square cut gears

I think you mean straight cut gears. The noise will drive you nuts.

 

I dont know if there is something available for the ferrari gearboxes. But if you should search for sequential shiftet or dog type gearboxes. Because those gears are used in these gearboxes. Hewland f.e. builds custom gearboxes and you can get a gearbox done by them.

But inside the car you will most likely only hear that high pitch noise it will overvolume any other sound when speed raises. You dont hear the engine you dont hear the exhaust you dont hear the radio you dont hear outside anything just those high pitch noise. Testdrive a car with such a gearbox befor you consider building a straight cut gearbox into your car.
When customer have such gearboxes and i need to map or testdrive them i use earprotections with communication system to speak with the driver during mapping. I dont think that would be "fun" in a street car. But tastes are different but i would test it to see if it is ok. There are also semi straight gear sets these are a bit less noisy.

 

Good luck with it. Let us know how you make out with your custom designed and built gearbox. Sounds like a cheap and easy project.

 

All that will do is make you explain that there is nothing wrong with your car everytime you pull up somewhere in front of people

 

"What's that noise? I paid extra to make it sound like that"

 

I have it in my Porsche 911 race car -- sounds awesome -- but then again its a race car.

It's loud and will drown out just about all other noises.

Interesting user name and first post...

 

<Ducati dry clutch>

 

Collotti makes a full mkit for everything from a 375 or a 290MM to an F430....
GTO, LM, 512S,,,you name it, they built them...

 

Modena Engineering in Melbourne also do straight cut gear sets for Ferraris.

 

P 4/5 C has straight cut gears. Sequential Hewland. When I drive it I always use hearing protection. If you don't you will damage your hearing. We're going to use the same gearbox in our next road and race car but in our next road car we're making helicoidal gears that will be quieter. As an aside our gear box is a good 50K euros. With custom gears/spares and tools more. Great gearbox for racing as it's very strong but straight cut gears aren't needed on a road car. My 60ies Le Mans cars have straight cut gears as well but we've taken the edge off of the gears a touch by hand honing/beveling which quiets them a bit and makes them tolerable on the road. It also makes them a lot easier to shift. The Hewland has a sensor that cuts ign and throttle for a millisecond when you shift so you don't need to use the clutch but on the road I use the clutch.

There are shops that can make any gear you want any way you want them to be. We can as well BUT the cost is mega.

 

Wouldn't it be easier to fit a set of aggressive mud tires and put some playing cards so that they flap in the wheel spokes? I loved that noise when I was a kid riding my bicycle.

 

Unless you're in a race car... I doubt you'll like it.. And first gear would most likely be as low as a regular 2nd gear ratio, which is kinda tough to use on the street. If you're not convinced, listen to when the gears get loaded in this video.. make it a sequential while you're at it
