tooter's next manifold adventure...

[Silver Streak]

Bummer great mod, but out of my price range right now. I'm curious Tooter, what do you think the spacer would yield on a bone stock Yaris?

From the dyno tests I've seen, a stock Yaris makes about 91 horsepower and 91 foot pounds of torque at the wheels.

So extrapolating the results I got with my engine, the spacer would only make about 92 horsepower and 94 foot pounds of torque.

Note on the graph that the peak values for both hardly go up at all with the spacer. The biggest difference is in the profile of the torque curve, and that the torque peak is reached 450 rpm sooner.
