Safe Boost Level?

[kounj002]

Hi Just wondering if anyone could help me out. I have just had an Apexi AVCR installed in my car and im running 14psi constantly, I have a 3'' turbo back exhaust, HKS pod, and a Blitz FMIC I havent had it Dyno tuned yet but was wondering what others with similar mods were running and how much can I run all day everyday safely, any help will be appreciated

If you want a new turbo soon, keep it at 14psi, otherwise 10-12 is considered a sefe level for a std turbo.

Mine ran 14psi for 12 months befor I had trouble (but it wasnt the usual distruction of the exhausw wheel).

Talk about being right on the money, I went for cruise the same night after I left my post I and blew my f$%^&n turbo !...........Looks like im off the road for a while! What about the irony of reading the responses after blowing the turbo!....

Talk to GCG and get a one of their hiflow turbos. (unless you have big hp plans, the GCG will makw 260rwkw with the correct support parts.

hhhhmmmmmm.........i've been running 14psi on my RB20 since bought it 6 months ago, haven't had any problems as yet (touchwood!) and not running a FMIC either . Is it true that std RB20 turbos can run a few more psi than RB25. I hope this is the case otherwise I'm gonna wind it down to 10psi.

Adam mate i wouldn't be running 14psi on any car without a front mount! It would be ok for a while.........

[HR-32]

yeah its only got the factory fmic, the size of a matchbox (well almost), probably good for stock boost, yeah should wind it back to 10psi, will do it tonight. FMIC upgrade is number 1 on my list anyway. Feels like I am losing top end power even on full boost though, time for a service and tune, big 100k service!

i got mine dyno tuned, and it was set at max 10psi, but when i checked the ebc and look at the peak boost, it shows 0.86 bar = 12.4...somtimes its at .82 n i think i seen it at .9 b4...i dunno wast going on...any1 know how 2 use a blitz ebc?

[Cubes]

What type of blitz ebc?

The SBC or SBC-id?

I used to own an SBC-iD, if setup in auto mode it had to be setup on a dyno other wise it would have a tendancy to spike a little.

Manual mode that uses a plain fixed duty cycle and gain was always rock solid but with the smaller turbo would tend to drop boost at the higher rpm, where as the auto mode would monitor boost levels and adjust duty cycle in order to force it to hold boost.

Blitz DUAL SBC TYPE S

Have a fiddle with the gain setting.

All though you will still see 'slightly' different peak boost levels depending on air temp.

i seem 2 get diff boost peaks at diff gears....in 1st gearr i went to 5-6k and it peaked at 0.86, then i was doing 60 dropped to 3rd gear and got 2 5-6k and peaked at 0.72 which is a little over 10psi which is what it was set at....also was a cool nite last nite...

My Stagea is currently set at 12psi, with all the supporting mods. I never keep it held on 12psi boost for more than a sec or 2 - its the heat build up that destroys the ceramic exhaust wheel.

Ive got a spare RB25 turbo at home, so not too worried if she shags herself, but I dont think that'll happen due to my 1st comment above.

I had mine running 16 psi for ages on a new turbo an old turbo won't support 16psi for long maybe a week. ceramic turbos are shite! AND THEY WONT LAST LONG BOOSTED

[r31turbo]

the safe boost level is under 15psi. 16-18 and prepare for metal shrapnel. on std turbos. just read in hpi they have a whole table for loads of imports with the safe levels

[Maxx]

if u need to run "under 15 psi" u will need a tune, which keep the exhaust temp low

still a bit high for R33's turbo

Hey Im going to speak to the guys at GT Autosound on monday and see what they can do for me, If that falls through $400 is a done deal but i'll let you know! Is it a series 1 or series 2 turbo? My car is series 2

[vange]
