Turbo Action 23254 Spring/weight question

CrateCamaro · 06-23-2016, 11:50 PM

Im assuming this thing shifts off output shaft rpm so previously i had a spring and weight combination to shift at 6500 with a 2.52 low gear. If i was to change to a 2.75 low gear, the driveshaft speed would be lower at 6500rpm and make the trans shift the 1-2 at a higher rpm correct? Check my math for me and see if im even thinking correctly:

6500rpm ÷ 2.52 = 2579 output shaft speed

2579rpm output shaft speed × 2.75 = approx 7100rpm 1-2 shift

Please tell me if this sounds correct.
