When you know your car is loud...
Alright just thought I'd share. I have a friend with an 85 GS w/ a 6port 13b and a holley 650 carb on it..
He works out at a racetrack where they actually have sound measurement equip. He tested his car yesterday...
103dB at 50ft. OUch! That's the standard method they use to test SCCA road race cars. I think the legal street limit is 90dB.
Hey, it shoots like 4 feet of flame out the back though... that's cool, right?

not that argument again
lol my friend has a sound meter. the stereo in my T-bird (just a good pair of well-positioned 6x9's and a decent amp and headunit) would show 123-124 decibels at the driver's right ear. I used to listen to it that loud all the time, and complain that it couldn't get any louder. That's because driving on the highway, the meter would be pegged at 126dB And that's INSIDE the car...

My friend's REPU was so loud that he got pulled over several times and might have been ticketed for it (I've never asked). It was so loud that a guy working at a local gormet burger resteraunt could always tell he was driving his truck. I could hear that truck across a valley at least ½ a mile away as the crow flies, even over the local road noises and a flowing creek at the bottom of the valley. Man, that was the loudest rotary around here for a while.

well put it this way.. that is the same test Setup they use to test SCCA road course cars. 103dB is the limit for those cars according to him.

I have a RacingBeat Street port header and center section, with a free flowing 2.5" overaxle into a 2.5" in, straight through dual 3" tips (dual 2.5" out).
It has got to be the sweetest sounding ride around. Now for the rebuild, port job, intake, and carb!! Then it will be fast, too.

Flowmaster? ha I laugh at it. For performance, hooker is better, thats like tieing a knot at the end of your headers. It really chokes out the engine. Some stock mufflers actualy will out perform FM.. Your call though that's just my experiance. I switched my old mustang..(the darker days of my life)from flowmaster to raven. The improvement was enough that I put plastic seat covers on my car so I didn't have to keep geting the seats cleaned..lol Raven has a very definate sound, metalic, slightly loud. and it's a free flow muff anyway check them out.

Yeah, I had my car open headers once, but my Dad wouldnt let me leave the driveway with it . It was shaking the windows in the house about 25 yards away when the engine was at an idle . Now, I have RB header and pre-silencer, with the stock blown muffler, and its still fairly loud . Im going to invest in a power pulse muffler soon, hopefully it will sound nice

Let me know how long that works until the flapper rusts to the point where it doesn't seal well.
I was considering one of those, but decided on the "Race Ready" unit - you have to get out, crawl under, and remove three hot wingnuts (they do provide a cheesy-yet-useful wingnut wrench) and a VERY hot plate. But I had the peace of mind in knowing that I'd never have leaks
Be careful to know that your tuning will drastically change wih the cutout open vs. closed. When you open it up, the car will run a LOT leaner.

The flapper ain't that thick.
But I'm ready to weld on a 1/4" thick stainless piece once that's gone. Maybe I'll do that before installing it.
Great idea!!! thanks!
I'm running the EGI, so I wonder if the injection will take care of the lean issue?
It's mostly for fun. Those times I want to scare my local rice racers! I'm asian too, so I can call them that.

Ooh, good call. Hopefully the EGI will handle the lean issue, since it would compensate for the airflow change.
That's one thing I really wanted with that setup, EFI.... It was too much of a hassle to keep going from "track tune" to "street tune" and back again, so I eventually gave up and left it in "track tune" and lived with the crappy gas mileage until the race season was over, then went back to "street tune".

Now... with a car THAT insulated... imagine how loud the exhaust was to make it 126++ dB on the INSIDE of the car. Setting off car alarms was my hobby
