As the lining on the clutch disc wears over time, the clutch starts to slip and later, forward momentum can be affected. To get an insider's perspective, we convened a panel of seasoned heads-up veterans featuring NMCA Pro Street Champion and former NHRA Pro Stock racer Pat Musi, NMCA Drag Radial Eliminator racer Troy Pirez, and NMCA Real Street racer Patrick Topolinski from The School of Automotive Machinists, to find out how reading timeslips helps them stay at the top of their game. If we can post decent numbers at our track, rest assured you'll be flying anywhere else. I assume that the track where you are racing is using a .500 tree, and with .500 being a perfect reaction time.

I looked at about 10,000 runs, and here is the density curve of how many times a certain reaction time happened: It starts at about -.500 because LB3 (left before 3rd light) data is rarely given, and goes well into the 2+ second range for some reaction times. Reaction Time. It is important to notice that no sliding is occurring between the tyre and the track, which makes the term “slip angle” somewhat of a misnomer. CC.

Our theory is to run what we brung. Drag Racing reaction times explained by Tony Pedregon, a 2-time NHRA Mello Yello Drag Racing Series Funny Car Champion from Torrance, California. Absolute air pressure (14.7 psi) is a constant indicating the weight of air at sea level.

Make it a point to write down all the details immediately after a run.

Well now you can with the Time Slip Simulator, a revolutionary new drag racing tool that lets you replay your runs in 3D just from the data on your time slip! When read properly, the timeslip can tell you exactly what the car is doing at any given moment of a pass.Troy Pirez: Numbers are everything. Your E.T. When you (hopefully) blaze down the track, you’ll turn off shortly after crossing the light sensors that display your time. Then it’s on to your 1/8th mile, which is where some tracks stop, but this is where you see a lot of your torque. We recommend the Time Slip Program to be operated on the Announcer P.C.
