I don't have one and shift by ear. The car seems fairly consistent this way. I recall an interview with Herb McCandless where he said he was too busy to look at a tach back in the day!

I'm GY3's neighbor and can hear the car well over a mile away - I'm confident he has no problem hearing it red line LMAO! Rev limiter is at 6400 for a reason.... Test and tune on Kellogg Avenue.

I tried looking at the tach in my car, but just put in a shift light and called it good.
I used to race a drag bike with no tach or shift light.

Staging, shifting, crossing the stripe. My tach actually reads a little higher than my EFI does(which drives the tach). So by the time I see 7000 on the tach and it goes through the low speed computer in my head to my hand it actually shifts at 7000RPM on the nose. I used to think I was mr awesome for hitting my shift points so fast when in fact my tach was leading me so I could make them on time lol.

5 times per pass. Burnout, staging, 1-2, 2-3 and stripe. Same here. I do rotate the tach where the shift RPM pointer is basically straight up. I also put a tape mark (like a second shift RPM pointer) at the RPM where I stage.

I could not race without it.....Margins are too close these days to miss the launch rpm or a shift.....We are not allowed to use air to shift in our class.

I'm just a "baby" when it comes to the 1/4 mile stuff...seriously, probably at most 10-15 passes TOTAL...so the shift-light is a life-saver...seriously, when you do track as rarey as I do it just gets too busy when you're finally there, a shift-light lets me focus on feeling the car move off the starting line, engine revving and when the light goes off I bump the ratches shifter into the next gear.
Now from a street point of view I use the tach all the time..somehow it seems to be 2nd nature there...probably b/c we all spend so much time on the road as is, maybe it helps that my daily driver is a 5-spd car anyways and I always catch the tach there.
