Stand Tall: A how-to on tall valve covers
As we make our Mustangs go faster we make changes to the valvetrain that at some point necessitate taller than stock valve covers to fit. Some like the "racy" look of taller valve covers but to the hard core enthusiast they serve a bigger purpose. The most common reason to use tall valve covers is to be able to fit aftermarket roller rockers and valvetrain stabilizers more commonly known as stud girdles. However, before you decide to simply bolt on a set of those polished, tall, Motorsport val...

Best 1/4 Mile MPH:		[Ex: 106]
Your cars track weight:		[Ex: 3350]

ET CALCULATOR

Calculate your potential ET from your chassis dyno figures or from total available HP results from the horsepower calculator:

Available Horsepower:		[Ex: 345]
Your cars track weight:		[Ex: 3350]

ET CONVERSION

Convert your 1/8th mile ET and MPH time slip to 1/4 mile figures:

Eighth Mile ET:		[Ex: 7.50]
Eighth Mile MPH:		[Ex: 89.65]

FUEL SYSTEM ANALYZER

Calculate a basic estimate of the fuel system requirement to feed the amount of total horsepower your engine produces:

Total Horsepower:		[Ex: 345]

GEAR RATIO CALCULATOR

Calculate your optimum gear ratio required to help achieve the best ET possible from your combination:

Total HP at what RPM:		[Ex: 5500]
Tire Diameter (Inches):		[Ex: 26]
Finish Line MPH:		[Ex: 106]

TOP SPEED CALCULATOR

Calculate your top end speed and finish line MPH for any given combination of gear ratio and tire diameter (Currently based on stock T5 transmission gear ratios):

Gear Ratio Desired:
Desired Tire Diameter:		[Ex: 25.5]

Disclaimer:

These calculators only provide generalized estimates based on standardized mathematical calculations. In some cases, these widely used formulas are tweaked to better suit what we have learned about Mustang performance. The results are only meant to give you a base idea of your Mustangs capabilities, component needs, and fuel requirements. Only use calculated requirements for a good basic starting point, and work from there. The Mustang Works will not be responsible for damage to your vehicle, for any reason, even if these calculation (especially fuel requirements) are not accurate.
