Subject: Re: V12 4 carburetter: SU D4s v D5s
Hi Laurence,
If your car has 4 x D5s then it will work fine, the engine will work on D4s or D5s just as easily as SUs are mirraculous at addapting themselves and let's face it, a 4.5 litre V12 can easily cope with 4 smallish carbs like that, just look at a 1960s 3 litre v12 Ferarri with 4 dual Webers. it has no more power tha a well tuned Lagonda and won't rev any higher either in std form than a 'Mell' tuned V12
Rest easy, it will work a treat.
I would suggest going to a well established rolling road with an experienced operator and someone equipped with needles etc and spend a day getting it working really well, it can be some of the wisest money you will ever spend.
Best regards,
Julian
