Slight downhill run and I saw an indicated 295kmh (prob 280-285 actual) and yes it was white knuckle driving. I vowed never to do that again in that car. 1.0bar and exhaust job. Stock gearing Euro spec 3.3. Might point out that I've been a passenger in a 996TT at that speed and I wish the 930 had that sort of stability at those speeds.

Man, you are so lucky for getting off with a warning doing 150 mph, DRV2FST. Thanks your lucky star.

Yes I was very lucky. I think it helped that I was in a black on black 930 and one of the local cops also drove a black on black 930. I think they had not called it in thinking it was him until I stopped.

I customarily have a set route I take about once a month. I might see 3 or 4 cars in the 62 mile loop. Great roads no traffic what's not to like? 4 or 5 years ago my best friend and I decide to take another route because I wouldn't be able to drive the car for the next couple of months and we thought we'll try something different. This route is not on FM roads so there is more traffic. A car every 3-4 miles. We ran the car up to 170 and cruised there for a time because we could see ahead several miles and started backing off. There was a crest on the horizon so I backed it off some more and a Highway cop pops over the hill. I clamp down pretty hard on the brakes and am already pulling over as he passes me with his lights on. I'm thinking I'm going to jail. He gets out comes up to my car and asks me if I had an emergency. No sir, just out for a Sunday drive. He tells me he clocked me at 93 and he is going to have to give me a warning. A WARNING. I could not belive it. In parting he told me I might want to find another place to drive on Sundays. I haven't been back on that road since.

Man are you crazy, you use to speed in VA??? That is the only state where I DON"T speed... the cops there right each other tickets!!! No radar detectors either...I hate going through VA, only for that reason, otherwise it's a damn fine place.

My old partner lives in VA and is now a local cop and he has horror stories of guys writing EVERYONE, including military (right of the plane from serving overseas), LEOs, relatives, etc. When I managed an account in MD, some of our guys were MD police and troopers and they had been written in VA, so I can imagine what they do to John Q Citizen

20+ MPH over the speed limit or anything over 80mph = misd. reckless driving (I am not revealing how I know)....I better stop I am getting the sweats

The guy I bought my 94 3.6 turbo from is a TN cop and he was pulled over somewhere in IL doing 176 mph. He topped a small crest in the road and there was a speed trap ahead. He flashed his badge and got off with a warning.

Nice, but try that in VA and he'd have gotten the CHAIR, badge or not. The Trooper I got would give Michael Jackson a kinder reception if he showed up at his kid's next slumber party, than he gave me for 82 in a 60!

Glad you enjoyed it...ya should have been there, looking back it really was hilarious.

In the end, I had to get an attorney and come back to VA. Plead to speeding the violation(no NY points), my company paid for eveything and I turned it into a paid 3 day mini-vacation to see my old partner and family. Lemons to lemonade, that's all!

Anyway I apologize for the hijack, I guess around 150mph in the 930. It was getting a little iffy, so speedometer glances were few and far between. Maybe with the corner balance, good alignment, suspension upgrades, lowering, weight reduction and big tires, a retest is overdue.

By the way my speedo is not too far off... maybe 5mph at 120 or so, verified by GPS. Some guys say they are WAY off, like 10-12mph.

What kind of stability issues are you guys talking about at speed? Is it a problem in holding a straight line, feeling like the car is going to go airborn, or just the way the suspension handles the bumps at 180 ? ... or all three?

Mine felt very nervous at warp speed. It was hard to hold in a straight line. You can really feel that rear spoiler working. I reckon the suspension handled the bumps etc ok, it was just....twitchy.

I hit a small elevation in the road at 140+ and the car got airborne. Apparently it rotated slightly while in the air because when I touched the road it corrected it's direction very quickly. That will remind you of your mortality.

but as long as the road is flat it felt stable enough. I imagine improved aerodynamics would help substantially to stabilize the car at 150+ speeds.

The tail is the Turbo S tail. The spoilers are the Ruf style. Stock my car used to hunt all over the road at 150. Now at 150 it is a stable as it used to be at 90. The spoilers made all the difference in the world.

135mph on the back straight at the Glen this weekend.....140mph indicated on speedo. Had a hard time slowing it down for the Bus-stop at that speed though because had to brake deep into the first corner to get there.
Was still pulling hard up to that point.

La Carrera Classic (open road race that used to be held in Baja from Ensenada towards San Felipe and the reverse in the fall) - 3.3 based engine with spearco intercooler, k36 turbo on 935 headers, cams, 105 octane, 1.2 bar 2400 lbs 935 front end with air gtu rear quarters and imsa gtu whale tail , 16" rim large diameter BFG Radial T/A and a 14 mile long straight. Yielded 195-205 mph about 500 rpm shy of redline (7300)
You are pushing a LOT of air at those speeds. You also have a seemingly long amount of time to realize how dangerous it is. Thoughts go thru your head like " At this speed, if a cv broke, it would come straight thru the aluminum rear decks and ..." At this speed if a tire blew, we could flip and bounce x # of times..." At this speed... and so on

Modern aerodynamics are sooo much better than yesteryear. Though a small shop born effort like ours was very exciting, and the road was "officially closed", this is not something i would repeat again without more adherence to what the factory proved with a full 935 package to keep the car on the road

I have no idea as to hp- This was in the relatively early days of getting more hp out a turbo's. The largest intercooler at the time was the garretson/ andial unit and we knew that was not enough. We used 3.2 heads, 934 cams, 3.2 intake manifold and welded bosses on top of each log. I had a real 934 fuel distributor (the one with the alloy cone instead of a plate) set low in back of the passenger side chain box with a simple screen to keep the large debris out.
We ran 3 fuel pumps per circuit x 2 with a 27 gallon cell (when you are out in the desert there are no pit stops) for supply. Though we were doing this from our shop, it was still a shoestring effort. Dan at AIR was kind enough to help us with left over front bodywork from one of newman's 935 (yeah PLN !) as long as i bought the rear parts from him

So the car was fairly slippery, if porous. If i had to guess? 600-620 ? the cis unit could only flow so much and we had the pressures set to really dump fuel into the motor. The flames on let off were not Smokey the Bear friendly

Those slightly curved side rockers you see on the 935's? VERY much there for a reason, one year we took a nice line into a long curve at about 140 and the car drifted a LOT more than expected. This was without. Next event we had them. Not the kind of excitement i was craving for

We found out later that a belly pan would help in a subsequent west to east La Carrera Classica- gave us much better stability and confidence

So the car was

We taped up all the gaps on the front end, blocked half the oil cooler opening, and even taped the plastic door windows shut. Even so, the myriad series of little holes and gaps left over were enough to pressurize the front compartment so the flip over gas flap cover (aluminum plate on a hinge) was standing straight up at any speed over 160 ! The thin plexi side windows were bowed inwards. Important lesson when setting up a race car; porsche put all those seals and plugs there for a purpose

This is what can happen when you catch air at 140mph on a two lane road. The owner/driver was beyond lucky to walk away with minor injuries.

I'm not against speed at all but we do need to be reminded from time to time that bad things can happen to good people.
