Your car will use more fuel when your in neutral. If you're car is doing 50mph and you're clutch is engaged, it will use its own power to keep itself going. If you disengage the clutch (even when driving slowly), it starts using alot more fuel.

1) depress clutch
2) shift from 5th to 4th
3) blib gas and let gas off very slowly
4) let go of clutch

I skip the neutral part...
You are in neutral until you let go of the clutch

Hi guys,

when pushing it, how do you upshift? Is it OK to:

1) Full throttle
2) Jab clutch, change gears
3) Apply full throttle?

Or do you have to give it gas as you're releasing the clutch? I sometimes have problems when I shift at 6.5krpm, I give some gas, and I hear the engine rev up, and then the clutch engages... so can I give less gas?

Also, does the CDV have any effect on this high-rev high-speed upshifting? The effect seems greatly increased for me at high speeds, dunno if I am relating it to the right thing or not.

Thanks.

I feel like my shifting is still very slow, especially my 1/2

How far do you guys clutch in when shifting: just barely past the point where it disengages, or pretty far in? And do you do it differently when driving slow vs racing?

Whether driving slowly or racing once the cluch is disengaged there is no advantage to pushing it in any farther.

so you just barely push it in, like 2 in when you shift?

Push in in until it disengages and then very slightly more (like 1/8") if you want to be sure you are not slipping it. Once you get the feel of it it is second nature.

If you have had a chance to see how the clutch is put together, you will be VERY surprised in the amount of gap between "engaged" and fully "disengaged."

It is on the order of MILLIMETERS.

thanks guys!

Also,
1. what is the rationale behind launching from 2nd gear vs 1st?

2. Is it faster to launch by taking 1st gear up to 3k and then 2nd to redline, or just redline shift redline?

Hmm. what's up with videos of people timing 0-60 times from 2nd gear?

So for fastest time, I wanted to make sure I didn't overlook anything in assuming the fastest way was 1st to redline, 2nd to redline, etc.

Ok so I am quite concerned with my clutch. It was just replaced, and I continue to smell it burning after I park. What causes this? I will explain how i drive the car and maybe someone can tell me what I am doing wrong.

1. I start the car with the clutch to the floor. I begin to give the car gas and slowly release the clutch. Seems that if i release the clutch quickly i either stall or the car hiccups.

2. If I am going from lets say 75 miles an hour to 30 miles an hour. I will be in sixth gear i will slow down till about 40 and then engage the clutch and go into 3rd gear. Is this wrong?

3.When turning i will engage the clutch and release when the turn is over and will be in 2nd gear.

4. If i am going 80 and i see traffic infront of me i simply engage the clutch and coast to the traffic and then put into 1st or 2nd gear when at the appropriate speed. Am i suppose to go from 6th-5th-4th-3rd-2nd.???

im new to driving stick. when reversing i kind of juggle gas and clutch, once moving it disengage clutch, and coast reverse, if i need to move more i just barely engage clutch and gas. basically i never fully engage clutch in reverse, nor do i ride the clutch except to start moving.

Many cars that have performance modifications start in 2nd.

Probably not a good idea to start in 2nd if you have a MT. Easy way to glaze / burn your clutch.

QUick question guys....

At the track, when im coming from a straight going 180-200+, how do I tackle a turn thats pretty much 90 degrees?

I mean in terms of shifting, since theres quite a bit of hard braking, should I be going 5-4-3-2 or just slow down, double clutch and pop into 2nd? I find that when i go through all the gears, I end up having to slow down well before i really need to.

Any opinions?
