adjustable pulleys?

[Kenned4200]

Is it worth getting these over the std vvt setup?
And what benefits are there?
Would it be both the exhaust and inlet you change, or can you do with just changing the inlet?

 

[Fred@BTM]

with stock cams?

 

[Kenned4200]

no its with c&b's

 

[stan*]

yes Catcams manufacture them.

depends on the spec of the cams really....wilder ones you tend to ditch the vvt and have fixed lift@tdc.

 

[Kenned4200]

well c&b sell them to.

 

[Kenned4200]

bump

 

[Fred@BTM]

what cam spec?

 

[Kenned4200]

The only one c&b sell for the 172.

 

[stan*]

Sorry pal, not many people are going to go to the effort of googling them for you, so if you want help, put the cam spec up.

Plus, If c&b sell them for this engine, and they only list one camshaft spec for this engine, would this not suggest as a camshaft manufacturer they recomend the use of adjustable pulleys??

and Stan is right Kenned, these cams are made to run on standard situation (probably no benefit to be had with the pulleys)

 

[Fred@BTM]

plus you can't run adjustable pullies with them

Model with phase variator

[franx]

Kenned , your being a bit silly here

You have contacted Mauro at ACAR Milano and every time someone orders a product from them they say the same thing ; "we can also deliver adjusable pulleys, they are not compulsory for the fitting "

Did he also mention the valve springs ?
He is just letting you know what other products they sell, advertisement !!

And what the guys above are telling you is not "bull" it's fact

 

[Kenned4200]

and Stan is right Kenned, these cams are made to run on standard situation (probably no benefit to be had with the pulleys)

- Where does it say that they are ment to be with std situation?

- no one has answered my questions yet.

And ps, i dont know how to quote.
pps, sorry for the spelling.

 

[stan*]

Yes, it's been answered, it depends on the cam spec, you havnt given details of this, so how do you expect a more definitive answer??

 

[Andyman]

Cam Spec links in post number 10 ?

 

[sideways danny]

dont need adjustable pulleys to dial in cams, even keeping the dephaser. Catcams make a tool for it, think sodemo do too. It's basically an adjustable locking tool

 

[stan*]

^ exactly. I made my own

 

[Kenned4200]

One of the main reasons i considered buying them, was to get rid of the dephaser pulley, so i dont have any future problems with that.
But how would that affect the enginge?

 

[Andyman]

No idea where this mass concern comes from over the dephaser pulley.

 

[Fred@BTM]

bit like the panic buying that goes on if we have a bit too much rain! LOL

 

[Kenned4200]

Oh trust me.
I have seen what a broken dephaser can do to an engine.
A laguna 2 1,8 16v had just had a head job done. When the car was fired up, it bended all the valves AGAIN. Thats why im afraid of it happening to my engine when i get cams in.

 

[Andyman]

^^More like someone didnt do the job right not the actual dephaser being a problem.

Never read of one dephaser issue on here other than noise and the conclusion from the experts seems to be how can it fail anyway...

Its not even on the Renault service schedule iirc

 

[Kenned4200]

Well, it was a cotec from renault.

 

[Fred@BTM]

from from what i've seen it is impossible for a dephaser to "collapse" they'll get noisy, but won't fail completley, its not possible
