hat and port injection

Help, going from 8-71 with hat injection to 14-71 with hat and port injection, plus 2 @ back of rotors. 565 ci. 14-71 bds air lock, enderle bird catcher, 110 pump, brodic 2x plus heads, 800 lift oddys cam. 11.8-1 comp. 30% od. What is a good starting point for hat, port, and extra 2 nozzles to cool rotors? Thanks

 

Good starting point will be getting a bigger fuel pump.

I have about the identical combination, cept 10.4:1 compression.

I just plugged all my nozzles into the chart with fuel pump numbers It said that a 110 was better?
Or I need a .325 mj with a 990. That aint right. The chart doesn't spec pump vol at what pressure head. Is 4000 rpm right? HALP!

 

If I understand you correctly , you are running a BDS blower and a Jim ODDY's camshaft. Well my sincere recomendation is to get your system setup direct from billy at Oddy's because the money 500-800 that you will spend on your first setup will not compare to the headackes and lost time by not getting a good flower system .

Plus oddy's was always in contact with BDS back in all blower projects.

 

you have to know how much fuel your pump pumps @ what R.P.M., plus you might have to use a pump sizer if you use the 990 pump, but like JP said you really should send the system out to be flowed for that new combo or you might be playing with it for some time, the chart is just for getting you close, read the disclaimer and the instructions,because it's complicated. the fuel guys do it all the time, it's like what you do for a living some one else would find it hard to do for a wile.
