y0

Tbh its just witchcraft and there is no impressive mechanics going on. Pure hocus pocus y0
