I got the results to the khanacross almost a week after the event. I was really looking forward to them. It's probably better for me to just show you the picture before adding any more comments...
The numbers aren't on the left edge, but this is how it pans out. I was15th outright and only one place off a few juniors. Hmm...
I won't lie, I felt pretty disappointed when I saw that.
But then really, what should I have expected? It's probably got 20hp at the wheels. It's old. The car has no bumpstops. I was driving very conservatively and it was my first khanacross in the car. My first khanacross in a few years. Making it to the end of the day without complications should have been enough.
A more careful look at the results shows the car was slower in the more open tests but more competitive in the tighter tests. Some of that is to do with low engine power, it's also to do with the roughness of the open courses. I was trying not to bottom out the suspension and have the wheels smash the guards.
So I guess this is a measuring post.
Let the bumpstops assume their former positions. Let the driver acquire some spine. More than that...
Let the upgrades begin.
In other news, I've been driving the car as much as possible. Since the khana prep the car is going really well. Basically we found the voltage regulator was draining the battery. The same mate also fixed the interior light and the indicators. Another helped me tune it and it's pretty sweet for a gutless, oil burning, tractor engine.
It's a lot of fun to drive. Just needs more power now.
P.s. My 'off the side of the road' engine case was full of corrosion. So I'm seeking out another one. I've also got some other parts coming from the US.

I made it to the khanacross! And home again too...
I love khanacrosses, but I also have a healthy respect for what can wrong (more on that later). So I often find it hard to sleep the night before and get a bit excited. This was the same last night, but I woke up in plenty of time and headed off to Cataract Pk, about an hour's drive away. My son who usually comes didn't want to, so it was nice a day out.
Truth be told, the weather was pretty much ideal for such an event.
The drive down was great with not a lot of traffic and cool temps. The car was running really nicely and had plenty of poke consider it's tired and pretty gutless.
I arrived in plenty of time and had the car scrutineered. I was rightly told the front end of the car is pretty flogged out. I knew that [grr]. It will get some attention real soon.
Thankfully I was placed in Class A (0-1200) and the supercharger was ignored (usually a treated as power adder; engine capacity x 1.7). Just was well, coz the car had the smallest, most anemic engine there.
I was clearly at the bottom end of the field with old Mazda 121s, an Excel, etc. The top end of the field was made up of two Lancers with FTO 2.0l V6s and a 2.0l powered datto 510. The lancers sounded like porsche 911s at full revs. Awesome stuff.
The first few runs of the day saw me getting used to the car. The tracks were not too rough and I was starting to get the hang of things. The grounds were still a bit wet from a week of rain. So it was a little slippery to begin with. RWD cars were all very sideways.
If anything, this was advantage in the beetle. With the weight over the back wheels, I had great traction with rally tyres. By the third run, I was starting to post reasonable times.
By lunch time I had the feel of the car. I was having to be very careful because there were some big ruts caused by the recent rain, but things were going well enough. I had a cursory glance under the back of the car and all seemed good.
The grounds were set up with two sections. The top was more open and faster, but also more rutted. The bottom tracks were tighter, but also a little smoother and softer. I was particularly enjoying them and to my surprise, I was finding the car was easy to throw.
It's downside, no surprise, was a lack of power.
I'd have to throw it in and then pedal the clutch a little to get it spinning some. This gave me some great, progressive turns. Not much sideways action, but enough to turn the car on hairpins. Besides which, the trick was keeping it smooth (and avoiding the roughest parts of the trails).
After lunch, the two sections of track were set up joined together. This is fun, but it can be treacherous. Halfway through there is a jump and you have to be very careful. I took my run being very careful not to get the car airborne. I made that mistake in my last car and cracked a very strong sheetmetal sump. The other problem being that just after the jump is a big rut.
The fastest driver on the day was a mate who also was helping run the event today. His afore mentioned datsun 510 was leading and he's a great driver.
However, he came over the jump airborne, hit the rut, had the car bounce up again and then... hit the closest tree. Ouch. I saw the accident happen.
Unfortunately, it hit the chassis rail head on and the shell is toast. It also ruined his chances of winning the event outright. Interestingly, his son hit the same tree last year in pretty much the same way. He could have driven to the right of the tree, but the brakes were already locked up. Ces la vie.
After the car was put on the trailer, we had one more run and I packed up to head home. I had to top up the engine and supercharger oil before I left. Truth be told, it probably used it all up on the freeway on the way down. It eats oil on the freeway.
The drive home was pretty nice too. Gorgeous weather and great tunes. The car was a little warm and pinging slightly on the freeway, but no surprise really consider the state of the motor and the big hill I was on at the time.
In the wash up?
Today was a success. The car used about 32 litres of petrol. Got there, got home and we had fun. We really blew me away was how drivable the car was. You could chuck it into a corner with the handbrake and drive it out. I was also getting some nice off-throttle sliding too.
Keep in mind, the car currently has some very worn out 135's on the front. Total cheese cutters.
I'd thought it would understeer, but I only noticed understeer once! Also, the pressures were as follows. 34psi front/40psi rear. It should have been awful and undrivable, but it was great and quite grippy. It even pulled up really well in the dirt stop garages. I have no idea how that works but how cool!
I came home with two realizations about the car;
1. I spent 6 months and lots of time trying to get my dunebuggy to handle this well. Even with all the work, it didn't drive as well as the beetle did today I reckon. The thing is well balanced. The only addition to the car is the camber compensator. I'm genuinely concerned that the disc brakes I'm about to put on might actually ruin that. How funny!
2. One of the guys in the club said, "oh, you're not driving that thing out here are you?". Basically, he thought it was too nice. My response was, "it's a car. If it can drive I can race it". Khanacrosses are usually the domain of 20 year old beater cars. As I was driving home today it hit me, 'in the 1970's, this would have been a beater'.
So, I might not have the fastest car there. Yes, it's old and has some limitations, but not only do I get to enjoy driving around, I also get to enjoy oldschool club motorsport.
The future;
1. New front end. Probably a stock beam without adjusters. With bumpstops!
2. It needs more power. Standard 1600 would transform the car, a new blower and EFI even better.
3. The gearstick rattles. Dunno why. Have to fix that.
4. Seat is crap.
But before I do any of that, I better fix the indicators. Again.

