When do you shift
 

Just curious, when do you go on the stop, when do you shift and what rpm do you cruise at. Just wondering how many different set ups people use

Re: When do you shift
 

My car is slow, so to get it rolling I go on the stop at 0.500. Cruise at 4200 (RPM set in the pits. I don't know what RPM it actually cruises at on the track). Off the stop somewhere around 1.600 and shift by hand at 7000 rpm.

Re: When do you shift
 

I go on TS at .08, cruise at 4200 and shift at .40. 10.90@138

Re: When do you shift
 

I go on the stop at 0.001 and coast at 4150, shift at 0.30, 9.90@183

@ 2850 Lbs on the stop at .000, shift .75, 4200 stop rpm, between 3.75 & 4.25 sec. in the stop. 10.90@152

I’m not saying, But its somewhere between zero and 10.90. 😆

Right before the holes appear in the oil pan !

Re: When do you shift
 

Do you shift that far out to make the 60’ more consistent?

Re: When do you shift
 

The transitions were smooth & that's what I looked for. But Keith has the inside stuff, he just doesn't share as well as play well with others on the 1320.

Re: When do you shift
 

When I had my big motor in the car I could go on at .001 and shift at .20 and it was consistent. When I put the 467 back in, it seems to struggle sometimes shifting that early and the 60s aren’t consistent. The farther out I move the shift with this motor, the more consistent it seems to get. I think it knocks the breath out of this smaller motor when the air is bad. That’s why I was curious

Re: When do you shift
 

I messed around with shift points a bit last year and didn't notice any difference in consistency, but I did pick up some MPH shortening the shift from .65 to .30 (first timer is at .15). This was on my S/G TBird which is pretty light at 2465 w/driver and a 600" motor.

Re: When do you shift
 

Yep 2820 lbs is different is believe.

Re: When do you shift
 

I think weight and HP makes a big difference in how early you can get away with shifting

Re: When do you shift
 

I agree, but will also include hp and weight will determine how early you can turn the stop on.
