Terrible 1/4 mile times in my SVT
 
1 Attachment(s)
I took my focus to the track today for the first time, and needless to say I was pretty disappointed in it. I had traction control switched off and it just bogged down terribly at launch.... Is their a trick or something to get around this?, I had no wheel spin either time even though I let off the clutch at just under 3000rpms. Can you guys give me some pointers for next time, i need it, lol.

EDIT: I'm the 118 car with the 17s 1/4 mile.

Worst 60' EVER.

Launch upwards of 5000 and feather the clutch out.

These cars take a lot of getting used to. Depending upon what type of mods you have will determine where you should launch from. I have a short ram, exhaust, flash tune, UDP, a few other little things and i find that i lauch best at 3200 RPM's. If i were you i would go to some empty parking lot and just practice. I did that with my svtf and i learned how to launch my car perfectly.

the traction control will not be disabled below 20 mph (I think it's 20) even if you turn it off. you either need to get a tune which will completely disable traction control when you hit the switch, or pull your ABS fuse. that'll help your 60 ft and get rid of the bog you had. it was the traction control kicking in. don't launch much over 3000 rpms, feather the clutch, and you should start seeing some better times. just don't feather the clutch for too long...you don't want to roast the clutch

Hey, I did a forum search and pulled that number 46 fuse, wow, it's like a completely different car. Thanks for the tips guys.

yes you can wire that fuse up to a switch so you can turn it on/off at will without pulling out that fuse all the time.

here's the how-to > > Clicky < <

Should make this a sticky somewhere...?
 
Tips on how to run a low 15 sec 1/4 mile in a STOCK SVTF.

1) If you have the Euro package, you have to pull the fues, #46, to turn traction control off all the way.

2) Do not heat up street tires. Street tires become almost gressy after a tipical burn out. Instead, simply "clean" them off. Stay out of the water, rev the eng to about 4k and pop the clutch. Let off the throttle after 3 or 4 revolutions of the tires.

3) Stage as far back as you can for your best E.T. Once the first light turns on, slowly roll forward and stop AS SOON AS the second stageing light turns on. If your racing heads up, Stage as far foward as you can. Roll though the lights, then back up, stop as soon as the second light tunrs on.

4) Rev to about 3700rpms. Tranny in first.

5) When the 3rd yellow turns on, pop the clutch and roll the throtle down quikly.

6) At 7100rpms power shift. Leave your foot planted to the floor, stab the clutch, all the way down, and let off as fast as you can, at the same time shifting as fast as you can, into the next gear.

7) Congradulations, with practice you can now run a low 15 sec 1/4 in your stock SVTF. Imagine what you can run modded...


Notes...
-Spinning tires is bad. However, in a stock SVTF, a little bit of wheel spin will yeild a better E.T. then trying to flote or slip the clutch for the avg driver. You need to practice this. If you spin to much, lower your launch RPMs, if you bogg AT ALL raise them. Popping the clutch should get you a mid 2.1 60ft time once you get it right. With that said, with even more practice, a slipped clutch launch should get you a low 2.0 60 ft time.

-Street tires vrs Drag Radials or slicks. Do not do a smokey burn out on street tires, that'll cause you to lose traction. You only need them cleaned of debri picked up in the parking lot or stageing lanes. Do not lower PSI to much on street tires, if I run 35psi on the street, I'll run 27psi at the track. On DR's or Slicks, the more you heat'em up, the better. The lower the psi with out slowing you down on the op end, the better. To heat'emn up right, you need to engage the parking break fully, water the front tires or drive through the wet box. Rev it up to 4k and pop the clutch. Hold your RPMS at around 5500 - 6k. Once you see smoke on both sides, count to 5. One, two, three, four, five. Then disengage your parking brake, and let off the throtle 1/2 way. Let'em hook, then depress the clutch and let off the throtle. Do not "test" the tires. Properly heated DRs or slicks have their best grip ONCE after the burn out.

-Why powershift at 7100 rpms when the red line is at 7250? Have you ever powershifted befor? If you hit the rev limiter during the shift, it will alomst defeat the pourpos of powershifting. Once you get it down, shift as high as you want with out hitting the limiter.

-All this take practice. Modify everything to yeild to your driving style and net you your fastest E.T. Things like Tire pressure, launch rpms, clutch usage, shift rpms. All this take practice to get dialed in. What I have typed up is just a good starting point for the novice.

-Good luck, be safe, and have a fuggin blast!
