Nick,

The main reason I decided against K&N with a stub stack was cost - about £400 to do the car.

The performance of a K&N is slightly better than a new OEM paper filter that costs £8, so the £120 per K&N is just not worth it IMO and figured it can't be that difficult to make sub stacks that cost £80 each.

But the cold casting - esp the high temp versions might be just wh...

Potterycrafts, formerly Alec Tiranti, seem to have started doing many of the things again such as the mould making and casting stuff and the resins and white metals. I had a look a few years ago not long after they changed and all that stuff had gone.

The one you've pictured isn't a traditional syphon type flush. It effectively just opens a sluice and the water floods out. It's highly unlikely it would fit to your existing unit. It would need to be fitted in its entirety, necessitating removal of the cistern.

There's a slim chance that the manufacturer of your existing unit makes a dual-flush version, which might pos...

On my 1275 ( which still doesn't have a buyer!) I changed from twin SU s to a single HIF44. I had a K&N for the twins and they are expensive, so I made a fresh backplate to match the HIF to the long K&N and fitted a bell mouth inside that.

I glued mine to the backplate with 2K metallic resin, such as JB Weld. My logic is that the H1 is so small that anything to smooth the intake must help. I didn't go to the trouble of making a mould, I just sanded it by eye and checked with a profile gauge.

Thanks Trev,
think I've found a similar one in Toolstation which has the plastic chrome handle I think you may be referring to.
If it the same one, could you just unscrew the old valve and fit the new one or did you have to undo the cistern/pan fitting too?

Bill, check PM on MG exp. board. George

An appropriate example of cold casting in resin/bronze.

You may not find Tiranti the same company they used to be as they were taken over a few years ago and are now Potterycrafts , they certainly don't do some of the things I used to get from them.
