A Little Noise

My loyal supporters will recall that I have lost a few readers upon discussing my position on noise, specifically engine noise. To set the stage for this latest discussion, let me remind everyone how this started, and then a decision can be made as to whether or not reading any further will be time well spent.

My first motor vehicle was a Lambretta motor scooter with a 125 cc two-cycle engine. Think, Putt, Putt, Putt. The year purchased, it had been used at Sebring as a communication link between corner stations at the track that we still race on. Since it burned a mixture of gas and oil (one Coke Bottle full of oil for every tank of gas) and had a muffler bigger than the gas tank, it was very quiet. The perfect vehicle for delivering the Orlando Sentinel early in the morning.  Not so perfect trying to be part of the biker crowd in rural Kissimmee, FL. In short order, I had two short pieces of plumbers pipe welded into the side of the muffler and plugged them with a screw-in metal cap. The first cutout on the street. Once the paper route was done and everyone was awake, the plugs came out, and the little scooter spoke with some authority. Not a lot, but some.

Next up was a ’58 VW beetle with a stock muffler. The second day I had it, another VW owner showed me how to take off the two chrome exhaust pipes, remove the fiberglass (probably asbestos) packing inside the pipe and make the 36hp engine sound like it had a lot more muscle. Like maybe 40hp. This was before any kind of nonstock exhaust was available. Extractor exhausts were still ten years away from the speed shops on the left coast. A couple of years into beetle ownership, the weld broke on the #4 exhaust pipe, and the one after the clamp had been loosened on the #3 pipe, the muffler could be pulled out just a little and it sounded like another ten hp appeared. Of course, it didn’t, but it sounded better

A  Porsche 356 was the next car I owned, and it came to me with an Abarth exhaust with four small chrome pipes coming out from under the rear bumper. That was perfect; no modification needed, nice deep exhaust tone, and very long-lasting.

 The 356 was getting expensive to service, and I needed a reliable ride for the last two years of college, so a Volvo 544 was the replacement. It had two mufflers, actually, one resonator in the center sitting longways and one muffler in the rear sitting crossways. Once the rear piece was removed and a straight pipe installed, it wasn’t that much louder, but it had a terrific growl to it when it was downshifted to a lower gear to slow down, just like a ’49 Flathead Ford coming down a grade in second gear.

There were lots of others. Once extractor exhausts were available, I had them on 356’s, 914’s, and even early 911s. Audis, like that old Volvo, always had more mufflers than I thought they needed, so more straight pipes were used. A  later Volvo 142 even got its system shortened to a side exhaust that dumped out in front of the rear wheel. On the driver’s side, of course.  Are we starting to see a pattern here?

There is only one car sitting in the garage with a stock exhaust system, and that is a Macan that I don’t drive and am not allowed to fool with.

 The Speedster has a Sebring exhaust                

                                      

 The Puddle Jumper has an original Abarth muffler                                                

 The 72 911 has an Extractor Exhaust

The ’85 BMW has a stainless steel exhaust that Rick’s Custom built for me years ago that makes great noises, and Pearl, the Audi RS4, also benefited from Ricks’s handiwork before he retired with the installation of an electric cutout that can be opened at the touch of a button.  Even without the cutout, it is short a resonator that says it’s not your Grandfather’s Audi.

As the years rolled along, even the Porsche Factory got into the act. The current Big Dog in the garage (2015 991 Turbo S) has a system that changes tone with the touch of a switch, and it’s not quieter. The C4S that my son, Rob, loaned me for a while to inspire the Turbo S purchase has a Factory loud button as an option. Looking at the system, it is an electric cutout that redirects the exhaust to bypass two of the three mufflers. We both agreed that was a good start, but we have replaced the rear muffler on both cars to provide a little more character.

 Once the Turbo S and the C4S were tested at the track, and both passed the noise limit, that prompted me to take a look at what was on the books in the US that limited the noise on streetcars.

Of the 50 states, only 12 have an ordinance with an actual sound level number written into the regulations. It does make me wonder if Law Enforcement has a dB meter in each police car to actually measure the sound level in those states where an actual sound level applies. The states are :

CA – 95db                                   
CT- 82db                                       
HI-86db                          
MI-95db                       
MT-95db                         
NY-82db                                 
OH-82db                                      
OR-92db                                       
RI-82db                           
WA-78db                          
DC-90db  

These are actually some pretty big numbers when you consider that the race noise limit at Lime Rock Park is 86db, and those are some loud cars. Of the New  England states, only RI has a measured limit, while others like MA and NH say things like “every motor vehicle shall be provided with a muffler or other suitable device to prevent unnecessary noise.”  I’m not sure what necessary noise really is, but it certainly doesn’t come with electric cars, which is probably why I can’t see owning one. NH has a rather strange rule that states “no person shall operate a motor vehicle with a straight pipe exhaust system,” whatever that is. Maybe that was written back in the ’50s when “Lakes pipes” were popular out west or more recently to address Corvette side pipes.  I did see a set of straight pipes on a Porsche when John Ames fashioned an exhaust system using a set of copper pipes on his Speedster when we were at Univ of MD back in the ’60s. As I recall, they didn’t last long as the brazed joints couldn’t take the exhaust heat. I’ll never forget the look of four pipes sticking out the back of that Tub flying up University Blvd on the way to class. Funny that snapshots of life never seem to go away.

