quick ques.... does anyone know how much psi the stock internals will hold? Also, i hooked up my boost guage and i T'ed the it to the vacuum line coming off the intake manifold right next to the brake fluid res. and its peaking at 17 PSI!!! WTF! I have some mods like intake, 3in downpipe, 3in catback, but why is it reading so high on the stock turbo! Any ideas.

 

hmmmmm.....no body knows huh.

 

Stock internals will start to break apart at like 450bhp. I say 400 is safe but it all depends how you have taken care of the car over the years.

 

you can take 22PSI off of a 16G and supporting mods(I.E. fuel tune and bolt ons) and you will make like ~300WHP

 

From Reading I've noticed that If i was to slap on a FMIC onto my stock turbo i'd loose power? Why's that? i thought it'd add colder, denser air = more power. how would a bigger intercooler hurt performance?

 

from what i've gathered, if you are running a small/stock turbo that isn't running much boost, all the extra piping actually kills the boost before it reaches your intake... unless you are running 10+ lbs of boost a FMIC isn't worth it. (correct me if this is off... i'm still learning damn it lol)

 

Ya, but don't the stock turbos boost around 12? Plus if you have a stock turbo you can boost the T25 efficently to around 15psi. so there it'd make sense right?

 

300bhp from 22psi? Sorry thats wrong. I got 297 from 16psi and a good tune. You can get much more than 300 out of 22psi i know it.
