I dyno'd my car today. We did three pulls and the end results are SuperTrapps with 15 disks gave the most h.p., Magna Flow's were second and SuperTrapps with no disks was the weakest combo. Here's the numbers:
SuperTrapps w/ 15 disks: 196.5 h.p. @ 6600rpm Torque 165.4 @ 5200rpm Magna Flows: 188.6 h.p. @ 6450 rpm Torque 165.8 @ 5200 rpm SuperTrapps w/ no disks: 186.8 h.p. @ 6600 rpm Torque 162.7 @ 5250 rpm Air fuel ratio was about 14.7:1 with the SuperTrapps. Is this too lean? I screwed up and forgot to put some racing gas in the tank before I left the house so all the results are using 91 pump fuel. |
