Don't they normally leak from the cover to back plate not from the back plate to block. Looks really nice to me. Seems OK value, but not on my shopping list to a long time yet. http://www.twin-turbo.co.uk

As Ben says, a wobbly steel backplate is the cause of leaks, a rigid alloy backplate won't leak, the o ring on the cover plate won't leak. There is a built in position for a trigger wheel. If Carling made Mini engines

There's just not enough distance between the block and a duplex to get an O ring seal inbetween.

You could contacted DSN and see if they'd machine a boss for the cam sensor into one? https://www.facebook.com/pages/Fusion-Fabri..._homepage_panel

Aksherley, I've just checked out my alloy duplex and although it has stainless screws, the screw seats on the front are ferrous. So the cam sensor will have to go in the back. I'll just change one of the screws for a steel one.

Why use a tensioner with that Kent timing kit that has had the sprocket sizes designed to do away with chain slack? I seriously doubt it! |

I simply don't believe any timing chain should be used without a tensioner, for accuracy and long life to the chain and sprockets - simple as that. This blocks been line bored as well - moving the two gears closer together. I'd like to do a variable cam timing kit for a Min but this isn't how I'd choose to do it!

Dsn's machining looks superb do they do one offs?

Nice... They looked good at bingley I run a supercharger and I don't care the TB is on the wrong side.

It would be interesting to see the weight difference between one of these and a standard cover with a td back/front plate. On 11th Feb, 2015 robert said:

I don't think it would have been a case of not wanting to know. If it came across that way, I apologise on Dave's behalf. The biggest issue with one-off's is cost. Most people cough and splutter at the setup charge. Simple items can incur a setup of £200. Obviously, more complex items can be much higher. Hope that clarifies it a bit. Steve

The 'td' back plate is a lightweight alloy one. probably at least 1/2 kg lighet than the standard one. Fastest 998 mini in the world? 13.05 1/4 mile 106mph

£200 for set up? how much do you charge per hour for machining? one day boost will be mine!

£200 for set up? how much do you charge per hour for machining? I obviously didn't explain it very well. The set-up relates to CAD/CAM time (getting the design on to the PC and defining tool paths, etc), plus manufacturing of tooling where necessary. Obviously, if you can supply a 3d model file that we can read, it would reduce the cost to some extent. But the CAM part would still need to be carried out and, depending on the product, tooling might need making to hold the piece while machining. For simpler 'one-off' items, it might be more appropriate to have it made on a 'manual' mill rather than CNC. This would increase machining time, but reduce 'up front' costs. CNC machining is more appropriate for production runs rather than one-off's. Steve

I understand what has to be done to get a cnc set up going, I'm a programmer/setter. It just seemed like a random amount most places quote per hour. one day boost will be mine!

It's difficult to know how to explain when we don't know how much you know!! If that makes sense! Teaching granny to suck eggs, etc! The figure is based purely on experience with previous items and is only an example. We tend to quote set-up fee as one figure, plus cost per item thereafter. We aren't a machine shop, it's only there because we wanted to manufacture in-house. So it's distinctly possible we do it differently to everyone else 
As an aside, we don't programme on the mills. It's all done in OneCNC and transferred. Programming directly looks far too complicated.... we'll leave that to you experts! Steve
