How would CTR cams work with FI?

I will be running ITR cams, which are either the same or extremely similar to CTR cams depending on the year of CTR cams....

so very good.

NA cams and FI cams are designed differently with lift and duration. A NA cam will have high lift with a duration that over laps so both valves are slightly opens at the same time briefly to cause a suction affect on the intake when exhaust gases are being pushed out which makes for the power gain. In FI setup you want high lift with a short duration so there is little or no overlap so the boost does not just flow in and out before it is even compressed in the chamber. IMO i would not use ITR cams or CTR cams in a FI setup the best stock cam shaft for FI setups are GSR cams AKA poor man's crower... lol. hope this info helps.

ITR/CTR cams are defintely the way to go. I can find you plenty of 500+ whp hondas with either GSR or ITR/CTR cams.
