Safe Boost Level On Gtr?

[RRR32_GoDzIlLa]

Hi, i just received my new power fc in the mail from Nengun.com $1003.18 delivered.

I already have profec boost control tho not hooked up yet, was waitin 4 power fc to tune them together.

i cant afford to replace the turbos at the mo and need them to last for awhile. So how much boost should i be running.

the car will be jumping on the dyno in the next couple of weeks and wanted to know whether it would be safe to run a bar.

i did a search looking for how much boost is safe to run on Standard 33GTR turbos. (i have 32gtr with 33gtr engine/turbos).

found beerbarons stats, running a bar. Is that safe????

i need them to last but want the most power i can get safely...

A bar is the maximum boost you could run safely*

*Stock turbos have been known to give way at less than a bar.

Take caution

yeah, 1 bar is certainly as high as i would go on stock turbos, but that's not to say they will be bullet proof at 1 bar. 1 bar is generally just the accepted compromise between turbo longevity and increased performance. This is the mark for a couple of reasons. for starters the power gains start to taper off once increasing boost (on stock turbos) past 1.2 bar, so you are effectively then sacrificing reliability for not much more power. at 1 bar though you will have a nice power increse over stock, inlet temps will still be reasonable, shaft speed is still at the upper end of being reasonable and reliability should be fairly good. having said that, if your turbos have been pushed hard before, or had extreme heat cycled through them they may fail at any time regardless of boost, 1 bar, .8 bar whatever. But for good condition turbos 1 bar should be fine for quite some time.

ok. i'll tune em to a bar and hope for the best.

hopefully i won't be walking for the next 3months. lol

will post dyno results when i get the car back.

cheers for info fellas

any other tips..

a bit off topic here but oh well, i read in the pfc manual on this site in diy, that it comes with a boost controller.

im planning on getting a pfc soon and if i can do everything with the hand controller, without a boost controller then that would be good.

anyone know?

i dont really understand your question? the powerfc does not come with the boost contorl kit its a seperate option for an extra $300 ish. but it does plug into the powerfc and factory harness.
