Contour Enthusiasts Group Archives Forums Modifications Zetec Performance New 1/4 time...more work to do

Before I post the time let me tell you the issues as of late:
Bad cat converter
Throttle body still giving me problems after new TPS
Fuel pump- really needs to be replaced
Running real rich....will address this after the fuel pump install

Things to do:
WATER/METHANOL INJECTION
smaller lighter wheels at the track
more boost

I was supposed to have a new downpipe made, BUT it didn't happen. The cat was going to be replaced with that. I thought the TB would be working after the new TPS but nothing. I guess this is one Focus part that cannot be switched over. I will be switching back to my optimzed TB (sorry Jared). My fuel pump is still going down so that really didn't help. Gotta install that SOON!!! After that I will address the running rich by getting a my chip retuned.

After running at the track I realize that the water injection is necessary when running a Eaton blower at high boost. Car felt like it had so much more when I ran with it when it was cooler outside. I knocked .3 seconds off from my first run (car was hot) to my last run (after it sat for a couple of hours). I know the W/I will knock off a lot more time. In addition to that my 2.3 pulley will contribute some more (as it sits in my back seat).

Probably didn't help I was running with my 21 lb BBS 17's so next track day 2 steelies are making the trip with me.

First run: 17.0 at 83 mph (hot)
Last run: 16.7 at 85 mph (cool)

There is a lot more work ahead just fixing all the bugs. In all reality I expected this since I experiment with a lot of parts not meant for the Contour. Some have worked and some haven't.

Nice, keep it!

Made me feel a whole lot better about my time when another Zetec Contour ATX with intake and SVT exhaust ran 18.2. To improve almost 2 sec on the 1/4 from stock is a big deal in my book. One more second and I will hit my goal of SVT times. Something to look forward to.

How's your exhaust? Is it still stock? Do you have a race header? If not you should get one. Remember, "not enough backpressure" is a thing of the past. Get the biggest exhaust you can fit under the car, and that will help also.

The biggest problem is that you have the M45 blower and it's so weak. You need serious NA mods, like big cams and head work, to get close to 200whp, plus full race exhaust. Sucks that you can't get the Focus TB to work cause the TB is a bottle neck on the JR. What about looking at a Duratec V6 TB? Same problems with the TPS? You'll need the H2O injection to push more than 9psi, but even then you won't push more power.

OK, just saw your pic links, so you do have a racing header? But also a CAT? How big's your exhaust? You need at least 2.5" if not 3". Do you have stock cams? One of the Cougar guys installed a stage 2 cam on the intake only and got decent gains.

hector you seriously need to get that thing tuned on a dyno!! Maybe its my stick but I would have thought you would be in the 15s at least. Tuning time bro rich kills performance, just 5% too rich on my safc can make a big difference. Its gotta be just right.

Get cams and head work and everything else you can. Get fast.

Accoring to the "Drag Strip Dyno" a 16.7 @ 85mph is about 135wHP for 2900lb car.
Time to open up to a full 2.5" exhaust, get the TB working, and tune.
Good to see your working on it.
2 seconds off stock is great.
Another 1+ seconds is definately in range.
