Supercharging 13B NA 9-12lbs street

I've been trying to figure out how to do the injectors, I'm going with a megasquirt, I had a parts car, which i pulled the injectors off of, i am going to be running about 330RWHP ~ 11/12lbs. I have the spare red top 450cc's, could I put these to use as opposed to upgrading the 4 injectors in there. For example, instead of 4 x 900's just have 8x 450's. Anyone got any ideas?

I've been trying to figure out what needs to be done for fuel, thats the only thing i haven't done. I've plotted the compressor map with different size pulleys, matched the airflow for a Vortech V-2 Supercharger. I need a solution and this is the one part I don't know what to do.

It's going to be a lot more work to use 8 injectors, ie custom manifold. You would be a lot better off just going with 4 larger injectors.

your running 11 pounds of boost off a vortech supercharger and your only going to get 330 hp i think your calculations are off a bit

'only going to get'? How about you won't even get? It's not very efficient, especially in the range of a rotary, your best bet would be to bleed off an ammount to shift the efficiency range up (although it's still not very good)
