Yeah, if it's out of range you're boned. The cool thing about a glide/strip setup is that you can run a really high stall to get that sucker spun up and if you're running big slicks they grow as you go down the track which makes your gearing taller. You wouldn't think that 2 gears will get you from 0-160. But it works.
Guys,
Here is just one of my videos from Sebring.
Feel free to watch the whole thing, or, just skip to 2min in.
The back straight at Sebring is what I'm talking about.
A buddy says he can stretch 3rd and 4th, and not hit fifth, I use 5th.... He picks up probably another 5 mph too
Seeing it will give you a much better visual
But yes, the upshift, no power in 5th, downshift, I am probably losing a full second, so it does make a difference. But again, I need to drive my car home at the end of the day.. so,
And also, its not just the back straight, there are 2 other places on track where I do the same thing, so, maybe 3 seconds.. thats huge
Lito,
Yes, I want to stay in 4th on the long Sebring straights, I'm hitting 5th half way down.
Next time I will shift 3rd and 4th about 6200 ish,
Yes, 3650. Had the same issue in my old track car, 5th gear over drive is a killer.
Thanks.
Watched your video, me thinks you can easily go all the way around without ever use 5th again, you have cams in that car, let it breath, those shift points were good if you were on stock cams but not HRs. Stay on it.
Here is a video I made a couple of years ago at Millers on a licensing weekend, there are couple of spots where I almost touch the limiter in 3rd as there made no sense on shifting, it is a FR500S which is a stock engine 3V car.
Sunday quals, fast lap starts at around 8min mark.

You are shifting WAY early and WAY to often. With cams you need to let her eat! Even with your stock rev limiter you prob never need 5th?? If not, bump it up a touch and cut some serious time off your lap!
Na, I was doing it because I'm still learning about S197's
I tracked my 00GT for over 7 years, so, this car was new to me.
All I knew was that the actual "Red Line" on the tach is at 6k, so, I thought that was the redline. I thought I was being just a little conservative by shifting at 58-5900.
Thats the whole reason for the thread... so, definitely going to step it up
Probably set my shift light to 6k, that leaves a little breathing room,
Whiskey,
Speaking of keeping the temps down, when I ran this summer, removing the front grill made a huge difference, just fyi,

I don't open track my car, wont any time soon either. Autocross is pretty mild on drivetrain heat compared to open tracking. That said, I'm shocked you saw a coolant temp drop by opening up the front grill... so much air under the hood and going around the radiator would seem to defeat the purpose of opening up the hood... that is unless you've done something to force the air through the radiator and then pull it out of the engine bay.

I would run it till it stops pulling, when you feel the tip over hit the next gear. Unless like me your limiter is too low and the car is still pulling like a train when it hits the limiter. I have seen cars like your making usable power up to 6400 RPM and a little beyond. I would say set the light for 6200 RPM, then cover your tach with tape. Shift by feel and sound over what the tach says.

Still like to know what your axle gearing and rear tire size are. Gearing and/or tires that are too short for the course can force an upshift that slightly taller overall gearing would avoid.
Your road speed at the 3-4 shift is over 10 mph less than what mine is at a 5900 rpm upshift annunciator, and I'm tripping the upshift light in 4th on the ~2100' long main straight at NJMP/Thunderbolt a little before having to brake for T1 (speeds somewhere in the high 120's down to ~70). At 120+ in 4th, the mph's add pretty slowly, but it hardly seems worth using 5th with its somewhat clunky downshift over only the last 3 or 4 mph when 4th is still good enough. That may change in the future, but 5th and maybe a 1 mph bump in top speed (observed) doesn't make any sense for me yet.
On rev-matching 4th to 3rd, I'm lighting the 5900 lights more often than not. Don't know how much higher it's going.
Supposedly, Sebring's back straight is 2600' or so, just saying. I imagine that nighttime takes some of your speed away.
I agree with the other comments about shifting a little low, but I fully understand the matter of needing to be able to drive it home (and use it the rest of the following week). Sometimes shifting a little early is even the better way to go, if the alternatives are having to shift in a fast corner or running the revs way past where you would otherwise.
I use Dashware as I got it a few years ago but probably there are better/updated tools out there, the thing with dashware is that is fully configurable.
