Finally got this mocked up this morning after several weeks of stealing an hour here and there. The tubes replace the SUs. Just need to do some welding.

I've been at this job for the last 2 weeks and what a pain... I bought the hydro handbrake last year but not the lines that were available with the kit. I should have sprung for the lines I now know. So I've been slogging it out trying to get the brake lines in and it's taken me three goes to the get the fittings and ends right. I had it all in yesterday and realized I had it hooked up the wrong way around. So back to the brake shop again today. Thankfully, the local brake shop was just awesome. Never angry or sick of me. Just patient and helpful. I gave him a 6 pack today to say thankyou. 🙂

 

So now it's finished and just as well. Motorkhana on Saturday!

Had a good day out today at my club motorkhana...

Whilst having a good time, I realized that I am still not used to driving the car in anger, let alone on top of how to get it to go faster. I was hoping to get it to drift more easily but really failed. The hydro handbrake did help a lot, but I wasn't really on top of when to use that either. At the end of the video, you'll see me "testing the diff" in the distance. Basically, I wanted to see whether the car was up to doing proper donuts or not. The good news is it is. I'm just not succeeding at the moment. I was also pretty tired and making lots of silly mistakes today, so that didn't help. I guess I've had 2 decades of driving aircooled VWs in khanas and the front engine/rear drive datto is a big change from that. I had my tyres setup with 26/40 PSI front to rear but that wasn't enough. The front wheels were washing out while the 2 way LSD just gripped harder. I'm starting to think that some sway bars might be needed to help me a little.

 

I'd be keen to hear people's thoughts on this.

More adventures today.

 

1. I'm still trying to sort out the rear brake circuit with the hydraulic handbrake in it. Somehow, the handle is pressurized when I push the pedal.

 

2. The float in the front SU carb sustained a leak and I had fuel pouring out of the breather. Stew Wilkins set me straight, but now the car has a hesitation. Thoughts on this?

After procrastinating for months, I've finally done it. Ie. drilled big holes in a perfectly good manifold. Of course, I wasn't confident to get it all right just by eye, so I made up a jig from angle iron. It holds the injector mounts in position with M10 bolts. The plan is to epoxy them in with JB weld. I'll probably do the two outer ones first, then the two inner. I still will need to trim them back afterwards. I have some gaps around the injector bungs, but I figure the JB weld should fill them up well enough. I just want to experiment with it one before I actually glue them in place.

Noice!  How much angle you put on those bungs?

I'd say about 45deg. I know it won't be as good as a factory port injected setup, but it's about the same as most of aftermarket weber TBs on offer.

My question was for curiosity not judgment of what you chose.  I'm very much in support of what you are doing here. 

 

Have you considered brazing as opposed to jb weld?

I hadn't, because I don't have the equipment. TBH, I think I'll need the JB to seal up the gaps properly.

Well, I finally have an inlet manifold with injector bungs. I used JB weld to stick them in and I have to say, I'm pretty impressed. One issue I did have was getting the epoxy to cure properly in cold weather atm. In the end, I had to resort to putting on our wood stove to get the temp up. Having done that, the epoxy cured really well.

Having got that done, I needed to trim the excess off the injector bosses. I fiddled around with the dremel for a bit and then got out the big guns. Ie. my wood router. There were a few little mistakes with it nicking the manifold, but it's kinda hard to see down the ports with the router in the way. In the end, I'm pretty happy with the outcome. I've blended the mounts as much as I cared and then wire-brushed with the dremel. Should be good.

Been a long, but ultimately productive day, although not quite as I'd imagined. My daughter went into hospital for a big test today (which went really well) and I was left to my own devices. It's been the coldest day in Sydney in recorded history here (cold for Australia) so it took me a bit to get going, but ended up at Barry's place using his drill press (because mine is beyond awful).

I probably spent two hours measuring and marking up the fuel rail before I actually got there. I was determined to get it right. Of course the drills wandered anyway. As it happened, we were short of a 13.5mm drill for the injectors. The largest we had was 1/2".

And then my boys were harassing me to pick them up. Something about it being cold and wet coz it was raining, -15degF and the school forces them to wear shorts. 😄 Seriously, the school makes them wear shorts. 😨 I didn't, but I did let them into the house... having found out that they had keys anyway! 

 

Barry suggested I check out the local tool shop and what a find that was. They had all manner of stuff and sold me a drill bit about half the price the big hardware chain does. They also helped me to find what size tap I needed for the ends of the fuel rail AND gave me a free 3/8 BCP taper plug to try out. 

 

I was ready to drill the rest of the holes when I was told I was on dinner duties. Then my 12yo son told me some creep pulled up next him invited him into his car on the way to the bus stop this morning. I was horrified and called the cops. They've been up to interview him. I'll be calling the school tomorrow and the cops will be sniffing around to try and find this guy.

So, after all that, I managed to get back into the garage and have another go. I made a guide plate for the drill bit so it could wander. I meant to put it in the drill press, but that wasn't gonna work for various reasons. I ended up using my cordless drill. Sure, it's not great, but the holes will still be super tight on the o-rings, so it should be find. I've also tapped the ends of the rail for 3/8" NPT too. I'm feeling excited, but I still need to make up some retaining brackets.

P.s. I'm gonna keep the offcut for another EFI idea. 😉
