DIY INTAKE - Page 4 - Toyota Yaris Forums

I'm going to be spending a lot of time on rollers if this car is going to have any kind of performance. Frequent trips to the dyno can be expensive, unless of course you sell your windshield as real estate. I'll never pay full price again, but I will put 20,000 miles on a year with that sticker on my window. Fair trade... TI can do some other stuff too, some of which I may look into soon.

She was so fast we had to strap her down!

...

I'm going to spend a few days stewing on the results. For you experts, here is one to tinker with in the meantime.

My car has an intake, header, and pulley and it is running rich. You guys all said it would run lean. What does this mean?

eTiMaGo · 03-12-2007, 03:05 AM

sticker looks good, you little dyno wh0re

, I thought you were gonna put it at the back?

ChinoCharles · 03-12-2007, 02:38 PM

I was going to put it in the back, but it fit so nicely in my window stripe that I figured I'd put it on the front instead. The back is already so clean, why ruin it? That would be as dumb as having a rear wiper on a Yaris.

OH BURN!

Anyone want to take a crack at these results? The car is running super rich now... I'm talking in the low 11's at WOT. WHAT DOES THAT MEAN?

My .02's worth: You've increased the amount of incoming air. In order for your cars computer to overcome this lean condition, it starts taking more fuel. In other words, a lean condition creates a rich command in the computer, and vice versa. I've never heard of just an intake swap doing this. When you mention low 11's, I'm assuming your talking air to fuel ratio, correct? Are your plugs starting to foul out, what do they look like?

asmodai650 · 03-12-2007, 04:07 PM

Don't want to hijack your thread, but I'm currently getting 35 mpg daily doing 75 on the highway and short city trips in my sedan. Gotta love this car.

ChinoCharles · 03-12-2007, 04:15 PM

Yes, we were running a low 11 AFR at WOT... and we have never heard of an intake doing that either.

That gives this intake some pronounced advantages and some pronounced disadvantages. One thing is for sure... I am going to see a rather substantial increase in gas mileage and power very soon.

Haven't looked at the plugs yet, but she is still running fine. I'll have to pull them out and take a looksie. They need to go soon anyway... time for some real spark.

Ashley, say something.

She sound much throatier now... thinking about putting a breather on the crankcase orface tube and plug the hole in the CAI so she breath fresh air

jdubau55 · 03-12-2007, 09:25 PM

Here you put it on the dyno then "stew" on the results. Bastard.....

here is the b4 pic... the filter sat just under the headlight

I promise you you're the only one in the country with the betTRD.

Gotcha..... I just call it a TuRD

blake111887 · 03-13-2007, 02:43 AM

wussup chino, low 11's huh? thats pretty cool man, dont know how you did it but you did. your on to something man, i just cant wait till you start producing it, cuz im definitely getting one. and the engine sound pretty damn beastly btw your bringin a whole new light to the 1NZ's.

ChinoCharles · 03-13-2007, 03:10 AM

Low 11's when it comes to your air-fuel ratio, not quarter mile times if that is what you thought I meant.

My car is definitely faster with this intake. The graphs prove that much. Peak HP increased a bit and torque stayed pretty much the same, but the difference is in how soon I am getting power and how late I am losing it. By about 3000 RPM I am within 3 ft/lbs of peak torque, and that doesn't change until about 5200 RPM. That makes me extremely happy.

The kicker is the AFR readings with the new parts... still not sure what to make of it. We will see what it is with the exhaust on.

eTiMaGo · 03-13-2007, 03:29 AM

AFR numbers look pretty much on par with what I am seeing.

I'd be curious to put my stock air box back on and see if there's a difference...

ChinoCharles · 03-13-2007, 03:31 AM

Yeah, but your intake is weird. Are you running a wideband? You should throw the stockie on and see what happens... takes 10 minutes.

Pwetty pweeze?

I may help throw Joe's car on the dyno this weekend. If that TRD intake runs rich, watch out... I am going to explode.
