How Do I Make It Sound Like This?

[Coonper 0]

Is it possible to make my mi16 on carbs to sound like a rally car??

 

 

Anyone got any clips of their exhaust note?

 

Forgive the childish question, but i just love the sound of a nice exhaust note

GrpN system??

GrpN system??

 

Ive just bought a group N back box off someone on here.

 

Not fitted it yet mind...

 

Do you think that will make it raspy and rallyish??

It sounds more like induction noise to me.

That sounds 10x better than exhaust noise anyway.

[welshpug 1,657]

to me that sounds like a very expensive engine roaring away down a set of throttle bodies with a pretty normal exhaust.

Its that hollow yet raspy note i like! Sends shivers down my spine! Lol

 

I will see how mine sounds with the group n back box on.

 

Anyone got any video clips of their engine note's? Now is the time to show off! Lol

[welshpug 1,657]

not mine, but feast you ears on this

[Baz 421]

Sounds like you need some ITB's

[Baz 421]

Or this....

I think the trick to get that type of sound is to put in some really lairy camshafts.

Camshafts do transform the induction noise a lot.

Slightly off topic, but I've always noticed (and Top Gear has often commented) that Ferraris sound a certain way. What is it in their design that gives them such a specific sound?

V12's- three small cylinders, into one collector, four times - all doing warp RPM.

The v8's have a flat plane crank which is why they give them a specific sound compared to other v8's, we did do all about the phasing and how it changes the noise at uni but I can't remeber anymore, also why TVR ajp v8's also sound distinctly un-v8-ey

Flat plane crank and you beat me to it.

Don't they sound wonderful!

That white car sounds amazing!!

 

Anyone got any clips of their own exhausts??

 

Im gonna put my group N back box in a bit! See how it sounds then!

You can hear a Powerflow single-box system, with mid-section expansion thing (not really a silencer, I think) in

from Henry at about 2mins in, and a few other bits later on in it. Quite quiet really - it's a stage car after all, and I don't like failing noise test - it's usually around 94/95dB... certainly doesn't sound as nice as any of the examples so far though Edited March 20, 2008 by brumster

This was mine with an OMP grp N twin box exhaust

 

 

This is it when turbo'd with no exhaust

 

Turbo 1

 

This is it when I fitted my homemade exhaust with one jetex box (was running a bit rough as you can hear by the slight miss)

 

Turbo 2

we did do all about the phasing and how it changes the noise at uni but I can't remeber anymore

I think what you are refering to is noise order. A traditional (by that I mean yank V8) has what is known as 4th order noise; put simply it has 4 bangs per revolution, but evenly spaced. An inline four like a pug has 2 per revolution and produces 2nd order noise. It is why you couldn't easily make an I4 sound like a V8 unless you sampled the noise and phased it out by 180 degrees and pumped it back in with the existing soundtrack. You'd still never acheive that off beat sound of a V8.

 

Anyway, I digress, a flat plane V8 has an opposing firing order so it produces mainly 2nd order noise so you could argue it sounds a bit I4-ish.

And as a blatant excuse to post another clip of my car even though its not gonna make any difference to what the OP wants to hear as it is turbo'd

 

Clip 1

 

Clip 2

 

I'll have to take some more as thats at standard boost and its a LOT quicker now!!

[McDude 33]

Bales - your car sounds sweet!

 

2nd order, but literaly chopped up by the turbine blades - a nightmare for designing OE Air Induction, but awesome for that special stage sound.

[Anton green 12 1 Cars]

Love the compressor sound there bales.

[wardy18 33 1 Cars]

im hoping mine should sound well, will know tomorrow when it starts for the first time, lairy rally catcam, twin 45's, magnex 4 branch mani, 2 1/4" stainless pipe into 2 1/2" rear section stainless pipe, only silencer in the system is centre race spec silencer, oh and its had a heavy head skim so high compression, CANT WAIT!!

[welshpug 1,657]

oh god wardy I wouldnt like to be your neighbours tomorrow shouldnt that be 2.5 leading to 2.25 as the exhaust gases cool down and contract thus keeping the gasflow up?

[wardy18 33 1 Cars]

the 2.5 at the end is only a short piece to replace the rear silencer so hopefully wont make a difference, WILL IT?! i have no idea?!

 

err yeh ive got a cherry bomb rear silencer that can be fitted instead of this 2 1/2 rear pipe in minutes just incase it is a little too loud, fully prepared my friend just have a cracked block at the moment
