Calculators

Tire Size Calc. -(RockCrawler.com)

Crawl Ratio - (4lo.com)

Tire Size Change Calc. - (4lo.com)

Poor Mans Dyno - (4lo.com)

Convert Liters to Cubic Inch - (4lo.com)

20 degree RTI calc. - (4lo.com)

If you need to convert an RTI score to see what your score would be on another degree ramp you can use this exquation. divide sin(degree° of original ramp) by sin(degree° of desired ramp) to get your converted RTI score.

Here is the equation for calculating your RTI score:

(distance up ramp)
-------------------------- X 1000 = RTI score
(wheelbase of vehicle)

For tire size calculators, I like miata.net's one. It gives you a graphical indication of the size difference and how much it will throw the speedo off.

Tube Coping calculator

Post by Vec » Sat Feb 21, 2009 6:13 pm

tube coping calculator.... sweet !

found this gizmo, it will come in handy for building a cage

you can print out the result and make life easy

In case it's not entirely obvious, the point of this thing is to create a cutting pattern for a tube or a pipe to accurately fit it at an angle to another tube or pipe so that you can weld it. This is a whole lot easier than eyeballing the cut and scribing it by hand, and if you do it right, both the grinding and welding are pretty easy. This process is also frequently called "tube notching" or "pipe notching"
