F1 Bark

I figured out what exhaust note I want. The F1 fans are familiar with that barking exhasut note when the drivers peddle the motor,

And ideas how to fake that sound with a 12a?

Yes, glue 2 of them together. You're not oging to get a 12a to sound like a F1 car. You need at least 3 rotors to come close to that sound.

can't be done. F1 cars run with almost no rotational intertia. I saw an interview saying that a F1 motor can go from 19,000rpm to zero in .2 seconds. There is no way to get a 12a down to that kind of rotational intertia, so you can't get the exhaust bark.

I forgot to mention that since the exhaust pulses are 180* offset, so they tend to cancel eachother out. You need an unreal 4 rotor to come close to a F1 sound.

Scoot was able to come sort of close.

Basically, like Hyper says, you need at least three rotors and a light rotating assembly.

I almost can 1-up you on your scoot video, but i cannot find the link. It was the Scoot in action on track.

Someone said 3-rotors will be close as you get, i think 4 rotors is the only real way to come close.

and id say the rotational inertia in f1 cars is not as responsible for the exhaust bark/note but more so the fact that they are shifting at 19500 rpm and hitting the next gear at what....16500 rpm in hundredths of a second? Id say that has ALOT to do with it.

So get your 12A up to that rpm and let us know what it sounds like

I personally like the exhaust note and shift bark of the 787b

The FOURRE car has probably my favorite 4 rotor sound out of all the ones I've heard.

Nothing inspires me more than the word "NO" or "You can't".

I've seen a guy fit a soup can in his rectum.

So I know that anything is possible. BTW it was at work and I didn't pay to see it.

But thank for all the nay say anyway.

I have always attributed the F1 "bark" to the engine's ability to change rpm's over extremely short intervals. It's the same way that a dog barks, high speed air moving through a restricted area, making a bark sound. It sounds like a person with a bad cough with the "bark" cough. Without being able to expel air at a high enough velocity, a "bark" is not possible. Without a superlight rotating assembly able to accelerate very very quickly through the rpm range, thus accelerating a large volume of air through a constricting area in a short time interval, a "bark" cannot be achieved.

Also, to the OP that says that he saw a person put a soup can in their rectum at work. WTF was this person thinking, and WHY did they do it at work? That's gross...

when they start revving at :44, you start to hear the "bark"

So go for it. Shave off rotational inertia wherever you can. Use an ultra light flywheel, lightened '83-85 rotors, lightweight pulleys, electric fan, peripheral ports, a short runner manifold, preferably EFI, and a well-designed exhaust system.

okay so you caaan do it with a 12A but you'll need to build a perry port engine. then pay rb 2000 to lighten your rotors and balance your assembly. then get really short runners and ITB's and efi. another 2 grand. then a 3lb flywheel. then a 5.25" clutch' another 1500 put it all together and you might get a decent bark. but you won't be able to drive it on the street because it will only want to live above 5k rpm.

Put a F1 sound clip in a CD or Ipod. Buy a mp3 playing deck and some big speakers.

no that's why I said you need at least 3 rotors... FYI That car has a methanol 20B in it.
