Oh, like Wash. has a monopoly....

Heinrich's idea aside, I have been eyeing the HF press.

Bill,

I passed what looked like your white 928 on 680 and waved from my rosewood via the sunroof. Traffic was not static enough to stop and chat today.

Cheers,

Andre

I eyeballed it pretty close when I went to pick up my 6T jackstands. It looks like it will do the job just fine, though it may not be up to full-time shop use. I'm thinking I'd like to get one for when I go through my rear bushings/trans/TT but I'm a little tight on space. I'm pretty sure it would have been just the ticket for Matt's TC bearings. Now, where to put it... Consider the extra press tools you will need as well. Most of the ones in the WSM can be improvised or bought cheap if they don't have a Porsche part #.

You almost want a benchtop version of that press. Unless you are doing axle bearings on 'murrican cars, you can probably get away with a tabletop with maybe 2 ft of inside height total. Maybe that will help out with the space issue.

Stuff keeps ending up in my garage. I sold the Explorer, and will replace it this fall with something interesting, like maybe a RX400H that I can turn in to a plug-in car. Of course, with all that "extra" space, mrs dr bob is talking about getting some home fitness equipment to go in there. "There's plenty of room!" me: "Yeah, where you usually park your car!" Apparently there's a BIG difference between her idea of "press" and "lift" in the garage.

Andre - that was you! I waved back. The traffic was a little too thick to play catch-up.

I think I once saw you a year or two ago about the same place on 680 when I was riding my old Honda CBX motorcycle (red with 6-into-6 exhuast pipe setup) heading home from work. I rode along side your car for a while, gave you a big thumbs up and tried to hand signal that I had a 928 as well, before I got off at the Diablo Rd exit.

I cleaned out a side shed area that is attached to the garage. The press can go there. I am thinking about changing this shed, which is really part of the garage, so the access is from the garage rather than outside. Simply cut and frame an opening in the wall.

SharkSkin

Bill, sounds like a great place to park it. BTW, removing the stabilizer feet would allow you to store it in a much narrower space, though you would then have to tie it to the wall.

Bob, Good idea, but bench space is at even more of a premium. If I do get one of these, it will probably be hand-trucked out to the shed in the backyard when not in use if I can't find a spot in the garage.

Bill Ball

Taking the Durango to work tomorrow so I can haul home the press.

SharkSkin

WTG, Bill -- It will probably pay for itself with the first two or three items you use it on -- What did Matt pay to have his TC bearing presswork done? Plus time, gas, etc...

Yes once you have access to a press pounding on front wheel bear races which a hammer and chisel just seems so brutal ! Give a 5 year old boy a hammer and it is amazing how many things need hammering the press is much the same ...

Took the Konis for shock dyno. The shop is at Infineon Raceway and the owner was very knowledgeable, although not specifically about 928s. He rated the springs and dyno'd the shocks. His conclusion was the spring rate is too HIGH for the shocks. The Konis do not have enough damping to handle the sport spring spring rates. He recommended I reduce the spring rate.

This may explain why my handling deteriorated when I got the Konis. I misinterpreted the poor handling (wallowing, bottoming) as weak springs, when in fact, the Konis seem to work better with weaker spring rates and can not dampen stronger springs like my sport springs (rated at 450/300). So, it appears my sport springs are still there but the Konis may be a poor match. He thought the Bilsteins would be better for these springs.

This also may explain why George Suennen's car handles like a dream. We believe he has standard springs. It's confusing for a novice to figure out as George's car feels more controlled and I don't quite get how my strong springs would allow the car to feel more loose and wallowy and bottom out. But somehow with weaker spring rates, the car is more controlled with the same shocks.

These are new Konis. They dyno'd pretty evenly in the rear, but one front shock was noticeably weaker than the other. One thing he did not like is that they had very little adjustment range, most occuring in the last 1/4 turn. Also, in the fronts the damping was linear from low speed to high speed, so the shock had very little low speed control. This changed little with adjustment. The compression damping was very weak. At full hard the rebound damping was still linear and finally decent, and the compression damping finally developed a "nose" - a rapid ramp up in compression damping in the low speed area followed by a flattening at high speed. This was a pretty good result, he said, BUT it is wrong to have this at the very end of the adjustment range. Yes, adjusting rebound damping affects compression damping in these shocks.

So, without changing the springs, these shocks need some work - custom revalve. I think I'm going to try the Bilsteins on the sport springs just for science. The I want to look more closely at George's setup.

Bill your Koni's are the adjustable type? Internally adjustable or external?

My car has stock springs and Konis, and it seems more stable in high speed corners than in a straight line. Now I vaguely understand why. Of course my steering seems solid in high speed corners and as the speed decreases the stability decreases. So the steering is my problem, not suspension, methinks.
Thanks for the lesson, Bill.

A couple very large concerns from your post bill:

1) Konis are not as good as they are billed?
2) Quality control between units is not so good?
3) Konis are sold with 600/400 - where did you get these konis? Because I bought mine separately from the 600/400 hypercoil kits. If 450 is too much, 600 will be worse.
4) Adjustment only in the last few percent of the range? Not good either.
