That says they got almost the power and torque of a Cobb 93 octane tune with 91 octane gas in a stock car.

They either got a very very strong example or the dyno's correction factor is off.

Finicky or not the Focus has a huge power advantage, hopefully we will figure out how to bridge the gap.

Seriously, dynos are known to vary quite a lot from brand to brand.

I wonder what the speedometer read at redline?

The Focus might have a huge power advantage on paper, but the Fiesta can out perform it on the track and autocrossing. Only on very long courses would the Focus ST start to really do well, but the faster it travels on the straights, the more braking it needs to slow down. Braking is where the Focus ST can't hang with the Fiesta ST. Having been autocrossing and at the track with both cars, the less powerful Fiesta ST is far better of a performer. I would not bother trying to bridge a power gap that only exists on paper. People seem to assume the Fiesta ST is the underdog compared to the Focus ST, but that just isn't the case. Even off road, the Fiesta ST can go places and do things that the Focus ST struggles. Drag racing and top speed are really the only things the Focus ST does better, but nobody buys a sport compact for those things.

Well said!! 100% agree. My Fiesta ST begs me to take corners and when I do it feels like I am on rails.

Thanks, really good to hear of your experience in both. I have not driven both or done any track or autox driving in my Fiesta ST yet, but it does strike me as an extremely well balanced vehicle i.e. power, handling and brakes, much like a Miata in that sense. When I first read about the Focus ST a few years back I was very interested but the many later road tests that mentioned excessive torque steer and wheel hop put me off the car. Learned of the Fiesta ST a month ago, the reviews had me 82% sold and a test drive did the rest ;-)

Maybe I'm not a good example but I would like the power of a Focus ST in a Fiesta ST to make a car that can rival almost anything on the road in a straight line or in a curve.

I think it would be amazingly nutty fun.

That was an impressive read. Ive rode in a focus st and asked my friend to floor in through some turns. Hes a real good driver who is use to 500 plus hp cars and was fighting it through tight turns.

Hi eRic
Any reason you used 3rd gear and not 4th?
Hoping he said 3rd pull meaning not the first 2 pulls but I could be wrong .. not sure what gear to be honest :)

they ran it in 4th gear for all the runs. the 3rd pull/run made the most power and torque

we waited 5 minutes between runs. no tuning. just a fan blowing on it.

Not to purposely raise an old thread from the dead but... how many miles were on your car when you did the dyno runs?
