ABS

Ok Some may think Im crazy for doing this but I do have my reasons. I like power brakes but not ABS, but before I go tweaking I was curious if anyone has just removed the abs fuse without anything bad happening. I can not see something bad happening but still migth as well check ahead of time. I just want to disable abs, if there is a better way please feel free to let me know.

The electronic front/rear bias is shot when you pull the fuse.
With the fuse pulled the rear locks up VERY easily.
just curious but why do you not like it?
Wiseman once said

"ABS is no substitute for the foot of a well trained driver"

When I brake hard I usually (in a track environment) try to lock the back brakes up, in the situation I am referring the fronts have no chance of locking up. This modification would only be for track usage, not for daily driving... Does anyone know what the braking bias is with the abs fuse? without?

honestly we have raced an svt since 02 and would not want to do w/o abs..during a race at lime rock last year we lost it and i promptly locked rear up going into big bend..in real race conditions it hardly ever is noticeble as it has a very high threshold...only place i notice it is in heavy rain braking for 5 at summit, but that downhill stretch is a b.... anyway...2 weeks ago in our enduro at the glen it poured..the abs was really nice to have...several people commented how deep we could go into one before having to brake
I come from a 1g dsm and several zx2's I dont like abs.

Old school, I like that.

Ohh yeah definetly old school
Ok so I guess the next dumb question would be is if it fudges up the electronic braking bias... Whats stopping me from building a braking bias valve, disabling the stupid [censored] permanently and setting my own bias? Is that feasible on these cars? Would anyone here have that experience?

You're right--there is something to be desired in the feel of ABS. But the truth is that ABS significantly reduces braking distance in every situation.
we all want to think we are good enough to outbrake abs..that was very true of the early units but not today...and the abs on an svt is setup a little differently than a zx3 as far as when it kicks in...and proportioning valves are on at least churas world speed challenge zx3 and maybe leo has it on his race car....
What is the benefit of sliding the car through the turn? With the SVT's relatively low low-end torque it would not as easily recover from the slide. I understand by sliding you can get through a turn faster but you end up with a slower exit speed than just driving through the turn.

I am a rookie when it comes to roadcourse driving so my perceptions and understandings may be off or skewed.

Please educate me ecspecially since you guys are use to driving smaller cars and I have limited experience.

Sorry to go off-topic you may PM your answer if you wish.

Sort of back on topic are there any rear brake bias plugs for the SVT. On first and second generation Taurus SHO's they use bias plugs to provide more equal pressure to the rear wheels and it does not affect ABS operation. This is an aftermarket mod for them. They say the car is more stable going into the turn with them. Keeps the car flatter. maybe the SVT is not in the same catergory as the SHO but Ford could still the same thing with the Focus.

For those of you asking questions like what am i doing? why slide through a turn etc here is your answer since I am horrible at explanations. This is the one website thats got most of the idea right.

http://www.modernracer.com/tips/leftfootbraking.html

What all of you need to understand is that on a basic level the svt is like any other ff platform vehicle (that is it WILL EVENTUALLY AT THE LIMIT UNDERSTEER)

I have driven like this since I started driving, and have always driven ff platform vehicles as such through turns. This method allows you to go as fast as you can and then go further. Again not sure if anyone is practicing it but many high level ff racing is done this way. Its not so much to get the brakes to lock up as it is for me to get the weight to the front of the car MY WAY. Old school drivers will appreciate this. This method reduces/eliminates the understeer scenario, when perfected you will only lose through a turn and can accomplish this technique with relative ease and extremely light braking (provided you dont have abs)

Finally yes abs is great it is wonderful but to depend on it is to not realize the full potential of your vehicle. Learn to brake NOT using abs first then use abs, you will be that much faster and better at braking. A well trained and seasoned driver, whether through a track or road driving, will always know how their car reacts and what its limits are. Abs, imho takes a component of control away from the driver, I dislike this and enjoy knowing what my car is doing and the level of control I have over it. Again I've driven 1g dsm (horrible handlers i might add) and zx2's (respectable handlers) both this identical way and without abs. ABS gets in my way and does not give me the response nor the control I desire. The very best drivers choose not to use their abs.

if you are sliding you are losing speed..racing a low torque car (we are at 145 t/155 hp at wheels)requires conserving as much speed as possible through the turns..
IF you are racing... and driving the vehicle correctly.... there should not be A SINGLE point where you are not flooring it and at or above 5k rpms... this negates the problem of low end tq. When I go into a turn i make sure to ALWAYS be at or above 5k rpms. which puts me into the peak of my cars hp powerband well out of the range of the low tq of the vehicle. The svt was designed for that high power band. and is equipped with a rev happy motor that welcomes 5-7k rpm turns

Zoom
no doubt..the only time we are below 5k is when entering or exiting the pits..our rev limiter is removed (thanks ray!)and we run a very narrow powerband..usually about 5200 to 7800 rpm, especially on tight courses like pocono north where the only time you see 4th and 5th are on the speedway section..that said weight to torque ratio is still a wee bit low in an svt..or as techmeister rob always said..you chose to build it..in our class our main competition are very light, 2100 lb second gen rx7s...not much torue either but 450 lbs lighter
IF you are racing... and driving the vehicle correctly.... there should not be A SINGLE point where you are not flooring it and at or above 5k rpms...
That is wrong on so many levels. What about when your left foot braking or varying throttle input to keep the tires from spinning? And I don't know about where you race, but not all of our tracks let you stay in the powerband. You have to sacrifice some or you'll find yourself with a few wheels off. The SVT ABS is very non-obtrusive unless your trying to drift the car or push super hard in wet/bad conditions, which is why I wonder why you need it gone so bad.

and since i started racing in 1970 in a vee, i raced many years w/o abs....and set up right,an svt is not at all a "push" car...even in very high speed turns like 9 and 10 at vir full or the bus stop at the glen we get no push per se...of course we did do a wee bit of development on squirt..
Ok let me see if i can do a general explanation....

The idea is go in with the pedal floored (in the proper gear) (if you do this your exit speed will still remain high) you will know when the car is understeering because the body will begin to tip slightly (for those inexperienced racers) and your car will feel likes its "plowing" through the turn. When this point happens you keep the pedal floored and lightly press the brakes until the car starts to aim the way you want. The idea is when you brake you shift the weight to the front of your vehicle, when you accelerate you shift the weight to the rear. If, in a high speed turn, your car is understeering the way to fix this is to shift weight, while accelerating, to the front of the vehicle (where the vehicles drive wheels are. The front brakes wont lock up (your gassing the pedal). The only minor side effect will be a MINOR MINOR slide. i have performed this in the svt (with abs
) at 90 on a hairpin by my house. the vehicle will do a smidgen of a slide. What happens to recover from this slide is when you feel the vehicle aimed the way you want to.... let go of the brake (hence the reason i said lightly press it) Theoretically look at it guys... ff car of course the rear brakes are gonna lock up nothing is there, when you let go of the break (abs or not) because you STILL have the gas pedal floored the rear end will unlock quick and you will have held full throttle through a turn with ALOT less braking than you usually do. I have never braked before a turn with this technique. Again don't take my word for it try it. The entire prupose is not to slide and look like im driftin or anything the purpose is to put the weight in mmy ff car where it is MOST IMPORTANT in a turn on the drive tires (in our case the front) No one is questioning the svt has low tq but going into a turn fast at full throttle doesnt need low tq.
