I remember a while ago, someone i thought had a hybrid BD2/ DB4, the DB4 pumps were rated at 40 BHP per cyl. That might be the way to go if the DB2 can not move enough fuel on its own.
I think it is possible to see 400 HP from these engines with the right amount of work. A BD2 injection pump was rated from the factory at 25 HP / Cyl, about 200 HP. Sounds like Mel could get you the fuel if you can support the boost levels needed. What kind of twin turbo setup are you thinking about?
400hp at the wheels is goin to require upwards of 160cc/1000strokes out of the pump. I bet the DB2 can flow that, but it will require a lot of work.
These idi motors came from a clean sheet of paper. They were never a gasser. Look at what I have done to my motor. All the balancing and align boreing was done to cut down on internal drag. Look at any rod or main bearing when they come out. See some wear on either side... Thats a aligmnent issue so it wears to one side. Thats drag imposed on the motor. The cylinders need to be bored true to the crank. Or the pistons will drag on the bores. Deck the block. All V8 blocks are twisted. So truing this up creates a better volume in each cylinder. CC the precups too. The cup chambers in the heads are really ruff cut. Make them all the same size by the CC method. Barnett Performance offers 2 differant stroker motors. They have a web site... Give them a call and see what they can do for you. Russ (Typ4) does a good job with the cams. He is also as great a guy as Mel is to work with. Read the Hall of Shame for the crap pots some of us have dealt with. You wont buy with anyone listed on there that a given. Twin turbos... Sounds like you really want something.. There is plenty of help offered here free so use it. Many like me have already made mistakes for you so learn from us... Its no shame.... Really.....
