I know it is old but i got more info now... Ok guys i still haven't gotten numbers to work out for me. 1: How can i calculate Radians from RPM and time, say i have an acceleration of 3,000 RPM in 1.5 seconds, how do i convert? 2. I know moment of inertia = .5Mr^2 but russ's numbers don't...

Thats kinda the problem. On the outermost edge is the ring gear where the starter would engage, not much weight on those teeth. Inside that is a large portion of the mass about 2 inches thick (diameter that is) then inside that is the friction surface that is thinner still (this is really the...

Keep the good stuff coming, I am trying to get an EXACT diameter, i can always rep lug in the numbers u know? I will have a full write up, and will deffintly link it. Intergal catch me on AIM some time: mugen2200

So really I have to work with some time variable... since eveyr car accelerates a lil differently and it is tough to get an accurate time for acceleration in 1 gear, i was hoping to avoid it but so be it... thanks again guys.

No thoughts on using gear ratios?

Yes the motor makes the same power however there is now more availible to the wheels. Underdrive pullys do not MAKE power either but they certainly make your car faster. As well you state the car will redline faster. In order to accelerate the motor faster the car also has to accelerate...

That is too generalized. Assuming that the weight per square inch of tire contact patch was equal then yes it works out. But if the car has (arbitrary numbers) 1 square foot of contact patch and weighs 3000lbs (thats 3K/Sqfoot) and the semi has 6 square feet but weighs 20,000 lbs (thats 3300...

I was pretty happy when i understood F=MA :smile: :wink:

Thats what i needed Russ thanks alot! So to sum up, I need to have my diameter in inches. .5mr^2 (how do you guys do the cool numbers that look all textbook??) is my moment fo inertia. How do i translate a time and RPM into angluar acceleration, that is radians. Once I have my...

Well I know for a fact that the flywheel helps tremendously. The power it frees up is phenomenal, and it cut .2 seconds off my 1/4 mile time. Consider it takes me about 2.3 seconds (thats my 60 foot time so it should be within .2) to get to redline in 1st, that's 7000 rpm in 2.3 second or 3000...

Even just telling me how much TQ or HP is needed to spin a 23 Vs. a 9lb flywheel at 7000 rpm would be helpful!

https://www.physicsforums.com/showthread.php?t=52827 any help here guys, this seems likei t is simmilar to my question... I am a moron help me out please?

I need help figuring out how much HP/TQ is freed up by changing to a lighter flywheel in a car. Specifically the Mazda KLDE/KLO3 2.5L V6 found in the Ford Probe/Mazda MX6. I have listed all needed specifications (I hope). Basically I enjoy physics but am not smart enough to identify and...
