more power at 5000rpm

[mickrach165]

hi there, iv only had my 182 for about a month and iv noticed when im giving it some it pulls like hell but as soon as it gets to 5000rpm the engine note changes and it pulls twice as fast. wots all that about then? is it normal or wot?, the only other car iv been in that does that is a civic type R. can anyone help me at all?.

 

[cK]

yes it's normal

 

[Davey182]

is he ^^ havin' a laugh?

 

[G_F]

Its to do with the flux capacitor Mick, have a search on google for it.

 

[tommyboy]

It's normal

 

[philmots]

Why take the piss?

I'm sure it aint technically correct but they just kind of come 'on cam' at 5k hence pullin like stink.

 

[oska]

Didn't you know? There are families of hamsters that live in all RS engines. When you hit around 5000RPM an electric charge is sent into the probes they have up their arses. This sends them into a sexual frenzy and they run round their wheels twice as fast, thus the extra power!

Another handful of helpful posts by members i see!!

my corsa SXI used to do this at 4500RPM pretty sure most modern cars do.

 

[adrian182]

yeah its normal its the clio power. DrRollo never own up to having a corsa ur rep will sink real fast

sweet jesus I hope your joking

 

[DrR]

wasn't a bad car for an 18 year old! 2002 SXI, better than a clio seemed to get way more power at that rpm.

 

[Martin]

Yeah 16v engines will do that.....even 'modern' 8v's won't get anything extra at 5k....

 

[davejm123]

yes its normal. nothing to do with hamsters lol. goes on cam, and becomes more efficient hence more powerful.

 

[FlameR]

Feels like mine has lost a bit of the 5k kick Do you reckon if I fit a cold air feed to my CDA and route it to the bottom grill it will make much diff? Cos I've left the CDA open at the mo. Sounds mint though

true, but i find sometimes, if not allways itll pull ok till 5k and a bit, and then it slows all the way to 6k.

Now ive got my induction chav kit its allrite, there s alot more power at the top end and it pulls really well up in the revs.



......when i say really well......its still piss poor.

yeah ok :quiet:

No mechanic but I heard it was to do with the second cam powering up. If you change the cams for ones with a better profile you can get the power to come on earlier or get them to rev longer.

CDA?

 

[172_girl]

^^^ think he mines bmc, which shouldnt be left open as its a ment to be a closed induction kit

 

[Lagerlout]

I have to ask who's more foolish. The fool or the fools that mock him?

It's the cams reaching their most efficient point at a certain rpm range. In the case of the F4R the cams pull much harder after 5000rpm.

Try here dude. Explains pretty well how cams work and what they do and there's a great animation near the bottom of the page that shows the difference between 'normal' cams and 'performance' cams.

lol i was just searching that article!! b**ch

 

[Peperami]

By closed it means that the box is closed off from engine heat, dont need to connect the feed to them.

If you disconnect the pipe, and have it pointing at the front of the cda, it'll be a lot louder, and some reckon it runs better.

If you look to the right of this csl bay, the airfeed is open, with CAF coming up from where foglight would be on a standrad m3.

Sounds like your engine is producing more low down torque which helps mask the kick at 5200rpm.

 

[davejm123]

http://auto.howstuffworks.com/question229.htm maybe that one might help too? if your really interested! it seems to be a thing that IK's take a bit of the kick away but dont know how true it is! you wish laingo

 

[FlameR]

Yeah sorry BMC CDA. I would have used the provided cold air feed but its way too big for under a clio bonnet. And it'snot flexible

 

[Peperami]

Should be able to fit any feed mate, zip tie it in place in the bay pointing towards front of the kit. Pipercross sell slimmer ones, as do demon-tweeks.

 

[FlameR]

Yeah I need to get a flexi feed one I think, that I can route to the bottom grill!

Its actually the dephaser solenoid advancing the timing via the dephaser pulley on the inlet camshaft.

Newer 1.6 16v engines and also import scenic rx4's have this pulley fitted to, but i think its just the rs's that you notice the kick on

f**king hilarious , can we have a comedy forum for Gavfre to post in?

Its to do with the cam timing advancing not sure on the technicalities but I would be interested to know myself.

Cool, ask a mod to setup a poll

I thought that the dephaser stuff was for the VVT, which on the RS is used for emissions purposes and kicks in circa 2k rpm?

I was always told it's just that the engines are "on cam", my old 19 was the same.

 

[Martin_172]

its nothing to do with advancing time or VVT.

5k is the point when the cam timing starts working at its best. i know my mums 1.2 16v has a slight kick at 3k, but mine doesnt, (dont know if the newer 1.2 16v engines are twin cam compaired to the single cam ones before 2004?) only reason the F4R has a much bigger kick is due to them using more wild cam timing.

hah clio 1.2 is fast if u look at stats plus when u think of corsa u think my good i feel sorry for u driving that lol

 

[Peperami]

2002 corsa's are nice cars, despite the stigma attatched to them. Better build quality than clio's too.
