Tom Fitz has said he is coming out with more camera equipment for better video this time too.
The course is half designed now ... this time designed specifically for this venue ... :)
See you there!

That was quick... already at 60 entries as of tonight.
Registered, suspect my car will break the noise limit unfortunately...
...
Come prepared to do something about it ... a Super Trapp, downturn pipe, whatever you can think of ...Quote:

Unfortunately nothing I can do about it for this car without a different exhaust, I will just have to leave if it's over the limit.Quote:

Drive part throttle through the whole course? :rofl: (hey, it would work!)Quote:

Although this is good advice, part throttle will be your best bet.Quote:

R - are there any sort of soft rules for BONE STOCK cars that may potentially break the DB rating?
Cheers.
I think my car is actually louder at part throttle than wide open throttle because at least under boost the turbo muffles it a bit more haha!Quote:

Stupid Subarus...I need another racecar.
The rule is pretty straight in that you have a reading from the sound meter and that is it. The meter is set to "slow" setting (otherwise we would have a lot of vehicles over), 50' perpendicular to where the cars will be passing by (conceivably located where they would be at full throttle), at a height of 3-4', ANSI B (?) std.,Quote:

Bone stock cars blowing over? Yes, the Corvettes with the flaps opening in the exhaust will blow over and I know there are at least a couple of locals who have fixed them shut and I believe one other car that I don't recall. That is one option on some high perf. cars currently available that can be fixed fairly easily from what I understand. I know Tom will be there with his 'vette and has done that to his.
BTW, I like loud exhausts too (pleasant ones that is .. unlike, say, an open exhaust rotary which can be really shrill and just plain noisey), however, we have the issue of losing sites due to loud exhausts (one of the key reasons). But there is also the damage to our ears that we can do via the loud exhaust ... and I mean the workers on the course.
I have an Invidia cat-back exhaust (stock cat is still there) on my street S2000 and it has a removable cap on the end ... which lowers the db. by about 2-3 db making it easily "legal". Without the cap, it has blown aruond 92.5-92.8 db. as per SCCA regs at San Diego numerous times. There is some variation with weather/ambient conditions.
However the exhaust without the cap I find just plain annoying on the street and highway because I have a hard time hearing the stereo since it is "so" loud (even with the convertible top up). And, like I said above, it has been measured almost exactly at the limit of 93 db. (or rather just under). So, really in the real world, why would you want to "live" with such a loud exhaust anyway? I also realize when I was younger I preferred louder exhaust than I do currently but maybe some of that was the lower tone of a V-8 exhaust instead of my 9000 rpm S2k? :)
Remember also, that once your ears are damaged (all you rock 'n rollers), they do not heal. Hearing loss is permanent. Even work places have health regulations for loud environments, ear protection, etc.
So, you might say, in a number of ways, sound limits make a bunch of sense. At least that is the way I see it fwiw.
Does that make sense?
I am also thinking of bringing my car out so we can use it to test the sound meter and the lot environment since I have used it repeatedly over the years at various SCCA events and normally record 92.5-93 db. I do not recall it ever being above and have never had to modify the exhaust so it would be a good measuring stick.
How secure are these spots since they are almost full? I need to buy a new helmet and won't know if I could come till later today. How many runs are expected each? As with the time and 75 drivers, sounds like it would be about 5 runs each.
Really want to do this, it's been too long since I was last out.
The lot is big enough that the course does not lap back on itself. That means we can easily send cars 30 sec. apart and we even tried 20 seconds apart just like the big US/SCCA events.Quote:

Last time with 75 we had 9 runs each. We would like to finish earlier this time so maybe 6-8 runs ...
We also have loaner helmets although they were in high demand ... so better if you bring your own Snell (must be Snell NOT DOT only) rated helmet.

Ill bring a coffee mug, a hack saw, and some duct tape... think we could make it work?!? lol :rofl:Quote:

At US nationals I saw a car that used wire to hold a wet towel around the end of the exhaust with someone soaking it before the car was started. Also another car tried stuffing the end with steel wool but that turned out real bad.Quote:

I've got some thermal insulation we can shove in the exhaust pipe... that will quite it down! :D
Went and bought a new helmet and signed up. :D Looking forward to this.
Driving a different corvette this weekend ;)Quote:

I only blow over because my exhaust isn't stock, I think stock vettes even with the factory performance exhaust are typically fine. The ZR1 at the last event didn't have a stock exhaust either.
Decided to run the RC-F tomorrow. No clue how to change the registration to switch cars, so it's still showing the GLA. Hopefully that won't be an issue.
