How much do you 'blip'?
Do you gauge it by rpms or the amount of gas you give?
Does it depend on how fast you're going? Your RPMs?

When do you release the clutch after you blip? As the RPMs are going up, down? or at its pinnacle?

 

sound, feel, instinct, being smooth.. it all comes with practice and no bad habits. you blip as much as you need depending on different gear choice. you should know what the max mph for each gear is capable of and what you're going to need to be downshifting for like braking for a turn, or accelerating on the freeway, etc.

go to this website : http://www.turnzero.com/technical_resource...gear_calculator and select the s2k from the dropdown selection & then enter your tire/rim size and you can see how much the rpms differ.

if you look at 45 mph in 3rd gear, it's about 4500RPM and 2nd gear 6000rpm.. if you wanted to downshift to 2nd quickly to accelerate, you would put the clutch in and rev it to 6000 and release the clutch as the rpms are just about to hit that rpm on the way up. then you can just keep it floored once the clutch is released so your foot never gets off the gas. you dont have to know every exact detail, but just the feel that downshifting each gear is gonna give an approximate 1500-2500rpm jump so you just blip for that area. its about being smooth and not upsetting the suspension. practice with 4th to 3rd gear shifts and then move down, you'll get a feel for it. after riding sportbikes it became really easy to transition into driving the S.. i am so glad i bought this car

 

I rev match, or blip almost anytime i'm slowing down - or are anticipating to slow down. Try to study the tach vs. speed in various gears, and you'll get the hang of it. After a while, you'll be able to feel the necessary RPM's in which to rev match before downshifting. I must say that the S2000 is one of the easier cars to rev match in. My G35 is easy, but certainly not as direct or responsive as the S. Good luck.

 

Practice.!!

 

And when you're REALLY ready for fun, practice double clutching from any gear to 2nd at 45mph. Clutch in, select neutral, clutch out. Blip the throttle up to ~6k, clutch in, grab 2nd, and GO.

It may sound complicated if you haven't done it before, but all the above can be done in a fraction of a second.

Disclaimer: The above activies are considered reckless, childish, and immature, but can be a lot of fun. mileage may vary. expectant mothers should not ride this ride.

 

is there any long-term effects of not rev matching?

 

^^^ Engine braking has been a heavily discussed topic in terms of it's wear and tear effects (if any).

 

"How much do you 'blip'?"
It depends if I am upshifting or downshifting, what speed i'm at, and what gear i'm putting it into.

"Do you gauge it by rpms or the amount of gas you give?"
I'm not really sure what the difference is here , I guess both since the RPMs rise when you blip the throttle. The idea behind blipping the throttle or giving the car gas in between shifts or when downshifting is to have the engine at the same RPM that the car would be at if you were to just switch gears, leave the throttle alone, and release the clutch (ie. if you were to downshift from 4th to 3rd and you knew that the RPMs would roughly go from 2500 to 3000 then you will blip the throttle before releasing the clutch entirely out so that the RPMs would be at or very close to 3000 so that when you release the clutch it is smooth. This all comes with practice, after a while you won't even have to think about it or study the RPMs, you can just hear the engine, see what gear you are in, and feel it in the clutch and judge how much gas to give it. If you are downshifting very aggressively then you will know that you have to raise it 1500rpm or so, but if you are driving normal then it may only be a few hundred rpm.

Does it depend on how fast you're going? Your RPMs?
Yes, and what gear you are in and going to.

When do you release the clutch after you blip? As the RPMs are going up, down? or at its pinnacle?
You release the clutch when the RPMs are where you want them. If you think the car should be at 3,000rpm then you wouldn't release it at 2500 while it was climbing to 3,000, you would release it at 3,000 or start to let it out close to 3,000 (its hard to explain in text because when I drive I just feel it, and after some time you will understand it). Just practice and it will come to you.

 

Well, for short-term effects it will feel like an idiot is driving the car. It will be very jerky and not smooth at all if you downshift and don't blip the throttle (you know that feeling where you body feels like its going to go through the windshield). For long-term effects I would say increased clutch wear and possibly shock to the drivetrain if you drive aggressively and can't rev-match your car.

 

So can I run the steps through you guys and let me know if I am correct?

For downshifting for a turn, say 4th to 2nd.
I'm off the gas > clutch in > shift from 4th to 2nd > rev to the correct RPM and hold gas there> release the clutch?

Is that how it's done? Couple of questions. When you rev to the correct RPM, you do gas quickly or like really quickly? When you release the clutch after you've reached the correct RPM, do you still have to hold it there for that split second for a smooth transition, or do you just let it go?
