Not biased at all but you should get the twin screw! If you're only wanting like 425rwhp then I would think you would like the twin screw over the centri. I made over 450 with just 39lb injectors. Sure the fuel system may have been maxed out, i dont really know exactly what the duty cycle was but it worked for 2 yrs so don't worry about a damn BAP unless you absolutely have to! Just my opinion on blowers, I'm sure there will be someone to disagree with me but then again I've never driven a centri car so maybe I am biased haha! Either way you'll be happy as hell to have some FI they all make good power and its all fun!!
