Technical best camshaft

[blitzen]

Hi girls and boys,

I'm looking for the best performance camshaft for my cinque.
What I have:
1242ccm block
34mm trottle body
induction kit from gsrengineering
2" 4-2-1 manifold and exhaust
what I'm looking for:
max power between 5500-6000
nice fat torque around 3-4000
drivable in the city
which cam is best? it is so hard to find the right one. 280degrees only shows only how long the valve is open but not how fast it will open or .....

Visit the site www.c&b.it or www.tecnosport.it ! They are the best manufacturers for those part I think

Hi Enzo,

somehow I get an error notice when trying out c&b.it and get to a software company when trying tecnosport.it

Forget the previous post...the correct links are below:

I think they can help you!

Enzo thanks for the links.

Now I know where to get cams, but which one? I don't speak italian and even if I would I couldn't make much sense out of the numbers.

Marc,

Where did you get the throttle body, if you don't mind me asking?

I got the trottle body at "Autohaus Köster" in Herford Germany. They had different sizes 32-34-36-38mm. You can get them at www.bielstein.com too. (there should be a british importer too)

Those details could match your request!

Enzo,

thanks for the details!
But I think there is a misunderstanding. I can make out what a few of these numbers say, but it's only guess work.
I know about 280degree cams etc, but here are 2 numbers i.e. 280/268 ....
Can anyone tell me what the different characteristics of the cams should be? Is the "coldest" cam hotter than the Punto 75 cam, or is it better without loosing torque at low/mid rpm?

Enlighten me!

 

[Enzo]

Allora... I think you know an high performance camshaft allows the air to fill the cylinders better than a stock one...but this occurs at high rpm, so you'll loose a bit of torque at low revs!For more precision the torque's peak will "move" to higher rpm and the max power will be positively affected ... You can't get this and that !

The two numbers you see are referred to the duration (in degrees) of the intake/exhaust phases respectively!

Enzo,

I'm aware that the "hotter" the cam gets the more the power is transferred into the higher rpm band.
But as you know there are a few things that might restrict the performance of a stock cam (emission/noise/tax restrictions) so that a well constructed cam might give more power without loosing any at low rpm.
The first 2 cams you've mentioned (or paste) are looking right. But I was told that you can't even trust the degrees as companies measure different.
So I think I was more looking for first hand experience.

Sorry but no experience in this field[xx(], even if I've been looking for a performance camshaft to fit on my 1.0fire!Btw I think the C&B brand is reliable for quality and for the data they declare...lots of people here run pleased with its products!You could visit an italian site on tuning, called www.elaborare.com and then search for the forum...or directly call the factory, I assume they speak english and are cordial, too.
