making the jump to a twin screw on my 03 cobra. Will either be running a 2.2 kenne bell or 2.3 whipple. My question is, which fuel pumps should I buy to run this set up. dual svt focus pumps? dual gt supercar pumps? Maybe just a kenne bell boost a pump???? Also I heard that if you run the supercar pumps you need more voltage to run them?
