Excellent job describing the drive. I agree with the double clutching, I do the same with my SC. I want the 915 gearbox to last as long as possible! What an amazing car to drive. Solid, reliable, fairly easy to maintain. And I get compliments driving all the time. Only dudes seem to care though :)
We appreciate your comment, Luke! Thanks for watching and yes, this is not the prettiest old 911 around, but it's a very good and reliable car that can go a distance without any worry at any moment's notice.
Terrific vid! The gauges on your SC and of those eras are beautiful and timeless. The engine note is intoxicating, you can hear everything from the gears to engine pounding away. I own a 987 Cayman S an I believe it's sorta a homage to those old air-cooled 911's. Safe driving !
Thanks for the interest and comment. I agree, it's a visceral and very mechanical and analogue experience. The car is still modern enough to be used in today's traffic. I feel an early 912 would be much more difficult to use in this way. You might want to check out the road trip video too. Glad to hear of the 987 S th-cam.com/video/bl5Cvx-pFQA/w-d-xo.htmlsi=YzZMFUjudjEyiZP3
Two observations about the SC from a former owner. 1. The “sewing machine” behind the rear seat seems to create this sound that’s so relaxing when driving. I seldom used the radio. 2. It had all the fun characteristics of the widow maker without the uneven acceleration and almost uncontrollable oversteer. It was the consummate weekend warrior / daily driver car. Only thing I really ever did was swap out tires on the weekends.
Interesting, I recently bought a 3.2 Carrera, without ever having driven one, and was surprised at how much of the 'boxer note' comes out onboard. I'd never really heard that from onboard in any videos of the aircooled stuff, but I certainly do in this one.
Thanks! Yes, it really is "brappy" when on the power. I have attributed it being increased due to the cat being gutted and the big chamber acting somewhat as an expansion pipe now, just before the exit. When you cross a bridge that has concrete barriers and have your window down, it's even more noticeable.
Looks like an early SC? Very reliable car, but I can only speak for my 82 911SC. Improvements were made through the years. Most noticable was the horsepower. Model year 1978-79 - 3.0 liters, 180 hp - model year 1980 - 3.0 liters, 188 hp - model year 1981-83 - 3.0 liters, 204 hp.
Happy birthday!! Consider a good air-cooled car as a solid investment. The 997s especially the 997.2s will be solid investments too we feel. life is short, keep us posted!!
911SC, first of the great 911s in my opinion, power brakes, aluminum crank case meaning longer lasting engines, I owned a a Red 911SC for five years from 2000. Loved every minute of it. did 80,000 miles on it. in 5 years, aside from normal servicing, my 911 cost $300 in spare parts - replace fuel pump, and remove starter, disassemble solenoid, clean and reassemble then install. I miss my 911SC. Now they are three times the price to buy! I think Porsche should build them again, I lament the passing of the aircooler. Love the 'unique futuristic whirring sound' of the air cooled flat six.' Never get tired of it! It sounded like instant power and acceleration on tap, ready to go! When passing another car at 60 mph, I would drop it to fourth or third and accelerate, then, when I had passed the slower car, and I eased off the accelerator, I was often surprised the car was doing 100 mph in that short overtaking exercise. Had so much fun in my 911SC, I was 41 when bought it and my buddies accused me of having a mid life crisis! Gave up protesting their unfair statements and started saying, well, it's my midlife crisis and I'm gonna enjoy it!
What a great story Keith and you are spot on in everything you say. Just one of the best 911s ever made and super reliable which you might not expect from a car made in the 1980s. especially a Porsche. Thanks!!
@@classicperformance People were often surprised that the K Jetronic fuel injection only had two electronic parts - for start up and warm up, after that, amount of fuel was determined by the weight of air pass through the intake manifold! The 'unique futuristic whirring sound' expression is not coined by me, but was coined by a car magazine writer over thirty five years ago, I used it cos I think it is the best description of the flat six sound. Love the deep sound of the flat six and the straight three (just bought a BMW motorbike cos the straight three cyl 750cc sounds the same). Please Porsche bring back the air cooled flat six. I so miss my 911. So well built, loved driving it through corners, roundabouts, and twisty roads. At the time I owned my 911, i lived in the city. Now I live in the country 10 minutes from hundreds of twisty roads, where 911s are at home. When I was 20 years old in the late 1970s, I owned a aircooled VW, and in those days a young VW driver was simply a frustrated Porsche 911 driver! At 20 years old, I made up my mind I was gonna own a 911 by the time I was thirty. When I was thirty I was no closer. when I was 38, an opportunity came along to manufacture heavy vehicle components for Defense contracts (tank components) With the first contract, I could have bought my 911 there and then but decided to reinvest the money in the business which did for three years, then bought my 911SC with cash in the bank! I had achieved my dream and put it to one side. Now, seeing the vids on the SC like yours, got me thinking about another. Though the current price is eye watering.
2 years after buying my 911SC, looked at buying a same year 930. 1982 model. The acceleration along the freeway was indescribable! Seemed to me it was accelerating quicker than I could depress the pedal! I still remember that ride, I did not buy it, cos I was focused on building up my Defense manufacturing business, and I had my dream car the SC. Sometimes I wonder, could have bought 930 even for a short time then sold it. With my new manufacturing business, I now own a Van with twin turbo! VW Transporter with a 2L diesel. I love driving it, though it is not a sports car.
The prices today are indeed eye watering. The chances of an air cooled flat 6-cyl boxer motor coming back are non-existent because there is just no way to regulate teh engine temps and in turn control emissions. Even the air cooled Harley Davidsons now have water cooled heads for emission control purposes.
First notes, gauges have weird chrome around them, steering wheel is also some strange thing. Headlights are from a Carerra series 1987+. Yes, shifting from 1 to 3 to 5th “around town” doesn’t make sense. Not sure what kind of towns there are in the SE, but I can’t imagine any of them would require 5th gear.
Yes, Sir, you are correct. Those are Bosch H4 headlights, also known as the European headlights to replace the poor performing North America mandated seal beams. Stainless trim rings added to gauges, and funky hard plastic horn center replaced with a leather updated center. I think you would be impressed with an SC and how it drives as well as the engine torque. You should see if you could drive one at some point and give us your feedback.
True Greg, I do enjoy the vintage aspect of the SC and drive it like any other car on trips and daily in nice weather. The 991.1 is an excellent car!!!
Correct, not a garage queen and if you study the video, even the clock still works and keeps exact time. Can't go wrong with an SC if you want a 911 to drive the wheels off of. --unlike the Ferrari guys who always are in competition as to who has the least amount of miles on the car. Thanks for your interest!
Nice car...good drive. I prefer rev matching. Have had my '82 911SC since 1987 and know it extremely well. As such, I base the quality of a drive on the smoothness of a shift, and rarely miss one. It's not about speed anymore, but would love to hear the argument for double-clutching.
Rev match so you don't put extra stress on the synchros. Double clutching is technically reserved for no synchromesh transmissions where you need to match gear speed. An example is a large truck. Or, a British car with a non-synchro 1st gear. Rev match won't do it, you need to release the clutch while you blip the throttle to engage the gear to match the speed of the gear you are coming out of.... or driveshaft speed some say. Thanks for the interest, Wayne!!
Can tell by the way you're holding on to that steering wheel with what looks like part of your thumb and finger, you don't take no messin with strangers, were you a Ranger?
Seems normal. on the Oil gauge there are two indicators, the one on the left is oil level in the reservoir, the one to the right is "druck" or pressure. (german/english). As the rpms go up, the pressure increases up to a full 5-bar indicated. This full sweep is very noticable when the oil is somewhat cold and not up to full operating temps. After warmed up it tops out at 3-4 bar. The gauge is 1,2,3,4,5 an is in a "bar" referenced reading. One bar is equivalent to 14.5 psi, so full 5-bar is 72.5 psi. In scuba diving, bar is also the most widely used unit to express pressure, e.g. 200 bar being a full standard scuba tank, and depth increments of 10 metre of seawater being equivalent to 1 bar of pressure. Thank you for your interest.
I actually replaced the USA standard clunky plastic center with this leather covered piece I found from a vendor in Germany several years ago online for a more updated and pleasing look. We still have the hard plastic original.
Your best valuation is to review Bring A Trailer past sales and auctions. Condition dictates price. You can also look at Hagerty Valuation Guide too. Thanks for the interest!!
The major markets of Europe, Great Britain, America and Japan shaped and dictated high end automobiles for the decade before and after this car and then beyond .....each country did things their own many but the cross pollination of ideas and admiration was there....the purity and focus of purpose is a result of the pre-tech time period.....but it is now seen as the sweet spot of driver focused production

