Guys,
Was just taking a look at the www.930s.com website and was just wondering if the specs below which I got off the website was correct or not? the 930S was capable of hitting 197mphr? Is this true? Perhaps 930S owners could answer this?

Engine Type:
Flat-6, SOHC,
2 valves per cylinder Turbo,
Intercooler K-Jetronic
Capacity:
3299 cc
Power:
395 hp
Transmission:
4 manual
Top Speed:
197 mph
0-60 Time:
4.7 sec.
Considered by many to be the finest Exotic Sports Car available in the U.S. With Locking differential, BBS light alloy wheels, HD stabilizer bars front and rear. This 930 received flat front fenders with pop-up headlights and some elements from the ultimate 935, the Turbo Flachbau. The front spoiler, from Porsche's "Exclusive" department, features two little wings to provide down force, an air inlet for oil cooler and two fog headlights combined with two front air dams (for brake cooling). The rear air inlets on both sides (bear claws) are for engine cooling of the mighty K27 turbo charged flat 6 power plant.

395hp??? I thought they had 330, just a bit more than the 300hp Turbo. Maybe there's a Ruf variant that had 395?

Nope this website is purely 930S website.

I must agree with Chris M. 330hp is more like it. not 395hp. the only car in the 930 scheme ( 3.3 turbo ) that had 380-385hp was the 964 turbo S. just my .02c

Sameer

Rey,
Your correct abt the 964 turbo S.

Chris M.

Sameer I checked and according to Total911 Magazine the SE and LE (same car without the slantnose) have 330hp and at porsche.com it says the slantnose versions had an extra 30hp.

Chris,
Thanks. So it is basically 330bhp.

The euro 930S (506 code) in the 80's was rated at 330hp with the following engine modifications: higher boost (1 bar), larger intercooler, better exhaust system, deleted recirculating valve, added oil cooler in the front air dam. The US 505 code slantnose had the identical 930/66 engine as the non-slant 930, which was rated at 282hp.

The 1994 turbo sport 3.6 (C2 slantnose) was rated at 385hp vs 360hp for the non-slant C2 turbo.

So, for the pre '89 930, only the euro slantnose had increased hp over the non-slant 930.

Pat,
the 930S ran at a factory 1 bar? I doubt that. I think it came at nothing more than 0.9 bar.

My factory 87 930S 505 has 330hp and my 79 DP 935 has just a bit over 400hp. I'm not sure which model he is talking that has 395hp unless its one the pre-87,88,89 special wishes cars. I will have to find that on the 930S website and read it.

WERK-I

The '85 930S engine that I tore down nearly two years ago came with the following features that made it unique to the "stock" 930's;
SC Cams
K-27 7006
That would explain the relitively modest increase in output(+30bhp).

Used the same IC as the '78-89 turbos.
Exhaust Heat exchangers same as "Euro" versions.

The service slips I have for the car from the previous owner, stated a 1.0bar boost spring was added by Porsche Service, two years after the car was imported into the USA(1985).

The Special Wishes cars were just that. Whatever the owner wished, if Porsche could provide them with it, they got it. For a nominal fee, of course!

The 964 turbo S shares the similar 3.3L engine. It does have a larger intercooler, hotter S cams not sure about the turbo size though.

Fellas,
You're welcome to agree or disagree, but the info I posted comes from Porsche via Paul Frere. As was stated, werks cars in the early/mid 80's (very,very few came to the states - 100 total is probably a high estimate) could be different, as the turbo was not produced in a US legal version until 1986. The slant car sold in the US (505 code) is IDENTICAL to the standard 930 from an engine and hp standpoint. I've owned both (I have an '87 505 now), and the motors have the same engine code (930/66) with the same internal parts, emissions equipment, and performance. No EGO talking here, only first-hand facts.

The Euro 506 code slant (also a VERY rare car) DID have 30 extra HP from the mods I listed - I'd expect that Paul Frere, who was one of the first humans to test/drive these cars in their era, knew every inch of them.....

FWIW,

WERK-I

I don't know if I'm agreeing or disagreeing with the honorable Paul Frere, but here goes. There are a couple of Rennlisters in the U.K. that own 930SE's. These cars are pre-505, pre-506 era vehicles. The engines are stamped with an additional "S" on the engine serial number(by oil sender).
This really splitting hairs, but once the option 505 or 506 designations were allocated to the 930's, they were no longer "Special Wishes" cars, but optioned 930's with slantnoses unless some exotic engine work was done by Werke I. Special Wishes vehicles were production vehicles that were removed from the standard production line and taken over to the Werke I facility next door. They were modified to the purchaser's wishes with modifications that extended beyond the option list. That included interior, exterior and drivetrain enhancements. What Mr. Frere drove was probably one of those extremely rare Special Wishes vehicles that had exotic engine mods.
Don't know if this clarifies or muddies the waters further, but this is what I have found after researching numerous books on the subject.
Great posts, btw.

Dave,

You're correct WRT special wish cars (of which there were very few). The 505 was effectively a production car which was not typically called a '930 sport' or '930S'. The 506 was called a '930 Sport', of which Paul Frere listed the modifications. The 506 was not US emission legal, so it never officially made it to the US. There are certainly some werks 1 cars in the US that had similar factory modifications, and many, many more cars that were either dealer or tuner modified to similar effect. The 506 engine upgrades were based on the mid 80's factory Gruppe B 930 car, so Porsche was well versed in the performance and durability of the modifications.
