ST307bhp

Just thought I would share one of the FFOC members latest mods.

I know some of you will be thinking that for 5k or whatever it cost you could get a jap car etc etc!

But this is a nice increase from 170bhp! All credit to powerengineering again after the Turbo conversion last year to another ST.

Nice, that is one very nice torque curve

great advice · 6 Mar 2006 at 20:36

He could have had 4 wheel drive and a cossie engine for that cash!! Still a nice set of smooth curves though

5k would be cheap for that kinda of increase, bit dodgy in 3rd or less I bet

Why do people always say this? I bet you have never been in a powerful front wheel drive that has a decent suspension setup?

I say it because I get wheelspin with half the bhp but I'd be glad to be proved wrong, still nice to have the power in reserve either way.

The famous Evo U turn on the focus here -

Later 1980's hot hatches traction seems to be the basis of it.

Its a very impressive result to say the least.

Just need to save the pennies now to get one myself

Thats an awesome power delivery if that print out is accurate.

Suspension has little impact on the fact that weight distribution moves to the rear, making the fronts lighter under hard acceleration, thus inducing wheelpsin. Every car in the world will experience that.

My 190BHP celica has a real hard time laying its power down in anything other than dry conditions in 1st and second - especially w/out TC

If you have solid rear suspension then there will be no weight transfer to the rear, so yes suspension does have an impact.

My Rover puts the power down and thats a car that 'doesn't handle'. Im sure the Focus would cope pretty well.

Yup thats how you sort this out, put stiff suspension on the rear to stop the front lifting. If your still putting too much power down then folk will put a wheelie bar on the back for when going down the 1/4 mile, not to stop you doing a wheelie but to keep the front end down. a stiff rear has the same effect but to a lesser degree

but still more than enough to cure wheel spin on a 300bhp focus.

Maybe it should be changed to "lots of power through the front wheels is fine if you have a few replacement spines"

Jonny69 · 7 Mar 2006 at 12:25

No bad power. Funny how that engine block looks almost identical to the old Anglia and crossflow engine it was based on, never seen one before. All the holes and waterways in the same place.

Just out of interest what cars would you put in that catagory? My most recent experience of powerful FWD cars was an 05 Civic Type-R and I couldn't believe how easy it was to spin up the fronts in the dry.

I get wheel spin in my mum 90 bhp fwd Subaru L series from take off and even from going from 1st to 2nd

i obviously expected that, but if you go too stiff for a good take off your handling through the corners is going to be drastically diminshed, and lead to a heck of a lot more risk of a spin.

Also, the amount of stiffening required to achieve a good take off in a FWD would make the ride ridiculous, so i'd hardly call those 2 limitations having "sorted suspension"

Theres generally a reason why cars go 4WD/RWD above ~250BHP

They only have a open differential though and are pretty poo to be honest despite good suspension.

I didn't mean that you need solid rear suspension to allow Fwd to get the power down, just good suspension and poly bushes will help as the suspension isn't flapping about and affecting toe angles etc. Certainly stiffening the rear will help as well as softening the front.

Anyway it's not really the power through the front wheels it is the torque that cause's problems

goes without saying, but doesnt alter the fact that, whilst its mightily impressive, 250+BHP (and the torque produced) is too much for FWD

P6000's are the manufactures chosen tyre for that i think which arent the best. with eagle F1s i find it grips much more and hence less wheel spin
