This is more of a product question regarding the JTSVP throttle body. My current TB is a little rough looking on the outside so I was considering replacing it since I'm taking off to clean it. Looking around it seems that there are two aftermarket options, the JTSVP and the BBK. My question actually lies in why are both using dual circular ports/butterflies vs using a single oval opening? My extremely rough math says that a single oval port would be be about 13% larger than a pair of 68mm ports. That being said, why did you go with twin ports rather than one big ellipse? Is it a manufacturablity item or is there something more?
