Hi There A buddy and I decided to design/create or own CAI for the RunX RSi(Sportivo) as the cost to import a TRD/AEM CAi is just damn expensive ($??? X 6 = about R3000+). We had a system which gave us an incredible increase from 1000rpm to 6000rpm after that the ride is dead, zero lift. Well not really zero lift the car goes into lift but 1 can feel a big power drop. We have played around and I currently have a TRD CAI type setup in my ride, nice tone and a improvement in power in the mid rev range. But we have 1 problem, when racing you only feel this power in 1st gear after that one keeps the revs in the 6000rpm+ range. What I am looking for is an increase in power from 4500rpm onwards. Has anyone played around with CAI`s? Is this possible? How? Please let me know, Thanks.
