Yes the 100 would be good for sure and those Hogan intakes are some quality stuff . If you get a chance to read my site, there is more detail there, but I put that entire extrude honed intake system/runners/plenum on my car many years ago, nothing is different on my car in over 5 years except the clutch I did about 1 1/2 ago. The intake I have was actually put together by 8388 for another project, and I bought it and used in on my B2K as it is a factory intake, just extrude honned pretty big. Its definatly as good of intake as you are going to get and works very well on the callaway without redesigning the car.. Redesigning is something I refuse to do.
That dual injector setup would be nice, but what are you going to use to fire the second group????? The microfuller could actually be rigged to do it, but its not even going to be batch fire and will just be an on-off relay on those secondary injectors.... Sounds like a complete aftermarket computer would be needed at that point..... With that, you would have a life time commitment of dialing, tuning, experinmenting, to get it to run 1/2 way as good as it does with the factory..... You would probably save some cash too by investing 30,000 on a dyno for your garage, as its going to take that much time, testing/tuning to get it right. The factory is not right, but its good and I dont see why you could not get 600HP out of a callaway TO THE WHEELS using the entire factory computer with a 1/2 way decent big tube set up, or the rare callaway 100, a little more boost and the fuel to compensate for it...
If you want more fuel.... Raise the FP on your callaway to the mid 40's at 0/HG... It works just fine for me in 5 years of racing the car.....If that is not enough for your taste... Go to 30 LB injectors in place of the stock... It will allow quite a bit with added FP.... If that s not enough, use a rising rate FP regulator allowing low pressure on 30 and even larger injectors when the car is out of boost.... The Car-Tech can go from 38-100PSI if needed and some old-style injectors wont lock even at that pressure. The callaway already had the good Bosch fuel pump in it. With all these options running factory stuff, you can definatly get some major power without messing with stuff like that hogan, or aftermarket computers..... If none of this is not enough for you, Just Build a race car at this point from some cheap corvette...... Save the callaways from that life!.....
