"FREE" Up Horsepower with an Aluminum Driveshaft

"FREE" Up Horsepower with an Aluminum Driveshaft - Dyno Tested!

If you understand basic physics, then you know that reducing weight from a vehicle's driveline will help with acceleration and "free" up some horsepower. We use the term "free" up since the power is already there, you're just helping the engine not work as hard by replacing the heavier component with one that is lighter. The most common driveline upgrade on rear wheel drive Mustangs is a driveshaft. Aftermarket aluminum or carbon fiber driveshafts help reduce rotational mass, thus increasing acceleration and "freeing" up horsepower.

The power that's brought back from parasitic losses is NOT the true benefit. The reduction of extra rotational mass weight on the transmission is significant. Don't forget fuel mileage will be impacted in a more positive aspect of the daily driving experience.

The results were negligible, but what’s important is what you can’t see. The added weight of the old drive shift slows initial acceleration (hence the statement what you feel) and more importantly the wear and tear you save on your drive line due to the initial power transformer under take off. Think of spinning a crank with your arm with a heavy crank versus light. Once up to speed no problem, but that initial start is where you get the payoffs.

Heads up: the car might stall much more easily if the motor is tuned for top hp . I had a speed shop tune my 11:1 331 na with all the bolt ons, they tuned on a dyno… when I was parking the car, yanking the steering wheel suddenly would stall the car. And the speed shop acted like it was my fault for not knowing that would happen (they just didn’t know how to tune). Just buy a blower though, that’s the lesson I learned.

I believe it's not just reducing weight, but no one else has expressed the fact that maybe the carrier bearing robs just a bit of the horsepower from the drivetrain as well. Every time you add another friction surface, there has to be parasitic loss.

Pretty sure lightnings and 03-04 cobra came with aluminum driveshafts stock. I did the Ford performance ds on my 07 gt500 the biggest thing is when you're making 750+ rwhp like I am with a gen3r the stock driveshaft won't hold up especially if you're on fat drag radials like I also am. That was the biggest reason for the upgrade for me but freeing up couple hp and torque and making it Rev faster and drop almost 20 lbs rotational are all icing on the perverbial cake. I could use all the weight savings I can get on my fat 3900 lbs mustang haha. I'm prob around 3800 now and I got some lighter corbeau gts2 seats on the way that should drop 30-40+ easily I might do a rear seat delete also since I never use it and this car isn't my daily. It has a lighter exhaust and an f14 drag pack on it too. I'd like to get her down to 3700 lbs or less without killing street manners or gutting it into a tin can I think that is easily doable.

The thing about rotational mass is that the radius of the spinning object matters. A driveshaft is a fairly poor flywheel because it's so thin. So you really aren't saving much of anything compared to the stock steel piece. Especially when you look at the overall rotating mass-- the tires and diff spin too. This makes sense as part of a lightening program. But power gains are almost entirely theoretical.

The results simply depend on the weight savings of the lighter driveshaft. There isn't' really a blanket "percentage". However, the theory is the same for all makes/models.

Are the yellow dots for balance considerations? Thanks. I’ve got a similar 2014 GT and at 26000 miles I think the carrier bearing rubber isolator is going out and causing the driveshaft to vibrate some. So I may be looking at the same driveshaft install.

@hotchrisbfries Жыл бұрын

A better explanation isnt the horsepower benefit from less rotational mass. - A lighter driveshaft means less rotational mass to be accelerated, allowing the car's engine to transfer power more efficiently to the wheels. This can result in improved acceleration times; you'll notice that the revs tend to "hang less" and more responsive to the shift patterns. - Increased Fuel Efficiency: A lighter driveshaft means less energy is required to rotate it, resulting in lower fuel consumption and improved fuel efficiency. - Improved Handling: A lighter driveshaft can reduce the overall weight of the vehicle, which can improve handling and reduce body roll during cornering. - Reduced Wear and Tear: A lighter driveshaft can reduce the load on other drivetrain components, such as the transmission and differential, resulting in reduced wear and tear on these parts.

I'm looking for multi functional parts forst before i spend $2650 on carbon fiber to save 125 lbs (without doing doors or it'd be like 240lbs total) which is 5% of total weight cut. It's a good amount but if i do things like lighter wheels, lighter tires with performance (i have all seasons currently), aluminum driveshaft, possible rear diff upgrade, exhaust system probably last, then I'd probably save around 400 pounds or 16% in total weight reduction. Then i would start with performance parts like brake kits, cams, etc. I'm doing webber carbs right now.

That tiny difference you suggest is an increase is is well within the standard deviation between pulls on a single car with zero modifications.

I’m addition! You would also need to make sure both drive shafts were equally balanced. I appreciate you spending the time to make this video. However, your conclusion is totally flawed.
