Close your eyes and listed to this primal audacious scream . OK, you can open your eyes .... and drool too ....
I hijacked this link from qballs post in OT .... strictly for its .... ah .... technical content
The question is ... what is unique on the Modenas exhaust system that produces such great music? Agreed that cam timing and higher rpms , etc. play a large role - but even up to our modest 6600 rpm, is there a possibility of emulating this on a 32v S4?
Free beer to the designer who succeeds!

Whoa, that clip is pretty smokin'! Back in May, I drove a stretch of Italian autostrada outside of Genova that had tons of tunnels, and a blue 360 came up on me. Traffic was heavy, so I got to enjoy the sound of that car for a bit... it was really awesome. The tunnel segments of this video reminded me of that, but you've got to hear it in person!

Oh, and I'll kick in free wine to the designer to meet Garth's challenge!

 

Ferrari's use a "flat plane" crankshaft. That is, the crankshaft throws are 180 degrees apart. Our engines are what are known as "even firing" V8's, and have 90 degrees between throws. Yes, you can make a 928 sound like that. Yes you'll need to produce your own crankshaft and camshafts. You cannot do it with only exhaust work!

N!

 

Very nice!

Garth, you made me and my 2 year old son smile this morning. I think he might be on the lookout for the bikini clad babe next time we wash "red car" though.

oh that was just so unfair at this time on a Monday morning...

ahem... whew...:-)

 

I got a whole earfull of Ferrari's yesterday at Summit Point's new Shenadoah ciricuit (my in car video later), including a 360 Cup car. Awesome stuff. There was a Lambo Ghirardo out there too. Most impressive.

 

OMG. Copied over to permanent storage. That's better than ****.

 

"Flat Plane" never entered my mind after looking at the test pilot ...
So, is the Modena block some angle other than 90 Deg as well?

 

Gotta tell ya, she had me sitting on the edge of my chair , and she can wash my 928 anytime

 

It wouldn't be that easy to make a 928 into a flat-plane V8. Flat-planes need a balance shaft which a cross-plane V8 (like the 928) doesn't have.

 

A friend of mine has a 360 Spyder. The car looks and sounds like this one, but the scenery on the video wins; hands down.

 

Uhhhhnnnhhh...and I'm spent

Shouldn't the length and orientation of the resonance chambers affect this sound as well. After all, the exhaust is only about 3 feet long total and most of it is sandwiched on top of itself with overlapping bends and tucks due to the mid (rear) engine orientation. Our straight line system would probably just rattle a whole lot before it started to sound like that.

 

That's my home 'test section' on Angeles Crest Highway, and I have to say that I've not seen that car or the driver there in person. The tunnels (two in close sequence) are near the eastern end of the western section, a few short miles from where the highway is currently closed dur to some winter mudslide damage. On weekends, this section is actively patrolled; More than a few bikers are typically gathered at the closure, ready to do some fast sections on the way back down. Sheriff parks up there atthe end, in a Yukon, and watches to make sure there are no violations within his sight. Weekdays it's a lot more open. On any given spring day, there are mini-parades of performance and 'test' cars seen on the way up the hill. More than a few magazines regularly use sections for testing and photo shoots thanks to the close proximity to civilazation (such as it is here in L.A....)

A year or so ago, the SoCal group did a mini road trip that ended up with one of the cars riding home on a flatbed, after the driver took some evasive action on a blind curve, and doing some RF suspension damage. Ouch! I've done the drive three times in the last few days, to verify the durability of my TB replace. That's my story, yer onner, and I'm stickin' to it. I need to figure out a good in-car camera mount to document the highway a bit better. Yeah! In the meanwhile, we SoCalers need to revive the evening test drive plan while there's still good light after work hours. No racing, just a fun run in the mountains. It's 40-60 miles or so up and back, depending on where you decide to turn around for the retrurn trip. Anybody interested?

 

NICE Both the car and the young lady

 

I'm down.
