How do I know what gear ratio My Mustang has?
Multiply the speed of the car by 336. For example, if the Mustang was driven at a speed of 50 miles per hour, the result would be 16,800. Divide the result found in Step 3 by the result found in Step 4 to determine the gear ratio. Here, 65,000 divided by 16,800 equals 3.869.
What are 3.55 gears good for?
With a 3.55 being a higher numerical number, Garrison says it will put more torque to the tire, allowing for faster acceleration and better performance on hill climbs. However, the tradeoff is burning more fuel through a higher engine speed.
What’s the difference between 3.15 and 3.55 gears?
Well-Known Member. The 3.55 will make the gears seem shorter meaning you will shift more often. The trade off is faster acceleration for less gas mileage with the 3.55’s and vise versa with the 3.15’s.
How much horsepower can 28 spline axles handle?
Thanks! they will handle about 450hp depending on whether or not you are running slicks, and how old htey are, and if they show signs of twisting.
How much torque can 31 spline axles handle?
“This will give you a figure that represents the maximum amount of torque transmitted to both axles if you launched at your engine’s torque peak and dead-hooked out of the hole. A 30-spline axle is rated at 6,200 lb-ft, a 31-spline at 7,000, a 33-spline at 8,200, a 35-spline at 9,600, and a 40-spline at 12,000.
How strong is a Ford 7.5 rear end?
General rule of thumb is about 350 rwhp. The new rear end is definitely not the first thing to be done. A cai, tune, and exhaust make a nice difference. If your planning on 400 hp it might be a good idea to install a complete kit(gears, tlok, 8.8) instead of just new gears and tlok.

Do Mustangs have IRS?

While some enthusiasts decry the move away from a solid rear axle, it represented an important shift for the Mustang moving into the modern era.
Are all Ford 8.8 carriers the same?
The gears are all the same for Ford 8.8s. The carriers usually come in two different sizes, depending on gear ratio. The spider gears must match your axle spline count as that’s where they attach to the carrier. A full locker will replace the spider gears so it’ll need to be the same spline count.