 I really like the VT statute that only states: “A motor vehicle, operated on any highway shall be in good mechanical condition and shall be properly equipped.” MA law is as general as any as it uses the: “prevent unnecessary noise” line. It also goes on to say that motor vehicles need a bell or horn for signaling and a lock, key, or another device to prevent unauthorized use. That sounds like it could’ve been written back when quill pens were in use.

 There are 18 states that prohibit the use of “cutouts,” but only four states say that cars cannot have them mounted in the car. Those would be CA, NY, ME, and IL. Since MA is one of the states that only says that you can’t use it, I guess Pearl is in the clear as long as I don’t hit the switch. In case you are wondering if there are any states that really don’t care, there is one. That would be Alaska, where there are no state laws that address exhaust noise; they are regulated locally.

The research I did above prompted me to look at noise limits at some of the racetracks that I have run on in the past.

The track in NH where NASCAR runs, NHIS, really doesn’t have a noise limit. That seems reasonable as it is still out in the woods, and the deer don’t care. Civilization hasn’t gotten close enough to complain yet, but I’m sure that will happen. Another track with no noise restrictions is Watkins Glen. High above the town of Watkins Glen, I suppose that the residents are just glad to have folks stop by to spend a few bucks. There are a couple of sanctioning groups that do impose a limit, but those numbers are in the 102-105 range. Think jet plane takeoff volume as you’re standing on the runway.

Sebring is another race track without any concerns about noise. Another reason why I really like the world’s longest autocross track.

Speaking about autocrosses, we do have a sound limit when we run at Ft Devens. It is a little strange as it is set as a number over the ambient noise level. The rule says cars on the course cannot make more than 10db over the noise level when there is no noise. Of course, there is never “no noise.” I have a dB meter app on my phone (of course, doesn’t everyone?), and sitting in my office writing it tells me that the sound level is about 55db, and it’s quiet in here. That is about what it reads out on the runway at Ft Devens unless the wind is blowing, and then it can easily bounce up to 75-80db. Add a car out on the main road, and the meter will show 80-85. Take the reading far enough away from the course when a car goes past, and it adds less than 10db. It’s safe to say that a 90db limit is about right there. I don’t know that we have ever asked anyone to leave the event because their car was too loud.

 So, I conclude that noise is good. Even the stickers on the rear of a couple of my cars back that up, “Loud Pipes Save Lives.”

The DE Crier says “Get Pumped!”

In my new (and evolving) role as DE Crier I received an email from Adam asking me to pen something that would get people excited for the upcoming DE season.  OK, fair enough.  There are a few ways we can go with this.  “Cooped up all winter, pandemic blues, blah, blah, blah but now the robin chirps, the tires squeal, etc.” would be one way. Or “Porsches are meant to be driven on the track, finally see what your car can do.”  But I’m going to take a more concrete approach and take you through the season, track by track, so you’ll have a sense of what is on tap.  Warning!  (Go ahead and wince, Adam.) This will be one man’s opinion and not every word will be positive. But before we get into that don’t forget about the DE Ground School at Palmer on April 24th. This is a class room introduction to DE pitched to those who have never done one (and includes the ability to do slow laps on the track). Even if you don’t think you want to do a DE why not go (and maybe have your mind changed)? Palmer is a cool place, see your other Porsche buddies, go for a nice ride in a rural part of the state.

All right, back to the task at hand.

The first event is NCR’s two day at Lime Rock. Paul Newman loved Lime Rock and I am a big fan – of Paul, but not Lime Rock. It’s a rare combination in that it is great for beginners and also very technical for the experienced.  But it’s short and there is only one left turn where I have managed to spin twice (which probably signals that I am a beginner so why don’t I like it more?). Also the downhill should be taken flat on the floor in my car but that hasn’t seemed to happen yet – so maybe I’m just a whiner. It is historic, in a very pretty part of CT, has good facilities and is a bucket list track. Stay in Great Barrington which is a cool town with nice restaurants.

Next up is Thompson which is also historic – the oval dates to 1940 and was one of the first paved tracks in the country.  The road course has gone through a number of versions.  Like Lime Rock it is pretty short at 1.6 miles but is much slower (60 seconds is a good lap at LRP, 80 seconds at Thompson) and has more turns. The haters call it a glorified autocross (hey! I was the AX chair for 6 or 7 seasons buster) but it has some nice subtleties and the facilities are excellent. Newer Porsches will see 130 on the straight, quit complaining. And, if you live in metro Boston, it is really close.

