Zetec cam selection? What are people running?

I'grand am about to get my head worked, I am wondering what cams people regard every bit best suited to a zetec? What sort of ability gains people are getting? I accept been looking at Newman PH4 cams, I don't want anything also lairy so I can only run the car apartment out but I don't mind loosing abit off drivability in depression speed traffic. I plan to use the automobile occasionally for track days and hill climbing so I don't want annihilation too mild either!
thanks

Re: Zetec cam selection? What are people running?

For your needs and spec I would go with these cams

If you were running a silver top then there'southward more than choice.

How-do-you-do Mike,

Can you tell me more than about the specs of the black-tiptop (251bhp) engine you built.

Re: Zetec cam selection? What are people running?

I was a little out of touch with Zetec cams but i've recently read up on and so all and dorsum in the 24-hour interval people used to motorcar the lifter diameter to 32mm with wild cams but at present the development of cams for the zetec take moved on and there is no need to do it whatsoever more

Just considering it had 251 bhp doesn't mean it was the all-time mike said that the silverish top zetec was the best

be conscientious when selecting cams, find out what would work best for your needs.

Don't fit a race cams in a road car as it will be dreadful to drive

Re: Zetec cam selection? What are people running?

Birt
The spec for the blackness top 250 bhp steel rods,slipper pistons 12.1 pinch. Big valve caput fully ported 4.2.one exhaust manifold .
The silvery top one has steel rods,slipper pistons.Standard valves fully ported head 11.1 compression 4.one frazzle manifold.
As I said earlier on the hillclimbs the silvery meridian is a more flexible engine.The blacktop is more top finish. At Gurston hillclimb my finish speed is 99mph over the finish line with the argent summit .The blackness top is 104mph but overall the silvery top is 2/tenths quicker. At Wiscombe the times are identical.

Every bit I said earlier on the hillclimbs the silver top is a more than flexible engine.The blacktop is more top end. At Gurston hillclimb my end speed is 99mph over the terminate line with the silverish elevation .The blackness top is 104mph just overall the silverish top is 2/tenths quicker. At Wiscombe the times are identical.

Re: Zetec cam option? What are people running?

I will have a look and post them upwardly.The Silver meridian pulls from 3-7500. The black top four-8000.
Every bit Andrew said don't fit race cams if running as a road machine.

Re: Zetec cam option? What are people running?

Not to blow my ain horn but yous would see more than of a gain from caput work. I have worked one all the Zetec engines and the argent top is 1 of my favourite Zetec engines when it comes to tuning.

what sort of gains would decent headwork give on a two.0 silvertop with std cams ? (using t/b's or 45dcoe)
hope thats not besides off topic

I accept been told by someone that they got 21bhp at the flywheel...The guy didn't do a back to back dyno and he also rebuilt the engine at same time so its really difficult to requite a 100% accurate figure of the gains

Re: Zetec cam choice? What are people running?

Hmm wish I had gone for a silver top at present......Not 100% sure why I went for the black top, since I am having larger valves and re edifice the bottom end anyway it wouldn't of really made much o a difference having slightly higher mileage

Re: Zetec cam option? What are people running?

We found the silver top has better ports and can exist opened further.The silver meridian head flowed better after porting compared to the blacktop.The ports are smaller on the blacktop.
The only downside is if you want to run higher profile cams you lot need to get the head machined for bigger tappets on the silvery pinnacle

Re: Zetec cam selection? What are people running?

Hmm seems they both accept their upsides and downsides, oh well see how it goes, if it doesn't become every bit well as Im hoping for I guess I will take to start over again with a duratec
