You wont need to tune it until you make so much power that youre hitting the rev limiter in the final gear. How to pick the right gear ratio for your needs Although this is a limited exercise, we can still study the compromises forever without reaching the optimum solution, which is why pros want a quick-change trans with many options in each gear. For Mustangs built for drag racing, there are a lot of factors to consider. If the rear is too high, though, then the front end could pop off the ground during lunch, causing you to do a wheelie or flip over. These curves also illustrate why its so important to have a relatively flat engine torque curve over as broad an rpm range as possible. How To Choose the Right Gear Ratio for Your Muscle Car or Drag Racer All transmission gear pairs are always in mesh, but are only intermittently engaged with their shafts. Sometimes the last two are at odds with each other. The numerical labels on these curves show the differential ratio multiplied by the transmission ratio in every possible ratio selection. Suspension tuning is more of an art than a science, and you will have to retune it as you increase the power of your car. #13. The manuals gearing chart makes it easy to see which ratios are safe to use, and which you should reserve for racing and speed runs. What is at least as important as the final-drive may be the gear splits between first and high gear. At lower vehicle speeds you can see the tractive forces are very high. Here is a down-and-dirty way of picking the best gearing for a particular car from three choices: 3.07:1 final drive with a wide-ratio transmission, a 3.07:1 final drive with a close-ratio transmission, and a 3.36:1 final drive with a close-ratio transmission. We simulated that tire-change situation of a 26-inch versus a 28-inch tall tire using a taller 3.55:1 (versus a 4.10:1 gear) ratio, and the car lost barely 0.07-second running 10.30s at 130 mph, but cleared the lights with the taller tire at 5,800 rpm instead of 6,700. With traction, the 10L80 would have been even quicker. The final part of the book focuses on modifying specific engines: American V8s, Porsche 911, Volkswagen Air-cooled and Water-cooled, Cosworth BDA, Formula Ford 1600, Datsun 4- and 6-cylinder, and Mazda rotary engines. Doorslammers added that over-revving a gear could result in adding a tenth of a second to the user's time. It may be burning oil, it may be leaking, the compression may be so low that it only starts on cold days, or maybe it just isn't very efficient anymore. But still the majority of passing at SSR7 occurs at speeds of 170+ which is the top end speeds at Indy. Like we said, the realities of the situation may limit which of these choices you can make. Access Drag Performance Calculator. Suitable for students, hobbyists, and independent developers, this no-nonsense book helps fine tune an understanding of solid engine design and implementation for creating games that sell. The 17 / 86 gears require 5.06 pinion revolutions for each spur gear revolution. the book covers tuning, maintenance, and how to avoid detonation so the engine stays healthy. Think about that. Start off by tapping the first gear down the most, and tapping the next gears down slightly less (such as fifteen taps for first, 10 for second, 9 for third, etc). If i take my best indy car, alter ONLY the transmission, it will most defiantly lose at SSR7. Maybe second gear is too low and you have to shift right away into third, or perhaps that gear is too high and you dont have enough torque. These, and other important engine related questions, are explored and discussed in this book. For example, a 4.40:1 final drive is actually lower than a 3.70:1 gear. First Edition Hb (1998): 0-521-59330-1 First Edition Pb (1998): 0-521-59674-2. People even jump on ghost sometimes . Or not.

Passenger car transmissions make this connection with friction surfaces which contact first, to match rotation speeds more smoothly.

For good drag launches, you often want the lowest possible first gear ratio and carefully spaced steps from there. The book covers virtually all configurations of commercially-produced engines, and features the latest engine technology - - including up-to-date coverage of electronic engine management and exhaust emission control. You can change tire diameter, but this usually has a minor effect on gear ratio and a major effect on handling and ride height. Again, the overall first-gear ratio with the TH400 and 4.10:1 rear gear would be 10.168:1. Cookie Notice Assuming a 3-inch diameter, a 54-inch long driveshaft will hit its critical speed at 136 mph using a 3.55:1 gear, a 26-inch-tall tire, and a 0.76:1 overdrive-ratio. This is one of the most valuable justifications for electronic data acquisition systemseven the simplest ones with just a few channels. For more information, please see our Full-size or RC, selecting the correct gear ratio is critical to drag-racing success. This guide is perfect, check it out here Gear Ratios Guide. One way to do that calculation is simply to multiply the Gear Vendors' overdrive ratio of 0.78:1 by our gear ratio to create our effective ratio: 4.10 x 0.78 = 3.198. You can unlock custom tuning to your car to make almost every possible tweak in order to have the best performance in each different type of race. Slash Spec Racing Setup Guide | Traxxas Simple deform modifier is deforming my object. Drag Slash Tuning Pt 2: How to Optimize Gearing | Traxxas (I can provide the math for this if you are interested). Said in simplistic ways, Short Gears are useful if you are looking for fast acceleration, but reduced max speed. Brain: IQ Evolution/Trick Puzzle Game - All Answers and Solutions for All Levels and Questions, The World's Largest 'Game of Sultans' Guide, Stump Me! @Zoot's answer on this question is very good to give a basic understanding on Tune settings. For all-around fun driving with 2S LiPo power, use the 22-tooth pinion. Provides step by step strategies to analyze, control, and design diesel engines, their systems, and major components. The 3.73:1 gear (assuming the tire size stays the same) barely slows the e.t. You can also look at the data you can also look at the acceleration Gs. Can I gain compression by using older model cylinder heads? Hottest Codes: Active Promo Codes for Genshin Impact: The Full List and How to Redeem Them. If theacceleration Gs drop off you need to adjust your gearing. All You can do is line it back up and run again. Discussion in GT5 Tuning started by Starfirebird, May 27 *Note* This guide isnt meant to get you perfect gear ratios.I made this guide to help Ive been trying to figure out the gear ratios for drag racing.. it just sucks every time I think I have it set up at the top end limit for each car I , Lenco Racing Transmissions have brought more of their racing hardened anodized finish, and a larger choice of gear ratios for perfect fine tuning of gear ratios. As I can see by the screenshot, you purchased tune for BMW M3 E92. I can barley manage 2nd. Passing negative parameters to a wolframscript. It's possible the car might improve traction with a 28-inch tire, but we're unsure how much that taller tire will affect the gear ratio. Gearing is usually about the last stage in race car setup, since it depends on all the corner exit speeds and straight-away top speeds, which depend on the final development of cornering power, braking and aerodynamics. Set the shift light to 9,500-9,600 (rpm)," the guide said. Or, if you even have a single channel of data, just record your speed while youre at wide open throttle. It only takes a minute to sign up. This made me remember when Kenny Roberts was riding for Yamaha. If you have a five-speed box, then you want to select the five ratios that would give you the maximum area under their curves in the shaded area. The 10-speed simulation experienced tire spin (which slowed the 60-foot) because it had much more overall first gear. This generally makes a small difference unless you shift the way a massive amount. (These kinds of gears are also used to lower the driveshaft centerline.) 1: Go to "Transmission Settings" on the car your tuning. Sometimes the simplest, most innocuous question requires a complex and demanding explanation. Showing 1 - 1 of 1 comments. ODR = (Original Tire Dia / New Tire Dia.) You can bring this setting down in order to red-line without This is necessary because vehicles are heavy and require leverage help to accelerate briskly. "Shift before the car hits the rev limiter. For top speed runs: decrease final drive values until the simulated top speed hits a max.
