OVTune 3.5L Tacoma Supercharger and Twin Turbo Systems

Is that a Moto?

 

Yeah. The Ural that I had and got rid of just before the Taco. It was what set the wheeling hook for me.

 

Look at it this way.

- When the truck is in vacuum (no throttle) the intake manifold is pulling blow by gases out of the crankcase, and along with it: oil, water, acid, contaminated air. At this time the passenger side breather is pulling fresh air from the intake pipe (pre throttle body) into the crank case.

- When the truck is in boost, the intake pipe (pre throttle body) is now pulling blow by gases out of the crankcase. The reason for the 1 way valve on the pcv side is to prevent the now boosted (positive pressure) intake manifold from "leaking" boost out into the crankcase.

So when you are at idle, you have contaminants going directly into your intake manifold. When you are at boost you have contaminants going directly into your intake pipe. Normally this isn't that bad when you are N/A. When you add turbos you increase blow by gases.

A catch can on the manifold (driver) side is HIGHLY recommended, as this is the main outlet for your blow by gases.

A catch can on the intake pipe side is recommended as a safety assurance, especially if it's piped in before the turbo, because the turbo will pull those contaminants and oil into the turbo vanes. This will eventually muck up your turbo. This side "shouldn't" see as much blow by so a smaller catch can will work here.

You can run two catch cans (1 on each side), or you can run one if it's dual valved (3 ports). The picture OV posted above is the setup you would use for a dual valve. This pipes both sides through 1 catch can so it's pulling contaminants during each cycle (vacuum/boost). It's just a consolidation or a way to tidy up your bay. Neither is really better than the other. Both setups work.

It's imperative that you have that 1 way check valve on the PCV side though. If you run a dual valve can, you need two check valves.

It's a good, better, best scenario. No catch can won't kill the engine, only muck things up over time and hurt performance a tiny bit.

 

You know that honu (turtle) are considered good luck in Hawaiian culture so it's probably pretty good to have them riding with you on 2 wheels.

 

Yessir. A very good friend of mine is from the Islands. He donated the water bottle.

The only problem is that the printed stuff came off over time when cleaning it after dumping out the collected junk.

 

Under the hood finally done. (actually just need to add a check valve on the drivers catch can, and program the PWM fan).
It's crammed, Every inch is taken up.

Mat wasn't kidding the oil pan gasket is on there good. 4 flat heads later..

 

The install looks so clean. No red pipes and chrome clamps.

 

So I can pass it off as stock

 

If the intercooler was black or plastic covering then yes to a passerby.

 

"its a toyota ecoboost v6".

 

Hey wait a minute! Your oil pan was already tapped?

 

I really hope OVTune or MESO make a recommended mods and such with reasoning when everyone’s setup is done. I’ve got a lot of reading later when this stuff comes in

 

No, that's the last component I need. Everything underhood(or topside I should say) is ready to rock.

 

Time for street videos

 

looks excellent, and without the stock airbox there is so much room for piping.

 

Since you guys were walking about oil catch cans and such I think we will CNC our own for our TT system.

 

I don’t mind that at all! Just add it to my order lol

 

This would be perfect. I could then just sell my universal cans locally.

 

I like the idea of having something that can be mounted on top of the fuse box, or another easy to get to place.
That catch can pictured before is very nice, but taking the front grille pieces off to drain kind of sucks.

obviously this isn't what it will look exactly like because I made this model in 5 mins lol, and I can't promise I will even go through with developing it, but the general idea,
2x top ports go from each turbo post maf
those two supply fresh air via the left port to the passenger side valve cover (fresh air vent), that is divided from the vacuum side, inside the catch can
The right side has 2 ports (you can only see 1 in this image) that collects the vapor filled gunk from inside the engine, and exits through another port into the intake manifold.

This allows you to:
retain fresh air breathing through the engine that is post MAF measured
allows for collection of vapors before it enters the intake manifold
does not allow for any possibility of the fresh air breathers causing a vacuum leak.
requires only 1 check valve.

(model is for example..whipped it up in 5 mins. it won't look this ugly)

The stock setup uses a post Maf (measure air) breather on the passenger side, that feeds through the engine, collecting vapors, and exiting into the intake manifold, creating a closed system.

It's critically important the catch can does not create a leak in the system by introducing unmetered air.
Also very important that the catch can does not bypass the actual metered fresh air circulating through the engine before being collected.

 

Mighty nice welds sir.
