This weekend I had an appointment at the dyno facility Brian Goodwin has been using for many years. It's a privately owned Dyno Dynamics tucked away in San Diego 65ft above sea level. Conditions over the weekend were not the best with air temps at 80* and ~65% humidity.
Set up details: "V-mount" C30-74 Rotrex 85mm Pulley = 9.7psi peak Junkyard BP4W with 3 seasons on it. BP5A Intake Cam ID1000cc Walbro 255 E85 Racing Beat Header Racing Beat High Flow Cat Racing Beat Exhaust https://www.miataturbo.net/attachmen...ine=1442260338 First run on off the street showed 220WHP at 9PSI, not bad! https://www.miataturbo.net/attachmen...ine=1442086850 After getting the fuel curve dialed in and I started to play with timing, it didn't take much to hit my power cap. Last run of the day put down 235WHP and 190WTQ at 9.7psi peak. The car would have made more power, but given it's age (3 seasons on a junkyard block) and the fact it is completely stock I stopped here. https://farm6.staticflickr.com/5658/...a8595319_b.jpg Dyno operated said this reads about ~10% lower than a DynoJet, either way I'm happy with the 235whp...the car has some serious get up and go now. |
Forgot to say congrats in the other thread.

Thanks! It is nice knowing I don't have that sitting in front of the radiator along with all my other heat exchangers. The struggle is real with a Rotrex. On another note, I'm convinced the dyno I used pretty much matches a dynojet exactly as it sits now. There have been a few ND dyno sheets popping up (using a Dyno Jet) laying down the same numbers as our ND did on the Dyno Dynamics. |
