MR2 On the Dyno

Update by J.G. Pasterjak to the Toyota MR2 project car
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.

How's the Magnaflow sound?

Woah 10 year thread necromancy.

I fell like I violated history by reading that without noticing the date.

But how much power did it make after the exhaust?

Better yet, how much power does it put out now (2015)?

Damn, I thought it was the sw20!

I might be biased given that my build thread is for an '87 MR2 but I'd really like to see how this turned out and other general AW11 content.

In reply to sanman:

Can we request a SW20 dyno too? I'm looking into the GEN 4 swap myself for future reference.

Is anyone else freaked out by the fact that 2005 was 10 years ago or is it just me?

In reply to dansxr2:

Don't question just do it, you'll make more at the wheels with a gen4 than a stock mr2 turbo at the crank. And better drivability by far

Seeing as how I just purchased an AW11, I'd also like to know what happened worth this car. Are there other web installments from this project that got disappared somehow?

I was about to offer the build a fully ported 4AG head for a bit of mag space....
