Maybe you could get 20psi when you unplug the wastegate!!! Turn your engine into a bomb and watch the pistons fly. The crappy T-25 is just that, crappy. Mitsubishi was smoking some bunk sh*t when the decided to go with the T-25. It does spool fast but in runs out of breath faster than you can say :rice: But anywho, the little bastard can't even hold 15, 14, 13, or even 12psi to redline. But you wouldn't really want that pressure because it is at a very high temperature. Also the T-25 can't take the loads put on it at high psi and you'll burn out the turbo really fast. It was an 11psi turbo plan and simple. Get a 16G or FP BIG 28, or the whole other range of turbos perfectly capable for making the boost you want. JUST REMEMBER PSI ISN'T EVERYTHING. HONDER TYPE PEOPLE ALWAYS GET THAT WRONG!

Though, PSI does play its part. :scholar:

You can hit 25 psi but then it fall real fast. I run 20 psi at the track but then end up running 12.5 closer to redline

 

15 psi is about the most you will get efficient boosting out of a T25. Maybe even 16. Run it at 20 and you will over spin the turbo and burn it out in a hurry.

Its about efficiency. The T25 isn't, especially not at 20psi. Even on race gas and with a big ass FMIC, you won't see that much of a hp increase going from 15 psi to 20 psi.

 

What Tevenor said

the T-25 is not efficient at anything past 17psi, after that you're just blowing hot air and pushing less horsepower than you could. You could possibly set it up so that it spikes to 20psi (on race gas of course) then falls to around 15 or so in the higher RPMs', but for street, 17 psi is as high as you ever want to go.

 

Trust me you can run 20 psi. i run it and I gotten a 13.6. You just need to shift a little early.. You can do it thou. :happy:

You can bang a fat chick too but would you want to do it? Probably not. Same applies for a T25 @ 20psi.

Remember the old saying: Banging a fat chick is like running a T25. Sure its fun every once in a while but you don't want your friends to find out.

 

nice

 

That just wrong man.. No banging of fat chicks for me.. Why do most guys refer to car and girls.. one is a machine the other is a living breathing body.. If i turn up the boost and run a good time I've got to be doing something right. But there is no pride in banging a fat person. But getting a better time then most people with twice the mods priceless.. Yes I did bring the dam master card thing into this.

 

a quote not of my own...

"fat chicks are like scooters.... there fun to ride until your friends find out.."

 

Oh so you can get 20psi on the T-25 Wow that's really neat. I bet it pulled hard. :hail:

I bet it felt like zzzz


Anyway it is a stupid ass thing to do. I bet I could destroy your car running 20psi against my 15psi. Did I mention I had a 14B. Oh sorry.


Stick with the T-25. Its really cool. Keep running 20psi and you won't even be able to beat a Honda let alone the neighborhood kid on his bike cause you'll be walking.


Rob

 

I ran 18psi on my T-25 for two years solid, before upgrading to my FP Big28. It had no shaft wobble or leaks, and I was able to get a "whopping" $125 bucks for the little bastard. LOL

 

i love how ignorant people post things they have no idea what they are talking about.. if anyone saw my reply to another post i ran 16 psi with the t-25 at 14.3-4 everytime and at 20psi 14.1 everytime.. you can even feel the difference.. oh and if your worried about the turbo blowing up or something.. mine went 110,000 miles on the stock one and i was running 20psi daily on the street for 2 years.. great egt and a/f ratios too.. never an engine problem with 110,000 and still goin...

I ran 14.2 without a boost controller and with the stock exhaust. What's your point? I mean for crying out loud, and for once I am not trying to be a dick here, but ET's HAVE ABSOLUTELY NO BEARING ON POWER. What was the MPH on both those runs? That will tell you if there was a big difference in HP.

Remember, torque is what you feel and hp is what gets you there.

Either way, if you want to run 20psi, run it on another turbo. The T25 wasn't meant to run there.