I know, and 55 MPH mandated speeds. That's the government for you in that era.... and the big impact bumpers on vehicles. Porsche did a good job concealing them.
@@classicperformance No one's 5mph bumpers looked as good as what Porsche came up with, to the point a lot of folks will argue those were the best looking 911s ever.
We agree with you, it's almost hard to believe that a series of cars from late 70's - 80's with mandated impact bumpers can have such a following and audience today. Usually cars of that era are of lesser desirability.

The motor was rebuilt down to splitting the case. has about 25k on it after fresh rebuild and no issues with dropped cyls or bearings. I believe what you are hearing is that the catalytic converter is gutted and still fitted to the exhaust system, so a big chamber giving the motor a more rumbly and raspy sound.
@HoosierRooster, you are correct. This car still has the large cat on the exhaust and is gutted, so it has an odd sound not unlike that of an expansion chambered exhaust.

Our goal is to remove the cat and insert a straight pipe or a high flow cat. Good ear! CP

So very true, Joe!! Check back into our uploads and take a look at the project SC we pulled home. th-cam.com/video/xCqKKRzuaM8/w-d-xo.html

Whats with the speedo 85? Soeedo
USA mandate back in those day. All speedos could not indicate greater than indicated 85 mph.
Is the gutted cat worth it? Do you feel an increase in power to go with the sound?
Not sure since it has been gutted for so long. I can say the MPG is excellent!!!

Läuft nicht gut... Da fehlt gefühlt ein Zylinder... So unrund läuft der 3Liter Motor nicht wenn er gesund ist. ...
Hört sich an wie an Lagerschaden. Ziemlich rau das ganze.
The motor was rebuilt down to splitting the case. has about 25k on it after fresh rebuild and no issues with dropped cyls or bearings. I believe what you are hearing is that the catalytic converter is gutted and still fitted to the exhaust system, so a big chamber giving the motor a more rumbly and raspy sound.
Had a 74 911 nice old car but by today’s standard pretty antiquated
Wonderful. Thank you!!
Appreciate your interest and view!!!
There are no similarities between those 2 cars. The SC is a real porsche.
We would have to agree! Thank you!
This car does not sound right to me
@HoosierRooster, you are correct. This car still has the large cat on the exhaust and is gutted, so it has an odd sound not unlike that of an expansion chambered exhaust. We have an identical SC with cat removed and a straight pipe and it sounds very smooth and not raspy. The sound of this black SC is very apparent when you are running against a hard wall such as a jersey barrier and you can hear the exhaust note bouncing off the concrete. Our goal is to remove the cat and insert a straight pipe or a high flow cat. Good ear! CP
