Anyone Master Downshift Rev-Matching

And blipping while going through neutral does save a modern synchro mesh tranny. Even with the clutch depressed, there is some drag in the clutch and blipping the throttle while in neutral will spin up the input shaft some, which means the synchro has to do less work.

Got it, I misunderstood what you were suggesting. It's likely that I am on the gas as the shifter goes into neutral... It's one fluid motion from one sift gate to the next. I get absolutely no resistance going into the lower gear when it's done correctly. I think that we're both recommending same method, it's just that you were more detailed in your explanation.

I thought that you were suggesting that one needed to release the clutch during the neutral blip and then re-engage it for the shift...

at what rpm are you downshifting?
for me, in normal daily drive, it's when the RPM is about 3000 so that the engine rev is kept in the 3500+ region. When I'm having fun, the downshift rpm is about 1000 higher.. which keeps the engine rpm above 4000 and ready to provide torque once my foot is off the brake and back on the throttle.
since I'm on the brake for most of my downshifts, downshift does not have to be fast, but make sure I don't $$$$ shift.

It depend on what gear I'm changing into and from where. The ratios on my 02 S are not evenly spaced. There is no "one size fits all" rpm difference with the 6 speed box. The five speed may be different.