Dude what you problem???

Ya 13.6 at 99.9 mph is slow.. ya I was falling asleep behind the wheel on that one. Also that fine you 14b vs. my Big 16G. Opps did I forget to update my mod list.

And FYI I was beating Z28 and I even got the pleasure of beating a 2002 yellow T/A.. That guy felt bad after that one. I think that you can make decent power out of the T25 But I wouldn't stay with it.

Wow the smartest thing I read all day. Hmmmm 13.6 with the T-25? Very exclusive club.:hail: What mods allowed for this isolated event? 6k dump I bet.

My problem is people thinking 20psi on a T-25 is a good thing. 20psi on a T-25 is like a limp dick at the Playboy Mansion.


Rob

 

Could somebody answer this?

Everybody says over 15 psi (at the manifold) is not worth it with the t-25.

Since the stock intercooler has a pressure drop of approx. 3.5 psi couldn't you get a front mount with top to bottom flow. Some of these have a pressure drop of approx 0.5 psi. Then your turbo is creating 18 psi (at the manifold) and working just as hard as it was with the stock intercooler and at 15 psi.

This is assuming you upgradded your fuel system to handle 18 psi.

 

he didnt ask for your opinion on the t-25.. he asked if it was possible.. yes it is possible..not very efficient, but possible... my point is it was faster.?.? you cant figure that out? and the mph was 1.7mph faster.. thats the difference... its kinda like the difference between your 14b and my big 16g ported and clipped from tre....

 

Okay here is a summary of this wonderful debate...

20 PSi on a T25 can work for some setups, but no matter what setup you are running, you are putting stress on the turbo and possibly the engine. It may hold up, it may not, so do it at your own risk.

 

Wow the only difference between my 14B and your Big 16G ported and clipped is only 1.7mph faster. :rockon:

Oh wait that's no good.........I got more money than you too now.

:takethat:

Oh and most of the posts around here ARE OPINIONS

Stephen nice summary. I couldn't have said it better myself.

Rob

 

Christopher Reeves might walk again someday thats possible. Mount a hair dyer on your intake and turn it on full heat, same affect. You want to move more air at lower boost. Less heat. What happens when you compress something? It speeds up the molecules, and thats my physics lesson for the day children.:created:

 

HEY!! Fat chicks need lovin too!!





Just not from me.

 

This is one of the dumbest threads I have ever participated in. I am now dumber giving my opinion.

you know were going to hell for this... but i was already on my way there

 

up to what sustainable boost is the stock turbo? I know a lot of people recommend on a 16g but I wanna max out my stock turbo first, how does the stocker hold up at redline or nea redline driving?

Okay to get back to the tread hear. First off, you can run a T-25 to 20 psi, But I never ran that on the street. I used race gas and sprayed my SMIC down with alcohol and a few other tricks. I also have supporting mods like full exhaust and intake and IC piping. If you don't have thous mods then I wouldn't run 20 psi. Why wouldn't you try to get the most out of your stock turbo..

First off, What the hell are you smoking... That got to be some good shit.

A Big 16G flows 550 and a 16G flows 505 You not even close to that you like in the 400 or somthing.. I don't know the flow numbers might be closer to a small 16G. The wheel are different too. The 16G uses a TD0-5 exhaust wheel plus, The Big 16-G is 1.89" at the inducer and 2.68" at the exducer. That is just over 5/16" (8mm) larger than the normal 16-G. And this only comparing a 16G not a smaller turbo like the 14b. You do have more money then me or maybe, or not enoufe money to spend on a better turbo.. Which one is it? When you say somthing like that, I think that your running out of stuff to say.

Also this 20 psi thing is from expericance. I'm not second guessing it or hear it. I've done it.. So go ahead and dis me all you can and tell people what you you think. I'll tell people what I've done. I don't really want to fight with you about this topic. Guys enough with the fat jokes.. zzzz This is a car club.
