Am I right in thinking, Another aspect is surely the exhaust timing - newmans delayed exhaust relates to more power in comparison to pipers?Originally Posted by MAXIBOY

For the record Catcams dont do 264deg grind.
As for comparing those to above, your only showing duration from 0.1mm....as I said to better see which is more "agressive" you need duration between another lift point...usually 1mm.
yes, the retarded timing figures will aid peak power in theory, BUT we dont know how the profile compares, so you cant give a definative "yes this is better" answer.
In any case, its always a pay off between performance and idle stability whilst your on the OE managment. Jays idles nice because the cams arent very wild, and the timing figures may have been altered to aid idle at the cost of peak figures.
If you were wanting, to say, purchase the newman cams for example (264 dur) what else would you need to buy along with them?
i.e. would you need the vernier pulley's as well and springs, etc.... or can you simply buy the cam shafts, put them in and away you go?
I'm guessing you'd want to buy a new cam belt?
Cheers.

so how 'wild' a cam is and 'timing' are too seperate things.
so u can go with a mild cam timed more aggresively or a wilder cam timed more conservatively, which set up would be better to go with?
lol fair point , just trying to find out what factors affect what
When i say timed in right, I mean what is recommended by the manufacturer. Of course you can advance or retard depending on what you want, but it's normally best to stick to the setting recommended. Also... isn't timing in some way determined by the ECU on clio's? (timing of the spark I refer to).

i would say a wild cam timed mild.
if you have a mild cam timed wild thats your limit.
if you have a wild cam timed mild you can always time it more aggressively when you get bored/track days/never
