TTR Yaris Turbo 2015 Updates

[fnkngrv]

Today was a nice day so I was going to take her for a much needed bath to get the shop grime off, but alas the battery not being used much didn't want to give me a start so put her on the charger for the night and will do it tomorrow. While out in the garage tho I did snap a few more shots under the hood.

That's a very thick radiator, who makes that for the Yaris? The radiator mounts on the sedan are the same as the hatch?

It is the 90-92 Honda Civic EX 3 core. Fellows from the UK clued me in on it. Bottom lines up fine. You just have to fab an L bracket top loop mount for it and then use a straight section of hose for the top return line to the rad. So far it has dropped my engine temps by roughly 25° under normal load alone.










Here is a link to pretty much what I now have:

That's awesome, thank you.

Not a problem. AFAIK it will fit both the sedan and LB the same if not very similar since it is a half rad.

Have to take the car 60 miles to the local stealership for the 3 outstanding recalls (seat rails, spiral cable, and window controls) tomorrow so worked on the Cold start a little more.

Today was in the high 30s, but still she starts hard. Working with all the air flow that has been increased in cold weather makes for an interesting start.

Cold Start 20160107

Oh man, that cold start definitely needs some work.

I'd definitely recommend throwing a resonator on to further reduce the noise. It will really help to knock that "raspy" tone down quite a bit.

What's the AFR?

Pig rich tbh. Sitting in the 10s and 11s. The colder ambient temps aren't helping any that is for sure. Doing some work on it over the weekend.

Sounds a bit off but mean as all hell, when you go to the dealership tell us the expression on the techs faces after they see/hear you pull in lol.

[47_MasoN_47]

I'd love to see the expression on their faces as well. I've still gotta get mine in for all those recalls too :/

[malibuguy]

I just love this car

[Freestylin]

fnkngrv, mad props for this crazy setup! I absolutely love the way it sounds as it sits right now! Keep it up!

[fnkngrv]

Did some tune tweaking and made another cold start test today that was much more successful. It was 22° out also so that was a good sign. Also got a confirmation that the likelihood of the Dyno being available this month is very slim which is a serious bummer.

My apologies if its been asked already, are you tuning vvti also? Do you believe theres a noticeable power increase tuning vvti for your turbo setup?

[fnkngrv]

No worries. Yes we are also tuning vvti. As for differences there is a long story to being able to notice if there are differences or not concerning the Dyno work last year.

The short version is that due to an initial incorrect wiring install of the AEM boost controller and then plugged cat my tune and work done to it was seriously hampered. We wasted so much time working on those two items that granular manipulation for many settings were reduced by a great deal.

Even though last year's build/tune were an improvement and edged up performance/speed it just was a horrible cost/benefit situation. When it was said and done just the shop work/time at Granite State Dyno ran me close to $1500. That doesn't include the cost of the trip and GSD sits 400 miles from home. I had budgeted for half of that. With those expenses ballooning the way that they did further work was obviously hurt. We did do further analysis/tweaking during the speed runs with logger data, but just plain ran out of time for any performance improvement over the spring based tune. I only ran c12 race gas for safety as we didn't even get to really tune for it over 93 unleaded.

This time around I am working to have JRT Customs perform the tune at a much closer shop (200 miles) on the coast of Maine. The travel costs will be almost the same because we will be trailering the car and we will be around 10mpg with the truck/trailer. The Dyno cost and tuning cost will be where the big savings will be. I will have the Dyno for an entire day for a fraction of the cost.

On another note this new replacement AEM fuel pump seems to be getting louder very similar to the original one. I will be reaching out to them this week to discuss what is going on. An aftermarket fuel pump will be louder than stock, but even with how loud my injectors are you can hear the pump over them. Depending on what happens I may ditch the AEM and move to an Aeromotive unit instead. I have considered a Deatschwerks unit as well, but those are definitely loud from my research.

Before anyone asks after talking at length with Walboro engineers I prefer to not use one of their units for what my design is.

Is your AEM pump causing fuel pressure issues?
