Me and Oszy are also using them. My car is not finished yet, but I think Oszy is quite satisfied with them.

Had these in mine too. Good power increase, nothing spectacular in the scheme of things though.

Anyone ever though about trying cams other than catcams?

Also, would verniers on standard F7R cams give gains? or just a shift?
Are vernier pulleys 'typically' lighter than the OEM pulleys?

Hi mate!
you can adjust with the pulley, but without the cams....not to effective :)

the veight! yes! that was my problem too! it is not a "flywhhel" so it should be light, but all of them are look like heavy, so I decided to make one from the standard, by using alloy "middle centre"

Timing up adjustable pulleys is a job for professionals would you say?

I have no idea about stuff like that, as I have only tinkered with standard ones.

Of course, TBH i worded my original enquiry incorrectly :-k
What I wanted to know was if anyone had tried cams other then the norm (CAT, Kent, Pipers etc)

Only ever heard good things about Schrick Cams not sure if they cater for clio's. Also, iirc a company called newmans make camshafts for the Mk1 Clios. Would be good to see these make an appearance on someones car.

Shrick's are available for Clio's, I asked Fred about the details for some repeatedly to compare to the cat ones to see if they were worth paying extra for... question was always avoided though. Meh

Newman cams from what I remember weren't as agressively spec'd as the cats, cant quite remember for sure though. C&B do very good cams as well apparently. I just stick to cat because £/performance is very good.

Hi eternalife!

Schrick is very popular in Hungary, almost all the older rallye cars has this cams. The cause is that the "best" rallye engine builder (this is a small country:)) is a developer at Schrick. Unfortunately in their catalog, there is no any cam is suitable for my Clio, but they can produce anything based on the given data.

There is another manufacturer, called "dbilas" witch has a good name in business, and afeter we have use it for a BMW 318is, we realised that they are really good!
actually before I had baught the catcams, I was wanted to by dbilas, and got the following information from them :)
"Hello,

thanks a lot for your interest in our products.
(17.048.003)
- We measure with 0,07mm lift.
- The camshaft which you have choose has at 1,0mm lift 234°
- The camshaft with 280° from our catalogue has 240° at 1,0mm lift.
- The original camshafts from your car have inlet 224° and exhaust 216° at 1,0mm lift.
- You can also get 262° at 1,0mm lift. Therefore we need the max. lift which you need.
- These camshafts costs the same and are available within 2 days.

For further questions do not hesitate to contact us.

So they build also based on your wish. Actually I coud buy a half prise used catcams, so I did not baught dbilas....

my conclusion? by catcams! they are surely good for the Clio! :))

Regards,
Oszy

I have a pair of COLUMBI BARIANI ~~ Avanti Motorsport can supply them.
I have tried in vain to sell these on Ebay,but because of the mods required,I do not think people were interested. :cry:
They are full house race cams,and would require piston and cam carrier mods, :wink: :wink:
The current price was in the region of around £800 ~ billet cams

I am not 100% but I think some of the DIAC cars had them

Yess! these are good cams, my friend have them on his 17poo!

Yess! these are good cams, my friend have them on his 17poo!

The proper name is: Colombo & Bariani
I've chosen and ordered the camshafts from Acar Milano. I've overviewed all wellknown manufacturer's cataloque, the C&B is one of the "hardest" camshaft for a 17poo road car (useable with the stock hydraulic tappets, valve springs). They are Road Medium camshafts (C&B R2R.SM1), looks very good - nice flat lobe-, I can upload some pics about them if you want. The car (Clio II RS - F4R736) got a ported, skimmed head, Supersprint catback exhaust system etc, but it's not finished yet, it has to be remapped (and I think it should get a VEMS engine management, but the owner and the mechanic say the stock management will be able manage the 286/280 camshafts with 12.3:1 comp. ratio) and... although on the first RR run it performed good and is really very hard on high rpm, but very weak on low end... ok, it's a "hard" camshaft but should perform better on low end... the peak/end compression was measured: it was only 11 bar.... at this moment the compression ratio may be around 9.2-9.5:1 or less instead of the desired 12.3:1. hmm... why? So, the ported and skimmed head is not an F4R-736 head, it's F4R-7XX (I don't know exactly, my job was only to chose and order the camshafts, but it's sure that the combustion chamber is different a bit with a different stock compression ratio)... Sux... The owner is very nervous for the mechanic who has managed the porting/skimming.

the mechanic made a good job, just the 17poo management is more "electric" than the Williams, can not "study".
It need a management sistem, thats all.

I had seen that head, and it was "well done" just like mine :)

The same mecha made for me ~200hp, so I am very satisfied :))

Yes, that head is "well done" but the combustion chamber is different a bit (DaNEE said.. and he said also that Vidi was very nervous), this and the higher overlap can cause lower end/peak compression.

By the way, your car is really very good, but that 200 Hp is closer to 190-192 HP. :wink: (as I said before, I'm sceptic about that transmission loss measuring... yes, I'm bastard :P )

To be honest, I do not care about the exact figures, if not 200 but 192, than it is ok :) if you saw the graph, you can see the output from 6000-7500...I have a limiter now at 8064 instead of 7500....so min 200hp at 8000rpm :)

also if you can see the first meassuring compaire the 17poo and mine, than you can see that I perform better, so if the 17poo is 172hp, than mine was 178hp. And now + 22hp =??? how many Yanoo?? :)))

Hi Mate - you put that supersprint backbox on yet? (Video needed :wink: )
Yeah I know Dbilas - they make bodies for the E30 318is (I used to own one of them and nearly got some individual bodies put on....but had a change of heart).

I think maybe the CATCAMS are most cost effective hence why people remain with them possibly.
Would be nice to see the gains (if any) by using different cams, more so from the profile rather than just their 'mild' or 'wild' nature.

Oszy

Hi eternalife!

Actually I did not put on the Supersprint backbox, sorry :)
After I finished with the engine, I have received a very good quotation for a full system after the downpipe, by using 60mm size of exhaust system, by an exhaust specialist.
So your exhaust is still at the shelf :)

You can find some vids of my "new car" at the site:
www.indavideo.hu
search for "Williams" or "Williams200le"
or if you can not find anithing, that try to search for a user called. "1.9dt" and check his videos

I hope you enjoy! :wink:
