Contour Enthusiasts Group Archives Forums Modifications Duratec Performance Duratec V6 cam specs

Whwere to find good photos of Duratec Cams?
And all critical measures? For both cams intake and exhaust.
Thanx.
I´m going to send those measures and all other information about duratec V6 to several Cam makers if they will make some tuning cams for our beloved engines

IIRC this is the SVT Duratec cam spec.....

Cam specs @ seat to seat
Intake Lift @ valve is 7.38mm
Exhaust Lift @ valve is 6.99mm

Lobe center- 108*
Valve overlap- 62*
Intake duration- 278*
Exhaust duration- 278*

Edit: Actually this isn't the SVT specs......but a HP duratec cam spec. I've heard of the lift going as high as 10mm on some "hot" duratec cams. I have the degrees where the intake and exhaust valves open and close, ect if that'd help....

The specs on the cams are:

*98-00 2.54L & 2.49L SVT*
Intake Open = 18 deg. BTDC primary & secondary
Intake Close = 52 deg. ABDC for primary
Intake Close = 60 deg. ABDC for secondary
Intake Duration = 250 deg. for primary
Intake Duration = 258 deg. for secondary
Exhaust Open = 61 deg. BBDC
Exhaust Close = 21 deg. ATDC
Exhaust Duration = 262 deg.

*95-00-2.54L & 2.49L Non-SVT and 95-99 3.0L Non Lincoln LS*
Yes, they use the same cams. Only LH 2.5 Intake is longer for accessory drive pulley.
Intake Open = 17 deg. BTDC primary & secondary
Intake Close = 47 deg. ABDC for primary
Intake Close = 53 deg. ABDC for secondary
Intake Duration = 244 deg. for primary
Intake Duration = 250 deg. for secondary
Exhaust Open = 67 deg. BBDC
Exhaust Close = 13 deg. ATDC
Exhaust Duration = 260 deg.

*2000-3.0L Non Lincoln LS*
No primary or secondary. Head is not split port.
Intake Open = 4 deg. BTDC
Intake Close = 48 deg. ABDC
Intake Duration = 232 deg
Exhaust Open = 56 deg. BBDC
Exhaust Close = 12 deg. ATDC
Exhaust Duration = 248 deg.

Max Lift for any cam = 9mm

Thanx dudes!
Now I´ll need to find some pictures
Or good drawings.

Jiihaa!!!

No I did find some cams for Duratec 24V engine

there is e-mail I received:

Hello,



These are the available profiles. They are all hydraulic profiles to be used on factory cam followers, springs and retainers. You can make intake/exhaust combinations as you like. Please indicate the application if you would like some advise.


best regards,

Any one interested?

Those cam specs do not add up???


Do you have a link or site we can get more information from.

For instance some extremely important specs like Valve Timing!
If we could get the valve points then those specs would have some meaning.


No dual pattern cams??? (Like the OEM cams that take advantage of the dual runner manifolds)


Are these hollow billet like the stock cams or heavy solid cams?

Their site does´nt have more info.

But I´m waiting for answer to my e-mail.

There is cut of one email:

Dear Sir,



We are almost 100% sure we do have the camshafts for your engine. We already provided race cams for Ford 2.5l

V6 24v engine with roller followers (Belgium touring car championship). This engine was mounted in Ford Mondeo ST220 model, maybe you can check with your local ford dealer if it is the same, but as far as we could find out, it can only be this engine.

Please indicate the application (fast road, rallycross, �?�) and further engine modifications to choose the best cam profiles for your application. For pricing and delivery, please contact our main distributor.

Dear Sir,



I think those values cannot be more clear than they are in this table. Moreover, none of our �??competitors�?� will provide so many data. The profiles are fully symmetric, so you can easily calculate the valve opening and closing points. The optimum valve timing centreline should be found on the engine dyno and depends on other engine modifications, so for optimum result, you need adjustable pulleys. If you use stock pulleys, the valve timing centerline should be the same as OEM centerline. Please do not compare data measured on 0.1mm (like your OEM specs) valve lift as they are worthless due to measurement errors. The table gives the different profiles that are available, so you can mix them as you like. On the other hand, you should keep in mind that the two different profiles for the two intake valves do not correspond with the two intake runners. The two valves work the same over the complete rpm range, the long runner only work at low rpm, the shorter one at high rpm (shifting point will probably be around 4000rpm). If you want good performance cams, it is the best to have two identical profiles on intake and two (other) identical profiles on exhaust. The cams are solid steel billet. The information is not yet on our website, it will be on our new website which should be released in September.
-------------------------------------------------------------

So figure it out.

I did ask is it ok if I byu just intake cams and leave orginal exhaust cams intact:

Hello,



-If you will purchase only one camshaft, it is the best to order the intake cams with profile #2437. As stated in one of your last mails (the mail with the OEM cam data), one intake cam is longer for the extra drive pulley. You will need to take both intake cam gears off by using a press, and then modifying them to adjustable gears which can be fixed against flange of your new steel billet intake camshafts. Once again, we do NOT supply the cam gears.

-The OEM exhaust profiles should work fine as you already modified your exhaust system.

-Please keep in mind that the cam should be installed by a professional engine builder. Probably you will need to have a new ECU mapping, although some engines can easily adapt themselves to new mild road cam profiles so maybe you are lucky. We do not have any information on OEM ECU behaviour at this time, but remapping always gives far better results.



Best regards,

Okay so no dual pattern cams to match the dual runner intakes. (They definitely SHOULD have skipped the crap about it being better to run 2 indentical cam patterns. Without the primary lobe & runners the engine would be a dog below 4000rpm. That's just asinine marketing BS talking!)
They are all solid cams. (okay not a shock, but should make them MUCH cheaper!)
No cam gears. (This will be a big PITA unless someone makes some adjustable cam gears! )

No valve timing specs either. (I.E. the numbers they gave ARE pretty worthless) I would NOT touch a cam without knowing these specs!!! Duration specs mean very little at all without knowing the valve timing!

BTW - the cam they recommended is not even as long duration (only spec they gave ) as the stock SVT cams. Either one!

...and since I'm nit-picking... A ST220 with a 2.5L engine eh... That must be rare...
