Converter and gears question

[James Vincent]

How much et are you guys shaving off with a converter and gears on your supercharged set ups? Currently running a vmp stage 2 setup with stock converter and 3.15s. Car runs 11.0s at 126 mph with a 1.73 60 foot on a radial. Is a 10.50 pass possible with 3.31s and a circle d converter? Car also has stock headers, cats and intake.

What size tire are you running? 3.15s will keep you in your power band longer with boost

 

[James Vincent]

27 inch tall tire. Brings the gears to about 3.18

keep what you have out back and do a converter, you might need a couple more mph on the top to run your desired number though.

Which pulley do you have?

A tune with some more spark in the low rpms will improve the 60' a bunch. If you have an 82mm on the car, 1.5's should be no problem on 93.
