It's amazing how well the Tweed held up. Almost every piece of plastic breaks or cracks. I have aspirations of redoing my entire interior. Can't do much about the fading


Definitely!

I think for the most part it's something that falls to the wayside when I hop in and drive. One day redoing the whole thing would be pretty nice, but I'm not in a huge rush. Car drives like a treat, what more do you need right?

Tacking this post here so I have a reference when I need it. I replaced the rear sway on my 931 with a M030 Lindsey bar and adjustable end links.. My links were good so all I have to do is buy some brackets and bolts and I should be able to use this stuff and give the Weissach a nice upgrade.

The outer brackets and bolts are available but the weld-on brackets to the torsion housing I don't think are around anymore -- might have to go with the exhaust clamp method (clever!) when I install this.

So I got new tires yesterday -- 205r50/15 Nitto NT05 -- and they handle amazingly compared to the 20 year old (yes date-coded 0300) Eagle GTII tires that were on there, as you might expect. It was OK for the occasional around-town I was doing, but I have my first track day coming up in two weeks at Blackhawk Farms, and one of the must-haves is fresh rubber.

To get this back on the road I took the not-buckled radiator from the 931 and installed it in the Weissach, but I didn't change the fan switch when I did so -- I should have looked but I thought I recalled the 931 not running too hot. Big mistake. All year it's been 3/4 of the way up the temp gauge before the fans kick on. I have been flipping the A/C on just to run the fans and cool it down on these hot days we've been having. Got a 70-75 switch installed this afternoon, and after a REALLY aggressive run I could not break 1/2 on the temp gauge.

--

So while it was at the mechanic I remember him telling me he had a heck of a time tuning it but he got it running pretty decent compared to before I took it there.

I've been doing a lot of reading the last few days on account of having just picked up a Weber Redline TB. I'm pretty sure the issue he experienced was fighting with the Electronic Idle Stabilzer, described by gohim in this post. I also do not see a plug inside the hole for the mix adjustment screw between the intake boot and fuel distributor -- I bet this is causing me some problems as well.

I haven't decided yet if I want to tackle this prior to the 17th... Might just mess around with it tomorrow, might put it off. I still haven't seen anything conclusive regarding the mounting of the microswitches on >80 model year either, and that's giving me pause too. TBD.

So this Leonard wheel I got while cool looking has turned to crap -- nearly all the leather has flaked off. One day I'll get it recovered in a nice quality brown leather to match again, but for now I just needed a quick solution so I got a Momo Competition wheel. It's slightly smaller, more ergonomically shaped, and most importantly won't fall apart on me! (I hope...)

Old n busted...



New hotness...

Enjoyed your past posts. Your car is almost a twin to mine. I just finished a 2.5 year rebuild. A couple of things you mentioned I encountered on mine. I had the dash redone in a saddle tan. Looks nice. I found a fabric for the seat inserts and also the seats sides. Had the seats partially redone. Got new carpet from Home Depot. They have a brown that looks good. If you want to see it I can send you a couple pictures.

Thanks Ted! They are a really sharp looking car I think. The two-tone tweed is my favorite. I am not ready to do the carpet in it yet but I have seen the least expensive offering from RockAuto and it looks pretty decent, so I will probably go with that -- it's only a few hundred dollars I believe, compared to the upper end approaching a grand or more...

With the help of a friend this afternoon I tuned it a bit. Disconnected the idle stabilizer and dialed in some more timing advance. Got it up to about 13 degrees advanced and it is a lot peppier than before! Set the idle at 700 and got the mix to a nice smooth idle. I'm very happy. This feels very much transformed from before and the flat spot is mostly gone. I've got a lot more pull all the way through the rev range and no knocking. It's not 931 boost giggles, but it's a lot less of a slug.

Do you have a PN from Rockauto. Just interested to see it. I actually dialed in a lot of advance to get rid of the laq. I have been fueling with 91 Octane no alcohol since I started working on it. The engine tolerates the advance okay. I use the no-alcohol gas because this car was full of varnish and I had to remove and clean it. The Alcohol is not good for the old rubber hoses and this car sits a lot. I think the no-Alcohol is good for it.

Another thing. While there is a long story with getting this engine going, the engine had old Bosch plugs in it and they were fully carbon fouled. I bought a new set of Autolight 63 plugs and put them in. Recently we took the car on a couple hundred mile trip and noticed that the idle would misfire more after the trip. I pulled the plugs and they looked good. Clean and not fouled. Just for kicks I cleaned up the old plugs and regapped. I put the Bosch plugs back in and found that the ide smoothed out and the engine acceleration was better. I think I might buy a new set of Bosch plugs to install. Anyway good luck on your 924 and they are fun to drive. I would like more power. Recently there was a posting on the Facebook 924 page about a 924 that ran the salt flats. From what I could find out the engine was a 4 cyl Audi with a 931 head and lots of work. They got over 200HP from a NA engine. I think they got the 924 to about 150MPH on the flats. Faster than I want to drive a 924 but the power would be nice.

Carry on and good luck with your 924. If you know someone that wants one I am going to sell mine. I have too many cars now. ....Ted

Ted, This is the link to the RockAuto carpet -- they have gone up a couple hundred in the last few months -- surprise surprise...

https://www.rockauto.com/en/catalog/porsche,1981,924,2.0l+l4,1263271,interior,flooring,1264

Still not really much compared to e.g. Werk924 at ~$1700 shipped! http://www.924board.org/viewtopic.php?p=401252#401252

Good to hear that your experience with the advance is the same. I've been running Bosch plugs as recommended and always premium fuel. I have not tried fuel without alcohol as the only place around here that has it is Casey's and there aren't too many of those stations. Have heard from other old VW guys that it is the way to go though in the older cars...

As far as more power, for now I am enjoying how this car behaves and I'm waiting to see what the supercharger quest Morghen is on in the Performance subforum leads to. I hope that he offers the connecting bits he designed for sale, as I would love to strap one of those devices on this car. It would be well worth it for the around-town responsiveness alone!

If you're looking to sell, why not post it in the For Sale subforum here? I bet you'd find a buyer pretty quickly.

PostPosted: Sat Jul 18, 2020 1:10 pm    Post subject: Drove at Blackhawk Farms today! Reply with quote

I drove on track for my first time ever today at Blackhawk Farms Raceway in South Beloit, IL. This was for a PCA Chicago Driver's Education event, and I had an instructor in the car with me for the first half of the day. I did five total runs, and only lost control one time, on the last run, three laps before the end of the day!! I set my brakes too hard in turn 4, trying to touch the inside of the apex there, and spun into the grass when my rear end swung out. No damage, nobody was too close behind me -- I was really doing quite well the last run keeping folks off my tail, really gathering more speed than I had the whole day. I got black-flagged and went down the pit lane.. the woman flagging at the starting line asked me what happened and I told her I was just being too aggressive with that corner, and she told me I had about five minutes left. Managed two laps after that.

No hyperbole -- this was THE MOST FUN I have ever had in a car. Other cars bring other feels, but the sheer excitement from driving on a track... whew. I cannot wait to do that again.

One of the things that was really cool about the day is how well the old NA 924 held its own against cars with 3x the power (or more). I was able to consistently hold more speed through the corners than a lot of them were. In the straights there is just no way I could keep up with any of them, but in the corners I watched more than a few drop behind me.. It'll really be great with more seat time, becoming smoother and learning the approach better.

So excited... What an absolute riot!
