Micro Image Intake Manifold thread - Toyota Yaris Forums

Intake manifold notes and specs from today. As always, you can count on full disclosure and 100% information when we have something to show you.

I'm pretty happy with the results.

Our manifold made some nice power in the 3000-5000 rpm range, where most people will use it well. With some tuning, the top end will yield some power as well, AFR went pig rich at 5500+

ambient temperature was 90 degrees F

87 octane (91 would have helped us)
tested on a stock Yaris
Engine and bay were hotter for the pulls with MI manifold
Dyno Dynamics (tough dyno with numbers, 10-15% lower than DynoJet)
***some changes and improvements to be made in production
rich on top -- will deliver more power with some tuning
no CEL's
sounds badass

Here is the dyno chart (sorry for the large image). Grey is MI manifold, the other line is stock plastic mani. Chart shows power and torque comparisons.

here's a YouTube vid:
