Oil catch can.

When you go boosted the rule of thumb is 1psi of fuel pressure per 1psi of boost. The fuel pump delivers more fuel to the engine than it actually needs in this scenario. The excess fuel is then routed back to the fuel tank through a pressure regulator and return line.

A returnless fuel injection system, by comparison, manages fuel pressure a little differently. Instead of using a spring-loaded vacuum diaphragm in the regulator to change fuel delivery when throttle opening and intake vacuum change, the regulator in a returnless system operates at a constant pressure.*

Thanks for the explanation, makes sense.

For the oil catch can, would the breather filter on it not cause a vacuum leak as it is no longer a closed system?

No. The pressure needs to either recirc or vent to atmo. When you aren't using a catch can to collect blow by the pcv handles it.

I see. Are you using the vacuum line that runs from the pcv to feed your catch can? And if so did you remove your pcv or do you still have it installed?

I'm currently running a catch can from my pcv line with the pcv still installed which feeds back into the intake manifold (no breather filter so it's a fully closed system). Catches about an ounce or so per 10,000km. I'm curious as to how you have yours set up w/ all the extra boost

My lord, look at that! Traction is only going to be a dream after that monster fires up lol. Judging by how fast you guys are building her, this will be one heck of a gift for yourself and the community. Can't wait to see how the down pipe and exhaust will look!

Definitely a good point. How are you going to handle it? Does the EMS have traction control?

It will be a learning curve no matter what with the conversion to cable TB since it will be instant throttle response. I know that when Garm took me for a ride he was having difficulty hooking up to a point with his LB. AFAIK his LB actually had a Motec EMS and not AEM so that may have been a contributing factor. There are still a ton of features I have not tapped into with my EMS.

Downpipe was already completed.

As for exhaust the middle 4' with the cat will be v-banded so that when I race I can remove it and put on a 75° dump tip instead. I had kicked around doing an electronic cutout but after tons of research decided to ditch the idea.

Ahh you're right, barely can see it with the wrap on it. What muffler/resonator are you going with?

Bbbwwwuuuuhahahahahaha.

Oh you were serious ;-)

None. Only will have the Vibrant cat and straight pipe.

Actually, his tC has the Motec, and I kind of hate it. It's comprehensive, but it's dated and I absolutely hate that Motec hides additional features behind a paywall ($180 for traction control, $800 FOR CLOSED LAMBDA TUNING - I MEAN C'MON REALLY?)

His LB had an AEM EMS, but that doesn't necessarily mean traction control was tuned since it's more work. The good news is that even if you throw on really wide tires, you probably won't be in tram-lining territory.

fnkngrv · 12-12-2015, 09:14 PM

Traction control in a stand alone can only go so far anyway since it isn't tied into the actual suspension on this chassis. Only time will tell on how this goes. The few other sedans I have seen running serious power essentially have to have a very specific tune to maximize take off and gear change performance.

Battery relocation and exhaust have been completed. Did a first start up this afternoon:

Tiamat 2015 First Start

Hard to believe that the car has been off the road for over a year! This is a quick video of the new setup at first start. Seem to have a fuel pressure sensor issue or something as the gauge isn't reading correctly compared to what the EMS is showing so will need to figure that one out. Next step will be getting her loaded up and brought to the dyno hopefully in the next couple weeks.

LTHatch · 12-13-2015, 08:38 PM

Holy space balls, that doesn't sound like any econobox i have ever heard lol. Sounds amazing, you did an outstanding job on your Yaris.

Is the exhaust hitting the rear tow hook?

fnkngrv · 12-13-2015, 08:43 PM

No, but it is pretty close. That is the problem with this body kit to be honest. We do have one hanger left to place on the passenger side and then the dummy pipe on the driver's.

LTHatch · 12-13-2015, 08:55 PM

Ahhh ok, in the picture that shows your rear springs, what the heck is in your right rear spring?

fnkngrv · 12-13-2015, 08:59 PM

I have spacers in the springs because the body kit actually drops the base of the body by ,1 1/2" compared to the stock S lip kit. Eventually I will get my tanabe coilovers in, but it will have to wait as I am getting pretty tapped out now from the build.

What an awesome sounds. When your Yaris was cranking and something hit the floor I thought it was your engine...my heart skipped a beat for a minute until I realized that your engine was still turning over fine
