Default xxx-t gtb 3.5 Gearing

I was wondering if anyone could direct me toward the correct gearing for a 3.5 gtb in a xxx-t. I want to do some speed runs but also want to be able to race.

For anything but speed runs this motor is too fast for a 2wd truck. Get a 6.5 for racing you will be much happier on the track!

I ran 14/86 in my XXX-T CR. I had my throttle EPA set to 70% and it was still too much - but driveable. Just make sure your diff and slipper are set right - that's a ton of power.

it means with the amount of rpm from the 3.5 motor you will probably fry the slipperclutch

hey guys, how come novak never released a gearing chart for the 13.5?

I have it at 87/24 in my T4. Its fast, but I know it can probably be faster if I change the gearing a little.

With that motor, the car will either take off like a 747 or it witll flip back and you'll either bust up teh body, brake the shock towers, bend the shock shafts.
