blipping/pulse and gliding

Post by fr4n »

how many here use pulse and glide/blip creeping method to do tight manuevers? (3-point turns/reverse parking etc)

Can you describe what it is?

Well, I might use something like a "blip" method when I'm just creeping tiny amounts. I'll be in gear, waiting to move, or going into a spot or something, and so I will just move my clutch a little so I'll start rolling then clutch back down or go to neutral for the next couple of seconds while I casually roll to where I'm going.

Is that anything like what you are talking about, fr4n?

For slow-speed maneuvers I'll usually "no-gas" blip, which I suppose is sort of an anti-blip in actuality. It's done with the clutch pedal only. I'll crawl along in 1st gear and if that has me going too quickly (such as when traversing an especially nasty speed bump), I'll clutch in and coast my speed down a little bit, then gradually bring the clutch back up to get back into in-gear crawling when it's time to accelerate. It can all be done with the clutch if you're patient.

Yeah, this is roughly what I do too. It just depends on where I am (in traffic, parking lot, etc...) how I do it.

This.

A 3-point turn doesn't cover enough ground or time to have to think about it, it's just a matter of slipping the clutch and by the time it's almost engaged I need to change direction.

In certain types of stop-and-go traffic I pulse and glide (in this context, that means engage clutch momentarily to get car going then declutch again).

Backing into a parking space I generally just go at least as fast as idle with the clutch fully engaged...bonus if I'm going far enough to hear that straight-cut reverse whine. I might brake it down below idle if I need to go just a little slower. Slower than that I might pulse and glide or I might just slip the clutch, depending on the grade and terrain. When I pulse and glide into a space I generally shut the engine off after the pulse, no need to wait until I'm stopped for that.

Hmm...what other low-speed situations are there?

Sometimes I gotta slow down to make it last. In those situations I usually thrust and slide, however.

Not thrust and hold? Sliding tends to make it worse...

Thrust and hold doesn't work for me, I gotta exit and go downtown for a snack.

what i mean is

eg when reversing or creeping and sometimes even on hill starts, you blip with the clutch partially engaged to inch up

so like a short "vroom" causing the car to inch up the tiniest bit. usually when doing small adjustments in positions eg moving maybe a foot or so quickly but carefully.

im curious to see the stats on the usage. usually see high-revving performance cars being handled in such a way. is it cos they got no low end to efficiently no gas a creep? or is it just the way typical sports car drivers use cos they feel cool? lol.

I have never done this.

Let's give them the benefit of a doubt; perhaps their multi-disc racing clutches are very touchy and difficult to move slowly using any other method. Then again, depending on who you're talking about, it might be somebody imitating that without knowing why it's done.

that could be the reason

i have a clutch like that but its manageable to creep. i cannot no gas start efficiently tho
