Stock Tranny Guys-What gear do you burnout in?
 
I always burnout in 1st gear, but have been thinking about slipping it in to 2nd while in the box. What do you do?

Straight up 4th gear , 470/480 ish HP

tom94RX-7 01-20-13 10:58 AM

I've always done it in 2nd gear.

sk8world 01-20-13 10:59 AM

2nd gear for me. I start in 2nd also.

Yea, 100% 2nd, I spin the tires in first rolling through the water, put it in 2nd, Line lock, dump it around 5k, hold it @ 7k, till you start to feel the "marbles" under the tires, relase the line lock, take it to 9k, and roll it out

the higher gear you wont have to burn out as long and you can get more heat in them quicker

3rd with 13bpp all motor and a 9in Ford with 26/15/10in tires......

You mean for the actual race? No.... Just burn box.

While exploring my lack of knowledge of a proper burnout, I stumbled on this from Mickey Thompson. I thought it was some good info to share, since we are on the topic.

This also brings up the question: Is anyone using a digital infared thermometer to check track temps and post-burnout tire temps?

Mickey Thompson Performance Tires & Wheels

BURNOUTS- FOR MOST APPLICATIONS
The length of your burnout will be dictated primarily by the ambient and track conditions. The hotter the temperatures, the shorter the burnout. When the temps get cool, a longer burnout will be necessary. Ideally you want the tire temp to be within 15 degrees of the track temperature on the launch. When the track temps exceed 120 degrees, it is always best to keep your tire temps on the lower side. Here are some additional tips for maximizing the performance of your M/T racing tires.

1. First pass of the day will be your longest. After that follow the guidelines of #2 and #3 stated below.
2. Automatic transmissions and Bias tires with Softer compounds: First pass or two, fairly hard burnout relative to ambient conditions. After that a light burnout should be sufficient.
3. Standard transmission and Radial tires: Typically shorter burnouts are better. A light burnout, enough to haze the tires, then stage immediately.
4. No dry hops. This does nothing to improve traction, and in some cases can have a negative effect.

Back when I had a FC, depending on track conditions but usually day time would do 2nd gear and night I would do 3rd gear. My line lock is installed on the rear breaks so as soon as the clutch is dumped I left foot break. Then as the tires feel like they are getting hot, I ease up on the break peddle and role forward.

jamespond24 01-22-13 04:35 PM

2nd or 3rd gear

RX200013B 01-23-13 11:17 AM
