Dyno of Yaris LB w/ Intake, Header & Exhaust (Charts Inside)

[ChinoCharles]

How many of you guys talking like you know something have ever been in the same room as a dyno? 2000 RPM is a perfectly acceptable engine speed to start a dyno run at. The fuel economy thread is there for anyone that wants to hop on a soap box about granny driving.

I've seen plenty of dyno runs and it's been my experience when peak HP is gained, power is lost on the bottom end.

Starting off at 2000rpm is all well and good on the dyno. But on the streets, if I was always starting off at 2000rpm, I'd be on my third set of tires (instead of my second set).

If the mods were able to increase initial torque without taking away from the higher rpms, then I'd be truly impressed and quickly drop my hard earned money for the add-ons. That kind of upgrade would not only make the car faster, but actually improve fuel consumption. It might not make you kind of the racetrack, but it would make you king on the streets.

Sadly I gotta agree here. I want to go from 0-60km/h faster in the yaris. Not from 60-100km/h faster... you know what I mean?

Not knocking those of you after gains up top... just not what I want... and I bet the majority of people would probably want 0-60km/h acceleration as opposed to 60-100km/h... cuz we're not tracking it, we are driving in traffic...

+1

Mods like the NST pulley set should increase power throughout the whole RPM range. I'll be getting that as soon as it becomes available (July apparently).
