Title: 1/8 mile transmission gearing verses 1/4 gearing.
Post by: Rodger jeska on March 25, 2022, 01:00:33 am
Please school me here. I'm listening... I'm building a drag bug truck modestly wanting to turn 13s maybe on a good day break into the 12's in a quarter mile hopefully a little over a hundred miles an hour. Currently have a 388 rancho super Street 89 fourth. I will either be running a 24-in tire or a 27-in slick. Hopefully I will be 150 horsepower at the wheels. My current combo is only 125 but I will be adding some compression and 48 ida's... i pie cut frame head and raise torsion housing about 2 and 1/2 in... I'm IRS. Thank you

I would choose the 24 "tires
But not to be stupid towards you Why choose 3.88i R&P
If you were to build a new box for the strip R&P 4.37 / 4.13 1- 3.89 2- 2.25 3- 1.52 4- 1.13 26 "6" Wide The start is the most important thing to get off on an engine weak car PS heavy flywheel and heavy pulley so get man to 60 feet
