Blackbird Oil starvation issues?
Hi
This is my 1st post on here so Hello all
Anyway i have just purchased a Formula 27 kit car with a super blackbird engine fitted and unfortunatly have come across some of the posts on here
mentioning about the oil starvation issues that the blackbird engines has when mounted inline. I am wanting to track the car so ideally would like to
find a way to get round it.
My first question is do the super blackbird engines have these same issues...
People have mentioned dry sump setups and a system called accusumps but does any companies sell these kits for the blackbirds or offer fitting.
I do have a spare black bird engine and was wondering if any internal work could be done easily also.
Thanks for your time
Ryan

Cant tell you anything about bird engines but an Accusump is an efficient way to go. Buy one with the electric switch. got mine off ebay in the states
half price brand new from Canton. Good rate still and if they mistakenly mark the customs form 'used parts' you don't have to pay
duty !

Thanks for your reply
Has anyone got an info on how an accusump kit is fitted to a Bird engine?
Also i read that it was better to go for the manual valve type as the electric valves can become a restriction?

Accusump system
We Have fitted a number of accusump systems to various motors including my own F1 sidecar. The issue you refer to re electric versus manual valve can
be an problem. The way the electric valve is designed means it is much much slower for the oil to refill the accusump so the issue you can get is
having taken one fast corner and the accusump having done its job and fed oil into the engine, you then enter another bend and the accusump has not
refilled and cannot then protect the motor during this period of surge. I checked this with the guys at Canton and they confirmed our suspicions and
we went manual. To give you some idea of the delay I watched the accusump cut in around Gerards at Mallory and with the electric valve it had not
recovered for the brakes at the hairpin, changed to manual and sump was reinstated to full pressure half way down the straight.
As for install you need to mount the sump longitudinally with air guage end raised slighly so any air in the accusump rises up behind the oil charge,
so you push oil not air into the motor. It is best to plumb it directly into the end of the main oil gallery if possible but failing that you would
need to t into the oil cooler return line. If you need any help give me a call on 01449 736633

Hi Andy
Thanks for your reply
Im looking to install it where the oil pressure switch is fitted as many members have recommended this place when i have searched on this issue.
Do you offer kits to be able to fit the accusump kits. Ie the oil fittings etc or do you know what the thread sizes is where the pressure switch is
located so i can get some made up?
