I’m in for this, just getting going with a Shorrock install on an A series That's a rare beast! what condition is the supercharger in? Well... it spins freely, and I’m assured it’s good. The chap I bought it from used it as a spare for his speedway bike... seems to have all the mini manifolds so I’m sorting out mounting and an inlet manifold.

So I want to simplify the wiring and nonsense in the engine bay. Adjustable ignition will help with the supercharger install, so I'm going with an early suggestion of going with NoDiz. That needs a trigger wheel for a crank position sensor. If I were going this again, I'd get a trigger wheel cut to spec, as this was tricky. Plan A was a generic trigger wheel, and part it off in the lathe to get a 145mm diameter hole in the centre, Boudica would have been proud of this, it even looked dangerous to me, so I hung a big curtain, and stood well back. But my little lathe struggled to part off 5mm steel. So before that got flung into orbit I tried something else. With a good groove to act as a marker, I thought a jigsaw might work well - it didn't I didn't have a 145mm holesaw, and nothing close was available easily - plan C was therefore a non-starter. Plan D was my newly purchased Lidl plasma cutter. I tried a smaller hole using a plywood template to get my eye, and settings dialed in. Just as well I had a practice, as the first attempt was a pigs ear. But the second attempt would clean up tidy enough. Cleaned up and tacked onto the back of the bottom pulley. I'll add more weld later when I'm 100% it will work. Here it is in place, with the engine set to TDC I believe NoDiz needs the missing tooth on the trigger wheel 90 before TDC. There are a couple of handy looking bolts on the engine, that look ideal to take a sensor bracket. That should be an easy fab job. Then I can spin the engine over, and check it does its job. Thanks for looking

Do you need to worry about that pulley being out of balance?

I mean, it wasn't that I didn't have faith in your ability to clean up the plasma cut edge... But Looks like there's a few handy bolts to mount a sensor bracket on.

The stainless mandrel bends finally turned up. So lets mock up the inlet manifold Some of the runs will be shortened to "tighten" it all up a little, but I didn't want to start cutting stuff to size just yet. Here it is roughly suspended in place. And a couple of other views Do you think that will work okay ? Well once the racer tape is replaced by welds, and the cardboard by stainless The boss on the top is for a Shorrock style relief valve, which I'll probably get set to about 14PSI I'll also need a barb for a pressure gauge, but that is easy. Am I full steam ahead with this design

Oh and eBay had a 5% off coupon today. So I've ordered the NoDiz kit and the blow-off valve. Hopefully that should be the last of the big ticket spending.

I can't help with anything on this as superchargers are like black magic to me haha. I'm a turbo person much simpler lol.i do have a mate who is in the early stages of getting stuff together to supercharge his V8 so some of this may well be interesting to him. Especially with the pulleys and the maths. Il point him this way.
My question is what are the Chinese lathes like. Do you have any links to were to get them from. I'm not expecting commercial quality but are they"good enough" for home projects
Cheers

That dump valve - won't it be dumping rather combustible fuel/ air mix into a hot area?
Can you pipe it onto the floor maybe?

I like mine, but I spoiled it putting on a cheap toolpost - that has now broken, so I'm going back to the original. I'm pushing mine too hard with 6-7" pieces of steel, but for smaller stuff or softer materials, it isn't bad. I didn't want a project lathe, and fully variable speed and working straight of a 13Amp plug made it a winner for me. I got mine via these people Amadeal but on their eBay shop as I had a voucher and a bunch of Nectar points to cash in. Hope it helps

Hopefully it'll never vent... but if it does...... Putting it where I have, it might vent out of the louvres I've put in the bonnet if I'm lucky. The whole passenger side of the engine is iffy due to the exhaust manifold. If I routed it to the ground, would I not be making a trap for petrol to condense and drain into Tricky one

Is a dump valve required? Isn't the carb/throttle on the supercharger inlet?

Yeah I saw those one eBay wondered if it was the same ones.. I do a bit with models/RC stuff too and had seen them before. I'm not expecting to be turning down foot thick billet tool steel with it. It was more just for little jobs (I've had to modify an alternator pulley for my v8 and this would have been perfect).. Il keep an eye open for the special offers on eBay and see what pops up. Cheers and good luck with the project!

It’s not a dump valve per se, it’s a backfire control valve. Presumably to vent the pressure from the inlet manifold when its all gone south. I’m not sure you can set the pressure on them? I assume you bought it from Oldspeed?

Guess it being calibrated to the boost makes sense. 7psi spiking on gear shift, will be quite different to 11psi spiking

Not too much progress on this, as that annoying thing called work got in the way. The NoDiz turned up, and has been stashed away safely. But I found a little time to make the crank sensor bracket. Take a hunk of old box, and cut out a section. Bolt on the roughly hewn bracket and use a pilot drill to check the placement. I cut the bracket to a more appealing shape, and added some holes for detail. To get the clearance close, I welded on a boss. Slotted holes allow some fine adjustment. Bolted in place - looks like it will do the job Thanks for looking
