More Boost More Power

[Bass Junky]

0.9 Bar = 13.23 psi

Any tuned, advanced timing, 12.0 : 1 AFRs stock turbo (standard PFC tune style car) is a ticking time bomb.

A stock turbo, on stock computer will last a little longer because you aren't advancing the timing and dropping AFRs which both create heat in the exhaust.

Heat on ceramic exhaust wheel is just asking for a delaminated turbine entering your cat converter.

Guys i turned down the boost last night to 12psi...is that even a bit much 4 every day driving considering i still have the stock cooler or is the stocky capable of running 12psi day in day out????

i was talking to a guy with a 500rwhp r33 skyline who was telling before he built the monster he had that he ran his stock turbo on 18psi for 2 years and it was still perfect when he took it out of the car. He was saying that its all about have the supporting mods to ensure the turbo doesnt deteriorate eg a big exhaust to let the heat exscape fast, Good intercooler, ect ect. I wouldnt want to try it myself but he knows his shit and managed to make it work some how....

this guy u were talkin 2 wudnt happen 2 b from th gold coast would he.

i was talkin a fella there one night with a black r33 with 500hp who gave me th same bllsht spiel. 18psi for two yrs then put it on a rb20 cos it was stil perfect. he's a wanker mate. he told me running leaner would reduce my exhaust temps. the thing he thort was th coolest bout his car was that it stil had th standard head gasket. wanker

ive had my hi boost setting on my boost controller set at 14.5 psi for the past month or so only running that pressure every now and then and it seems fine. but i suppose prolonged use (track use)at this boost level may blow it. My bro also had a brand new r34 turbo put on his s2 r33 he was running 16 psi everynow and then for a year or two and it never blew. he has since upgraded the turbo after it was taken off we carfeully inspected the turbo and it is still perfect to shaft play scoring broken bits etc.

so i guess as long as you arent hammering your car all day everyday at 14-16psi the turbo will be ok for little bursts just to feel what a skyline would be like with a better turbo.

before any of you get all excited and tell me that what i am saying is bullshit. let me tell you that what i have said is actually what i have experienced and am currently doing.

my auto does not like it above 11psi or it pops de to fuel cut i think and if i turn it down on high revs i get a much better power band same mods as usual

This 14psi = kill turbo thing everyone talks about seems to be a bit of a bell curve if you ask me.

The majarity of them will die round 14psi. Some even die at stock boost and some just seem to take crazy amounts of boost.

Its up to you if you want to run more boost but the risk off it dieing will increase accordingly. You may be lucky and then again.

Also if it does die it could also at a very off chance kill your engine as the ceramic bits from the wheel do wonder to the bore if they get in there if you know what I mean.
