Stay tuned

and I'm sure if they weren't restricted to certain stock parts it would be even higher. TB, intake manifold... ect.

hmm, Ok I sit corrected.

isn't the old dyno before cams and management change, though?

Yes it was. I think the head and cams yielded a very small return.

Bolt-ons and the Camcon will get you 90% of what we made. For the rest you need to get past the rev limiter, the AEM got us that, and better control of VVT-i, this is where the next chunk of power came from.

With our Level 2 prep limits only allowing us max .390 cam lift, and port matching 1" in, we did not make a lot of power on the head. There is still a lot left in there, but as long was we race the car in H Prod we can't go further into the head.

moar redline?

All of the parts are listed in the story in SportsCar, there is a link to download a PDF of it in this thread.

In a nutshell - the power stuff:
AEM EMS series 2 - you need the ability to control the VVT-i/fuel/ign to make all the other parts work to full potential. Without a tune you will get minimal gains from the rest. This car was originally tuned for economy and reliability, there is a lot of power that can be unlocked with a proper tune.
Okada coils
K&N intake
DC header/Coast Fab muffler/no cat
SPEC aluminum flywheel
NST pulleys - these were on when we did the dyno runs, and for most of the season. Once we started running 7300+rpm on the track the crank pulley failed, so we went back to stock.

Awesome, thanks Jason. Your car rocks. Finally some motivation to try and pull some N/A power from a 1NZFE.

am i reading this right? you had the NST pulleys installed, then when u tweeked the engine and started running higher revs the NST crank shaft pulley broke? how bad was the damage?

also, im assuming that the NST pulleys are a bad idea for running past the stock rev limiter then?

this worries me cuz i just installed these guys and i autocross. sometimes on a quick straight i will stay in second and let the rev limiter bounce if there is a quick turn not to far but would be losing time if i go to third.

I would not worry about these at all on a car with a stock limiter.

[cali yaris]

If you're on your rev limiter, you are at around 6250. You can't run past the stock rev limiter.

Jason's pulley broke in two, completely destroyed. Pretty sure a pic got posted.

[ilikerice]

^^ ok, good, thats what i was getting at... i dont plan on adjusting my rev limiter unless i do some serious head and bottom end work which probably never happend.

[why?]

so is the hood used on the car a seibon one for a yaris as the article stated, or is it something else like you seemed to say in your post?

I have no idea what post you are referring to, or what you took from it. Some things are made purposely vague until the publication is printed.

The hood and hatch both started as production Seibon OE replacements. They were modified to suit our needs, including a sizable weight reduction accomplished by removing most of the fiberglass support structure they use.

[cali yaris]

I know he skeletonized an existing hood, don't know which one.

Good stuff Jason. I'm crossing my fingers you get to race it another season. :)

Just got back from Toyota... Happy to see nothing got broken or stolen while the car was on display.

Now I get to reset the suspension, mount up some more tires and head to Willow Springs next week. The VP's from Toyota and Sony are going to take some laps in the Yaris... And the quickest of the Sony guys will race it next month in Phoenix.

Got to see them unbox a test mule while we where there. Comes in on a flatbed in a crate. When they opened the create it already had all of the camouflage on it. They go to a lot of effort to hide the lines of a new model. And no, it was not a Yaris.

Well, I for one LOVED your car at SEMA.
