how to tune gear ratios in drag racing
Boost control is not typically necessary early on as this is mostly taken care of by modifying the gear ratios, but if you get to the point where even just changing the gear ratios around, having the best tires and having the right suspension tune is not stopping the wheelspin, then take the boost down in the early gears, increasing it gradually as the gears get higher, up until the point where you are just barely avoiding wheelspin. What's that worth? And all cars can be used for indy and ssr7, as long as you are racing equal cars. is powerful enough to launch you to 4th Gear in an extremely short If we divide a higher gear (like third) by the lower gear (second), we can see the change in rpm expressed as a percentage. This means that rear gear ratios are a compromise. Also different settings are used when racing 1/4 mile or 1/2 mile. You wont need to tune it until you make so much power that youre hitting the rev limiter in the final gear. Archimedes (287- 212 B.C.). Take the resulting number and add "1" to it. We haven't forgotten the autocross and track day heroes. The numerical labels on these curves show the differential ratio multiplied by the transmission ratio in every possible ratio selection. The key is to find the best balance of acceleration, top speed, and tire grip. Our classroom is Watkins Glen International, and team driver Wayne Nonnamaker is todays professor. Once the system has been installed, the book covers tuning, maintenance, and how to avoid detonation so the engine stays healthy. If you are going to advance the timing, then run the car a little bit richer. Say, for example,due to regs restrictions your peak horsepower is at 7400 and falls off fairly quickly, but the engine is fully capable of spinning to 9,000 w/o damage (though it ain't doin' much up there)? I am redlining it. Out of the box, the Drag Slash is equipped with a 22-tooth pinion gear and a 76-tooth spur gear for a total gear . All transmission gear pairs are always in mesh, but are only intermittently engaged with their shafts. Asking for a friend (of course). Those of us in Southern California have three tracks within a few hours. Cathedral, square and D-shaped port design heads are covered in terms of performance, as well as strength and reliability of . Of course, if the goal was to emphasize the highway-cruising side of this equation, we could soften the rear gear, to, say, 3.55:1. Calculators to help you out. If the car is running a smaller-displacement engine, like a 5.3-liter that we're spinning to 7,000 rpm, then it will likely be more drastically affected by a reduction in gear ratio, because small-displacement engines typically makes less torque. Make sure to upgrade the tires and drop some of the weight on the car first, so your car is capable of gripping better during take-off. In pure racing gearboxes, the gears are alternately connected to the mainshaft by stepped cogs, also known as dogs, which are designed to engage or grab the next gear very rapidly and firmly, an action too harsh for everyday driving. Coming Up in Part 3: Tuning the Sealed DifferentialIf you missed it, be sure to check out Part 1 here. Let's burrow down a little deeper into our drag car example with this ratio package. Set it around 3.2-3.7 to begin with and then tweak it after you're done setting up the rest of the gears. This process also shows how the common practice of rating engines by peak horsepower is relatively unimportant. It has eight possible gear ratio combinations. Remember when a 10-speed bicycle was considered exotic? The exceptions to this are the new of 6-, 8-, and now 10-speed automatics, but these transmissions have not found their way into the mainstream as yet, so we'll leave them out of this discussion for the moment and focus on the manuals. Can I gain compression by using older model cylinder heads? (I can provide the math for this if you are interested). You'll learn proven techniques to increase performance and reliability, and, just as important, which modifications won't give you meaningful gains. The more compression and rebound, the higher the front end lifts. Thats why i wrote that i use to make my front a little bit higher for top speed. Combining this 3.36:1 final drive with the close-ratio transmission will yield just one shift point in the first three straights, and two in the last and longest one.