Will I make it to the KC, part 5.
Well, apparently the answer is...
Yes!
I'm sort of surprised. I need to take it round the block in the mo when my wife gets home, but aside of that, I think it's ready.
It's now sporting;
Camber compensator
Fire extinguisher
rear rally tyres
more ground clearance
a running engine
an interior light
and blinkers
So there. Course I just read the sup-regs for the khanacross and discovered I'll be in the same class as over 2000cc cars because of the supercharger, even though I should probably be in the 0-1200cc class. Oh well.
Of course, I'm beginning to think it's kind of like "Roadkill" TV. Where 2 days before the trip, the car doesn't even run. However, the car does run. It's got oil, supercharger lubricant and drove ok today. So all I have to do is make it there, run in the khana, then drive home.
What can possibly go wrong?
Don't answer...
Yes!

Will I make it to the KC, part 4.
What I planned to do today;
Weld on some front bump stops
Trial fit rally tyres
Fit camber compensator
Test drive
What I did;
Fluff around trying to get the engine to start nearly all day.
I was spose to drive the kids to footy practice in the car in the evening, but I couldn't even get it to start for that. Thank God a mate came and helped me sorted it out tonight, even then I couldn't get the timing light to work. *sigh* So I don't have a lot of progress to report, although another mate sorted out the indicators, which now work and the interior light, so that was nice.
I finally got into things tonight. First up I made a new setup for the camber compensator. Basically, the urethane bushes it came with are rubbish. One broke as I tried to take it off the spring the other day...
Yeah, I know. Chinese parts. Doesn't matter really, coz I came up with a plan to make it a lot better. And it looks like this...
This pic shows it upside down, but the idea is this. The red bumpstop prevents the axle tube coming down too low. The U-bolt both locates the axle tube onto the bumpstop and means the compensator spring controls upward motion too. I got the idea from a shoptalkforums.com discussion.
I also had time tonight to trial fit the steer tyres on the front of the car...
This is kind of mixed. The tyre do fit, however. Without the bumpstops, there's not a lot of space between the tyre and the edge of the guard as is. Also, the tyres rub on the body seam at full lock. So really it's a fail and I'll put them on the back. That means I need to find something that fits better on the front. For Saturday, if I go, I'll fit them as the back tyres. I guess I could buy a cheap pair of tyres and tyre groover and carve them up for dirt events. Maybe it's not worth it. Have to see.

Will I make it to the KC, part 3.
Before I took the tyres to get fitted to the rims, I checked if the 7" rims would fit. Glad I did now...
Hmm... Cool in a '70's drags' kinda way. Total fail in a 'tyres not hit the guards' kinda way. Goodbye 7"rims. :o(
I did manage to get these mounted though.
They couldn't balance them, but whatever. I can choose to run them on either end really. I prefer front, but I will need bumpstops for that.
3 down, 3 to go.

Aircleaner done. One unifilter weber sock did the trick. Battery done, topped up with distalled water. New voltage regulator on.
Two down. Four to go.

Will I make it to the khanacross?
It's monday, on saturday is a khanacross. Khanacross is like motorkhanas, but with straights. None of the straights are longer than 100metres, on dirt.
So, I pulled the beetle out of the garage this morning to go to the physio... and it ran on 3 cylinders. Hmm...
I have a few challenges.
1. There are no bumpstops (front cut off, none on the rear from stock)
2. Fire extinguisher
3. Tyres
4. Aircleaner
5. Camber compensator
6. Battery
So far, I have bought an extinguisher. I've got an aircleaner that fits the judson mesh, totally by accident. I have the rear rally tyres, but I'm not sure if the rims will fit under the guards. Have to organize the front steer tyres too. Camber compensator is 2 bits of metal away from being fitted.
Battery, well I need a new one I think. The generator and regulator are throwing 13volts as the revs rise. So they're ok. The battery on the other hand, keeps going flat.
I've spent a few moments cleaning plugs and all seems well there now. Might need to buy some spares though.
So it's not impossible, but the other thing is it's a 58yo car with a tired engine. The event is an hour's drive away. Then race. Then drive home an hour. And of course our other car is showing a few dramas too.
Hmm, will I make it?
P.s. turns out the battery is ok, just needs a little water. The voltage regulator was draining the battery to the tune of about 5 watts. Just as well I had a spare.
