I spoke to SHOShop and they are making a new kit for the SVT. the guy i spoke with wasnt sure of specifics he said i had to speak to the manager. but its supposed to be about 6 lbs of preasure and 80 hp increase. its made by windjammer. (i tried to search for it on the net but found nothing on that brand) its about 3,300 bucks and DIY install. i wish i knew more about it. if any of you guys have any facts on this please post it. oh yeah and he wasnt sure if it was for the returnless fuel system. but im pretty sure that unlike the centrifugal vortech, this is going to be a positive displacement supercharger.
