I do not recall the spec's for the focus zetec cams. But I do recall it was posted here before. If no one can answer, then you should try a search.

As to what cams will work best for you, It all depends on what type of powerband you want to have. To best answer your question on what cams will work for your needs. You should do a search in Zetec Tuning. You'll turn up alot of useful info, that has been talked about over and over again.

Here's a list of some different cams to look for:

Crower
Crane
Ford Racing (produced by crane but are different)
Kent (Focus Sport)
Kent (Batinc.net)
CAT
Esslinger

Hopefully this will provide you with alittle insight.

crower and crane's site list the stock specs where the rest of their cam spex r located.

Hey guys! I saw where both websites listed the stock specs for the cams. However, they are different. So I was just curious as to which one is correct. Thanks!

 

they both r, just that each company has used 1 of a couple different reference pts. look at them in relation to their aftermarket cams to see what you gain in lift duration overlap etc.

A number of people have measured cam lobe dimensions with results varying by +/-1 deg and +/-0.002" lift. These are typical measurement variations

The specs I have are:
Intake: 206 deg @ 0.050 and 0.353" lift
Exhaust: 205 deg @ 0.050 and 0.342" lift

Use these numbers (or other published values in this range) as a baseline for selecting higher preformance cams.

 

i have another question... y is it that 1 company will list a 210 cam as stage 1- idle to 6500, and a 220 as stage 2- 1500-7000, and a 230 as stage 3... and another company will list a 220 as stage 1- idle to 6500, and a 230 as stage 2- 1500-7000...

 

Because "Stage 1,2,3" are just terms. Kinda like how a Nike size 9 and a Reebok size 9 aren't the same size.

 

stage is relative only to individual manufacturers.

Stage 1 is most mild... the higher you get, the more aggressive it gets.

Crower now has Stage 4.. their new stage 2 is more aggressive than their old stage two.... now hows that for confusing?

 

thats not what i meant... i know the bigger the duration is more agressive, but how can company A say a 210 degree cam is good for idle to 6500, and a 220 is 1500-7000, yet company B will say a 220 degree is good for idle to 6500 and a 230 is 1500-7000... the degrees of the cam aren't changing, just the operating range...
