787b (4 Rotor) Sound From Single Turbo REW - Is It Possible?
 
So first things first - http://www.youtube.com/watch?v=F_kEe...eature=related - Which even earns this icon:hitit:

I'm wondering if there's an exhaust/muffler/silencer/tricks/etc.. to get this sound from a single 13B REW? I'm thinking the 787B was not muffled at all, and that high pitch screaming the result of frequencies generated by 4rotors complimented by insane amounts of RPMs. I think this 'turbine' sound is the only thing that sounds cooler than the pissed off angry "Im going to kill you" engine tone.

Some Tubi equipped Ferrari's and Lamborghini's come pretty close to the sound, but even *if* they made a muffler which would fit, it'd be hard to justify spending the $2500 for it, as per the price of their other inventory. Heres a sample: http://www.youtube.com/watch?v=a2WYcwsDHU0

I've just recently discovered muffler silencers, but from what Ive seen so far they're best suited to keep the neighbors happy :)

I do have the cool dentist-drill sound from under the hood, but its soon overtaken by the low & loud growl emitted via 3" piping through 2 mufflers.

I had thought perhaps a metal "blade" or 2 secured in the tailpipe, much like blowing on a blade of grass in concept, might make the sound. Being thin enough shouldnt effect back pressure much. Or perhaps 2 Apexi N1's or Borla Xr1's would sound just as badass in their own right?
Before I ruin something experimenting, I thought Id ask here if anyone knows anything more about F1-sounding rotary ? Video/sound links, theories and experience sharing appreciated.
Thanks in advance!

At first I thought you were joking.

I then realized you were being serious.

You're an idiot.

Yes you too can have the sounds of a real turbo vehicle on your very on naturally aspirated car!

The turbo sound whistler, inserts into your exhaust!!

Multiple kazoo's inserted into the exhaust will produce this effect as well.

+1

OP:
787b sounds like that because it's a 4 rotor N/A, closest you can get would probably be by ditching the REW for a 20b and going N/A. That or a 4 rotor kit.

I had the honor of seeing/hearing the monster first hand at the Mitty this year.

It sounds like it is tearing the very fabric of reality when it goes by on the main straight. :)

It's actually really easy. Take a sound clip and loop it on a cd. Then link your volume to the TPS. Then get some huge speakers mounted under the car behind the gas tank. Haha

HAAAAAAAAAHAHAHA not a bad solution

Sounds like you need a "Motec tuned exhaust"

Get your exhaust tuned by Yamaha?

notveryhappyjack 05-10-11 06:23 PM

not being an ass but that sound comes from having 4 rotors, i don't see you getting the same sound from a 2 rotor with any exhaust

The 20b has a more distinct f1 sound:

So then perhaps either of you would be kind enough to direct a small fraction of your superlative wisdom as to exactly why its impossible. Though given how quick you are to insolence, Im not expecting you'll share your genius openly or freely. The idiotic thing is to not ask.

*It go WOOOOOOO WOOOOOOO* - F*ing goddamn hilarious!! It was worth the entire post for that alone. I regret nothing

Thanks for the constructive posts. Id love to see that 787B first hand. Sounds like it must almost a religious experience to see live

As it should be.:icon_tup:

13b @ 18000 rpm will make that sound.
