182 5k engine kick?

Rob182 · Mar 25, 2006

why does the 182 have a kick at 5k revs? i know its not w turbo so why is there a kick at 5k?

And can you change it so it kicks in at 4k?

Thanks
Rob

variable valve timing in english lol
not possible to lower it mate,not for sensible money

gazcaddy · Mar 25, 2006

Yeah VVT (Variable valve Timing),

I love the 5k kick!

Rob182 · Mar 25, 2006

did not know if it could be changed on the computer LOL

Guy · Mar 25, 2006

aparantly its not the VVT..

think its when it comes 'on cam'

VTS/106 gtis have a 4.5k kick.. theyre not VVT.

VVT vary with make the of car, could be called something else?

It's all the same VTS/106's have two cams and only when its reved does the second cam come in.

mr bognor · Mar 25, 2006

Yeah its called ON CAM nothing to do with the vvt .

Fred@BTM · Mar 25, 2006

VVT comes on at 1600rpm (ish)

the 5K "kick" has nothing to do with the VVT

mini ripper · Mar 25, 2006

The 2ltr Reno engines have variable valve timeing (It says in the manuel) otherwise known as vvt Toyota call it this and Honda call it vtech.
I do rather enjoy the kick. I know with the CTR's you can have a box so you can adjust it live. Thier was a listing on ebay that said you could control it but looked to simple to be true!

What is the kick all about then

Martin · Mar 25, 2006

coming on cam ffs it's a 16v engine

Fred@BTM · Mar 25, 2006

its the point at which the cams become most efficient, "harmonics" and all that fancy stuff BenR bangs on about

its just the design of the cam

with the schricks we use it has the "kick" at around 3500rpm, again, just the design of the cams

Well I dont know hence why I asked. I am a Dairy Engineer and know feck all about motors other than what I need to know like wherte the dip stick is!

Cheers I feel informed yozza

blink172 · Mar 25, 2006

Ive got one of those adjusters, they're pukka. With the 20bhp increased chip and electric turbo all from the same oNline sTore, i reckon there is little out there to touch mine.

Not VVT as said.

Thats Fred.

Fred@BTM · Mar 25, 2006

i've no doubt made a mistake, and BenR will correct me

rory182 · Mar 25, 2006

its the sweet spot of the cam basically, change the cam for a lower kick, as Fred says it'll vary according to the cam profile.

I stand corrected, although I must point out when I asked the renault salesman about the 5k kick he informed me that it was because of VVT!!

They really dont know much about the cars!

Fred@BTM · Mar 25, 2006

well remember Renault salesman think the earth is square

W3STY · Mar 25, 2006

So would some kind person please provide details of this 5K kick. I always thought is was the VVT but obviously not now.

Please bring Ben R onto the stage for his recount of this so called VVT. (Va Va Voom)

Oh and Fred, if the shrick cams you are on about "Come In" at 3500rpm. DO you get the same kick and does it pull as hard at that RPm as the normal 172/182. (god i'm a numpty)

This explains it some.

Thomss · Mar 25, 2006

Good site Rory.

ChrisR · Mar 26, 2006

Also VVT and VTEC are different types of system iirc.

VTEC has pairs of cam lobes and at the set point it shifts from one to another, doesn't vvt use just a single lobe but alters the angle of something somewhere? (technical talk there!)

E-ray_172 · Mar 26, 2006

it also sounds very nice after 5k

lets not forget

Rich · Mar 26, 2006

The vvt on the clio is really just there for emission purposes and is different compared to the honda VTEC system, which effects both camshafts, on the clio it is only on the intake cam.

http://www.ukcar.com/features/tech/Engine/vv/vvt_3.htm

the 5K kick is the car coming on cam.

Andyvalver · Mar 26, 2006

So basically its just cam setup? The cams are set up to be most efficient at 5k and thats when you notice it pull harder. Valvers/willys are the same.

ChrisR · Mar 26, 2006

Yeah, my old 19 valver was similar, had to wait until 4.5k until it woke up.

Least with the Clio there is some grunt before it comes on cam, just you don't really notice it. Drove my folks MX5 the other night and that felt absolutely pathetic in comparison, veyr revvy but below 4-5k it felt as bad as my other halfs micra

But then that was just the perception of the speed as it's a little quicker than that

fmp_ · Mar 26, 2006

just going back to the first page....

'It's all the same VTS/106's have two cams and only when its reved does the second cam come in.'

are you aware of how wrong that statement is? Like the 182 engine, it does have 2 cams, but one is inlet, one is exhaust. They both run at the same time, at the same speed. One doesnt start spinning at a certain rpm.

As for the clio 5k 'kick', its a hell of a kick for the car to be coming on cam!

Mike_SE · Mar 26, 2006

"As for the clio 5k 'kick', its a hell of a kick for the car to be coming on cam!"

sure is, but surely thats a good thing! the VVT is there to help emissions at low revs, nothing to do with the kick at 5k.

fmp_ · Mar 26, 2006

mike - indeed, just feels like its a 300 degree cam coming on timing!!

jonnyboy · Mar 26, 2006

cam profile shifts and alters the valve lift allowing more air/fuel to burn hence more power thats how I understand it, good system for pootling round getting good mpg if you drive below the 4.5krpm

Hi Fred,
If Clio 172 equipped Schrick Camshaft and right ecu map, even 172 without 4-2-1 exhaust manifold, can 172's power band kick in at 3500 rpm?

Fred@BTM · Mar 26, 2006

well our demo engine makes the same torque at 3500rpm as a std engine does at 5K (peaks at 170odd at aorund 5K)

to answer your question, yes along those lines

polarbert · Mar 26, 2006

lol I'm loving this thread. Fred said on page 1 what it is, and still everybody is talking about what causes it and vvt.

PMSL!

Fred@BTM · Mar 26, 2006

i'm starting to go blue in the face!!!

this thread reminds me of my ex!!

Lagerlout · Mar 26, 2006

What happens is, crank pressure gets up to 1600mbar and opens the fluctrum valve. This valve opens and lets the magic liquid into the baffleator which in turn dephases the exhaust flux cam capacitor by 16 degrees.

And it has absolutely nothing to do with the cams reaching max volumetric efficiency at 5k rpm.

Simple.