After that is the first of the two Palmer events (second one is in September). We run one event clockwise and the other counter clockwise (Anker says “anti-clockwise”). I prefer CCW but that’s just because I’ve done a million laps in that direction. This is a challenging track with elevation changes, off-camber turns and lots of opportunity to go wrong. But don’t because it is also the least forgiving of an “off.”  Facilities are good and getting better.  NER has a great relationship with Palmer and there will be good socials when the track goes cold.  An easy drive from Boston but no close hotels. At the Ware Diner they give you a choice of how you want your bacon cooked.

Back on our schedule after a multi-year break is Mont-Tremblant (use your French and call it LCMT).  This is another historic circuit that you have to get to at least once (it was called St. Jovite when F1 ran here). It is a very nice course with some interesting turns and a loooong straight, good runoff as well. I assume our event will be timed to coincide with the Blues Festival at the ski village which is fun. The geography is a little confusing:  at the north is Mont-Tremblant resort (the ski village), in the middle is the village of Mont-Tremblant (where the track is) and in the south is what was the village of St. Jovite – but now all are called Mont-Tremblant. I’m not fond of the ski village (too Disney-esque, drinks from an automated machine, but the kids will like it and the hotels are more modern) – better restaurants in St. Jovite. Consider camping at the track – a nice lake to swim in.  Pain in the neck to get to with the border crossing and maybe horrible traffic in Montreal (Adam thinks the bridge construction may be completed but I’d still brush up on my French swear vocabulary).

Also back on our schedule is Calabogie which is scheduled so that you do Mont-Tremblant then have a travel day to Calabogie – enjoy your week in Canada! Calabogie, like a martini, is an acquired taste (I really like martinis!). It is long and has many corners that look the same but (obviously) aren’t – after three days I was still struggling. And there is nothing to do nearby. But the hard core folks love it and there will be special programming to help advanced drivers improve (heavy training on interpreting data). I’ll be looking for a volunteer to help me write that one up from afar.

In July is the first of two NCR events at Tamworth.  Great track, gorgeous views – it’s too easy to screw up because you are admiring Mt. Chocorua off in the distance when you need to be hitting an apex. The facilities are not yet first class – no garages and not enough paved parking – but the quality of the track more than makes up for it.  The nearby hotels are weak – better ones a half hour away in North Conway – but have breakfast at Rosie’s and you’ll start your day off right.

Ah, Watkins Glen. What can I say?  The best, just go.  And take the husband – he’ll like the wineries, the Glen, the Corning Glass Museum.

The season ends with NCR’s New Hampshire Motor Speedway event in October (yes, it might be a little nippy). Before we had Palmer and Thompson we did tons of events at NHMS and everyone complained, instructors wouldn’t sign up. Yes, there are a couple of bumps that are hard on full-on track cars and, yes, it is pretty short.  But it’s a fun track, very safe for newbies and it is a hoot being in this huge sports complex where the NASCAR boys go to play (climb up in the stands between run sessions for a sense of it). Along with Thompson, Palmer and WGI it has garages. And there are lots of good lodging and eating choices nearby (have at least one meal at the Makris).

So there you have it:  29 days at 8 different tracks spread out over the season. If you have never done a track day then you need to, damn it!  And if you are a regular then welcome the newcomers into your fun club. One final enticement:  there are socials when the track goes cold and (thanks to the successful ministrations of Pam Mascetta and Judi Mansing) even the most snobby beer geeks will find something to their liking. See you there!

The One That Got Away

Here’s another challenge to you, our readers, to recount your experience with the car purchase that got away for you. I’ll kick it off with my own, actually two cars that got away for me. (send your story to the Submissions Team!)

The first one was in 1975. We decided to sell our fairly new car, a Simca Ti and buy a new car. This was prompted by a rumor that Denmark would increase the tax on new cars from 200% to something higher. Our new car choice was a BMW 316, but unfortunately there was a long wait on that, so we ended up with the worst car we have ever owned, an Austin Princess. By the time we sold it two years later we had gone through a transmission and the paint had started peeling off the car. Other than those “minor” issues it was a great car, roomy, and with a fantastic air suspension. I have always regretted never owning a BMW.

The second is much more recent. In January of 2020 we received an email addressed to the NER board from a woman whose brother had just passed way. She explained that he owned a Boxster that she needed to sell, and could we help her? She also explained that they had received an offer for $15,000 for it and had no idea whether it was reasonable. I responded that I was happy to do what I could and that the first step would for me to take a look at the car to determine exactly what it was. So I drove down to Wrentham where the car was parked, got the keys to the car and the garage and drove over to take a look at it. On opening the garage, I saw that it definitely wasn’t a Boxster, but rather a 996, a C4 convertible, black. I fired it up and pulled out of the garage. I don’t remember the exact mileage, but it was somewhere in the 70,000 mile range. The engine ran will with no smoke. Next, I examined it closely looking for any flaws. Then I opened and closed anything that should. The only one I could find was that the plastic around the passenger electric seat switches was missing.

