Speed Costs Money

How Fast you want to Spend :)


open your wallet and youll be surprised how fast any car can go !
Yeah theres alot of info thru out this form so enjoy reading and question everything.
there are several air intake kits including:
injen
K&N
AEM
FSwerks
Steeda
and cat back exhaust systems including:
Ford Racing
Magnaflow
Flowmaster
Borla
available for the Fiesta to increase power.

There is not One mod that you will see any sort of substantial increase. But if you add a few different mods that add a few horses here and a couple there, you can add 10-15hp before you know it. The biggest thing is reducing the restrictions (no, not talking ecu). Reducing the weight will reduce the restriction on the engine (reducing the engine load), for example. Weight reduction will not add hp, but rather, free up the hp you already have. High flow intakes reduce air restriction, performance plug wires, etc.
And ols saying goes" If you want to go faster it take cubic inches or rectangular dolloars".

A car magazine I subscribe to did a CAI and cat back exhaust on a 140 hp car. They gained 4 HP on the dyno.
Nothing short of an engine swap is going to make this thing any faster. It's an econobox, know what you bought lol.

Mostly this.

But also keep the wheels and tires light.

What she said!

Iceracer is also correct.
However I heard it as " The only way to beat cubic inches, is with cubic dollars".

If I am lucky, I will have spent about $5K to maybe gain 30HP.

i believe that the best way to get a fast car is to buy a fast car

I disagree with that statement.

This motor is a Masterpiece! remember it is a just 1.6L of displacement, with 120 hp,

just 20 years ago, Turbo charged motors were getting that much hp/L

the motor does what it is designed to do... perfectly.
Dave,
I think you got the quote right.
It's been a long time
in the UK you can get the Mountune MP140 or MR155 kit that improves the Fiesta 0-60mph time from 9.9 to 7.9 or 7.5 seconds.
Fiesta - (2008-onwards)

They will not sell this kit outside of the UK.
I have asked.
They also require that you have the PCM re-tuned, something that cannot be done to the US cars.

I now have (or ordered) all of the parts of their kit except the tuning.

I compared the stock intake versus R2C CAI, in terms of speed, the results were almost the same and they are governed by the ECU. The maximum speed I was able to get with R2C CAI was 118 mph downhill, and on a flat road was 116 mph in fourth speed. When I evaluated the acceleration 0-60 mph, after several trials my best score was 9.5 seconds with R2C CAI. 0-60 mph 9,5 sec Ford Fiesta 2011 SES with R2C CAI - YouTube Unfortunatly I didn't do the same test with the stock intake so we can't compare. In my opinion, 0-60 mph lower than 10 seconds is very decent for a 1.6 L engine. This results should improve with a new exhaust system but as you know, this depends of many factors mencioned here.

Yea...it's designed to be economical and slow. This is not a performance car, it was never designed to be and never will.

The Ford Fiesta makes 120hp with a 1.6L engine. That is 120/ 1.6 = 75hp/L

20 yeas ago you could buy the 1993 Supra 2JZ-GTE, 1989 Skyline RB26DETT, and 1993 M3 Euro S50B30.

The Supra made 276 (Japanese spec) and 320 (American spec) horsepower out of a 3.0L engine.

The Skyline made 276 (Japanese spec, gentlemans agreement) horsepower out of a 2.6L engine.

The M3 made 282 (Eurospec) horsepower out of a 3.0L engine

All performance engines yes, but all makeing a lot more then 75hp/L 20 years ago. The Fiesta's engine is a good engine. Just not a high preforming engine. It makes plenty of power for its size, gets excellent fuel economey, but is not a fundementally better engine then the Japanese or Germans could produce 20 years ago.

As for your last statement, yes it does do what the engineers designed it to do perfectly... Get lots of fuel economey in a small econo-box.

Now you are comparing a 1.6L to a 2.6L and 3.0L.
I don't believe that is a valid comparison at all.

If you are saying that it took 2.6L or 3.0L to make the same HP as only 1.6L today then it validates the point that Fiesta has a great engine.

If you read his post, is a perfectly valid comparison. Saying that this motor is great because it's capable of 120hp for its size is silly, that's his point. Small motors have been making good power for decades, the motor we have is nothing special in that department.
