An aftermarket clutch and/or lightweight flywheel will cause the car to stall or shudder if no gas is applied... Only leaving one option.

thanks! just seeing if there was a more correct way.

From various articles I've read, you are always supposed to give it gas before finding the friction point. But I doubt that letting the clutch move the car a bit will damage the clutch.

Friend of mine actually had a hard time learning shifting, but I got him to read this post. great post

I live in the mountains where elevation changes drastically, is it "better" for the tranny/turbo/drivetrain to shift into 4th and stay out of boost but be higher up in RPMs or keep it in 5th, gas pedal mashed, and boosting?

Im not an authority on the matter but I do 4th with less boost. You could drive in the 3500-4k range all day with no issues.

I posed this question to a tuner, and the best answer I got (as well as from the other local shops posting) is that staying in lower RPM with higher boost is more efficient. Friction losses and all.

Well then, two different answers.. I think I'm using more gas being in 5th gear with the gas pedal pressed more than being in 4th using less gas.

Is it necessary, or more correct to do this method shown in this thread at a complete stop in first?
1) Clutch depressed, 1st gear, Rev up to 2000RPM
2) Slowly let off clutch while maintaining the 2000RPM

this whole time, I was taught (and seen other people) this method to start in first gear:
1) Clutch depressed, in 1st gear, slowly let off to where you can kind of feel the car lurk forward
2) Give it some gas and you'll be around 1500RPM with foot off the clutch

Is there a better, right, wrong, etc. way to this? Sorry if it's such a noob question, just rather learn now then damaging a clutch/transmission. Thanks!

The proper way to let off the clutch for regular driving is not to rev up the engine (even to a modest 2000rpm) and let off the clutch, but to slowly give it gas as the clutch engages so the rpm come up smoothly. A perfect start in a standard is exactly as it would be in an auto, that is, just a smooth increase in rpm from idle to shift point.

If you rev, then release the clutch pedal, you are increasing wear on the clutch. This is acceptable in some situations (like if one wants a faster launch), and is almost negligible if you're only modestly reving the engine, but why wear when you don't have to?

I think its better on the engine to have the rpm's higher that to have higher boost.

Going up a steep hill in 5th with the gas pushed further seems to me like its causing more stress on the engine from "struggling".
Whereas going up a steep hill in 4th with the rpm higher makes the load on the engine a lot easier.

Some question about my 2011 STi. When shift and down shift sometimes I feel some friction when going into gears. it will go in, just not very smooth, feels like there's a bump on the way going into gear.

And when it's smooth, it will be smooth all drive long (most of the time). When it's not smooth, I can feel the bump (down shift even up shift), it will happen to maybe not every shift but probably around 60% of the shifts.

As I stated, it will go into gear just doesn't feel smoothly kind feel like a bump in between or something blocking in the middle, and yes I always press clutch to the bottom. I think I heard some of my friends experiencing similar issue with their STis.

I'm just wondering is this a common thing? Is it because of my driving habit or shift timing?

It could be how you're shifting or your synchros could be a little worn. It would be nice if everyone could try an unsynchronized transmission, it tells a lot about ones shifting. With a unsychronized tranny you will grind if you shift too slow, too fast or you let off the throttle wrong.

You could be upshifting too slow or too fast, meaning your synchros have to do more work, hence the bump. When you downshift try rev matching.

How bad is it for the car if I over-rev when I rev-match or up-shift

I'm no expert but I would think all your damaging is the clutch. Can't imagine it's hurting synchros since your not shoving it into gear and dumping the clutch without rev matching. Flame me if I'm wrong but that's my best guess

DaBiggs is right, once you've slotted the gear in then the only wear your are going to have if you mess up is on the clutch.

Examples that might wear your syncros:
  1. Quickly skipping gears up or down (out of 5th and straight into 2nd; out of 1st and straight to 4th)
  2. Over reving when double clutching (rev too much when in neutral)
  3. When at a stop in neutral, quickly pressing in the clutch and ramming into first before the gearbox spins down.
  4. Shifting into 1st while moving without double clutching
Not all of these are going to be lethal to your trans, but if you want it to still feel brand new at 100k, then take gentle care of your syncros.

Default Muscling into first gear

Unabomber is it normal for WRX's to be a little hard to put in first gear? I get it 30% of the time at a dead stop, other times is goes in like butter. I dont down shift in first but I do in every other gear (2-4). Will double clutching or rev matching help that?
I read your post every night for 1 hour before going to bed. Thank you for all you wonderful information.

These transmissions are notoriously bad for being able to down shift into first, but I see no problem with this because it prevents damage from over-revving. You rarely need to down shift into first unless you're creeping along (<10 mph) anyways, and then it should work fine. I don't know if rev matching will help, per se, but double clutching does. The two go hand in hand if you're double clutching correctly.

I've also noticed on my car that the gears are much more notchy and temperamental when it is cold outside and the car hasn't warmed up at all.

When I down shift, I brake, depress the clutch, drop to the lower gear, rev match, and engage the lower gear in one smooth motion. It just feels right to me. Sounds like I shouldn't be doing that though.

Hitting that stiff, hard clutch twice seems inefficeint to me and tedious.

What kind of problems am I setting myself up for doing it that way? If someone can explain to me how bad I am being maybe I'll change my ways .

Double clutching was needed to synchronize the engine with the gears in older cars before synchros. Otherwise the gears would grind or wouldn't go into gear at all. With the invent of the synchro, double-clutching became unnecessary unless in specific conditions such as the aforementioned 2-1 downshift or when racing and skipping multiple gears. Even in the latter case, you most likely don't have to double-clutch; you'll just be saving your synchros from a lot of wear if you do.

With that said, if you're currently only rev-matching, you are unlikely to be creating any problems down the road. Double-clutching is just something that many find fun to master when enjoying the experience of a manual transmission.
