Every Porsche I have ever known, including my '57 Speedster (with both stock and modified engines), my 2.2L 911E, my original '66 2.0L Solex carbed 911, my 914/6 (with both stock 2.0L and carbed 2.7L engines), ad infinitum.......had one trait in common: they came on at 3000 rpm and were sleeping below that rpm. I have yet to try my Solex cams in my 2.7L high compression MFI 911 engine in my 914/6, but I will bet it will be no different. When they are kept "on the cam", they are a joy, but the rpm must be kept above that number. My 928 is no different; at 3000 it snaps to attention and pulls all the way to redline. Of course the 928 doesn't have much problem below 3000, because of all that torque but good things happen when the engine reaches 3000, (or 80 mph). For that reason, I seldom push any P car below that number. NOTICE: Porsches are NOT DRAGSTERS!!! (oh yeah, someone mentioned that already).

Ron and Jim great advice. Jason

I managed to get my old '81 to dyno at 277 tq sae @ 3525 rpm ... at the wheels, , with minor exhaust work, and otherwise stock intake. (214 rwhp - here.) Bone stock, it was dawdly until 3000.

Even my S³ was a bit lazy when I bought it. After refreshing the sensors, and tuning to stock, it was much improved, and would bark the 225s. Now, it'll roast both 265s by pushing a little too hard n' fast on the 'git-some' pedal.

Interesting post. I was just wondering this myself, as yesterday when I went out for some spirited driving I got a HUGE tire squeel (not just a chirp but a full out squeel) taking off from the lights with my foot planted. But I cannot always acheive this. I noticed a post above that noted it is easier to accomplish this when fuel tank is lighter (not as full), and I had about 1/4 tank left.

I'm glad this has been a help/interesting to others.

Funny -- out of 49 replies, only Dennis Wilson and Brian B indicate that they have a TRUE OB with auto trans.

At this rate, in 3 more years anything that does not have GTS flares will be an OB.

Certainly the 84 AT is a very different animal for purposes of this discussion because of the 4-speed, among other differences. But since it seems to be open season on the question...

With my 5-speed, on the crap tires it came with, absolutely, with a some windup(see pic). With the 17" KDW2's -- not so much. Only in a slow turn with the inside wheel unweighted. As I mentioned in the thread where this pic was originally posted, this was a "special occasion"... I do not drive the car like this, though I do drive it hard.

Very sorry to be a n00b. What is an "OB"?

w3lfd

Mine is a 1982 OB Auto, US spec.

And I just went out and broke the rear loose pulling out of a gas station this evening. Actually, I went a little overboard and almost spun it out... lol

Hence my agreement earlier with the comment about right hand turns pulling out.

Depends on who you ask: Old Bugger, Old Body. I prefer original Biatch

6mil928

That's it only right hand turns for me

Originally it meant "Old Bugger", meaning 78/79 US 928, was coined after EFI was introduced. The issue is confused as the Euro market had K-jet cars until '84. Then the n00bs started calling anything before an S4 "OB" meaning "Older Body".

I'm just ribbing some of the n00bs.

Kidding aside, I think that classifying all cars from the 229hp 16-valve CIS in '78 to the 288hp 32v 86.5 which is basically an S4 without the newer bumpers as "OB" overlooks a TON of development work that Porsche did over the years. Lumping all of these very different cars together seems kind of like saying "Well, it's not at least an S4 so it's not important to differentiate the various characters of the cars".

However, one has to recognize that time marches on, there is momentum in the dilution of the term, and I'm over it. I just can't resist ribbing people about it now and then.

I think I just got a tear in my eye

dskippy888

My bone stock '86.5. Is this what it's supposed to be like? Because it feels like heaven.

I've occasionally managed to lay a bit of rubber in mine, but it isn't US, nor an OB, its an 84 euro S2...I have a wee bit more torque than a US OB(which I actually thought meant 'Old Bugger' CIS injection) but even still I usually only get a chirp from a standing start in the flat and dry. Sometimes it's a bit disappointing but like everyone else has said, its 0-60 is the only time it is less than flying.

Interestingly enough, at a recent American Muscle Car meeting (60-70 american cars are really quite big over here) one of the guys pointed out that while his car could easily do 200kph in a straight line, the 928 could do it around a corner...

Dennis Wilson

I was recently reminded by WK of a little more history of the term "OB". Back during the Porschelist (pre 2001 Rennlist) Geno (RIP) started calling the 78 and 79's "old B@stards" but John D's Lyrus system kept rejecting the name. Jay Kempf subsituted "Bugger" for "B@stard" and Lyrus and John D were happy.
