I got the nose mount cut out and all the holes lined up. 

 

 

 

Even better it fits on the engine. 

 

I started on a template for the mount of the other end as well.

Very nice! Quality work there, I love the attention to detail.

I mocked up the pump side of the supercharger mount this evening. It'll use the two bolt holes for the engine steady and possibly another leg down the old dissy mount on the block. 

 

Everything's marked out and ready to cut tomorrow, I'm definitely considering remaking the mounts in alloy once I've got it all working.

I cut everything out and fitted the locating dowels from the old water pump drive into the new mounting plate. 

 

The first section of bracket from the block was bent and then twisted to line up with the plate on the SC. 

 

I got everything else lined up and tacked together, this wont be flexing. 

 

And now it's back on the block again and the SC is free standing.

What SC is that buddy?

[Tupers]

It's an Eaton M45 from the first generation of supercharger BMW MINI Coopers. It's a bit of a lump but it should get the job done.

Excellent fabrication as ever.

Thanks Jagman I do try. 

 

 

I pulled the engine out this evening to get a grasp on how to tension the drive belt for everything. I originally intended on using the tensioner from an MPI mini but the bracketry was too bulky so I stole it's pulley and decided to make my own mount. 

 

Plotting all the pickup points for this was a pain but using the plumb line as my starting point made measuring to the bolts marked in silver much easier. 

 

After a few attempts I came up with this. 

 

The adjuster will sit on the outside and been nice and easy to get to and the mounting bolts will run in sleeves that will be gusseted to the mount.

So I stumbled across a Specialist Components EFI kit that someone was selling on after running for a year and decided to snap it up. 

 

It needs pulling apart and cleaning but that's OK as I'm considering anodising it all in gold anyway. 

 

I had to bolt it up just to get a look at the complete set-up. I guess I'll have to start designing a new plenum to suit the throttle body now.

Starting to look really awesome now, getting an idea of how it'll be in the end.

[bpirie1000]

What sort of bhs you expecting?

[SAL 821X]

bhp? lots I imagine looking at the thing. Its a beast for sure! I can almost hear the wine! 

[benjy_18]

Supercharged engines don't give massive bhp, probly around 120 for a good spec

Knowing Chris I'm sure he would be aiming for something sensible!

[Tupers]

Thanks for the comments guys. I'm really not sure on power, Ben's probably fairly close although I'm prioritising torque over maximum BHP. 

 

My brother came down over the week end and we got talking about the engine which led to me deciding to switch from a 1098 to a 1275. It seemed silly to be spending all this time and money on an engine that would have fairly limited potential for future upgrades and long term strength. 

 

Irritatingly the 1098 and 1275 blocks are just different enough that and I had to spend most of this evening reworking every bracket I'd already done to make it all fit. On the plus side I will now be able to build a much stronger engine to make the most of all this work. 

So this is what it looks like now, barely any different but it'll be worth it down the line.

That engine is going to be a beast, and a saxo killer for sure....
