Re: Axle weight?
 

I think what everyone is failing to understand here is that lightweight axles in and of themselves are not going to give you that"magical tenth" that everyone is pursuing. Lightweight mechanical parts of any type whether they be engine components, transmission components, rear end components, brakes, wheels etc are going to produce results. Some more than others. But when combined with MANY lightweight performance parts they "MAY" or "CAN" produce the increases in performance that everyone is looking for. The results usually come in the form of HUNDREDTHS of a second in lower elapsed time or TENTHS of a second in increased MPH.By combining the correct lightweight parts for your combination you will eventually get there. If you go with that approach you "MAY " get the desired results you are looking for by using certain lightweight parts and then again it may not work for you.You have to keep trying different things--- its called testing---Just because it did or did not work for the other guy doesn't mean it will or won't work in your car. Only testing will give you your desired results--FED 387

96 Camaro LT1 33 spline 12 bolt. Broke a axle a while back was a Strange regular full circle flange not drilled called Moser and asked for the lightest axles they could make $725 00 later they showed up at my door. Each axle was 8/10ths of a lb lighter than the old ones.hell I was more worried about the new bearings slowing us down than the weight picking us up.

I love these old videos. What we learn is heavy is better if it is located near the center of rotation.

So, fill our drilled axles with lead? :-)

Re: Axle weight?
 

If they are rolling down hill not under power the filled axle wins every time. Not lets put them on a flat surface and powered by a motor. I'll take the light weight ones every time.

Re: Axle weight?
 

Any reduction in overall weight would require less force to accelerate the car. The axle ,even though it’s spinning is still accelerated at the same rate as the rest of the vehicle. Is it possible that is why there is little to no ET reduction from a lightened axle or wheel ?

Re: Axle weight?
 

I was wondering how parts rolling down that board related to an engine having to accelerate that part. Small diameter & heavy will win that deal.

Re: Axle weight?
 

I was thinking the same thing.

I know it's a stretch.....it's covered in the third video, if your brain doesn't melt first. The acceleration of mass is.....the acceleration of mass.:D

Try building engines with a 50 lb crank rule.
