How do you determine the limit of how much boost you push through a turbo even with CO2 on the gate?

Current I'm running twin JGS 50mm gates with a FI S476 Gangster turbo. I have medium springs in the gates and it makes 7-9psi on WG. If I throw 30psi on top of the gate via the boost leash it will make 24psi. If I throw any more one of 2 things happens: there seems to be a limit in the leash because 35, 40 or even 50 psi will not make any more boost and it stays at 24psi OR the leash will reset at 30 and not allow me to add more CO2 (I only noticed it when I power it down and power it back up). I'm only trying to push 28-30psi which I know the turbo should be able to do and I've seen 25-26 before.

Any feedback? If I'm leaving out information let me know, thanks!

Size of the motor will make a huge difference on how efficient the turbo will be on any application.

you cant say its done without knowing the size of motor.we have 2 evo around here on a 6266 making 45+psi now throw that same turbo on my 357w and it would be done around 15-20psi.

Im not saying his turbo is or is not maxed out but you cant say for sure its maxed out until you know size of motor,heads,compression.

Iol what are you even saying. He essentially has the gate clamped..... It's not making anymore boost. I don't need to know the engine size. The turbo is done on the combo it is bolted to

If it was a 3liter and he clamped the gate it would make a but load boost, what's the point?

so the turbo is maxed out? That dont explain why the BOOST leash will reset.

Let's see... He said he ran up to 50 on the gate and didn't respond.

Turbo not done on a coyote?? ... Do realize what the VE of those motors is like? Obviously not

It was already running 165+ under 25psi... Yeah bet that turbo has alot left. Rolls eys

Jesus Christ. I can say it's done without knowing the motor because it doesn't respond to dome pressure? Are you dense?
