Evo3 GT Max Boost

[5150]

I need to know what the max boost on an Evo 3 GT 16G IS.

 

[L2RTSiAWD]

What do mean by "max boost"?

The mas boost it is efficent at?

Which gas type? pump or racegas?

Everyones car is different there is no steadfast answer.

Im not asking the max boost with a certain setup, im asking whats the most boost that that turbo can withstand?

 

[leakyfaucet]

I'm sure the turbo can withstand as much as it can make. But your motor probably won't.

And it doesn't really make sense to push a turbo that far out of its efficiency range.

Ok, i wasn't planning on pushing it to its maxboost i just wanted to know what it could handle so as i upgrade my parts i know when its a good time to upgrade to a bigger turbo.

anybody know the evo 3 gt CFM flow? is it same as mhi evo3 or normal big 16g

The real Evo 3 can do 30psi, so it should be close to that...

30psi efficient? Where did you hear that at? I'm not calling you out on anything, just wondering where that info came from.

Nabr...

anything past 25 is out of its efficiency range.

you better have the correct fuel and supporting mods to even get close to 20 though. and i dont recommend using anything but 100 octane or higher past 20psi unless you have a really good tuning program and know what youre doing.

At 20 lbs/min maybe. The more airflow youre pushing the more power you'll make at lower boost. Unless you have a good setup boost isnt what you need to be worrying about - its your airflow.

Well at 26psi it flows 44lbs/min and in order to go faster the boost had to be turned up so I am assuming it was flowing more air at more PSI.

Log it and find out. Turning up the boost doesnt always increase airflow - esp if its past the efficiency range.

Whats the max rating on the Evo III 16G? 44 lbs/min seems pretty darn healthy for a small turbo like that.

I have datalogged 44.1lb/min at 7100RPM at 26psi on mine. Nice cold day. Intake air temp was 41F.

At 5259RPM, after the shift into 3rd, boost spiked to 30psi and I hit 42.1lb/min.

I'd upload the datalog of it, but the stupid forum doesn't accept .dat files.

Of course, this is the real MHI Evo III. Efficiency what?

Good to hear from someone with actual info here. I didn't realize the Evo3 would be efficient at that boost level. So much for the Evo3 only being "efficient for 20lbs".
