Armed with Gtech PRo, this week I am going to run some 0-60/ quarter mile tests with the Powercap (Mantzel version) & then SFI box. Will also try both with/without intake trumpet in upper airbox.
To get a better idea of how either affects performance, I also want to log 'rolling' performance. i.e. time 3 - 6.8krevs in third.
What are the most reliable / indicative rolling measurements of respective merits?
