ET Differences Between Varying Powerglide Low Gear Ratios?

JP Schuster · 11-06-2017, 08:53 AM

I was curious to know how much ET could be gained/lost by changing the low gear ratio of a Powerglide? I know the ratios typically range from 1.76-2.18, but is there a sweet spot for how much harder the car leaves vs. subsequently how long the car is in high gear? Or do the 60' gains outweigh the longer amount of time in high gear?

Background: I currently have a 1.94 low gear PG and I am looking to speed up my 60's. Would a 2.08 / 2.18 low gear be worth the investment?

Thanks,

JP
