    I would say when you go bigger SC wheel or Aftermarket IC

    Agreed, but it also depends on the SC wheel and intake little bit. If you go with a S2 SC then the 14/19 will be fine. If you go to the green wheel and stick with the stock intake or 3" intake with stock IC you could probably get away with the 14/19 with a little more added to the trailing edge. I would imagine you would have a pretty mean holeshot with that leading edge, but I haven't heard much. Now if you go green wheel or higher with a rear intake I would go with the 15/20. Anytime you go with an AM IC you will need the 15/20.

    If I was you, I would do it when you get a bigger SC wheel or aftermarket IC. Thats what I would do.

    i am running the stage 2 wheel,always colder weather here compare to most of you guys,runing 73.9 without the riva stg 2 wheel,costant 8100 rpms all day long even 8150 rpms from time to time.
    i rather not get a 15/20 and have to take off some of the trailing edge.
    i have noticed most of you guys in your beatiful hot countries with my aproximate set up are only running 72,73 mph.
    i am assuming i still need a external intercooler before i go this route (15/20)

    thanks

    i have a tage 2 rxp and the 15/ 20 is too steep for the vortech wheel it will only spin it 7500 rpm it seems to axcellerate better than stock but it is killing my top end ...the green wheel is a couple pounds more boost that may be enough dont waist your money on the riva vortech wheel...just want a wheel go green @450 a little better riva housing and wheel still 10 psi but more volume ... @ $800 neither need ecu change maybe 42# injectors for the riva w stock ecu add 200 for injectors ... or go all out and get the rude charger 2000 +++ecu +injectors+ valve train then youll be flyin on a lighter wallet
