Wondering what RPM to shift at when drag racing 1. Take it to the dyno and get a power chart that way you can mathetically calculate the optimum shift points for each... 2. Run it down the track 30 times and figure it out where it likes to be shifted for the best times. You components will...
Best RPM to shift at when racing? | BimmerFest BMW Forum

EDIT: in other words, it is better to go to 6500rpm and shift because your rpms drop to say 4800rpm in the next gear. That is faster than shifting at 6000rpm and having your rpms drop off to 4300rpm and having to build from there vs 4800. Harder to go from 4300rpm to 6000rpm than 4800rpm to 6500rpm.
Optimal shifting RPM? | GTPlanet

The 1-2 shift at 7200 RPM pulls the engine down to 4400 RPM, where 2nd will deliver 265 ft-lb of torque. Not only did you win by maintaining the high torque of 1st all the way to 7200 RPM, you are now better off in second …

A high-rpm sportsman engine really needs a high-stall torque converter to realize its potential. With an automatic transmission, the engine speed should ideally drop 1,000 to 1,300 rpm after a gear change. For example, if the converter stalls at 6,700 rpm, the engine should be shifted at around 8,000 rpm.
Sifting on time instead of RPM - Racingjunk Forums
https://www.racingjunk.com/forums/showthread.php?t=24653
Right now the transmission shifting is being controlled on RPM (7400) by my Biondo Mega 450. I would like to figure what time interval I should enter into the box, for a starting point, to allow the shift into second gear when the box is controlling the shift by time. I am not using the throttle stop at this time. use the playback tach and find ...
shift points, vs finish line r.p.m - Don Terrill’s Speed-Talk
https://www.speed-talk.com/forum/viewtopic.php?t=19260
If you are shifting at the rpm for best ET (must be tested to know) and geared for best ET, the finish line rpm will normally be well past the shift rpm. I would say on a 2 spd PG the shift light should be on again near the 1000' (or before) to ET best in 1320. With a 5 speed it probably wouldn't be as early, but still well before the finish line.
drag racing, torque curve and rpm | Chevy Nova Forum
https://www.stevesnovasite.com/threads/drag-racing-torque-curve-and-rpm.678426/
Shift rpm should fall back about 1,000 rpm. Shift rpm should be above peak HP, ( alot of debate on how far past) I have used 200-500 rpm past peak hp . Gear the car to go through finish line close to or above shift rpm. Cam manufacturer specs are only a guide, way too many variables to use as optimum shift point and stall speed choice. Aml396 Save
RPM Fall Back After Shift - Don Terrill’s Speed-Talk
https://www.speed-talk.com/forum/viewtopic.php?t=10378
E.g., if peak power is 600HP @ 7,000 RPM and you shift at 7,600 where the power has dropped to 560, the RPM after the shift should be to whatever RPM gives you 560 HP. If after the shift you are at 570 HP, you need to drop your shift point a bit. If after the shift, you are at 540, you need to raise it. This gives the maximum "area under the curve" for best overall …
Determining shift point - DragStuff
https://www.dragstuff.com/forum/viewtopic.php?t=3276
Typically if you can feel it lay over before the shift, it started to do it much earlier than that, so start testing lower RPM shift points. Maybe it doesn't actually stall that 6000 RPM. If that was the case it's only gaining a few hundred RPM before the shift. Do you have anything that records the engine rpm down track?
