Ok i have a problem at the track the only time i have everbeen able to cut is a 14.3 and well that was good the first time i did.But now it is no fun anymore.I would like to hit at 13 something ant some point and time. Plz tell me what i'm doing wrong.

Launch (2000rpm)
no tire spin

hitting every shift correctly

shifting 5800 all gears

my mods
3.90 gears
random CIA
Mac 75mm throttle body
C&L 75mm Elbo
Hurst short thorw shiffter
Upper and Lower Control Arms
Nitto 555s street tires out back (285,40,18)
no spare tire or jack
Steeda UDPs
Catless Mac Pro Chamber into Flows

Launch at a higher RPM. I ran at the track for the first time the other day too, I ran a 14.1 with about 10 mph head winds. I only have Steeda UDPs, K&N CAI, O/R X into Mac Catback. With 245s. You should definitely be in the 13s easy.

I'm glad you said that b/c i dident want to try it just to be dissapointed.

By the way what RPM did you launch at.

[1BADSTANG]

make sure you heat the tires.. lauch closer to 3500. you can also shift a bit higher.. maybe you need a tune or something low 14's is really crappy for your setup.. you should be like 13.6-13.9 easy

What kind of 60ft you cutting? You've got to be bogging off the line bad.

I'll have to find my old time slips.

[WilltheThrill]

good luck man.

[HessiaN257]

When I had the 14.1, I had a 2.1 60'. Its not the greatest, but it was my first time at the track.

Let a little air out of your tires (just about every track has an air compressor to raise them back up when you leave), heat your tires up good, and launch a little higher in your RPM.

If your not scarred you may want to try powershifting your 1-2 shift at least.

I see that you live in southern OK, so I'm guessing you go to Noble to race. When was your last run? Now that the air is getting a little cooler and the humidity is dropping you can start getting some good times. This Saturday is going to be perfect weather for a little racing.

Manual transmission shifting help.

I'll pass along what I have learned over a few years.

Before 10 people say it after I post this, let me say as a warning that all these methods are for racing, not day to day driving, and yes, they are hard on your car. It's hard on the clutch, the transmission, the rear end, and the engine. And that's assuming you don't blow a shift.

Launching.

Okay. The first thing in racing is the launch. This depends greatly on your car & how much power it makes, what gears you have, what tires you have, and how sticky the track is. Atmospheric conditions also play a part in how your car runs.

The best launch is one where there is no wheel spin. Wheel spin = less forward movement. Try dropping your clutch at 2000 rpm. If the engine bogs down, you need a higher rpm launch. If you light the tires up, you need a lower rpm launch. Work your way up and down in 100 rpm increments until you find your car's sweet spot.
Sometimes, particularly in cars with lots of power, or in cars with an open differential (non-posi), or on a shitty track surface, you find that no matter where you dump the clutch, you spin the tires too much. In this case, sometimes you have to sidestep, or slip the clutch on the launch. This means slowly letting the clutch out as you roll on to the throttle to launch as hard as you can but without spinning the tires.

Shifting.

The best result for racing is power shifting. It sounds easy in principle, but it takes concentration, as a blown shift can be disastrous, especially if you are running a car with no rev limiter.

To perform a power shift, you keep your right foot on the accelerator pedal during the shift. When it's time to shift, keep the accelerator wide open. With your left foot, you stab the clutch in one quick motion, down and up, moving the shifter to the next gear as your leg is descending & disengaging the clutch. The clutch is only disengaged for a split second, just enough for you to ram it in to the next gear.

How do you know at what rpm to make the power shift? Again, this depends on the car. The reason you power shift is the quicker shift helps keep the rpm up higher where the power is. So this is also a trial & error thing, and takes you getting to know your car. If you are driving a typical Mustang GT that makes it's peak horsepower around 5700 rpm, stab the clutch right at 5700 rpm. Pay attention. If you do it right, the rpm should jump up just shy of your rev limiter, and then when the clutch re-engages, your rpm will still be right where all the horsepower is. Sometimes you're better off making the shift a little sooner in the rpm range, sometimes a little higher. If you bounce it off the rev limiter, you've made the shift too late, or at too high an rpm. You have to work at it until you get the best result for your car.


p.s. breaking shit is cool.

On the powershifting the Zipster mentioned above. I find much quicker shifts if I "Pre-load" the shifter. What I mean is I apply pressure just before the clutch stab. Pops right into place very quickly.

Yes i run at noble the track is preped good. My last run was 2weeks ago.
I'v also been told that on street tires it doest really do to much more good to really heat up the tires like John Force would with slicks. But hey i wont complain i'll try it.

I also do the power shift i'v gotten pretty good at it.

p.s i only do it when i race.

[Blackblurr_00GT]

And also thnx to everyone for the replys its really helping me learn some more.

[07stanggt]

I power shift regurlarly when Im goofing around on the street. This is not to say I do this everyday or anything but If im playing with someone at a light or the other day when I got these new tires I practiced a few launches in a parking lot of a abandoned building that I know the owners. ran it up to about 60mph becuase of space. But i powered shifted 1-2 everytime, I think i did it like 4-5 times. In the year I have had the car i have probably done it 40 50 times. Is it that hard on the car? What it is hard on the clutch or the gears? If its just the clutch I dont care. I got 4.10s now is it even harder on the car? Now you guys scared me

you should be running high 12s what your reaction time

High 12s? No. And R/T doesn't do anything for your E/T
