Well after a 4-5 month hiatus up on axle stands, my gti is back on the road. I managed to snap a shot of it with all 4 wheels on the ground AND external to the garage. Such a momentous occasion, I just had to share. And its about time I started a thread anyway..
So far it seems the hard work has paid off with all mods working well. These include a rebuilt ABF bottom end with Wossener forged 9:1 pistons (the original reason it was taken off the road), a reco-ed 02A\02J hybrid box with peloquin diff and mkv shifter and cables, a custom hydraulic clutch setup, a couple more gauges, a few exhaust mods so I can get out of the driveway without scraping like mad. The clutch kit I bought came with a 30% lightened flywheel, that's probably the only mod I'm not liking that much. But all things considered, I'm pretty damn happy with how its going.
Great mix of old and new mate, and she looks so clean! A white GTi is always a winner IMO, hope you have some fun with it :)

Great to see a few pics of your lovely gti mate - I was sure surprised at the nats track day to find not 1 but 2 turbo mk1's there on the day - awesome! (I guess I'm not counting my turbo diesel in that mix ;-) )
Looking at your engine bay shot, really does a good job of convincing me to move the battery in the cabby.... mk1 + turbo + FMIC = not much room for anything else :-)
Would love to hear more about your clutch setup - I'm considering an 02a setup for the cabby.

Hey mate, I was surprised to see so many mk1's at the track day let alone 3 turbo-ed ones! Here's the clutch setup, that's a T4 master. Let me know when you're ready to tackle it, it works really well. I made sure all of the pivot points, ratios and the spring match a mk4 golf setup and it feels pretty much the same.
Its off its head :D I just have to get it idling a bit better with the ISV, but other than that its going really well. I really should investigate fitting wider wheels, it can be quite a handful!

Thanks! Looks very neat. I had wondered about getting the helper spring in there, looks the goods.
Might have to come visit some time and take a closer look, be keen to see what you've done with the mkV shifter aswell :-)

Cool work with the hydro clutch setup.
IIRC, a T4 clutch MC is what canberra Pete (and Gareth) have in thier 20VT caddy/mk 1's.

Thanks mate. Now to get your 16v going! It should be an interesting mk1 turnout at the Wakefield supersprint next year by the sounds of it. This years turnout was already great.
That's a beautiful Mk1 there. It'd be nice to see more exterior shots from different angles. It's a real head turner.:thumbup:

Ahhhhh looks sick !!
**** must fly too
What turbo are you using, an what boost levels(psi/bar) do u run with ?
and how much did you torque down your rod bolts & crankshaft cuffs to ?
Your info would help alot :D

I am using a gt28rs running a fairly conservative ~12psi. This turbo is still efficient at around 20psi, but seriously there would be no point. The 2.0l spools it up nice and early so it is quite responsive, and while not exactly "linear", its definitely not one of those Jekyl and Hyde setups. I wanted the power delivery to be something you can realistically use on the track.
The rod\main bearing bolts are just torqued to whatever the recommended torque value is. The rods have arp2000 rod fasteners so I had to look up the recommended torque for them.

I decided to isolate the pod filter so that it isn't sucking hot air from the engine bay. So I made an airbox:
I haven't dyno-ed this motor yet. I really should before the next track day just to check there isn't any detonation going on that I can't hear.

Thanks mate so do I! I plan to head down for the VW supersprint in May, but I'm trying to get down before then as well. Reliability is the name of the game and this motor still needs to be baptised.

Any ideas about other outings before then? I'd be keen aswell, want to get more value out of the CAMS license than just hte one supersprint per year :-)

I haven't seriously looked into it yet but there should be some CAMs trackdays run by other clubs which we should be able to enter, probably just have to pay a small fee for a one-day membership.
I have also gone to private non-cams trackdays which are held frequently, but they tend to be more expensive so it kind of cancels out the benefit of having the cams licence. The last one I went to was poorly organised with way too many cars on the track and there was actually 2 accidents. Someone was telling me about one private group which is quite good though. $250, but there is an instructor available and you even get lunch included and heaps of track time. Its usually on a weekday though. I will start looking into it, I'll let you know if I'm planning on heading down to one.

That sounds like an MRT track day. I have done one before and really thought it was good value especially as they had 3 instructors. It was at Marulan, but they do them at EC and Wakey.

So I haven't updated here in ages. Nevertheless the mk1 has seen quite a bit of activity.
I did 2 trackdays at Wakefield, the last one being the VW supersprint in May. I managed to knock a second off my previous best time which I was quite happy with. The car did not have any issues. All the temps were good, the coolant never went past halfway on the gauge.
But I did nearly burn the car to a crisp! After the last session the car was parked and I forgot to open the bonnet to let it cool down. The turbo was so hot it loosened a zip tie running along the top strut bar above and a vacuum line sagged down and rested on the turbo hotside. I caught it before anything bad happened, but it finally motivated me to make a heat shield:
I should check it out with one of those IR laser temperature guns to see how well it works. Should keep the inlet plenum a bit cooler too.

