RRev Motorsports in PDX was having a charity dyno day today, so I took the Miata in. Based on the following chart I expected to see ~115 or so WHP, figuring I'd see a peak 5 or so whp over this I/H/E chart. http://www.flyinmiata.com/tech/dyno_runs/Dewaine_Norris_082099.pdf
Imagine my surprise when I beat it by twenty-three HP!
I hit 132.3 peak HP, and 110.2 peak tq.
Power peak was at about 6750, and is a 45 degree line up the chart. No dips, lulls or otherwise.
The tq crests 100lb/ft at 3400, and doesn't fall back under it until 6900!! RPM
The air/fuel failed to impress me though. All factory fuel management, 130k miles on the pump, etc. It stays at 15:1 until 4400RPM. After that it takes a gentle decline to 11:1 from 5900 to 7000. Time for better fuel management.
The charts are attached. Sorry for the crappy camera phone pics.
My engine Mods: (just the usual bolt-ons)
