So what does your Z sound like!?

Healthy!! Great video!!

As for noise restrictions, my Z is 114db easy...No problem at Fontana but there would be issues at most of other the tracks in So Cal. I am looking at integrating a muffler under the car for track days.

So which SoCal tracks don't have db limits Ron? Have you thought about putting SuperTrapps in place of the megaphones?

Here's mine with the old low compression engine: http://album.hybridz.org/showphoto.php?photo=1562&cat=509&page=1

Any chance you could post the file here? The link doesn't seem to work (for me).

Hey, can everyone that's posted a vid/sound give us a quick run down on engine and exhaust specs. I think it'll be quite interesting to see how the difference in sound relates to the different setups.

Motor: Rebello Racing built 'true' 3.0L stroker (hair over 3.0L) F54 block

Head: 'Street' porting(not sure on the numbers there) may have to call

Rebello, Compression 9.8:1

Cam: Cam is 495 lift with 285(?) duration.

Intake: Bored SU carbs (50mm) intake manifold also bored.

Exhaust: Header(3 into 2) 2 1/2 inch exhaust into Forza high flow muffler(straight through design)

with a very bad misfiring problem beyond 5000 rpms (faulty ignition) still put down 200 RWHP. Have yet to dyno it since I fixed it. The audio of my car is of course after I fixed it hehe.... engine is at full song now.

Thanks guys. I have the whole autox run from inside and outside. Maybe I'll post the whole 14 meg file since there doesn't appear to be a size limit here and it isn't on the other server it was on anymore.

Dreco, yours just sounds ANGRY. Very nice. Is it really that raspy inside the car, or did you have the microphone right over the exhaust pipe while you did those runs?

My specs at the time:

L28 dished pistons/E31 with 280Z valves (whopping 8.5:1)

.490/280 cam

44mm Mikunis were installed about a week earlier, not even close to tuned

MSA crap header

2.5" mandrel exhaust

$25 Super Turbo

EDIT--tried to upload the whole 14 meg file, didn't work for some reason. You saw the best part anyway ;-)
