looking into a vf22 subaru turbo looking for ome good power any idea what the spool up time on such a turbo would be ?head is ported and stuff can rev the car into 8500rpms with new springs
depands from many factors mate! i managed to see a slightly better spool and lower rpm kick by just fitting a good boost controller and using gain! good tune will help it too
well ive a choice of two turbos a vf35 or a vf22 so a friend of mine wants the one that i dont use ,so i think the vf22 will suit with a nice set of cams ,whats the max bhp from the vf35
