Hi there just thought I would post on here to see if Anyone could give me some ideas on how I can get some more power out of my focus, I have got a in closed ramair air filter and scorpion cat back . Thanks Ben

 

Hello and welcome to PF. The ST170 are a good car.

 

Not the best yo extract more power though unless you bolt a super charger to it

 

I right would it benefit from a decat and also would a decat have an efect on the lambour sensor thanks Ben

 

As above, they're not easy to get more from and are regarded as being pretty much as good as they can be from ford. Some have reported losses after mods. OBD tuning like dreamscience can make them more driveable and iron out flatspots.

 

Spend your money building a turbo lump or as I've said, look for a second hand supercharger kit

 

Single mass flywheel conversion, would be my first port of call, for the rest I would suggest will pedley racing as they have done a lot of work with the ST170

 

the st150 as it should have been called has always been underpowered

 

Wouldn't agree with that, when I had mine I RR it and it was around 170.

Tho if you don't pull the for the traction control it stopped the VVT working which results in shite figures which I discovered after getting pissed off at it being under power

 

I had a Bluefin, decat panel filter and a exhaust on mine.

Not a lot else more you can do without spending a fortune.

As said a single mass flywheel is a good investment. With the dual mass in my old one you couldn't really launch it as the clutch jammed in.

 

on the dyno as std mine was 148 and mine was not a tired example either and was low mileage after all the above mods I reached 168, with high ins and running costs due to terrible fuel economy its simply a gutless cheap focus, and btw very few dyno operators know how to fully set up their machines so false generous readings are way too common unless you use serious pro's like MSD

 

Decat, exhaust cam vernier and a remap from the likes of Dreamscience Or Evolution Chips would give a little more power. Those are the only "sensible" modifications you could do. You aren't a million miles from MSD so I'd go there with an exhaust cam vernier pulley and let them set it up on their dyno plus get them to install an Evolution Chips map and tweak it to suit your car.

 

fit a decant system from the cat back k&n typhoon air filter and 67mm CFM throttle
body and you will be running 185 that's the mods i fitted to my 170

 

Thanks for all comments going to look into it when I get some money.

 

My st170 has a decat, costom cat back, KnN pannel filter, omex launch control and mine is running 176 at the wheels

But the best way to get power is a good service, and even timing belt change

 

Hi you no your decat does this efect the lambor sensor, and is t much louder

 

thats a very poor figure. i think a lot of 170s suffer from dodgy imrc which kill the power.it doesnt always bring on the eml as iv had problems with it and it was guttless but no light on.i knew straight away what it was but an unsuspecting owner would not have a clue why they car was so slow.

176 at wheel is a dreamers figure. you either got conned big time at the rolling road or you meant flywheel


dont bother with a decat. you will see no power from it

 

the previous owner had it set up at jamsport and the printout said 166 then once I took ownership 5 weeks later and after having it fully serviced with belt changes etc took it to a pro garage who said their figure was iincorrect as they saw errors in the technicians set up of the dyno hence generous reading in first place

 

it must have been pretty gutless to drive then? surely something was wrong for that low a figure?

i can see 160s being the norm but 148 is surely a faulty car dont you think

 

Factory figure iirc is 168ps at the fly, 176hp at the wheels is a bit generous from essentially just an exhaust and filter, there are people that have done every conceivable n/a mod and still only shown 5hp over factory standard!

There was talk that early ones were only showing 150ish and the later ones actually achieved close to the factory quoted figure.

 

ah ok i didnt know that. mine are 53 and 05 so later models.

 

What are those sports cats like are they any good?

 

ST170s don't go any better with a decat or a sports cat its not worth wasting your money on them mate that's why i never fitted one to mine

 

Oright ok thankyou, you know on the cat my bracket that holds it has croed and is raterling what could I do

 

the car drove great but never set my world alight, and knowing so many top tuners I had one look into it checking everything and mine was a 2002 model but when you pay to have the car uprated to just reach the power figure quoted by ford in first place was silly so combining that with stupid fuel economy of st170s I had enough and sold it, best decision I ever made thank god

 

My 170 was dynod at 161bhp a couple of weeks ago.

Ive been speaking to will pedley quite a bit regarding my car and he said the best thing was the k & n typhoon induction kit, exhaust with decat, vernier pulley on the exhaust cam and a live remap. All that makes the car very capable, doesnt cost a shed load and will give u about 185 - 195 depending on the health of your engine and how good the place is that does the remap

 

They sound nice with one tho

 

Does a decat give anymore power or is it just sound ?

 

It is deffo 176 at the wheels, I got it on the RR at jamsport the day after FF on my way home, and I know it dosnt make much difference but the car only has the front seats in

 

take jamsports dyno figures with a pinch of salt as they are always generous as mentioned in my other post above

 

176hp at wheels would be close to or even over 200hp at crank. Doubt it very much.

 

I'm not into internet arguments so don't take this personally but i'm struggling to see how a panel filter and exhaust(even with decat) is giving you whats roughly 25+hp increase over standard? If you go with say a typical 15% loss from fly to wheel thats over 195bhp at the fly without verniers, remap etc..

Panel filter and exhaust would give 10hp on a good day and the launch control and stripping will only make a difference getting it down the road.

 

based on that statement alone id never go to jamsport. if its 176 at wheels then im a banana. i do believe you were told its that power so im not accusing you of lying in anyway but you were 100% lied too. you should have ripped the
printout up and asked them to eat it.
