Honestly it MAY be more than that, but not much. A T25 can handle 18psi and that turbo is smaller than the T3. But yeah, better build the whole engine if you're looking to max out the turbo. Even then I recommend you upgrade the turbo at the same time. I don't think it's a good idea to run at the limits of the turbo on a daily basis.

You need to provide more information, such as what trim level the T3 is and brand (I'm guessing Turbonetics, but one never knows), because that makes a huge difference. I've got copies of the compressor maps for Garrett, Turbonetics, Innovative, and Apex'I turbos, so give me some more information and I'll take a look at the compressor map for ya.

Rep Power: 0 I have a greddy profec b spec 2. My settings are at 25% gain with 32% boost setting and i get around 6-7 psi...the thing that sux about this thing is that you can't do gear specific boost settings like apexi avc-r. So at every gear you have different boost...its retarded. But yeah...im not sure but i think it also matters what your turbo wastegate is set at stock. Mine is like 2psi haha.

Rep Power: 312 you guys dont understand. The psi has NOTHING to do with the turbo. The turbo makes CFM. and CFM is what makes power. Of course, the more CFM you shove through a small hole the more pressure you will have. Also there are many different types of T3's. Their power ranges go from about 220 whp max to about 450-500. The T3 i have on my civic can handle upwards of 450 whp without straining the turbo. Whether the turbo does it at 15 psi or 40 psi, it doesnt matter.

Rep Power: 0 yeah...but the freakin greddy profec b spec is so retarded. You set the boost by setting the percentage of the maximum flow of the turbo wastegate. So confusing...I stopped messing with it =\
gotta start again when i get my alc injeciton hopefully tomorrow

I don't think that's what he's looking for. Some of the settings on the profec b are based off of a percentage of the turbo's ability. I think he wants the numbers so he can set his ebc accurately.

Sorry if I wasn't clear on this guys I just need the max PSI (CATALYST
) that the turbo can put out. It's strictly for settings for my EBC. The very first setting is boost pressure as a percentage of the max the turbo can output. I don't really like the way it works but either way I bought it and I need to figure it out. The manual actually says:100% would be the maximum output of the turbo/wastegate.
100% could equal 20 PSI so I know at 25% (SET or boost pressure) I should make 5 PSI. This means I need to set another setting to 5PSI (SET GAIN to be specific).
BTW...off topic for this thread but where can I get Denso Iridium IK-22's cheap?

I am going to set my boost pressure to 20% or 5 psi for my low setting. Then I can set the boost cut off to 5 psi and be dead on! Thanks everyone for your help I'll let ya know how it goes.

Rep Power: 0 Yeah if you set it to close it will definately spike. Don't tune your thing by calculating percentage. Do trial and error. Set the gain at like 15%, and the boost at like 20% and start from there. See if it drops off at high rpm or if it spikes. Check how much bar of boost you are running. Keep raising little by little until you get to your desired boost. Your way will not work for SURE. Also if you set the limiter at exactly 5psi, u will be sad because if it hits 5, your boost will drop down and its really sucky.
