Yesterday afternoon a co-worker of mine drove his 1986 SOHC 928 to work. The car was in fair condition at best. Dull paint, weak springs, cracked interior etc. I wasn’t impressed, actually I was a little disappointed as he’s always telling me that its by far his favorite Porsche (he has a 911 a 951 and (2) 928’s)



We hop in and start to head to B/W PKY to give us some running room. As we’re at the light I’m looking for tactful way to ask him how a V8 only produces 215HP. Then the light turns green. HOLY *@#&.! It felt as if we went from 0 – 90 in 6 seconds. 3rd gear winds up to 100mph and you’re at the top of third in a matter of seconds. An incredible rush. I driven a 951 with 335HP and it doesn’t pull as hard as that 928. You would swear that thing was churning out a minimum of 450HP, the pull was that strong. However at 120mph the fun is over. It’s a slow crawl the rest of the way up.



He told me that his car is stock and not running at 100% as it needs some work done on it. I had no idea the old ones w/ SOHC were so fast.



How does Porsche do it?

If it was an 1986, it is a 32 valve car.

Your right JIM.



I misspoke, his car is a 84 not 86. He also owns a 32 valve 928 which is being repaired.



Jim-

Ever drive one?

I rode in the Devek S4 development mule a long time ago. 6.0L, stripped interior, 400 or so HP. That thing had warp drive and screamed like a wild animal. Wow.

Early 928s were not that heavy either...right?

In addition to my 968 I'm fortunate enough to have an '85S 32V 928 and an '88S4. These are very fast cars...surprisingly so. In my '85 I can get up to 147mph in 4th gear in no time!! But as soon as I shift into 5th gear it's like I hit an invisible wall and the car just starts to creep on up to about 155mph. 5th gear obviously is for cruising on the autobahn. I've not had the '88 on the track yet as I'm "getting it right" first and waiting on parts from Germany.



The 968 is much more nimble than the 928 but does not have the break neck torque that the 928 has. However, if you rev the 968 and really row the gears and hit the power curves just right, the 968 can be amazing...but you have to work at it harder. I like both cars. The 968, in my opinion, has a better engineered engine design (actually updated) than the 928 and is quite a bit more reliable because of this (shorter Tbelt, Tbelt guard, etc) Arguably, I feel that maintenance on the 968 is probably cheaper overall too. Both cars' body style are great.



In today's dollars, my '88S4 would have cost about $112K (lots of expensive options to buy on the 928). It's cushy. Our 968s (in today's dollars) weren't cheap cars either, relatively speaking. Probably about $50K or so in today's dollars? Think about what kind of car you could buy today for that kind of money.



If you strip either car of weight and do a few mods, they will scream on the track.



For cheap ($6K) you can add a supercharger to the 928...and easily get 400-450 HP. Then you can approach 200mph and smoke your tires with an automatic at 60mph when the trans kicks down (I've seen it). However, the ultimate car, I feel, is the turbo 968. I wish we could get $6K kits for the 968. But due to the small numbers of 928s it's probably not feasible for a company to make these. RSBarn would be more apt to do something like this than anyone I know of.

could not agree more on the seat of the pants difference, and I would love to have the 928's V8 32v pull sensation in our car, but if you look at the acceleration results between the S4 and the 968, amazingly they cover pretty much the same ground, practically neck in neck from a stand still up to the 1/4 mi.. with negligible differences. I guess it depends which magazine or other published stats you read, because they do tend to be all over the place, but the S4 seems to range b/w 5.9-6.3 0-60, as opposed to b/w 5.6-6.6 for the 968, and 13.9 -14.4 for the 1/4 mi as opposed to 14.2 - 14.7 for the 968. I'm guessing because of the torque the 928 should be materially faster from say, 80-150..but given the gearing I'm not so sure that's the case either.. hmm, must find one to race against <img src="/forum/images/smilies/968/rolleyes.gif" class="smilie" alt="" />

Last fall I had the pleasure to be the lone 968 among a dozen or so 928 at their annual Porsche attach track day at Spokane Raceway Park. I spend quite a lot of time playing with the 928 on the track. We were mostly even on the straights and under acceleration, but I could close on every one in the corners. I have not had the pleasure of driving a 928 and I can't comment on their ability except for this encounter. However, because of their higher weight, I'm glad I have the car I do, especially when driving hard. The 968 seem to be heavy enough already. YMMV.

