Zero PSI turbo

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...

Peace. I'm done with this thread.

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.

Ok, i've never measured myself, but isn't it supposed to be only 1 or 2 in. vac (very close to 0) @WOT? I could see picking up a tiny bit, but nothing worth the money you would pay for a turbo kit.

cdydjded, you answered it yourself... This method would work perfectly if there is enough flow.

It's a cool idea but definitely not worth the hassle or cost.

If your wastegate is accessible it shouldnt take more then 5 minutes to pull the pin holding the arm.

Blue vitz, it is possible to do as you have suggested, I can think of numerous ways to do it. Restrictors on the inlet to limit air flow and boost, soft wastegate springs as you have suggested, pressure activated solenoids to bleed excess boost (may cause emissions problems though). All though have down sides and require more thought so that you could obtain a very low boost turbo setup with minimal losses at high revs.

I like the idea Blue, but there's no way I, personally, could keep a car at 0 psi boost when it could do more :D
