Coaching Tips -  Where is the Limit?


brake timingRacing requires 100% of your focus for a given time period. During that time the bad waitress last night doesn't matter, nor does something at work last week. What does matter is that you pilot your car as close to the limit of doom and danger as possible and bring it back safely.


Sometimes that limit is your mental ability to process the enormous amount of information occurring in the car at speed. Other times it is the car's limit to perform at a level necessary for you to beat the competition. However, new coaching technology can address all these and move you to a new limit.


Imagine how it would help, if 30 to 45 minutes after a test/run/qualifying, your cell phone rings and you get this report: "Not sure you noticed, but you did turn 8950 on one lap that run and the water temp is steadily climbing every lap, so keep a close eye on the engine. Next, your braking in Turn 1 is greatly improved and there may be a tiny bit left, but not critical, so let's work on another corner. Turn 6 braking is too soon. Do you have a deeper mark or can you shift your reference point to brake release rather than brake application? Also, it looks like the rears are far from locking up anywhere on the track so go ahead and dial some front brake out of it. Turn 4 still has moderate understeer and 6 & 8 heavy understeer so on the car let's change......."


This isn't science fiction. It is exactly what one racer experienced last weekend where he qualified 2nd fastest on his first time at that track. This is now possible by using Offsite-Data Services and the data acquisition system in your car. You can have this advantage, too,  if you have an AiM, CDS, MoTeC, or Pi data system in your car and you can reach the Internet at your track via "air-card" in your laptop or cell phone interface.

Shop Tips -  Spreadsheet saves shop time


lathe chartIf you have a lathe in your shop and you are not a full time professional machinist, you may be wearing out your tooling too fast or not taking full advantage of your machine.


You are likely aware that there are recommended cutting speeds for  different materials, but often, access to that info isn't easy.  So, here's a tip to remedy that situation.


Granted, different tooling and cooling have an impact on these cutting speeds, but this tip will get you close.


Use your computer to create a spreadsheet with columns for each specific speed your machine will turn.  Make the row headings with 250 thousanths increments for the diameter of your work.  Next, use the equation in the section below to fill in the cells of the spreadsheet.


On the bottom of your sheet add the following material type info: 

               Heavy cut   Finish cut

Mild steel        90          100

Cast Iron        50            70

Brass            150          300

Aluminum       200          300


Print your spreadsheet and tack it on the wall by your lathe.  Check the sheet for the material type you plan to turn and the recommended cutting speed. Now, measure your work and find that row on the sheet. Lastly, identify the column that produces the recommended cutting speed and set your machine accordingly.

Equation of the Month - Surface feet per minute 


For a change, the first time in over 3 years the equation of the month will not be related to your racecar, but rather, a shop equation to go with this edition's Shop Tip.


SFM = D*Pi*RPM/12


SFM is the surface feet per minute, D is diameter of your work in inches, Pi is 3.1416
