Strange, I can make my '81 kick the **** end out anytime and it is very predicatable in its behavior. It has a very clean fish tail slide from side to side and generally smooth enough to just palm the wheel and toggle the throttle to set the depth of the slide desired. Only on a 180 hairpin turn/slide does it require two hands and lots of elbow room to go lock-to-lock and back when she goes orthogonal to the direction desired.
I thought this was normal, cause it can't be the driver.

If you're not particular what's under the hood and you intend to thrash it by drifting, you should consider conversion to cheaper power. Checkout http://www.renegadehybrids.com/

As somebody said; I do not think the 928 would be a good drift car.
As somebody said; I would not go down the route of engine power increase - I would go for reducing car weight, this is cheap to do and gives you a much improved power/weight ratio.
Throw out the a/c, the air pump, the power seats, the rear seats, the electric window motors; the central locking, all glass, the tools and the spare tire, sound insulation, head light rotate mechanism add a smaller battery, smaller fuel tank. Now you are 300 Kilos or 20% lighter.....

FWIW... aside from my own experiences trying to pull the car back from an extreme full-lock drift, I have seen other info like the posts in this thread that led me to believe that my observations were not exactly unique...

Go for it! The 928 community will benefit from innovative people trying new things, no need to be so negative, guys!
I had cheap crap tires previously on my 928, with a very hard rubber compound. It was very easy kick the tail out, and keep it there for as long/wide as I wanted. Now, with real tires, it is a bit trickier though...
With the appropriate tires and suspension setup, the 928 will drift just fine. So what if it has polar momentum, it will just be more rewarding to learn to handle.
Innovation is good. Challenge is good. Keep it up!

This weekend we went to sweeden and picked up our Porsche. The ovner was so exited when he heard we were going to rip it apart and build a drifting car and trash it on the track. that he practicaly gave it away.
682USD for a 79' 928 with only 75.800km (47100miles) and 2 owners.. It has been stored in a ideal place since 98 and fired right up with a new batery.
That actualy gave us some problems later, when we pased the customs into Norway.. They would not belive that we payed that litle, and acused us for having false paper on it.. But everything turned out good in the end.
We have a lot of interior parts, in exelent condition that we dont need.. Will sell them if anyone is interested. we are curently looking for a gearbox that would suit our use. Preferably a sequential one..
We're still in need of good advise in how to do this the best posible way.
Our website www..928drifting.com will be online in a few ours..

Having looked at gearboxes recently, X-trac and Ricardo both make sequential front-tranmission transaxles that could be used in a 928, if you have the money and equipment to fab the rest of the driveline yourself. These are very expensive race boxes. Probably need to stick with the stock unit for a while...
Also consider that, for drifting, you want good throttle response. A twin-screw supercharger will supply that better than a turbo setup. Seeing the size of the turbos on the 1000 hp Supra's, its no wonder they are on the rev limiter permanently. If they ever backed out of the throttle, it would be half an hour before the boost came back!

When you post something like this..."We don't know drifting wery good ourself. But we know the basics of how to drive a car.. " I would recommend that you simply strip /lighten the car add a rear hand brake lever put on headers lock the rearend and go LEARN what it takes to drift by doing it .....Robbie Gordon a pretty good race drive recently borrowed Ryess Millens GTO last years USA drift champion and Tokyo Drift stunt driver for an exhibition at Irwindale racetrack .....Robbie put it into the wall on the first corner. GM spent a bunch of money buiding a Pontiac Solice (Roush racing chassis GM built turbo 4cylinder nearly 1000 hp BUT it is UNDRIVABLE so the GTO was used this year. GM built a drag racing engine not undertsanding that throttle control not massive power was what is required ! So I think you need to go get experience to learn what you need to have to "drift" .....A good friend is the race engineer for the GTO and has driven the Soltice. His engine of choice is the 7 liter Corvette small block an easy 600-700 HP BUT with big torque in a Soltice !!

Reminds me, check out the Solstice Hammer by Mallett. Way too much power for that little car, but what fun it would be. They do the Saturn Sky too. Supercharged LS2.

Why?
50/50 weight distribution.
Once you have enough power to get it sliding,
it is very well-balanced.
But don't need to be so outragious with the power levels.
If you go that high, you will break the transmission,
blow out head gaskets, etc, etc...
All you need, is 5-7psi, and the car will smoke the tires all day long.
And be reliable as well.
You may want to just start with a stock 928 s4,
and lighten it, and try it on the track with hard tires,
and see how it drives. If you find you need more power,
then look into boosting it. But it may be a very effective
competitor even without boost...
You do know that there has been a 928 drift car before...

I went to a drifting track day earlier this year. I watched an instructional DVD on drifting beforehand to get an idea of what to do ("Drift King" by Keiichi Tsuchiya). It seemed like a lot of the techniques to induce slides were based on having a lower-powered car like a Toyota AE86 (Corolla).
One technique is to do a "clutch kick" which is exactly like it sounds - kicking the clutch in while you are turning and on the power. The revs go through the roof, and when you release the clutch, it shocks the driveline and sends you sideways. This was a pretty popular method. Another technique was the tried and true handbrake turn.
The reality with a 928 is that you have so much torque that you can send the rear sideways with a little steering input and a stab of the throttle. I was running R-compound tires (which was stupid, but I only discovered at the last second that 16" Design 90's do not fit over 993TT rear calipers) and could break the rear end loose at will w/ throttle and a quick jerk of the wheel.
I also discovered that I suck at drifting but it's a hell of a good time. It's all about throttle control and steering input. Other skills like threshold braking or heel-toe downshifts are rendered completely useless.

If you're new at drifting, use a gutted 928 w/ a stock engine. It'll be a lot easier to learn and you won't have to worry about abusing an expensive motor while you're still trying to improve your driving skills.

Dennis well said...... If you can not drive to the capability of the car why make the car more capable ? And I really believe that the better Road race driver you are the harder it is to learn drifting because you are trying to do things which you avoided because drifiting around a corner is NOT the FAST WAY. And if you abused the tires like that for anything like the length of a race they would BLOW. The actual chassis setup for drifting is more like dirt tracking than asphalt and getting drive off the corner can make the guy following you look bad and make it harder for a guy in front to get away to make you look bad. But bottom line it is ALL ABOUT STYLE and how it looks...Just get out there and do it with the minimum amount of work on the car.

This project has taken more time than we tought it would do. I'm glad to show you that we started our baby for the first time last night.
It's sure got enough fuel.

And time to leave the garage for the first time

Sounds pretty good...I would take that wing off though. Isn't the POINT of drifting to slide the back of the car around??? Don't you actually want LESS traction at the rear of the car??? Maybe that wing is set up like a REAL airplane wing though and actually LIFTS the rear of the car, if that is in fact the case then I guess it has a purpose, if not asthetic in nature...
YMMV!
