Zero PSI turbo

The reason you ass felt more pull while you were boosted & @ 0 psi is because you went from negative to almost a positive pressure. That & the factory ECU started to dump more fuel to compensate for the added air that was coming from the turbo......

Let me tell you a true story. When I was 19 yrs old I worked in the electronics department @ Sears. I sold a VCR to a guy & the next day he came back & said the clock did not work. I said that highly unlikely let me check is out. He said "son I have an Electrical Engineering degree, I think I know how to set a clock" , I told him "well sir Im a high school drop out & as you can see I just set the time on the VCR". My point is dont toot your own horn cause you worked @ Toyota &/or attended school. Einstein dropped out of school when he was 16 yrs old. He was smarter than everyone put together on YW. If you were so smart you would have not asked such a question in your OP.........

Ok, but when you make a post stating that it can't be done, yet it's used on internal combustion engines, what am I supposed to think.

Then you post that you don't know if an NA engine reads 0 psi g at WOT. Maybe it's best you don't post about thing you only have street smarts in. Just because YOU've never done it doesn't mean it can't be done.

Read my first post:
That is not possible. You cannot run less boost than the W/G allows. Unless you use a pop off valve that bleeds boost. Good luck finding one that can go that low....

I specifically said how it CAN be done. And as for not know if a N/A engine reads 0, I meant it towards our engine, the 1NZFE.

Whatever man, sorry I even started this thread. I obviously have NO clue about how an internal combustion engine works, or turbo, or pressure valves, or physics for that matter.

Peace. I'm done with this thread.

Dude you sound like a kid who get mad while playing with other kids & picks up his toys & leaves. I never said you know nothing. You obviously know about transmission since you converted you car to a 6 speed. Cant we just have a civil discussion?

I like it when people think outside the box. Always stimulating to mentally stretch and think about new things. Got no problem with that.

Just don't claim it as a fact:

It would give the car a massive boost of torque without the problems

Is there agreement that there are no real-life examples, used on cars, of the set up you describe, with data to back it up? If there are, I'd like to see them. That would be a great starting point for how to implement it on the Yaris.

oh man, I just read #23.

You can set the psi to be 0 and yes there is a difference in tq over stock. Not by much tho. Is it worth the time? No. Why have a turbo to run 0 psi?

Really? How exactly? How can you set the psi to be 0?

My turbo is internally gated. I control my boost lvl via a counter spring. I can set it as low as I want actually or as high.

You can disconnect your wastegate acuator rod... Result is 0psi...

If you internal W/G flows enough that might work.....

Jamie you don't have to be sorry for this thread ! You opened this thread surely to get opinions from us and it always happens that people do not fully agree with our theories.

I cannot say how this 0 psi turbo setup could be and I am curious if this can be done infact with positive results although it's a shame putting a considerable amount of money and having no boost at all!

Although I am sure this can be done and with correct calculations you can gain something from it for sure. The only problem is Money wasted vs Power/Torque gains

All you'd have to do is take an existing system, like the zage kit sold at Micro Image, modify the spring in the waste-gate and add an electronic boost controller. It doesn't mean you're locked into not using boost.

I just thought up the idea from guys using the supercharger that can run with the clutch turned off to save gas. It's just that a turbo is more efficient on a small displacement engine.

Is anyone going to answer post 25?

How do you make more power or torque without any boost though?
To attempt to answer cali's Q - I've never heard or seen any automotive application with this set-up, they all make boost

Although, with that set-up, you could use your controller to only run say 3 pounds and be safe for your engine

Your car is still in vacuum @wot so 0 psi is more than what the engine would under normal conditions. Only way to bring you n/a car close to it is to free up all the restrictions in the intake system.
