Toyota MR2: MR2 On the Dyno Jul 9, 2005
Our 1985 MR2 Project took its first trip to Daytona Street and Performance on Friday for a baseline dyno run. Despite a stock intake and exhaust and an engine with who knows how many miles on it, the MR2 managed a better-than-we-expected 97 hp and 91 ft./lbs. of torque. From the dyno, it was a short drive to the exhaust shop for the installation of the Magnaflow can, cat and mandrel bent pipe, then a Saturday morning project produced and more freer flowing intake setup. We’ll visit the dyno again in a few days to see what kind of improvement we have.
One thing causing some concern is the extremely rich mixture at full throttle. A more fre flowing intake and exhaust will take care of this somewhat, but we may have to explore some other methods to thin out the fuel mixture a bit if this number stays too high.
