14b psi

[its_hey_ma]

Whats the lowest psi possible on the 14b turbo, assuming the wastegate is hooked straight up to the turbo outlet thing

10ish

i thought it was like 6 or 8

I was thinking it was like 6 too, but I was wondering if anyone really knew

When I was testing mine a while ago, I remember my 14B would go to around 8 minimum.

alrighty, thanks for the responses. I guess I'll just hook it up and see what I get out of it. If its higher than I'm looking for, then I'll just lay off the gas pedal a little bit

Why are you needing it so low?

 

[Hondahunter_666]

I know that mine wouldn't go under 9.5psi but I have a manual boost controller closed all the way. I believe that's as low as the wastegate will open though.....?¿?

The lowest it will go is if you take the boost controller off and just connect the lines together

I'm working on a custom turbo project for a different car (Hyundai with mitsu motor) and I'm using the left over parts I have from my 1g. I only want to run about 6psi though, which is why I was wondering if that was the 14b's lowest

I geuss im the only one running 7 psi on a evo 16g

7psi on an evo 16g ? y

When I got mine installed, the max I could reach was 8, nothing more nothing less. Then i got a T in between and got around 10-12 psi's

Still waiting on the profec

Wow... If you think your going fast with that, wait until you turn it up to 16+!!

As for the lowest boost on a 14B the wastegate spring is a 9psi spring, might differ a bit on some cars due to cracked housings and what not which would result in seeing a slightly lower boost... I was getting about 7psi with cracks at the flapper..

With no boost controller the lowest boost you could run is determined by the wastegate actuator spring, which on a stock DSM is around 8 - 9 psi. You can buy aftermarket actuators with lighter springs.

thanks, that was what I was looking for. I might look into lighter springs for the actuator

And if you want really low boost -- like none -- just take the actuator arm off the flapper lever so it flaps freely.

You won't build any boost because the wastegate will always be open.
