Ok so I'm probably gonna get burned here but I got a 3 inch pod and elbow bend so why not? B series have been running 3 inch ubp's since god knows when and making up to 350rwkw's with good response, I'm after as quick as possible spool and personally I think a 4 inch may be overkill for the small FG Turbo at this power level. I think a 3 inch intake will flow more then enough to make 320 and with less lag then a 4 inch. Also I just want to try something different from the norm. Genuine interest in the subject would be much appreciated.
