lol man every time i see this "Serious about making power in your MSP or 3rd gen protege?Want a free flowing aluminum intake manifold? Click Here" i think of those infomercials.

lol im advertising for rich since i post all over the forums lol That and because im going to be testing one of the intake mani's

there is a difference between pressure level and airflow
flowing enough air to generate that power at a lower pressure level will not have the adverse affects of a turbo that requires a higher pressure level of air
you should be fine around 8-9...I ran 10 psi on a gt28 all day long with no worries
Are you 100% sure about this??? I'm running a GT28RS and wouldn't dare go over 7 psi with stock internals I started a thread on this exact subject.

And came up with this: 246 CFM is what the stock t25 is making at 10 PSI, this is the invisible line that most say is the limit for the non forged stock motor.
with 246 cfm being the limit then:
GT25 = 246 cfm @ 10 psi
GT28rs = 246 cfm @ 7.7 psi
GT3071r = 246 cfm @ 6.8 psi
Just the fact that we have somewhat of a guideline number, I won't feel comfortable crossing it. I'm not trying to replace this motor until I'm ready and have it planned

hmmm so im running 10 psi on a 28rs that flows like a 3071 so where does that put me lol

you can do as you like *shrugs*
I still have run 10 psi on a gt28 without any issues whatsoever...I have friends who have run 10 psi on a larger t3/t4 than I was running no problem (over a year and a half now too)
but yes, there is a difference between pressure and volume of air

Stock internals?? not forged, right??
When I first got this turbo on I was boosting 10 PSI, and man it felt great, But too many folks on here warned about running that boost and that it was really like running over 10 psi on the T25, which got me scared and thinking. I wanted concrete numbers to prove that info, which is why I started that thread I have linked. what numbers are you putting down running 10 psi? I know that the motor felt like a pissed off caged beast when I was running 10 psi. A true monster. But like a said fear kicked in!! LOL

i guess mine and your interpretaions of caged beasts are different because im at 9-10 psi right now and its ok its by no means fast to me tho. Dont get me wrong a 2nd gear drop puts me in my seat but i still want a harder pull lol.

my buddy with the t3 was running on stock internals
I was on stock internals with the gt28 as well
the t3 I was not, but I blew that motor due to not having a proper tune for that turbo...hit predet a couple times and it spun a bearing within 6 hours lol...thats what I get for being impatient with microtech though *shrugs*

so are you ditching the t3/t4 for a 3076 now?

I 100% agree
the 28 was a disappointment to me...spent close to 1300 on it and only got that small of a gain really made me sad lol
but the t3? hot damn that thing is fun with that!!! (dance)
lol, I'm gonna be selling it soon if your interested in upgrading =P I'm going to a gt3076r
edit: got ninja'd lol
yea upgrading to a gt3076r at 25 psi is the plan, I also got a few other plans/tricks up my sleeve that I'm not revealing till its done =P
