I Need Help Racing
I got a 01 Cobra, shes quick but i cant seem to get my shifting down to keep up with my fellow highway racers. I usually shift around 4000 rpm , but im starting to wonder if i should let it run higher but for some reason im afraid to cuz i dont want to hurt her. Anyone know the best way to shift between gears to keep up with those pussy ass vets and chargers?

Yeah, you should be shifting closer to 6k... It's a 4valve engine and it needs to breath to really make it's power. If you're worried about missing gears try this. It sounds cookie but does help some. Sit in your car with the engine off just like you were going to be racing. Practice changing gears from 1st through 5th. Use the clutch and go fast just like you were racing someone. It helps with muscle memory and timing between your foot and hand on the shifter, plus with the engine not running you don't have to worry if you miss one or two gears!

Welcome Dupes! Its a COBRA......32 valve......320hp@6000rpm.....redline@6800rpm and last but not least fuel shut-off at 7000rpm. Music to my ears. Basically dont be afraid of the high revs. Your car will actually thank you for it. Happy racing.

But you still won't be keeping up with vettes, but chargers shouldn't be a problem.

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.

But shift at like 6500. Go out right now. Get on it and shift like you have been, then do it again and shift at 6500-6800 and feel the difference.

Yeah I got tired of typing out how to launch and power shift all the time, so I just copied the last thing I wrote up about it and saved it. lol