I email the lady back and told her what the car actually was, and that the offer they had seemed very low. I offered to post the car on the NER Facebook group and see if anyone in the club was interested in making an offer.

Unfortunately, all I got was a couple of feelers from the NER membership and no one was interested enough to even look at the car, much to my surprise.

By now the lady and her brother’s executor were anxious to get rid of the car and they asked me if I would take it for $15,000. I asked my wife, and she wasn’t keen on the idea. She felt that going from owning 5 cars to 6, two of which were Porsches, and one a Caterham, was a bit too much, especially since we only have garage space for 4. It didn’t help either that the car was black, a color my wife isn’t keen on. Also,  this was early in the epidemic, and we had no idea what effect it would have on car prices, so I reluctantly declined.

As you all know I could have flipped the 911 and made a good profit or sold one of our Boxsters and kept the 911.

Chase In the Desert!

After a year and a half driving Rob’s 2014 C4S it was time to give the car back. It wasn’t a bad deal for him either as he had my 2015 Turbo S in his garage in Arizona. There was a tire/rim swap to be done between the two cars so it was necessary to have them both in the same place at the same time , at least for a while. Since the driving season was at full speed in the valley of the sun we decided that it would be fun to run both cars at a PCA Driver Education event when they were both in the same garage.

I set about getting a shipping company to pick up his car in Medfield and buying plane tickets and he worked on getting us into the same Run Group at the DE so we could play on the track together. To level the playing field a bit we put the Hoosier race tires on his car to compensate for the extra 200 hp that the Turbo produced. That was after a few modifications, like exhaust, intake plenum, and Cobb ECU tune boosted the output from 520hp to around 650hp. While I was driving his car Rob and his crew were playing mechanic on mine. With four year old street tires on my car we figured they would lap at about the same times.

 The pick up went smoothly considering that it was in the middle of a snowstorm. It was pointed out to me that modern car carriers are now built so that the sides are open and the drivers door can be used for easy entry/exit. Apparently, in years past drivers had to get in and out of the car by climbing through the window.  For the 300lb driver that picked up this ride that would’ve been a nonstarter.

The trip out to Goodyear only took a week and the cars were finally together. Tires were swapped and the cleanup was done by Louie, Robbie and Tommy and they were rewarded with rides back and forth to school. Louie even ran errands with it after calling me to get permission. Great crew.

With the Arizona Motorsport Park less than a mile from the house the oil wasn’t even warmed up the morning that we drove both cars over to the track. It was chilly as the sun came up but turned into a great day for driving. Our shelf paper numbers looked great on the doors. The only panel done in metal anymore are the rear fenders so my old magnetic numbers have been retired to the back of the garage door. Rob made it easy by requesting numbers 31 and 311, all straight numbers in the Porsche font. Details are important.

                                     

Our advanced run group didn’t start until 9:30 so we had time to go back to the house for breakfast after dropping our gear in a premium parking spot.

The track is flat as a pancake, think big autocross, and over three miles long. With a couple of decent straights the C4S was going to have to be better in the turns to keep up with the Turbo S. The grippy race tires were definitely up to the task. There were to be four 20 minute sessions and they kept to the schedule down to the minute, very impressive.

The first session saw me finding my way, I didn’t want to be the guy who went off into the dirt and there was a lot of dirt. The video I had watched at home was helpful but it was tough to look ahead which what we tell every new student to do at a new track. If you know the track it’s easy to know when to keep your right foot down and when to tiptoe. As I was still learning, Rob was driving away. In the second session I had a better feel for the playing field and was able to keep up a little better. I chased him for a while but couldn’t get around him, he just went way too deep into the turns. He motioned me by to see if I could drive away but I couldn’t. We ran nose to tail the last ten minutes of the session, passing other cars like a train. Great fun.

By the third session it was catch me if you can. I had a better sense of the PCCB (Ceramic brakes) and could brake later that the C4S. Rob was still keeping up well but he ended the session early after his brakes began to fade. Turns out, he also corded a new Hoosier tire, a left front (we were running the track clockwise), so I know how hard he was trying. All in all, a terrific day at the track.

 The Big Dog is now back in Medfield having made the trip on the same truck with the same driver that took out the C4S. Strange how some things work out.

I may give the ’72 a rest this year and run the Turbo S in the Autocross series just to keep the young guys honest. I wonder how the Turbo S would look in a Martini suit? We’ll see.

Meanwhile, Summer is just around the corner.
