Hi, I recently bought a Blackbird engined Fisher Fury. Having read loads about The Blackbird's tendency to go bang in BECs I'm looking to install an Accusump (it already has a baffled sump). I would love to hear from anyone who has already done this.

Also the clutch is almost unusable (either on or off) any available advice on this topic would also be very gratefully received.

Thanks in advance

Leon

Is it red and on a Y plate?

Hi
blackbirds can throw up a few issues and an accusump isnt a bad idea, plumbed direct into the main oil gallery is quite a simple install on the bird, you would nee a 4pint accusump, the electric epc valve which stops the accusump refilling until engine oil pressure is reinstated , the sump mounts, hosing and afew swivel fittings and adaptors, we keep most of this in stock, give me a bell on 01449 736633 if you would like more info

As Andy says above, easy install and use the parts he recommends, ran a Bird for two years on a accusump with no oiling problems,

Ive just plumbed mine into a busa, similar set up if you want pics ?

Hi Also did a bird but with a manual valve no issues, plumbed as andy said,

clutch wise i used the std blackbird master cylinder and was easy to use on my dax i have altered the ratio slightly and is more car like now,

i use a 0625 m/c

good luck,

also overfilled oil level by 5-10%

Hi Jon, some pics of your Accusump installation would be really useful.

Thanks,

Leon

Hi pic of mine for you.

follow the blue pipe you will see it plumbs into the oil gallery at the front of the engine,

or as on a bike where your right foot would be,

remove the bolt and may need to be tapped to accept fitting,
cheers

Regarding the clutch issue.

I have used a rear brake master cylinder (SV650 I think) although they are all pretty much the same.

Specification for this seems to be 1/2inch bore, and 1/2stroke (maybe slightly different but the two that I had were both the same). You can also change the pedal ratio. You need to be careful not to overdo all this and so not pump enough volume to disengage the clutch!

The pedal will be very light whatever you do, which doesn't help. Some people add additional springs (I haven't).

The nature of these wet clutches is that they are a bit ferocious, but it should be possible to get a nice working configuration. Mine is quite nice, although hill starts still require concentration or bags of revs.

All mine old car had was the original BB M/C extended back so it cleared the prop adaptor.

Its fierce at first do you soon get used to it.

My current car is nicer but I think some of that is because its FI rather than carb'ed. If I'm smooth I can pull off on the flat just raising the clutch (i.e. no throttle). Couldn't do that with the blackbird!
