So over the weekend our Miata club event here in CT was a dyno day and I was excited to see the results of my Exhintake mod that I painstakingly labored over because I wanted to make sure I did it perfectly. I have a '96 1.8 with a randall cowl intake, exhintake mod, and 78k on the motor and I topped out at..... 99.4whp and 99ft/lbs. For reference, another NA 1.8 that day with just an exhaust, no other mod and lots more miles on motor, recorded a 113whp. Does anyone have answers as to how this could happen? I am running 18 degrees advanced, and I am going to back that off to 12 or 14 I think, but would it even be possible that 6 degrees of timing is worth 15 whp? or is something seriously wrong with my engine.
