Ok lets break it down, you are comparing 8PSI (SC) v. 13PSI (TT), that is just retarded sorry. Second, the 13PSI would be the top end of the Stage I TT kit, which by the looks of it is the idea of that dyno, race fuel plus max PSI.
45 horse? Where did you get this number? You honestly are just throwing out numbers with nothing behind them. Great you found some dyno graphs but no baseline of each of those cars. Did the car run 300whp before the kit or did it run 240whp?
I understand you wanting a NA engine which has great engine response, but honestly you seem to be missing many things when it comes to research on the VQ37 SC & TT kits. And where are people getting 450whp from SC? Search and you would have found this:
