a husband and wife both eclipsed 207 + mph in a Nevada open road race in each of their turbo 928s.

I hit the rev limit, fifth gear, in my 951 once.....175 +/- I have read. Once was all I needed.

The scenery passed by so fast, I did not dare look at the spedo much less the wiper blades. The motor had plenty of power (dynoed at 333 rwhp) and was still pulling up to the point I ran out of gears.....and courage.

The car handled the speed with little drama. Other than the rate that the ground passed by, my only other imprint was the feeling of lightness in the steering. I was actually very glad to slow after that run. It was on a very rural highway in the late night (3:00 am).

All I could think about after that run...and still to this day...was, "what would have happened if a deer jumped out in front of me?" It was pretty crazy.

i call that "front end float." not so good. i know it well from a several 135 mph runs from my old '87 944 S 18 years ago.

not so with the 968. it's like brick at 162 mph. i'm sure the car can handle 190 mph.

Bill, I'm sure your fancy suspension and splitter were invaluable at those speeds. I think what I interpreted as instability during my speed run was also just the lightness in steering you felt; I noticed it was too easy to input steering and it made me nervous. I suppose just like how turning the steering wheel while stopped requires more force, doing the same at immense speed requires much less.

Changing lanes? Easy, 125 in the 968 feels like half that in a normal car.

Which model, what modifications? 928 would be an excellent car to build into a 200 mph autobahn cruiser.

I think all 951s need splitters.

I've been thinking for a while about adding a splitter to my 968. The shape of the front end LOOKS like something that would pile up air underneath the nose at high speeds, so it seems a natural thing to add, but I have to admit that no matter how fast I go, I never feel the steering lighten a bit.

they run twin turbos.

I've heard having the batwing and belly pan helps, do you have those on? I have belly pans on mine, but one of my cars never came with a batwing and the other car's broke. I'd like to feel the difference once I find a batwing for my car.

JDS968

My car has one black plastic underbody panel directly connected to the lower edge of the front bumper, then another black plastic panel connected to the trailing edge of the first one, and extending back to the oilpan, and then an aluminum panel that surrounds (but does not cover) the oilpan and extends a bit aft of that.

The "batwing" is that first panel, yes?

Bill

FRPorscheman, The high speed run I did was before I put on the splitter and modified my suspension. All motor and white knuckles baby!

FRporscheman

Yeah, sorry, batwing is the colloquial name for it. It sounds like you have every panel for underneath the car that was ever available - afaik only early cars came with the rearmost metal one. Cool.

JDS968

The car is early, a '92, so it's got all those fun "early" things like the black rear wing and once upon a time it had that extra cover in the engine compartment with the gloves (now probably buried somewhere in an attic...)

Some time in the next few years I'm going to build a complete smooth underbody for the car, including a rear diffuser, and some of those panels MIGHT get pulled in favor of a single piece, to simplify things.

Apex Rex

I've been thinking of doing the same, making a single piece undertray/splitter for my car. I just have no idea of what to make it out of.

JDS968

I'm thinking the splitter and undertray will be separate pieces. The splitter will probably be thicker, tougher, and stiffer, while the undertray will be thinner, lighter, and more flexible.

Love this thread, had my cab 135 top down and that was enough, the951 was a different story and seems a life time ago. Was chastised once for posting what I thought were my mods out of an old file that turned out not to be, hell digital cameras wer not invented yet... I digress,

I posted an old pic of th dash a while back, had the ole girl 173 ish if memory serves. Still had redline and gear but the front started to make me feel like she would flip over. Hit a minor unsettling on the straight and it did not respond well. Last time I ever had the car over 150. No splitter, no rear add ons...

Another favorite was a 55 mph to 140 ish roll size up back in 1997 against my friends new at the time vette. He then understood why I traded the bowtie for my turbo. But that's another post and a story for a younger man...

Cheers, mike
