Graveyard 274 vs FP2 cam dyno results
I recently swapped my cams from Graveyard 274's to the FP2's. I swapped because I was unhappy with drivability and lack of vacuum so no brakes. All I did was swap the cams and got it retuned at the same place and the same boost level. I did an overlay of the two pull so it would be easier to see the differences. I know people often ask about the graveyard cams as they are looking for cheap cams and this dyno graph reinforces the saying, "You get what you pay for". Here are the main differences and the dyno graph:
Graveyard 274's: -4 inhg(vacuum), bucking when below 2k, slow spool, hard to street drive so not good for DD
FP2's: -16 ingh(vacuum), no bucking, quicker throttle response, quicker spool, great for DD cars and track, more controllable idle
Graph info:
FP2 cams: Red lines on graph
Graveyard 274's: blue lines
dotted lines are torque
solid lines are HP
