1st gear lockout question?

fwiw, 1st gear has triple cone synchros

fwiw = for what it's worth
Multiple cone synchronizers reduce shift effort, despite having triple cone synchros the short throw shifter forces you to use some effort to get it in gear, it takes some constant force on the lever for it to drop in, the highest gears usually only have one cone

you probably overslowed then, if you set up the braking zone to go wide on the entry there was room on the exit to carry the speed through the turn in 2nd

I was pretty sure it was faster when I was doing it, and I did carry enough speed with the downshift to push out where you're talking about, and I was set up for the wide entry. But who knows.

trust me, I left a lot of time out on the course, including that corner, by no means am I implying that I was at the top of my game
if it makes you feel better, my codriver never downshifted there :p if anything it was probably even-steven to do it either way, making the shift only allows the potential for screwing up

I've pretty much decided next year will be spent doing more schools and fewer tours.

Our car has seen 1st gear at an event once, when we first got it, now we know we dont need to use it. I had the times to win the pro, Red lights, without 1st gear. Stayed in 2nd both natl courses and trust me the .2xx I was behind the first day was the big drift in the showcase not due to staying in 2nd gear.
I would side with teamrx8 on this one, if you were going to 1st on the North course you were slowing to much. I had no bog at all in that turn holding 2nd.
I guess to many years driving a vette, I just dont like to shift. Same thing at the UT pro, ran with the top times and coned away faster ones. Everyone else used 3rd, I just banged the limiter in 2nd. Every shift is lost time and the chance to make a mistake. imho

Bog is a relative term with this car. Anything under 6000 RPM or so feels like a bog to me.

Also what is the point of using 1st gear if you have to roll on the power.... While you are waiting for traction in 1st I am floored in 2nd.
Hey, you guys keep shifting. :D

Just to pipe in here, I ALWAYS double clutch ALL my downshifts. Why? Well, it virtually eliminates the wear on the synchros and if I ALWAYS do it, then I don't screw it up when I need it most! ie, autocross 2->1 downshift. When I'm braking, I ALWAYS HEEL-AND-TOE-DOUBLE-CLUTCH-DOWNSHIFT. Mostly for the same reasons. If you get good at it, you won't be able to measure the extra time that it takes to put the clutch in and out that one extra time. By double-clutching, you'll find how EFFORTLESSLY the shifter will drop into your lower gear, assuming that you've properly rev-matched. I know if I were racing that I wouldn't double-clutch, but considering that I'm tracking my own car and I don't have a personal mechanic, I'll keep double-clutching and not worry about that extra .00x second that it takes.
Also, I can up and down-shift WITHOUT the clutch. However, it takes a lot of concentration and isn't as quick as a result. I do it to show off every once in a while, but that's about it. :D

Well if you were so fast there where did you leave the rest of your time. :D
Sorry had to do it.

Know you were joking, but... a couple tenths due to indecision at the end of the slalom. Had it in my head that I wanted to do the inside-outside line on my last run, but carried a bit too much speed at the end of the slalom to accomplish that. Didn't carry enough speed to do the outside-inside line quickly .
Plus never getting the feature sweeper quite right - but I was still flat out so maybe it didn't matter too much.
Oh, the cone didn't help either
Let's not even discuss friday...
