Cams & Timing question

[shauncr91]

Hi guys, got a quick question regarding cams and timing.

I've got a set of Newman 200spec cams ready to go in my Fiesta ST and just wondered about the timing. I was always under the impression that they'd have to be timed correctly due to the longer duration and higher lift but a couple of people I've spoken to have mentioned that they'd just use the standard settings that Ford do with the standard engine, so who is right? The people saying they'll need new timing settings or those saying they'll just drop right in on default timing so long as I'm not changing the pulleys?

And while we're at it, if anyone in the north can recommend a place/person to fit them then let me know, best price I've had so far is JamSport in Northampton at £180

Pumaspeed are the ones who told me about using default timing and only needing adjustment if changing the pulleys, problem is they told me that they'll only install items which are bought from themselves which is a let down because they are a 15 minute drive away!

The car will be getting a remap to go with the cams but not at the same time, I'm going to run them for a couple of weeks first and possibly couple the map up with fitting a Cosworth inlet JamSport will be doing the map and it'll be a proper live map not a stock one.

What sort of gains does an ST get from cams / mapping then?

Back in the day I had a VR6 that the previous owner had spent £1k on getting cams & map done....the dyno only showed a 10ish bhp gain iirc. It did make it feel much more aggressive than a standard car mind you

Standard the cars have around 147, mine is running 173bhp with a full milltek decat system, K&N and remap from previous owner, Mountune cars hit 185bhp with that plus cams but mine are slightly better spec than the Pipers they use and will be mapped better for my car so should be able to get 190

As you said though it isn't just the numbers, they change how the car drives immensely and after 4.5-5k they just go berserk

Quite sceptical about those numbers..

But anyway, adjustable cam pulleys and full setup on a dyno would probably better than putting new cams in and praying.

The results have been proven many times by people who've got the same mods, here's a snippet of the STOC leaderboard:

What kind of benefit do you get from the pulleys? Not really something I've looked into.