Here's some in-car from the last VW supersprint at Wakefield. I only managed to get footage of the first session unfortunately, still making some silly errors like a missed gear change, but hey.. Anyway here's a 1:12 from the first session. Everyone seemed to get their best times in the 3rd and 4th sessions when the track temp was good.

The mk1 had its big annual day again at the VW supersprint on the weekend. Due to last minute circumstances it ended up being double-entered as well with a mate also driving. So it REALLY was a big day for a 32yo car with nearly 3 times its original power, and it also had to drive all the way back to Sydney as well.
My goal was to try to break through the 1:10 barrier, into the 1:09’s. In the end I finished with a 1:10.1. The 1:09’s were within reach though, but we cooked the brakes halfway through the day, and after that they were only working at about 75% of their effectiveness. Also, some decent tyre flat-spotting didn’t help either. But, still, not a bad time for a mk1, and it was pumping out 1:11’s/1:10’s throughout the day. My greatest satisfaction however was with the reliability of the car. I never would have previously contemplated double-entering it, and really, it handled the abuse very well. Coolant temp never went over half, oil temp never went over 115C.
But it needs some brake ducting in the future which will be easy to run off the new front airdam. The only other problem I had was some CV grease escaping out of the CV boot and on the straight at high speed it would flick onto the downpipe creating a puff of smoke from under the car. It was a relief to find out that’s all it was.
Here’s a 1:10.1 lap:
Here’s the vid I posted in the supersprint thread where I am being hunted down by the time-attack charade which was the quickest car of the day.
So, I think I might give the mk1 a bit of a rest for a while. Despite hardly ever updating here, I am almost constantly tweaking and improving this car. But for now, I need a good break from it

Have never done a track day with a car or a motorbike, but just going to give some constructive criticism. If you turn half a second later and keep it as smooth as possible instead of jolting side to side to keep it on the track I reckon you might be able to hit 1.09 or even 1.08
Like I said never done it before and I think you did really well. Just something to think about for next time.

Great results pal. A true testament to your build quality , and beautifully welded manifold, that it survived the days punishment and performed so well.
Great work , keep flying the mk1 flag.

You wouldn't believe how quick this Mk1 is from the outside. In car cameras don't really give the right impression of speed. Torque steer and sliding under brakes is the main reason for the squirrelly looking video. Half a second later braking would have you off the track without a doubt.

Not braking half a second later, just turn a little later and try pick a line and stick to it. Thats all I am trying to get to. But like I said, your times are fast and would have loved to see it live. But just something to think about.

Thanks h100vw.
Mk1@4motion, what you are seeing jumping around in the 1st video is the forward facing camera itself, it’s not the car. The camera was shaking a lot. As for when to turn in, if you don’t know the track, how could you possibly know the lines? Now I posted these videos to show my car doing what I built it for. If you want to critique my driving, at least look at the back camera view, that camera is not bouncing around (and funnily enough, neither is the car!). Better still, post up some footage of you cracking 1:10 in your mk1, showcasing this ultra-late-apex-super-steady driving technique you speak of. Now that actually would be constructive. Just something to think about..

So at the last track day I discovered that my brakes are getting towards their limit. They definitely got too hot, and I had to get the front discs machined as they were glazed. So it was time to set up some ducting to get a bit of air-flow into the front brakes.
After some investigation it seems the go is to get air flow right into the inside hub part of the rotor as much as possible. The vented rotor acts like an air pump, pumping from the centre and outwards through the vanes of the rotor, so you want to get as much fresh air in there as possible. Seeing as though our calipers are at the front of the wheel hub there isn't much room left, and after my first attempt of routing piping to the rear section of the brake backing plate failed, I was forced to re-try going into the front, just above the calipers. There is just so much movement going on in this area, suspension articulation, struts turning, sway bars, brake lines, wheels swinging, you just cannot get past all of this with decent sized ducting. I was forced to route to the front, so I went from 3" down to 2.5" ducting to suit the biggest pipe I could get into the area.
Here is a modded backing plate. The larger 3" hole was my first attempt. I decided to keep the hole there as this will help vent some of the heat from the inside face of the disc, which tends to get hotter than the outside which gets more airflow through the wheel. http://www.vwwatercooled.com.au/foru...106155a7-1.jpg
After some test drives, no rubbing at all! If you look closely though you can spot the orange ducting in the wheel well, and in some light it stands out. That should get a few observant spotters wondering what the hell is going on in there :) http://www.vwwatercooled.com.au/foru...9f8ce8d3-1.jpg

I'll let you know shortly as I plan to go down to wakefield in the next couple of weeks. One of the better DIYs guides in my searches was actually a Honda S2000 guy who set it up and tracks his car a lot. He reckoned it prolonged pad/rotor life, and performed noticeably better. It can be the difference between keeping your pads in their optimal heat range, or getting out of that range. My current wilwood pads drop off torque at about 370-400C. I have no idea how hot I am getting them, but it must be more. Mind you last time my car was double entered so it had less time to cool. You can get a paint that you put on the edge of the disc which discolours according to max heat which would be useful.
