Post those puppies up here. We need some live action footage with a little whine !! :D

Darth_Emma 07-21-2010 05:47 PM

I have a selfish reason for wanting to see those videos. I've been saving for a while (and worked overtime this summer) to make some extra $ for the car. I now have enough money to do either a supercharger or a twin turbo kit and it's getting close to decision time. IPS is putting a twin turbo kit in an L99 this week and they are going to ask the owner if he minds if go for a ride it in when it's done.

I keep reading the + and - of each and I think I really need more than dyno sheets to decide. I need to see/hear/drive? some sc and tt cars to know for sure.

Just sat down at my computer.... Give me a couple hours to cut then upload...

I haven't even seen the vids.. Just shot em and split... :iono:

Holy $hit dude. Seriously. If I could set mine up like that, I'd be finished with my car. That sounds freaking awesome.

I'm waiting for the video on youtube of someone stealing the camera just after launch and posting it up just for laughs. :sm0:

Think about some person who knows nothing about cars and forums and exhaust seeing a guy get out, plant a camera on the ground and then driving off from it like it's about to blow up. :sm0::sm0::sm0:

Darth_Emma 07-22-2010 01:05 PM

Wahoooooooooo! That was fun!

I like how the camera jumped on the drive by.

Thanks!

Luckily, that is an industrial park with no traffic.. 4 lane divided highway.

They were supposed to build a mall there but when the economy took a dive they stopped...

And gave me a safe road to do a little goofing off by myself.. ;)

Maybe he sped up the camera and dubbed audio to match? He was really only doing a few miles per hour. Hell, he may have had time to stop the car, walk to the camera, and kick it to appear as if it was the wind.

Well, It's the stock Maggie pulley so right at 6.5 pounds.. When we added the CAI I actually gained a little boost... So, I'm just under 7 now I think.

Also we've been playing with the mufflers. It was dyno'd with a 3' open muffler that was way too loud.

Then Tom put the 3" chambered muffler on (what I have now) and it should perform the same... maybe better with the increase in back pressure.

After talking to ARH, they want me to put a 2.5" on and I should get a bit better performance...

So my RWHP numbers a a bit of an estimate... Everyone that has worked on my car says I should be over 550 in the winter... ;)

But I'm not quite ready to make that claim without a dyno....

FWIW.

Thanks man.

Hey when you have a sec. Can you help explain why the mufflers should be necked down to 2.5" and how that helps performance.. Back pressure and scavenging..

Thanks!

I heard there was gonna be a new federal law that no more than 15 Camaros can be driven at any one time because of that problem...

Thanks!

Here:

The exhaust gases leave the cylinders of an automobile engine at a pressure of around 60-80 lb. per sq. in. and with a velocity of up to 150 ft. per sec. This results in a considerable volume of noise, which must be reduced sufficiently to make the vehicle inoffensive to the driver and passengers, and to the public at large. This legal requirement is achieved by allowing the gases to expand into a silencer chamber, where the intermittent and violent discharges of gas are broken up and emerge from the tail pipe as a continuous and relatively uninterrupted stream.

The exhaust note of an internal combustion engine is made up mainly of a low- to medium-frequency band of 50-600 cycles per second, and a high-frequency band of 3000-10,000 cycles per second.

The low-frequency vibrations appear to result from resonance between the varying capacity of the cylinder and the exhaust system as the piston moves through its exhaust stroke, while the high-pitch sound originates in the release of the high-pressure gases through the exhaust ports.


According to experts (I usually check with David Vizard first) you should shoot for around a 0.2 psi backpressure for no HP loss in a system.

In our terms, you are trying to use the exhaust to both control noise and optimize the flow IN THE COLLECTOR AREA. Basically you want the next cylinder in the firing order (on the same bank of a motor like your LS3) to scavenge such that the next cylinder does not have to do the work. For your THR22 items such as cubic inch, stroke, compression, forced induction boost, cam specs, etc. come in to play. Whether you go with 1-
7/8 or 2" primaries, use a 2.5 or 3.0" exhaust, necked down or not, a X-pipe, H-pipe or any other combination is best determined by dyno testing or trial and error. I am sure THR researched this prior to putting your beast together.

Sorry, the long winded version. Yes, you guessed it, I am sitting on a boat in an island cove right now. Getting ready to leave and get some dinner. :D

I'd like to try the 2.5" just to see the difference.

Yeah -- it's probably worth a try. But consider that Doug's car about made my ears bleed when he first arrived at the hotel...:bellyroll:

That's a healthy growl you've got there, and I thought maybe you switched them. hehehe...I remember when I made some noise for your kids, Billy got all silent and said, "Now that sounded beautiful." ;)
