Scroll down on the first page and you'll see dyno sheets from an Acura TSX and Lotus Elise. If NST can make power on a Lotus, you think they can handle your Yaris?

That's what I want to see 1st. The Lotus graph looks terrible, what happened at 6k? As for handling my Yaris, I'm sure it's worth a little hp, but I wanna see the curve. I'm also sure that Toyota wouldn't leave more than a couple hp on the table in a market that is so closely matched.

Why do the Lotus graphs look terrible? The Lotus Elise and Exige are basically track ready cars out of the box. The Elise has some of the lightest and most efficient OEM pulleys I have ever worked with, and NST pulleys still provided positive gains.

What happens around 6,000 RPM is the Toyota Variable Valve Timing (VVTi / VVTLi) that kicks in. The engine makes a lot more power from 6,000 to redline, as evident in the graphs there.

The same thing can be seen in the dyno chart above posted about the Civic Si and the Acura TSX. Vtec kicks in around 6,000 RPM and power increases significantly.

As you can see, NST pulleys continue to free up power even beyond this point.