Stephen and DS968,



I've pondered the printed stats and wondered about the 0-60 times too. I had both cars out today for a "keep'em lubed" run and the 928 "seems to be faster" but in reality, MPH seems to be pretty close for same distance.



Sguy, if you were able to pretty well keep up with the 928s at the track, then that pretty well seals it. The 968 definitely has the edge in the corner and if you can stay close on the straights...logic says that the 968 could edge out the 928. The 928 shines from 40mph to 120mph. Is your 968 hotted up?



That said, the 928ers will claim driver skill made the difference, etc. But the 928 is a powerful car..but also very heavy. Then again, the 968 suprizes me on how much it weighs. I put a rear muffler bypass on my 928 so it "Sounds Like" it's faster! It really doesn't do too much but reduce weight and maybe add a few horses. A tuned Xpipe exhaust is the way to go.



The 928 was never designed to be a track car....the 944 series was. There's a reason for that. Although, even today, a well crafted 928 built especially for the track, regularlly keep up with the newest (non-turbo Porsches....993, 996, 997s. Makes the drivers of the newer cars more than a bit upset to be passed by a 20 year old car that cost a fraction of the newer Pcars.



The easiest way to get added peformance is to reduce weight.



Great cars! Great sport! Great hobby! The only limiting factor is our bank accounts.

Badberry68,



What engine is that in your car? (in your avatar) Looks really interesting.

Very interesting.



I would be shocked to see my stock 68 keep up with that 28 from 0-60

From a 30mph roll I think I'll do just fine. I do recall my first drive in a turbo RX7. It is fast, but much of that sensation came from the low stance and stiffness of the car. Just made it feel much faster then what it was.

I believe that engines a LS1

Just marginally off topic, but I had a brief ride in a CL 65 AMG recently. V12, bi-turbo. The driver floored it off the line and took it up to about 100. Sure, it feels very powerful but it's way too smooth and you really do not not get that seat construction pushing against your spine sensation you might expect in a car that gets to 62mph in 4.4 seconds. And the acceleration curve stays pretty much on the same rate of incline up to the sadly limited 155mph top speed, so no slouch there <img src="/forum/images/smilies/968/dry.gif" class="smilie" alt="" />



Conversely, in a Viper RT/10 for example you feel as if you're being catapulted and punched in the stomach <img src="/forum/images/smilies/968/tongue.gif" class="smilie" alt="" /> while accelerating, and if you would ask me I'd put money on the Viper not just edging, but annihilating a CL65AMG after driving and/or riding in both. Clearly, I'd lose all the money, since the cars have identical performance results.



So I'm thinking seat of the pants is so influenced by suspension, gearing, etc. that it can be extremely deceiving .

Harvey, I have just done the airbox mod and have the RS barn chip, but I also think everything else is up to snuff and working right. On the track, as most of us know, the small details are important for car performance, and driver ability are for big differences <img src="/forum/images/smilies/968/cool.gif" class="smilie" alt="" /> I'd like to drive my car back-to-back with a 928 on the track and actually feel the difference. Any takers?

It is an LS1 from a 2002 Trans Am, all aluminum, makes about 350hp. Great way to save a high milage car.



This is a very interesting conversation though. A customer driving a 928 came into my store a few weeks ago, and of course I initiated conversation about our cars. The first thing he says is: "Thats a four cylinder right?, well at least your headlights are pointing the right way". I never went on to explain that my car had a V8, because I wanted to see how condescending this guy would get. He went on to brag how scary fast the 928 is and bla bla. Never gave the 968 any credit except for styling. Well I did'nt know 968s were in the ball park acceleration wize, I did know the handling was superior though. I'll have to put him in his place the next time he comes in!

My buddy has a 86.5 928 automatic. When I ride with him it is boring. I hate the trans (borrowed from SL MB) it makes the car feel like an older american sled.



The 928 was only a couple hundred pounds heavier than the 968, but it sure feels heavier than that. Large on the outside and small on the inside is my impression of the 28.

I was really hoping that story ended with a race. <img src="/forum/images/smilies/968/tongue.gif" class="smilie" alt="" />
