Best cams

Catcams 421s IF and only IF you have a mapping solution that can sort out the idle. You may get away with a high idle adjusted on the throttle body as it's a ph1, but the stock ECU struggles with the pulses in the plenum on wild cams.
Catcams 428s if you want a simpler solution.
Personally I'd change the ECU first, I've seen comparable gains from just an ECU to cams

Was looking at a map aswell, as some of you are aware the 172 engine will be going into my megane coupe. Got the new cam belt and kit so i was debating doing cams whilst im at it. Could i map a standard ecu? I take it the car wont be ok with new cams and no mapping solution
ITB'd MK1
you wont get any real benefit without mapping, it'll be wasted potential, and not really for the engine.
I dont hold a huge amount of faith in the stock ECU from a modification perspective. This statement WILL cause an arguement
i've just done a car with 428's and it did 26bhp (192.8 at fly) gain peak and pulled 160lbs/ft
same rollers a throttle bodied car with cat 420's did 202 peak with (from memory) + about 10lbs/ft (it was running omex)
not bad for cams, inlets and 182 mani
(stock ecu remapped to suit - hi danny!

I have Colombo & Bariani cams, nasty wild , and running very nicely on the stock ecu. Idle problem was there but solved by turning it up a little . Henk Fastchip made them run cherry

credit where it's due, Henk is pretty good it seems, and honest about limitatons too.

I am thinking of cams, and are very undecided between 428 and Colombo, but now you mention the idle issue I started thinking again, what is you idle at?
You sent me a graph and there is more torque every where in the rev band, but my car is a daily driver and in lots of traffic (Mexico City), so wonder how anoying could be a bad running in low revs and idling
Cheers!
Looking into a cam change myself.
Problem iv got is cars running 172lbs/ft dyno'd on RS Tunings RR but looking at other folks torque figures using different cams, most folk get well under this figure so dont want to install something thats going to loose me power. At a loss of what to get..
My understanding is:
420's are basically stock
421's are pretty wild and kick in from 5k.
428's best all rounder
No idea of any of the other cams

No idea. Can only put it down to being well mapped and the right combintation of mods :S
By looking at a graph can you tell much info regards to where the cams kick in and tail off?
You get your standard ECU mapped. Sure you can get sent a generic map on exchange but might be wrong. As for a place, not sure where is nearest to you.

Im looking at the exact same thing. Cams are going in during the winter and I cant decide what path to take. Decided to go for 428's but now when its time to order they seem a bit boring since they are almost stock.
I guess 421's, Schrick and Colombo are almost the same? All just about doable with standard ECU. But are the gains over 428's worth it?
Were can I buy Colombo Cams at a nice price?
I also wonder what cams and increased idle will do to the CO2 figures? The MOT or what you call it in UK are hard as hell on the CO2 in Sweden.
C&B's have the nicest idle and best torque overall. For a street car the nr 1 choice.
With the right aux. mods you can have exactly the same torque & power as a stock 197 Engine. Provided your engine has little leakage and a calibration to match.
All you need then is a Sadev sequential

Haha sadev box would be sweet as h*ll.
Actually my car goes very well already, at least in my opinion. RSTuner 116kw@6300rpm and 188Nm@5400rpm (1200kg and drag 26kW) But maybe thats a normal figure I dont know.
But IMO it would be wrong not to install cams when belt is to be changed. Guess Ill have a look where I can buy Colombo Cams then. You will be the one to write the custom .cal so I'll take your advice
Will these cams be ok with standard springs and retainers?

we've got the CatCams on a club deal at the moment

I am probably the very first user of C&B's from CS. You will be extremely pleased with the results as long as the cams are coupled with the Henk's full custom map for C&B's.
C&B's are billet cams and of very high built quality, They have different profiles in their stock, the current one advertised on their website is the most updated one. As far as I know the profile was updated three times since 2002.

Okay nice info there!
Where did you buy yours? Wrote a mail to "Acarmilano" to see what they could offer.
Car will be mapped by Henk!
RS RIP
still waiting for your call mate, how is your vacation going?

I wrote a mail to Mauro yesterday. Just waiting for his reply and confirmation for the price then I'll order. I must say that Henk's words was of great importance for my choice. Listen to the pro's.
However I would like to see some figures for CB cams on a 182.
Also if some one of you could post a RStuner print of the Injection Duty Cycle on a full load run with CB cams I would be very happy. Did one run yesterday up a hill to the limiter on fourth gear and I had 95% @ 7250rpm and 100% over 7400rpm. It also feels like the car looses a bit of power above 7000rpm. Ive heard there it no way Ill max out the injectors but it still worries me. Is RStuner figures not to be trusted?

:dead: have been working and painting my parents house and working + working...
today will be my last shift and i'm off to Izmir tommorow
RS RIP
even with my cams i can feel a bit of "flat" above 7000 rpm. But then again i can remember in my case that it's mapped with VVT disable at around 7000 .
182 trackday racer
Why is that?
421's might be ok on a full ITB'd up Clio but from what iv read they kick in at 5000rpm?? Ok for making good peak power but far less driveable and probably less ''quicker'' feeling in everyday conditions on a stock single TB set up.
